Topic: Engine re-assembly question

[ZanVooden]

Alright so I'm getting ready to re-assemble my 750K8 engine here in the next couple of days (depending on when I get my last freaking valve spring, that I've been waiting on for 2 months now), and I was wondering whether or not I should use assembly lube on the gaskets as the engine goes back together, or just put them on clean and dry.

Just put them on clean and dry.

Speaking of assembly lube... Is it recommended to put moly assembly grease on certain parts like bearing shells, gears, etc. when assembling a CB750 motor? If so, which parts should you apply and which should you avoid.

Hmmm.  I kind assumed you could slather it all over everything that would normally be covered in oil, but I'd be interested to hear if that isn't the case...

I made the rookie mistake of using Molly lube on my cams on a Interceptor.

The molly lube they use on cars, contains graphite which in turn ruins the clutches. I'm still waiting for them to slip on me.....
 It's only been 40miles. $300 clutches here I come.

But when installing new parts such as cams and bearings its highly recommend that you use MOTORCYCLE specific assembly lube.
 When you just put normal motor oil on them, in just a few days, the oil runs right off.....just leaving a very thin layer of oil.

Now if you were to be putting the engine together in one or two days and starting her up, then by all means, use some good 10w-40 oil.

But learn from my mistake.

Best of luck

I used the really thick clear STP oil additive (I don't imagine small amounts will hurt the clutch) as it won't run off. Lube the pistons/cylinders and cam lobes. If you are doing a bottom end job with the crankshaft and such, lubricate the bearings. If you don't you could seize things up. Kick it over without gas in the bowls a good number of times to circulate your oil.

When I started it up I had no smoke. I really think kicking it over before starting it to circulate oil and scrape the cylinders helped a lot with this.

EDIT: I should say a VERY thin layer was used, not gobbing it on or anything.

 I use Red Line assembly lube. Never any problems.

I'm using Redline too.

I've heard some people recommend lubing the cylinders and others recommend not.

Thoughts?

I very, very lightly coat the cylinders with motor oil (more to stop rusting than anything else). The cylinder walls are basically dry.

Clean and dry new gaskets be very sure mating surfaces are clean.

Good Luck

the guy at total seal gave me some assembly oil for the rings and piston skirts. it's has consistency of light oil. i usually rub oil on the walls and right before start up i drop in about a teaspoon full so i know the walls have some coating. just makes start up a little smokey
