Looking over my third-hand 601XL kit I see that the front bungee cord pin

6G2-2 rubs on the gear leg 6G1-1. Looking at the stack-up of dimensions the

tolerances are very tight. The 5/8th inch (15.8mm) pin passes through a hole

whose center is 25mm from the firewall (see 6B8-7). So the forward edge of

the pin is 25 + 15.8/2 = 32.9mm from the firewall. The 2 inch gear leg

(radius = 25.4mm) passes through a hole in 6B7-1 that is 60mm from the

firewall bend radius. The dimensions in the bottom bearing 6G2-1 are

similar: the center of the 2 inch hole is 58mm from the rear edge of the

block. So the rear edge of the gear leg is at 60 - 25.4 or 34.6mm from the

firewall with some slop for the bend radius. 34.6 - 32.9 gives a clearance

of 1.7mm. And the bungee pulls these two pieces together, removing any slop.



Does the pin touch the leg on your plane? Is it acceptable to shift the

nylon bearing forward to create enough clearance (I've got to replace mine

due to other problems)?



I'll be asking Zenith the same question.

Craig,



The lower bungee pin 6G2-2 does not touch the gear tube on my XL.  I don't know what the clearance is, but I could put a piece of .025 between the two without any friction.

Mine, kit-built, has about 2mm clearance between 6G2-2 and 6G1-1..
