Last night I installed the new Matco axle in my RV-10.  It

looks like it should work out way better than the original.



http://www.myrv10.com/N104CD/upgrades/20090120



 From my perspective, things started off truly unsafe and

miserable.  This is now basically my 4th "try" at making

things perfect.



#1. Stainless spacers - trashing my fork

#2. Large washers protecting fork, Stainless spacers rotation

	locked.....much better from a wear perspective.

#3. Use Van's new parts provided after SB was put out.

	This was a better situation than the original by FAR.

	But, it is also far from ideal, and is pretty crappy

	from a bearing preload perspective, and they STILL

	didn't provide anti-spin for the spacers.

#3. Matco's replacement axle.  It's far nicer, and basically

	fixes all of the issues that the original one has.



I would encourage all of you RV-10 builders to at absolute

minimum, do some sort of mod to make Van's spacers anti-spin.

You will still have to do far more checking of nosewheel

bolt torque if you want to prevent issues over time, but that

in itself would be a step up.  But really, for the low cost of

this axle, I think it should just be one of those things that

everyone does....just like the axle extensions on the main gear.

Don't wreck something or live with a poor standard design.

I'm not sure if the backlog is shipping.  I ordered the

weekend before it was known by most people that they were

even available, and my order was one of the first in.

I think they ran out right away shortly after.



I did just get a little feedback from George at Matco

tonight, who I sent the link for the write-up to.  He

says the following:

------------------------

"The installation drawings are also linked on our website on the 

WHLAXLE24 product page.



Did you balance your tire?  It made a huge difference for Scott and is 

easy to do with the center hole in the axle.



The wheel for the 5.00-5 tube is the WHLNW511.25.  It is machined 

differently to accommodate the longer stem on the 5.00-5 tube.  We offer 

an inexpensive exchange (under $20) for those who have not yet mated the 

tire.  We can replace one half of the wheel if the tire has already been 

mounted for about $60.  The wheel needs to be sent here to have it done.

There you go, more info to consider, if you're building.

Actually, it was all just a standard purchase for me.  Scott Schmidt

was at the same airport as them, he got one installed with them, so

that they could do it right.  We talked on the phone about the design

and he filled me in on it.  I asked him to find out how much $$,

so he checked into it and I got a reply that it was available for

purchase on their website.  I hadn't ever even talked to a person

from Matco until they called to let me know it was shipping.  And,

I even had to contact them AGAIN, because when they billed my credit

card, the sale price as listed on the site didn't get incorporated,

so I had to get a credit for the sale price.  It was when they

called to let me know it was shipping that I told them I'd give

them feedback once it was installed.



So, just to dispell any myths, they didn't provide me any product

for free, no special pricing (other than the standard sale price),

and gave no incentive whatsoever.



For what it's worth, the same goes for almost everything that

I have in the plane...there were a couple things that I got in

exchange for some help in development or being the first to

flight test something for the manufacturer (most of which were way

back 3-4 years ago now), but I've never been paid for promoting

anything, or for a write-up.



Looking back at my website for some of my favorite little things

of recent, I can say that I got nothing for it....such as:



Matco Axle

Voyager software and related items

Slick Mag parts

NavWorx ADS-B

Mutt Muffs

Brake Lines

WSI Wx

CO Guardian

Chelton/Pinpoint stuff



I'll discontinue listing at this point, but the point is,

none of those vendors paid anything for any reviews or write-ups.

By being persistent, or jumping on something as soon as it was

available, I've often been able to be at the front of a queue.

In the case of the Axle, once Scott told me that it was an

item that they were going to sell, I pursued it immediately

within a short time of hearing it was available.  Literally

getting his email while I was still in bed, and ordering before

I got up to shower.  When they called to tell me it was shipping,

I actually was going to tell them not to worry about rushing

it, but the phone call was too short.



I know you didn't intend to imply anything big with the note

Michael, but I figured it doesn't hurt to make the statement

anyway.  Sadly, I have to buy most things these days, just

like everyone else.  It sucks, too, because I have a purchase

I want to make that is pretty sizeable ($6-8,0000+)...and man,

it would be cool if I could get a break on that.

The stock wheel that comes in the kit causes the valve stem to hit or almost hit the fork with the valve cap on, funny when I asked Vans they said just leave the valve cap off. lol...Dutch fix! I monted my wheel before the word came out about swapping it at Matco. I bent the valve stem but am still not comfy leaving it that way. I hated the thought of spending so much for a new wheel but I was going to do it anyhow. It's good news they will take the one half back and fix it for $60, plus the axel. There for a little while I thought I was just about over the nickel and dime portion of the build...but then I'm sending in my paint order today..let's see...Mortgage and bills or paint...mortgage and bills or paint...what's guy to do...PAINT!!!

For the new builders....



It's an old topic that used to get some attention. I don't think

it affects MOST people too bad, but, here's the story to the best

that I know it....



Van's buys a certain wheel that WE use as our front wheel, but other

RV's use as one of their mains.  That wheel works fine for them, and

Van's only wants to stock one model of 5" wheel.  So, we get what

they use.  The problem is, there have been some people who have

had the valve stem actually TOUCH the fork, because the way the wheel

is made, the valve stem sticks out too far with Van's standard

wheel.  Some people just leave the valve cap off.  Some people

(like me) leave the cap on and it wasn't a big problem...it was real

close, but never hit the fork.  Simply judging by how few times it

comes up on the forum, and assuming that 90% of the builders are

not swapping wheels (because like you, they probably didn't even

know about it, and just built the plane), my guess is that the

problem is not overwhelmingly common.  There may be lots of people

it affects, but probably not a majority, or we'd hear more.



But, it is indeed something that if you just build it, and don't

question it, you aren't doing "the best you can" to get things

perfect.  To do that, you would want to use the proper wheel.

And, after hearing of some complaints early on, Matco decided to

offer these wheel exchanges inexpensively, so that builders could

use the proper wheel.  I don't quite understand why the wheel

has to go back to them once it's been mounted, but you only

would need to replace 1/2 of the wheel because only 1/2 has

the valve stem hole.



So if you are not to the front wheel install portion yet,

it is probably worth looking into either NOT buying the wheel

from Van's, but buying the proper one direct....or, as soon

as you get your brand new nosewheel, call Matco and get them to

swap the half out.



Luckily for me, I was in the group of earlier builders that

really had no issue other than the clearance was minimal.

The fork builds up a lot of dirt and grime, and you'd easily

be able to see marks if the valve cap/stem were rubbing the

fork in use.  I've never seen any of that on mine.



So, it may not be a major worry, and if you already built it

and it doesn't hit, you have nothing to fear. (Besides that,

when/if you use Matco's new Axle, you'll get more clearance

on that side if you install the axle in the orientation I did).

If you haven't built that part yet, then if it were me, I'd

play it safe and just use the best wheel for the plane...the

one they're suggesting.

I went through this also with Matco when I first found out about it and

did the wheel swap.  Matco's rationale behind it is:

- if you haven't mounted the tire then the wheel is in new condition and

they'll swap it for very little $.

- if you've already mounted the tire then the wheel is assumed to be in

used condition.  In that case you have 2 options: 1) send in the wheel

half and have them "fix" it (or exchange it, not sure which), or 2) buy

the new wheel and sell your old one.



In my mind this is just like the axle deal - it's an inexpensive

permanent solution to what is best described as Van's low cost "good

enough" solution.  The wheel swap reorients the valve stem to give you

appropriate clearance.  Having 1/8" with the valve stem cap off just

didn't do it for me...  I ordered the axle assembly (also on the wait

list) for the same reason.  The Van's solution works (aluminum spacers,

not the stainless spacers) but clearly isn't the best.  I didn't make

any mods to prevent the spacers from rotating but haven't seen any

issues yet.  The Matco replacement assembly is inexpensive in airplane

dollars and is probably far cheaper than new bearings, a new front fork,

or whatever else might give it up because the preload might not be right

over time.

Oh yeah...holding my breath, actually no problems but it's a daily changing world. But in future messages can we not use "bailout". Seems like a bad word on an aviation forum!!

I totally agree Bob,



I will bet any amount of money as close as that stem is to the fork, centrifugal force will indeed cause it to scrape and rub on the fork. I was planning to buy the whole new rim, I just like the fact I can save half the price by sending in the rim for a fix. I wonder if my hangar association will mind my RV on blocks for a few weeks...I can hear the "There goes the neighborhood" remarks now.

I have the original tube and it is close but works.  

What Matco has told me is that the stock tube is hard to find if you were to have a flat without ordering one.  

That might be a good reason to upgrade.

permanent solution to what is best described as Van's low cost "good

enough" solution.  The wheel swap reorients the valve stem to give you

appropriate clearance.   Having 1/8" with the valve stem cap off just

didn't do it for me...  I ordered the axle assembly (also on the wait

list) for the same reason.  The Van's solution works (aluminum spacers,

not the stainless spacers) but clearly isn't the best.  I didn't make

any mods to prevent the spacers from rotating but haven't seen any

issues yet.  The Matco replacement assembly is inexpensive in airplane

dollars and is probably far cheaper than new bearings, a new front fork,

or whatever else might give it up because the preload might not be right

over time.

The problem is still here. I have a new kit and after putting the wheel together noticed that the valve stem was rubbing when the cap was installed. Always something!  Dan

 For the new builders....

 

 It's an old topic that used to get some attention. I don't think

 it affects MOST people too bad C but C here's the story to the best

 that I know it...

 

 Van's buys a certain wheel that WE use as our front wheel C but other

 RV's use as one of their mains. That wheel works fine for them C and

 Van's only wants to stock one model of 5" wheel. So C we get what

 they use. The problem is C there have been some people who have

 had the valve stem actually TOUCH the fork C because the way the wheel

 is made C the valve stem sticks out too far with Van's standard

 wheel. Some people just leave the valve cap off. Some people

 (like me) leave the cap on and it wasn't a big problem...it was real

 close C but never hit the fork. Simply judging by how few times it

 comes up on the forum C and assuming that 90% of the builders are

 not swapping wheels (because like you C they probably didn't even

 know about it C and just built the plane) C my guess is that the

 problem is not overwhelmingly common. There may be lots of people

 it affects C but probably not a majority C or we'd hear more.

 

 But C it is indeed something that if you just build it C and don't

 question it C you aren't doing "the best you can" to get things

 perfect. To do that C you would want to use the proper wheel.

 And C after hearing of some complaints early on C Matco decided to

 offer these wheel exchanges inexpensively C so that builders could

 use the proper wheel. I don't quite understand why the wheel

 has to go back to them once it's been mounted C but you only

 would need to replace 1/2 of the wheel because only 1/2 has

 the valve stem hole.

 

 So if you are not to the front wheel install portion yet C

 it is probably worth looking into either NOT buying the wheel

 from Van's C but buying the proper one direct....or C as soon

 as you get your brand new nosewheel C call Matco and get them to

 swap the half out.

 

 Luckily for me C I was in the group of earlier builders that

 really had no issue other than the clearance was minimal.

 The fork builds up a lot of dirt and grime C and you'd easily

 be able to see marks if the valve cap/stem were rubbing the

 fork in use. I've never seen any of that on mine.

 

 So C it may not be a major worry C and if you already built it

 and it doesn't hit C you have nothing to fear. (Besides that C

 when/if you use Matco's new Axle C you'll get more clearance

 on that side if you install the axle in the orientation I did).

 If you haven't built that part yet C then if it were me C I'd

 play it safe and just use the best wheel for the plane...the

 one they're suggesting.

I know what Bob means, with it looking very close, it didn't give

warm fuzzies.  I did leave mine in the beginning though, and

even with a small gap, (and it was pretty small) I never had

any scraping at all.  It was less than 1/8" probably for sure

before the axle upgrade I just did.  430+ hours without

a scrape and I can feel halfway comfortable that if you can

at least have near 1/8" gap, you probably have no worries.

If you already have a tire mounted, and the gap is there but

small, you may just want to get the new Axle and see how

that fixes the gap. It will add more, for sure.  But, NONE

of this is to try to discourage someone from buying the "right"

wheel.  I really think Bob did the best thing by swapping

his wheel for the proper one.  For the long term, that's

the best solution.  I just think if you end up with 1/8",

you're not likely to have problems.

 I totally agree Bob,

 

 I will bet any amount of money as close as that stem is to the fork,

 centrifugal force will indeed cause it to scrape and rub on the fork.

 I was planning to buy the whole new rim, I just like the fact I can

 save half the price by sending in the rim for a fix. I wonder if my

 hangar association will mind my RV on blocks for a few weeks...I can

 hear the "There goes the neighborhood" remarks now.

Yep you're right.  Didn't mean anything like what you were thinking below and I expected you paid for it and probably had one coming before Scotts post.  Just saying that your prolific documentation nature entitles you to get things ahead the rest of us and it wouldn't be a surprise if Matco made a point to get yours out ASAP.  Perk of the job as it were.

I did the same as Bob mentioned a couple years ago.  I brought the Van's rim with me to OSH and stopped by the Matco booth.  With the free shipping and discount offered during Airventure, I think I paid like $18 for the correct wheel.



  I'm all for lowering parts count to cut costs but some of these things are just silly.  Granted Van's can point to the fact that no one has had a problem with a deflated nose wheel due to this but it doesn't make it right either.
