Motor cover sealant after bearing swap


Recommended Posts

What do you guys use as sealant when re-installing the motor cover after a bearing swap?

Anyone know what they use in the factories?

I don't have a bearing swap imminent but have always wondered this and want to be prepared for the future.

The factory sealant is a very thin silicone-based product, sorry I don't know how to buy it.

I've always been wary of putting adhesives on the motor covers, since it's already such a pain to remove them without too much poking and warping. So I use a thin layer of sticky non-curing thread sealant on mine.

Yeah something like that, what do you think about the idea putting a small layer of silicone on the outside instead once assembled? That way silicone can be removed before disassembly.

Sounds messy :D

The motor cover fits the rim tightly, there's no large opening where water could enter... and rotation of the rim will fling water out and away from that joint anyhow. 

Assuming you're not immersing the EUC in water while stationary (which would destroy other things!), I don't think it matters much.

I used a thin layer of clear 100% silicone, using pipe thread compound would be a mistake since it's not waterproof and is only  impermeable under compression between threads. The thin layer of silicone is also easily separated if you need to get back in there.

Actually, that's what I did on my S22.

So far, the silicone is staying on.

I didn't want sealed it from the inside mainly because I wanted the air gap to be unaffected by the sealant.

I removed and cleaned up all the old sealant before closing the covers.

I also put a dap of silicone over each bolt hole.
