Mk II driveshaft lube?

[frankd]

I've got my 89 in pieces--it's winter and a great time to do Preventative Maintenance. I pulled the shaft drive apart to grease the front spline. Is there any reason for me to pull the shaft out of the gearbox and lube the rear spline?? Or is the designed lube flow (from the gearbox) just fine and never given anybody a problem??

 

If I pull it apart, do I just take the snap ring off and slide the washer off?

The oil seal is bonded to the coupler. You'll ruin it removing.

 

If it were me I'd pull it apart and lube it. It's probably been 20 years. You'll need a new oil seal though.

Carl,

 

Do you have to have the seal ?

 

Do the MKI's not have this ?

As I recall the MKIs do not have it.

 

The MKIIs do, and I believe the 2nd gens do.

 

Based on the number of MKIs that have ruined splines I'd guess that the engineers at Yamaha decided they needed to keep dirt out, grease in, or both.
