Rebuild Question

Danny Prosser · Feb 2, 2017

What do you guys use when rebuilding an engine for lubrication? I remember my dad used to use white grease on the bearings and cam lobes and motor oil in the cylinders. I'm starting to get everything ready so when the shop gets my crank and rods done I can order a rebuild kit and get started. Also how do you prime the oil pump or do you? This is on the MF 230 Diesel. Thanks for your help.

Assembly lube. Comes in a little red bottle.

I have seen everything (and used) from mice to monkeys!!! STP and as RR said special engine assembly oils Some kits come with an oil. The camshaft I just put in came with a bag of grease. good luck

I've used a product called Sta lube engine assembly lube. I like using a grease type lube on a lot of things because with plain oil it runs off if you don't get around to first start all that soon.

I bought assembly lube at NAPA, in a big white squeeze tube.

I have done a few engines now and have used white gease on the bearings and dipped the piston/ring/rod assy in oio before I put on the ring compressor. So far so good for me. The white grease was advice from the guy who does my machining.

As others, said use assembly lube.

Then, before startup, a converted clean, new, common plastic garden sprayer with a couple of quarts of engine oil in it will allow you to fill the oil galleries, prime the oilpump, and lube all the bearings before.

Lubriplate 105 is pretty good, and when you get done with your rebuild you can use it for a lot of other general-purpose lubrication needs!

The must sell it in a pre-dirtied tube. Mine looks exactly like that pic!

I use assembly lube on the camshaft and lifters only. Mains and rods get fresh clean engine oil. I like 30 wt valvoline if an older motor. Late models with tight clearance, use mfr recommended. I dunk the assembled piston, rings and rod in a can of new oil, let me soak for a few minutes, then load em in the ring compressor and install em. On the rod bolts, slip a length of rubber fuel line over each rod bolts, maybe ten inches long. This helps line the rod up so you do not nick the crankshaft. Keep the bearing dry if you are going to plasti-gage the clearance on the bearings. Lube them after gauging. Mains the same way. I pre prime the oil pump off the motor with oil before installing. Then prime the motor before starting. Keep everything clean!!!!! Check you end gaps on the rings before hand also.

I use an assembly lube consisting of one bottle of STP and one quart 30W engine oil. Use it on everything but the pistons and rings which get straight 30W oil. I have an oil tank made up to fill the oil galleys using air pressure. I always use break in oil for the first 100 hours to help rings seat.

I was taught to avoid white grease on the crank journals is it could plug the oil passages and restrict flow to the bearings. We used a mix of STP and engine oil; 5 parts oil to one part STP. Flows but still tacky.
