I have a main wheel off to fix a flat and greased the bearings while
I was at it. This is a 1977 Tiger. Have a question about the washers
and felt seals. The pictures on Bondline did not help. On the inner
part the bearing goes in then a washer 153-0400, felt seal, another
153-0400, and snapring just like my old Cherokee. The outer is
different. Seal retainer 153-01500 is C-shaped and holds the felt
ring. I assume felt faces outward and the metal surface of the washer
faces inward, then the 1530300 washer and snapring. Believe me I was
careful taking this apart but the parts were mixed, not at all like
in the parts manual.
Anybody care to share the correct reassembly order. PIctures in the
parts and service manuals are not in fine enough detail.

The felt faces inward and runs against the washer, which is slightly smaller
in diameter than the washer on the brake disc side.

Thank you Cliff. So the flat washer goes in against the bearing, then
the retainer with the felt ring, felt side first, then the snap ring,
if I understand you correctly. What exactly does the felt ring seal?
Just keep grease from slinging out?

I see more of these installed wrong than any other piece on the plane.
It's right up there with the nose gear stuff being installed wrong.
When installed correctly, the larger diameter 'washers', both inside
and outside, go on the inside of the wheel. If in doubt, make sure
they slide over the axle all the way past the step in the axle. If it
catches on the step on the axle, and won't go past it, it's wrong. Use
Shell 22 grease. The idea of the inner felt seal is that the inside
diameter of the felt seal rides on the portion of the axle just past
the step. It seals against the axle.
The outer washer has a slightly smaller outside diameter and a smaller
inside diameter. It should NOT slide over the step on the axle. The
idea here is that the outer washer provides the surface against which
the nut crushes the roller bearing against the step on the axle.
Properly adjusted, you'll get about 1 to 2 rotations out of the tire
when rotated firmly. Any looser than that and there will be no preload
on the bearing. By-the-way, that bearing is so over engineered for its
purpose that there is no way to describe it. The dust seal, that felt
in the cup, rotates with the wheel. The washer does not; it is crushed
between the inner bearing roller and the nut. Dust is kept from
bearing along the moving surface.
After packing the bearing with Shell 22, place the bearing in the race,
pack some grease in the area around the outside of the beaing, push the
washer in to squeeze out the excess grease, use some of that grease to
lightly coat the felt (yea, I know the instructions say to use 10
weight oil. That will just run all over the place.) and then install
(1) the other washer on the inside or (2) the 'c' shaped washer with
the dust seal, and the snap ring.
When tightening the nut remember: the grease will take up some of the
pre-load that will go away after the first landing. The distance
between the flats won't let you over tighten the bearing. Make it
snug, 1 to 2 rotations of the tire.
Good luck
