Att: Larry Cottrell- I think I'm misunderstanding something important. Did you break the "A" frame behind the seat, or the fitting at the lower end of the landing gear leg? I need to check mine- old age.

The fitting at the end of the gear leg.

On my old Firestar, the tube thickness of the axle fittings appears to measure .0625. This is approximate, due to light rust, paint, etc. 

    Larry- can you take the calipers to your broken one? John H. measured .0650. 

  My axles also seem to have RTV in the socket- Is this standard practice?

With the paint and other stuff on mine the measurement comes  out to .067, so I would venture that .065 would be correct.

Donnie at Kolb sent me a note, the "beefed up" parts have .120 wall thickness.

Larry- .065 should be the new one. Is that the one you broke? I measured mine again, and mine is definately thinner than that.

Thanks, Jim. That definately makes mine the older parts.

The "beefed up" parts are fabricated with .120 wall and came out in 2001.  The new parts were shipped with kits after this time.



The parts were changed due to reports of cracked and/or broken parts in service.  The new part has no reports of problems per TNK.



It is a direct replacement part and they cost $47.50 each + S&H.  I ordered a pair today.



Fly safe,



Jim

The pic at this link is the OLD part -

I received my new gear leg/axle mount fittings today.  They are for a FSII



I need some advice.



The old part is installed and you can see it below.







The new part is not drilled.











You can see how much thicker the tube is on the new part.  



I am not sure how I will relocate the drilled holes on the new part to match the  gear leg.  I have some ideas, but I have learned that it probably has been done many times before and I can skip some frustration by asking.  

Any tips would be appreciated.



Thanks.



Jim

  Jim, You must have forgot the photo.  Yes, I have a suggestion, but I want to see the photo first.

Mike:



Which picture do you need?  The painted white is on my plane, the bare metal is the new part.  I see them on the page, they are coming in via a html  placemark.



I can post them if they do not show up for you.

Yeah, Jim, post them some other way, 'cause I don't see anything but typing.  You can send (both of) them by way of the email I sent you backcopy.  Then call me so I can help you locate the drill holes in the new fittting.

Do you know what a rivet locator is?  It is used to locate a hole in the top

skin when laid over a hole in a lower surface...   how to make one...  take

a 8 inch piece of sheet metal  and fold it in half.  Then drill a hole

through the ends where they overlap...  place a rivet through the lower

piece and insert the rivet in the under lying hole, then putting the piece

of skin you want to locate the hole in, between the folded over halves of

the locator,   the hole in the top of the locator will locate the hole in

the skin.

With that mental picture  in mind,,,,   take a piece of sheet metal, and

clamp it to the leg a few inches above the axel fitting using a screw clamp,

or two to keep it from moving....  drill the sheet metal from the opposite

side of the gear leg through the existing hole.  This will locate the

hole...  then pull the sheet metal far enough from the leg to slide the axel

fitting on,, make sure you don't move the locator,   when the axel fitting

is properly aligned,, the hole in the piece of sheet metal will locate the

hole in the axel fitting.

Ok I am going one step further after sleeping on this…    

   

In order that you don’t increase the size of hole in the gear leg,  make a snug fitting bushing and slide it in the gear leg hole….  Now when you drill the sheet metal to mark the hole location in the gear socket…  use the largest drill that will fit inside the bushing, using it as a guide.   

   

Slide  the axel fitting on the leg and align the fitting and drill with the smaller size drill.. after drilling you will be able to check the alignment by putting the drill bit through the hole in the axel fitting and  into the bushing..   if the alignment  is ok then go ahead and drill it to the proper size,,, if it was off a bit,,, then file the hole in the axel fitting to correct the alignment,,,  then drill through to the other side of the axel fitting, then from the other side open it up to the correct size, remove the bushing, and continue drilling through the first hole to correct any offset.    

   

You may have to read a bit between the lines….  But this will give you a trial fit and a chance to correct it before drilling to the full size.

Boyd:



I have one of those hole locater devices you describe.  I get the idea of using the strap on the outside.



I was looking at the part and I am thinking I may be able to set up the old with the new and get the position located OK and put it in my drill vise and put the hole through both sides.  If the alignment is off  with the existing hole on the gear leg I can clamp it in place and drill through the next larger hole.



I would not even be messing with this if Larry had not broken his.  But, if I can minimize the opportunity to bend my plane, it is a good thing.  Besides, it is still cold here and I cant fly it anyway.



I have some handy tools to locate the centers of holes but they do not work here.  I have a phone call to make to another Kolber with a suggestion to consider too.



Thanks for the advise, I appreciate it very much.



Jim
