| I am rebuilding a Delco 10si alternator. The small needle bearing seems to be in good shape and I see no need to replace it but it should be cleaned and relubed. What grease would this take? I am pretty sure it should be a small amount so as to not have the excess get on the brushes and rings. |

Most motor and alternator manufactures will recommend a POLYREX grease.. That is to protect against fire / burning if too much is added....... That would be BEST... I cant say i have followed that recommendation all the time.... Any good Lithium based HIGH TEMP grease will work good... but the Polyrex is fire resistant. ------------- Like them all, but love the "B"s. |

I'm a huge fan of the grease made by the company 'Super Lube' that usually comes in small grey squeeze tube for any application like that. The company makes several different kinds/grades of grease, but the one you find most places is their NLG2 universal grease. Most auto stores around here carry it. 'Super Lube' is the worst/chintziest name in the world, and it's a little pricey, but it's excellent stuff. Thin enough for small needle bearing and high-speed applications, low kinematic viscosity so it gets around to all the parts in fine components, good for (comparatively) high temps, doesn't run too much, and lasts ages. We tested a lot of lubricants when we used to rebuild equipment for new crews at my previous job. This stuff was good for 90% of our applications - even better than several fancy German and Japanese lubes. The only stuff that came close being an excellent, universal grease for the majority of our applications was made by Chesterton for electric motor duty. Can't remember the specifics of it though - the 'Super Lube' stuff was pretty much as good, cost a fraction of the price, and could be bought up the road at Napa (the Chesterton stuff had to be brought in from England). The Super Lube company also makes a great spray lubricant with teflon.
