I would like to repack the original wheel bearings of my 1976 Trillium
1300 and will need a new rear grease seal. Would anyone know the part no for the seal or specs (ID, OD, width) ?
A search of this site did come up with one hit and reference to a seal with Napa part no 17404, but looking at the specs for the seal, I don't think it would be the right one for this original spindle, as the ID was 1.75" and OD 2.565" which sound too large. I would expect the ID to be more like 1-1.25".
It would really help to have the right seals in hand before doing the job, because I hate running off in the middle of a job to find a part or tool when I'm all dirty and greasy.
My trailer should be due for a repacking as it was last done in 1998, although not a lot of miles since then according to the previous owner.
There have been a number of threads about the pros and cons of doing it yourself. I saw a wheel bearing being replaced on a 30+ ft Class A in a campground 2 wks ago by a road service and watched the tech carefully how he packed an inner bearing. He didn't pack it like what is recommended in the wheel repacking videos with a packing tool or in his greased packed palm and basicly rubbed grease on both sides of the bearing. Admittedly, in this class A, the major wheel lubrication was coming from the differential fluid line.
That told me I wasn't going to pay him to repack my bearings for $150 plus seal costs. I have repacked bicycle bearings so this kind of job isn't totally foreign.
