Starter oil seal

[mxvet57]

Last year the starter was giving me problems and after 200,000+ miles the brushes needed replacing. Took the starter apart and not only the brushes were gone there was oil all over the brushes and comutater. There is a oil seal behind the brush plate and Yamaha dose not sell that part. Tried to cross referance the number on the seal but can't find a match.

My question is has anyone replace the seal and where did you get it from and what was the seal number.

Lots of starters seem to need replaced at that distance. Read here

Time to drag this old post into today. I'm getting ready to rebuild a starter and will want to replace this seal. I've found a few rebuild threads and all have looked for the seal, but no one has posted up a number to get one somewhere. Has no one found a suitable seal? Please post up if you have, otherwise I'll have to wear out some shoe leather (motorcycle boot leather in my case) to find one.

All you need to know is the type of service (Nitrile, Viton, Silicone, EPDM) based on fluids (oil, water etc) and temperature.

Useful guide here for O ring material selection.

Then you just plug in cross-section and Inside Diameter.

I use Simply Bearings in the UK but I am sure there are similar suppliers available to you.

The numbers on the seal are the size of the seal in MM. Any decent bearing house will be able to source the seal. I've replaced a few of them.
