Hi All,
I have pulled my rear end for inspection and to replace a leaking push rod
seal on the tranny. I have a few questions for y'all:
- There was a fair bit of oil (maybe a couple of tablespoons) in the Ujoint
boot and I am suspecting that oil is leaking from the output shaft
(layshaft) seal. Is it possible for oil to migrate past the carrier
bearing/ujoint? I don't think there is a seal in rear housing so I know oil
can move up the swing arm but could it be the cause of the oil in the boot?
- Since I have access to the shift return spring I intend on replacing it.
Assuming that I have the tranny in neutral is there anything that I need to
look out for when I pull the pin that holds the return spring? The 4 Speeds
are nice because they have a little cover plate for the return spring.
- The shaft (mentioned above) comes out the end of the tranny and it looks
like it is leaking a bit too. I was looking in the parts manual and there
was no indication of a seal. Is there one?
I think it has been about three years since I have looked at the rear end.
It is impressive to me to see everything so solid and in good condition. I
can understand how these bikes can go 100,000+ miles.
Thanks for the input...Ian
