Avion Alignment Procedure - Service Bulletin 1978

[erk]

Found the procedure in a folder for the 1984 34v. Just figured I'd post in case someone needs it. I didn't see one posted but doesn't mean it isn't out there.

I've never seen the procedure laid out in this level of detail. I'll have to do some head-scratching on why the rear axles on a 34V are toed out, considering that dynamic rolling resistance of the tires typically wants to force the tow out even more.

When I did the alignment on our '88 30P 4 years ago, I put 5 of the 9 spacers on the front side of each center pivot point and 4 on the backside. According to my manual, each 1/8" thick spacer changed the toe 1/8" at the tires. Thus, the toe at the wheel was set at 1/8" toe-in in static position. When in motion, the roiling resistance of tires forces the toe to 0.

I have had good results on tire wear so far.

By the way, your procedure would be better placed in the Running Gear section. Can you move it there?

Hello Silverloaf, yes please move to where the correct location would be. I have not tried the procedure as of yet. I will probably at least check to see how close the tires are on my 34v and then decide if I need to or should.

I'm finding different docs as I go through what was left behind in the 34v. I know I have the full owners manual that almost appears to be untouched - other than the original owners name on the first page. I have that all scanned and can upload that also.

It would be great if one of the admins can save the file in the Documents section.
@KYAvion is an admin, right?

Done. Thank you!
