A thrust washer by any other name?

[Garry_Coates]

My 1995 Honda St1100 ABS/TCS has lost its original rear wheel thrust washer. Probably wore through and fell out during wheel servicing. The part number is 42616-MT3-000. ST1100s from 1996 have part number 42616-MAJ-G20. Neither part has dimensions provided. The only one I can get for a long trip this week is 42616-MAJ-G20 which has been installed. It is making a slight "growling" noise when I spin the wheel but fine when riding.

Can anybody elucidate based on prior experience?

Regards

IIRC '90 ~ `95 had a steel washer, '96 onward a nylon one...
The noise could have various sources, I'd start with checking the hub dampers and wheel bearings though...

Hi ST1100Y. New dampers and alum inserts just installed. Bearings where fine before instal.

Both thrust washers are listed as in stock at Fowlers - one of the biggest suppliers here in the Uk.

Not much use to you in Oz, but maybe an indication of availability.

Hi John,
no steel ones in Australia so it is on back order...

For future reference I suggest that those that have spares could measure the :
1. Inner diameter
2. Outer diameter
3. Thickness

That way we could compare dimensions

that spacer and all the stuff between them move together. With rear wheel bearings one side has to be installed first, don't remember which side.

This one (42616-MAJ-G20) is the same one used for my Valkyries.
Ronayers.com is showing these (42616-MT3-000) as available.

Small bearing is fitted first (brake disk side). The nylon thrust washer is nominally 1mm thick. The GL1500 and ST1100 washers are interchangeable.
Looks to be available from Japan. https://www.ebay.co.uk/itm/304776391518

I have only seen plastic and brass thrust washer. I think they are interchangeable.

Steel and nylon, identical/interchangable; have not heard of a brass version. As to the growling, if the new bearings were installed incorrectly (side-loaded) that’s one possible cause; there are others. FWIW
