I took my fan out to replace seals, and looked in govoner and the walls were coated in the worst black stuff, about an 1/8 inch thick, poped off crankcase cover and in motor too, how would i go about cleaning it out? what cause it? If i drained out the oil (changed oil 1 month ago, then again about same time last year)and fill it up will diesel and run it a while? or do they make stuff for this? also, maby some of the oil lines are getting cloged up cause my oil pressure has been going down. about 1 month ago, it ran med to high, now it runs a little below med. would the diesel, or what ever else fix this?
Thanks for any help

My humble opinion is that that crud has been there and building for decades. I agree with clooney on the removal. Take my popper, it looked like that when I did a head job on it. I put her back together and am using it. I do use detergent oil. When I started, it would blacken almost immediately, but has started looking better longer after about 50 to 75 hours. On yours, I would as a minimum get my hand down there and get what I could off the oil screen. Button it up for a couple of weeks and see if it bothers you then. I havn't thought about mine for a long time until you mentioned. Any way you go don't forget to enjoy it :) .

Joe, that stuff is caked oil mixed with dirt & carbon. Probably from the use of non-detergent oil is it's early days or the use of tractor fuel.
~You can try the diesel fuel or other solvents but I think you will find that nothing short of hand scraping & elbow grease will touch it. Places like the governor & upper crankcase area receive their oil by spray & oil spinning from the gears, so just cranking won't even get the solvent to those areas.
~You want to be careful if just using solvents to loosen those deposits, if they are just loosened & not removed you will have oil problems & plugged oil returns far into the future. ~I think you will find that even using a scraper, putty knives, stiff brushes & anything else that will fit is a lot of work & even then takes some type of solvent [I use kerosene with a little diesel mixed in] in a garden sprayer to keep it wet while working. ~When you finally get it fairly clean inside you will probably find it then starts to burn some oil due to loosening of the crud around the pistons & rings. The oil seal behind the flywheel will probably start leaking also, [if it isn't already due to a plugged oil return hole]
~There is no way to tell exactly why your oil pressure is lower, it could be from the oil thinning more due to the higher summer ambient heat, oil dilution from gasoline in the crankcase, bearings wearing, oil filter cover being over-tightened & warping the filter can top. Or with all that crud, a good possibility of the oil pump intake screen being partially plugged with that crud & restricting the oil flow into the pump, [reach down in there & feel around the pump screen & see if there is a build up of crud around the screen [I�ll bet there is]. ~You kind of got Pandora�s Box there, if you leave the crud it will bother you, & new detergent oil will dissolve enough of that to plague you with plugged filters, plugged oil returns & plugged oil pump intake screen. If you decide to remove it you will have a job cut out for you.
~ I�ve done plenty of those crud removal tractors in my life & haven�t found a short cut that works worth a darn short of removing all the covers [including the 1st reduction] & [governor] & scraping the crud out with a scraper & hard work. It is a dirty, dirty job that will leave you smelling like diesel, & covered in crud up to your shoulders, & your wife will not be happy with you for about 3 days�.

Beautifully put Steve!

We can learn a lot about taking care of ourselves by reading the tractor service manual!

Bob,

Thanks. I like that idea. Replace the Physicians Desk Reference with a JD manual!

Now you know what I do and what I worry about when I wake up in the middle of the night and can't get back to sleep.

Joe,

I posted a thing in the Mickey Mouse topic above about a junk yard Ford V 8 I had which was probably far worse than your '46 B. The parts washer and lots of oil changes at first worked well. The tear down to clean it approach reminds me too much of the service, and cleaning latrines with tooth brushes. Besides that personal problem on my part, the odds go way up that you're going to break something during the tear down on an old engine. Sounds like you're working the tractor this summer. Big tear down projects are best left for the winter. I always get in a hurry to get something back together when I have to use it again soon, and Murphy's law takes effect.
