1980 DT80 Outer Crank Seal #1
Hey guys! Anyone know the part number for a 1983 DT80 outer crank seal? I'm having a hard time finding one that fits properly on the outer side of the crank bearing. This is under the left engine cover. Thanks!

Thanks! I just realized that I posted that is for a 1980. It is actually an 83. Do you think this will still work? I don't know if there was much engine change among the years.

I'm pretty sure those bikes are very similar from the 70's to the 80's.

Online parts lists can be challenging. Especially where Yamaha is apparently "sharing" parts lists over several years.

1983 was the "K" model. If you look at the link to the seal in my post it shows it fits DT80-H-J-K.

You also have the dimensions... so to be sure, measure.

That seal fits so many things my guess is just about any Yamaha dealer will have one on the shelf.

Good luck!

Thanks, guys! I just found one on eBay. The shipping from the other sites was a bit steep for such a small part!

eBay is one of the best places for these parts because a lot of sellers will do free shipping and usually only charge a bit more than those websites. Gotta love eBay!

Got all the parts yesterday and installed them all today. So grateful to finally have the oil leak solved. Now, all the other fine tuning and it should be ready to fire it up!
