Oil Change

Anonymous-0 · Jan 14, 2009

My '44 H since it was bought was run with 30w non-degergent oil. I want to use 10w30 oil in it. Do all I gotta do is pull the oil pan off and dig the gunk out, or is there more steps I should take? For all of smart alecks out there,(you know who you are), I will put the pan back on. Thanks,

That wouldnt be a bad idea to clean the pan and the screen on the oil pump pick-up. Mite want to pull the tappet cover and clean up that area while the pan is off. good luck

I've never tried to find out the hard way, but the "old farmer's tale" is detergent oil [any modern motor oil] after non-detergent will cause leaky seals loose bearings, ect.

All I have ever done is change the oil and watch it close. May take 2 or 3 changes to clean it up but that is how I always do it. But on most of the tractors I have I also have no history on them so have no idea what oil was run in them

Thanks for the quick reply. everything else is fine (elecricts,fuel and all) but I just need to get cold weather freindly oil in it. Thanks Gene and Spiffy for reminding me of some the basics.

Old, I'm mostly worried about 60 yr old stuff being broke loose with detergent oil, and clogging oil passages somewhere else in the engine. Thanks

Look at it this way. If you do pull the pan and valve cover you might if your lucky clean out 50% of the old stuff. Most of that stuff is heavy and will fall into the pan any how and most of the rest gets stopped by the filter. So changing to a different detergent type oil will probably not hurt a thing as long as you change the filter and oil a couple times

I shouldn't worry about the rumors.

If you had soaked the motor in kerosene for a few weeks and then put in oil and run it, then maybe you'd get chunks, but that would happen with any type of oil.

Detergent oil doesn't really scrub like dish detergent. It is formulated to keep the crud that it does accumulate suspended so that it drains away with the oil rather than settling out and making sludge. It's a detergent, not a solvent.

It will pick up any soft soluble stuff at the surface and carry it to the filter. If only for that reason, you should probably do as Gene suggested and clean up the topside and pan first to get rid of as much as tht stuff as is practical, and then do your first and maybe even second oil and filter changes sooner than you might otherwise and see what it looks like. After that, just the normal change interval should do fine.

Beings the pan will be off, take apart and clean the oil pump pickup screen. With the oil filter canister off, blow out the passages in it and make sure the canister is clean inside. If it has not been done in a while, clean the crankcase breather element in the push rod cover.
