Full Engine Oil Seal Kit

For all years & models of TY250 Twinshock

Although please select your model above as the 1974 TY250A (#434) uses a different crank o-ring.

OEM Yamaha & Aftermarket parts

Consists of-

Crankseal Left - OEM

Crankseal Right - OEM

Right (Primary Drive) Side Crank O-ring

Gearchange Oil Seal - OEM

Kickstart Shaft Oil Seal - Aftermarket

Clutch Arm Oil Seal- Aftermarket

We use the OEM crank seals because they need to have double springs - 1 inside, 1 outside

The 2 springs are needed to form the seal

DON'T Fit single spring seals, waste of time, money and effort, most pattern ones are single spring

Both these oil seals have castellations on the inside faces to help with bearing clearance so when fitting the green side should be seen from the outside of the crankcase.

TY250 crankseal fitting

^This is what you see from the outside^

Including the all important o-ring that everybody misses out and wonders why the bike doesn't run well!!!

We also use the OEM Gearchange seal as the aftermarket ones are too thick so you can't get the washer & clip on the shaft
