PRM oil seal

[dor]

I appear to have a very slight oil leak coming from the oil seal to the output shaft on a PRM 150.  There are four bolts which look as though they retain a piece with the oil seal, but the output shaft has a raised ridge around it, along with the shaft flange which would prevent the oil seal sliding off.  So, presumably the output shaft would have to be withdrawn from the gear box.

Has anyone got experience of changing this oil seal, and if so, do they have any tips or procedure to follow?

You have to split the gearcase to replace the oil seal and/or bearing.

Thanks.  I was hoping it might be a simpler job.

It’s barely leaking a drop a day at the moment, but I guess it will need doing sooner or later.

The little seal on the engagement lever is a pain, with its spring and ball bearing.
