Posted: Sat Dec 17, 2016 5:20 pm Post subject: Question on Lucas assembly lube and rod bearings |
|
|
I have read good things about the Lucas assembly lube and used it today when building my crankshaft. Plastigage and rod clearances are within spec. No tight spots when rotating the rods, but they do not swing freely. This stuff seams really thick. I pulled a cap and removed some of the Lucas and added 30 wt. much better. I them wiped off all the Lucas and coated with 30 wt. and now the rods swing like butter.
I believe the Lucas assembly lube would protect the bearings, but am concerned it may be too think to let the oil in. Thoughts?
Maybe this product would be best for the oil pump.
Thanks,
David |

I assume it is a thick goop? This is good for if the engine may not get started for a long time. It will protect all the surfaces and not dry or runoff. Way better than grease!
If the engine will NOT be sitting for a long time, or will be pressure lubed before starting, I prefer to use 90wt gear oil for this, and a lot of things, valve guides, pin bushings, ect. but keep it off the cylinders. The gear oil has slightly more EP additive and less detergent so it slightly more suited than engine oil, but engine oil will work fine too, 30 or 40 wt tends to stay put better. 90wt gear oil is actually not any thicker, they just rate gear oil at a lower temp.
While I may be conflicting my own advice here, I've lubed stuff with gear oil and even a year later it hasn't gone anywhere......seems to work great. i should just put some red dye in there, a bit of wintergreen oil, and re-label it as super assembly lube and make a killing |

Thanks Glen, yep pretty thick stuff. The motor will not sit for an extended period, just going slow on my first VW build. I will pick up some 90wt and proceed.

I've used the Redline assembly lube and also white lithium grease in the past. Neither is very thick and will "wash away" with the oil. Both work well to prime the oil pump too. |

I Use Sta-Lube.... Brand probably does not really matter as long as you spin up motor and insure you have oil pressure and have whetted all bearing surfaces before you put the fire to it...

We used to use gun Greace when I was a kid. I've used motor oil, stp, white Greace , moly with graphite, Ect. Hell I used to put Vaseline in the oil pump to prime it, why? Who knows, I hope I read that somewhere intelligent. I prefer redline moly but I have to order it and that sucks. _________________ Rides:

Lucas assembly lube is fine. I have used it in numerous instances. Assembly lube is supposed to be thick...dont worry about it. Once the engine builds oil pressure and oil makes its way to the bearings, the assembly lube will wash away. _________________ 1800 Type 4 Berrien 295

I used a small can of generic sewing machine oil because it had a convenient nozzle..
Seemed a bit thicker than engine oil and stickier. But then I had it running only a couple of days after throwing it together.

What's really nice about the Lucas assembly lube, is that it pretty much stays where you put it. Everything that I build is second to my real job, so sometimes there are weeks where I'll leave an engine sit half done. With the Lucas, there may be a few drips under a short block if left for weeks. When I was using redline, or before that, moly based sta-lube, I had to leave a drip pan under the case because of how much would run out. It never really instilled much confidence when firing a motor that had sat for months while the tin and carbs got sorted, how much protection was left there for the bearings when it was started?
Lately, I've been using the Torco MPZ. Webcam sent me a decent size tube with my last cam and I liked it, so I ordered more. It seems a bit thicker than the Lucas and really stays put.
