Oil for repaired SH

Anonymous-0 · Apr 19, 2012

I have had oil pan off and all pistons out.All washed and cleaned with solvent. Head is off and cleaned valve train and parts of oil and gunk. The inside of block has been washed and cleaned with solvents . Push rod holes all cleaned and washed. Can I flush out oil pump to make sure it is clean?

Should I go with a detergent oil oil or go back to straight sae 30.

Oil up the cylinder walls and all the bearing surfaces. Otherwise they may rust.

Sure. Fill it up with assembly lube (not heavy grease!) when you are done. First, though, you may want to consider overhauling it. What was the oil pressure like before the teardown?

Use modern multi-weight detergent oil. The (bogus, IMHO) argument for non-detergent oil in old engines is that it might emulsify the crud but you've removed that.

No use a 15w40. It has a viscosity equal to a 30w, but you will also get the added 40w visc when things heat up in the engine.

If the engine is all cleaned out there's no point in making special effort to find and use non detergent oil.

Just use a good quality engine oil. Whatever you use in your car is just fine.

No, do not use the same oil as you use in your car. It does not have the additives that these old tractors need. Use a 15w-40 oil that is rated for use in a diesel engine.

On here and Red power 15-40 Rotella seems to be the trend now! I run SAE 30 Valvoline with a GOOD zinc additive,but am not opposed to running the 15-40 diesel oil.

Subject may need revisited since the additives are lower in the new diesel oils commonly sold at outlets. Diesel oil for just pre 2007 engines or some racing oils have the higher additives. Just can't buy them at every store.
Don't think its going to matter a whole lot if the correct weight detergent oil is used on the low RPM and spring pressure engines like the SH.
Lot of them have survived years with anykind of oil dumped in and infrequent changes.

I agree with that. Like I have said before,the BIGGEST thing is actually CHANGING the oil on a regular basis!

An oil change AND using a tube of grease on the chassis on a regular basis goes a long way !
