Looks like there are no OEM countershaft (sprocket) seals available. Any recommendations? I’ve seen several threads on here with the kit on the red card. Those don’t seem to be there anymore, although there are several other choices.
If anyone has recommendations for a tried and true kit, I’d rather make an informed choice than a shot in the dark…
Thanks!

This one?

OIL SEAL (35X62X6-371) for DT3 1972 1973 USA - order at CMSNL

It might still be available from Yamaha. If not, source a seal of these dimensions from a reputable bearings and seals supplier.

Hey Unc, thanks for your quick response! I’ll have to do a little digging to see if that’s the right one. Is there a listing by dimensions for the seals somewhere?
I would just as soon get a full kit if someone knows of a good one.

Sometimes the dimensions are shown alongside the part number within the parts list - if you've clicked on my link, you'll see them. Alternatively, you can search a part number on CMSNL, fleabay, Partzilla etc and, if there are photographs, the dimensions will be shown on the seal itself. Always view multiple listings, just to check that someone hasn't made an error in the listing. 

Here in the UK, a lot of people use a company called Simply Bearings, and you can input the dimensions of any seal to see if they can supply it.

Thanks for this info, will check it out in greater detail later today.

I have plenty of those if you can't find what you need.
All genuine Yamaha.
