Tacho drive seal

<< < (2/2)

Bryanj:
Yes the tacho seal is in the kit and no the sprocket seal is not lipped, but then never seen one leak either! Have seen gearchange seal leak tho'---usually because of crud on the shaft, also if the pushrod seal is leaking it's usualy 'cos the pushrod has been broken by a loose chain

Tomb:
Thanks Brian, good point  ....is it the final drive shaft seal leaking?

I think I'm gonna have to do a real good degrease under the front sprocket cover and take the bike out for a spin to confirm which seal is leaking, I could do with the 550 clutch cover mod doing first, that way I could take it out for a spin without the sprocket cover fitted to watch for the first signs of oil leak.

I know the tacho seal is leaking, thats easy to see :D

Bryanj:
Just fitting the 550 cover does not work!!

You would need

Complete 550 clutch
550 primary gear
550 clutch cover
Modified crankcases as the clutch cover has a different gasket shape
550 rubber blanking plug instead of pushrod seal (now obsoleted!)
LH rear engine bracket

Or to put it another way DON'T BOTHER

Tomb:
I assumed I'd need the cover, clutch, and have to blank the old push rod hole.

I have all the parts needed (including the primary gear which I didn't know I'd need)

I wasn't aware that the crankcases would need modifying! Bugger!

Not worth the effort then.

I have a complete 550 parts bike so may just transplant the whole lump. Trouble is the 500 motor has been with me for so long I'm a bit fond of it (sentimental old tosser LOL)

Tomb:
Engine oil seal kit arrived today from Silvers,
