I probably would not be using WLG for a motor bearing, for that I’d make sure Id make sure I’m using a grease that has motor bearings listed among its applications.

Don’t want to buy a new alternator?Consider installing a remanufactured alternator with a warranty. It’s a reliable and cost-effective alternative if you’re tight on budget.

If it fails, it can disrupt the car’s electric system, leading to electrical power shortages that compromise driving safety. A faulty bearing can also damage the alternator, serpentine belt, and other components run by it, resulting in costly repairs.

This small yet crucial component supports the alternator’s rotor shaft and allows the rotor to spin with minimal resistance.

As for overpacking itself, I’m sure excess grease will work its way out pretty quickly so I don’t think that will do any harm for the bearing, but excess grease being flung around your motor is probably not good. Will attract dust and junk for sure.

But the few times I’ve tried to service motor bearings ( not in Esk8, just in general ) they seemed a lot more picky about it, and about everything else.

Alternator bearings typically last between 100,000 and 150,000 kilometers, depending on your driving habits and environmental conditions. However, their lifespan can shorten due to:

I used the same grease in my motors, but with a dab or two of red’s speed grease mixed in to it. That way it had the same thick consistency as the grease I removed (thick) but had less rolling resistance than just the WL grease alone.
