Posted: Wed Jan 12, 2011 7:37 pm Post subject: Mounting Main Wheel Question

In starting to mount my main wheels this evening, it became quickly apparent

that there was an issue with the cotter pin and the tire valve.    There is

almost no clearance between the valve cover and the axel nut.  



 



A side note, I really like the extensions that Tim had made for the

community.  Although I've had them for a while, I am extremely appreciative

of what Tim did for the community and probably can't express my thanks often

enough.



 



Back on topic, I was curious as to how others dealt with this.   I could

crimp the end a little tighter so that the pin sits a little lower.  Another

option would be to bend the top over to be more flat on top of the nut.  I'm

not sure how AC43.13 handle the lack of clearance issue.  



 



Comments?



 



Thanks,

Hence the Matco solution. Basically Vans will tell you to remove the valve 

cover and it will be fine, that is what they did with the demo plane.

I ended up paying $60 and sent my wheels back to Matco , they sent me the 

correct setup that allows the clearance you need. If it was untouched MAtco 

was replacing the wheels for $20.

I think you are talking about the nose wheel and Bob is talking about the mains. Not sure it is the same issue.

I think he's talking a different problem...the mains.   I haven't had a big issue with the mains.  I got some big cotter pins that don't stick out a lot of excess and when I bend the ears over it clears fine.  Sure, it's close sometimes, but it always clears.  You want to buy 100 of the right size cotter pins, because you throw them away every tire dismount.  I think if I remember right, my original ones were slightly longer and I snipped the tips.  The ones I use now are just about perfect.  They are a pain to install, cuz you have to arch them a little as you install them, and then straighten them out to get them through the far hole.  My worry has been that if the ears rotate, they could scrape the seal cover ring but that's not happened so far.

So unless you have a different clearance than me, Bob, I think it should be workable.  Thanks for the comment on the extensions....haven't heard of any breaking and there are over 160 sets out there so we must be at least doing better than stock.

good point! It is a different issue

 forget Matco solution, but “Basically Vans will tell you to remove the  valve cover and it will be fine, that is what they did with the demo plane.”  stays.

 I did go out and looked and there is minimal clearance, but should not be  an issue, especially if the valve cover is removed.

Tim hit the nail on the head.



Tim do you recall the part number of the pin that worked better for you?



Thanks!



Bob

The 10 needs the Matco axle. Those stainless  sleeves eventualy turn and score the fork. You might as well get the full matco  solution when you change the axle. I saw a 10 in Phoenix which some A&P had  returned to service where the nose wheel wobbled 15 degrees each side of  vertical.

Kind of difficult to change the main wheel axle to Matco.    



The nose wheel on the other hand, the Matco axle works great.



Just giving you a hard time.  I've been guilty of reading too fast and coming to the wrong conclusion too.



I also noticed what happened to my two photos that were pasted in my email and how the forum renamed them to something with an extension that most browsers won't recognize.   Tim was spot on, so I probably won't take the time to upload them again.

I changed tubes to the 90 degree stems, much easier to fill and no  

conflict with the nut or axle.

I can't find reliable info in my old pile of stuff. I'll

have to try to find out when I am at the hangar and actually

doing the job again.  I'm confused more now because I know

I've bought over 600 of the -362's...maybe when we did

the extensions?



MS24665-362  1/8" x 2-1/2



But when I read the plans, I see that Van's specs these:



MS24665-360  1/8" x 2



..which are actually shorter.  So maybe they fixed the p/n

already? or maybe it was just me.



Either way, just install what you have and know the p/n, and

measure it, and then see if it needs shorter and if so,

order a few to try, and if they work better, order a pile.

Wish I had better for-sure info....so don't trust the above

too much.
