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.

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? Scott On Jun 2, 2007, at 6:24 PM, flyv35b wrote: > > > The outer is >> different. Seal retainer 153-01500 is C-shaped and holds the felt >> ring.

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 -----Original Message----- From: Scott Boyce Sent: Sat, 2 Jun 2007 6:58 pm Subject: Re: TeamGrumman-List: Tiger Wheels Thank you Cliff.
