Moly EP grease and engine assembly.

[Mr. Cuda]

I've just laid a crank into an engine I'm assembling. The grease I used is Coastal Industial Moly EP grease. When I was cleaning up, I noticed that the smell of the grease reminded me of that used for wheel bearings and such. When I read the fine print on the can, I noticed that it contains Lithium as well as molybdenum disulfide.

Now I'm a bit worried. Have I just made an expensive and stupid mistake or can I continue to use this as an assembly grease? I haven't assembled anything else that requires it yet just in case I'm in for a nasty shock.

Hard to say.

I always use clevite 77 engine assembly lube. I'd say what you've done is better than the "lubriplate" that alot of guys use.

I don't know if I'd worry about it if I were you or not. As long as you prime the engine properly prior to start up, the assembly lube is only required for a few seconds anyway.

If you've only got the crank and mains in, I'd dissasemble it and start again. Your not too far into it yet.

Don't want to see any of this down the line

You'll be fine, if not a little overkill. That's what we use if the engine isn't likely to be fired for 6 months or more. The lithium just has more staying power and the moly is just the extra lubing property.

Dont never use lithum grease for bearing assembly if the engine is going to sit for a month or longer before running! If you dont belive me get some and leave a little laying around It will get hard as hell! The best to use is STP engine treatment! It will stick with the bearing a long time with the critical first time start up and will not harden up too! I think that a bottle may cost you 2 bucks and have enough to assemble half dozen engines!

[lenweiler]

And that's why it's mixed with the moly.

STP engine treatment and 30 weight engine oil mixed 50x50 was used on my first engine rebuild. My friend and mentor suggested this stuff he refers to as snot, has proven satisfactory over the years and is another consideration for use.

Assembly Lube
TECHNICAL DATA
Red Line Assembly Lube is designed to be used as a lubricant to apply to potential wear surfaces before assembly in order to prevent metal contact upon startup before adequate lubrication is supplied.

Red Line Assembly Lube will mix with the oil and not plug filters. Red Line Assembly Lube can be used on all lubricated parts such as cams,followers, pistons, and bearings, and bolt threads. Use only a small amount on bearing and piston surfaces - too much can make it difficult to turn over the engine. Do not use on exhaust bolts or other high temperature bolts which require an anti-seize.
