what grease to use on crank seals?

[THE GRIM RIPPER]

I always have heard to use lube on seals when building a motor, any motor.... So I always have. I use a touch of thick gear oil or assembly lube (something that will hang around in case I dont fire the motor right away) But then again, I used to use anti sieze on my flywheel untill Loco brought up a good piont about that putting more stress on the woodruff key. Which is unrelated but what I'm sayin is untill I see a valid reason not to use a little lube on the seals, Im gonna do it, cuz It makes sence to me.

Chatroom son? You dont remember the convo? Told me no go on the anti-seize for the crank / flywheel

I would just use some premix oil. I woudlnt run the risk of getting grease in the berrings. Watch that bearring grease get hot and turn to plastic.

grease wont hurt anything. Your banshee manual tells you to pack the whole inner lip of the seal with grease.

ive never put anything on any seal in any motor ive ever put together.. and thats quite a few motors. this is the first ive heard of this. how would they burn up?

im not buying it.

 

 

Same here. Seems like a good idea, though.

i like to use a lightweight grease. like assebly lube, or some special stuff i have. but make sure it's compatible with the premix oil definately, the seal soaks up the oil, but if you change iol types that aren't compatible, they could harden or deteriorate after a while. you can install them dry, but it will shorten the life of the seal a little, which is ok if you rebuild regularly, but not if you want it to go 10 years on this build.i just changed a seal today that was put on dry and it only made it about 2 weeks, but that's a higher pressure aplication, and it was just starting to leak. when in doubt, just use the oil you'll be running. :wink:
