I'm in the process of a top end kit on a 2000 rancher 350 es. I was told by two different mechanics that the rancher were bad about getting dirt in the case and if you didn't tear the case apart to clean it the rebuild may not last long. The dirt was bad about entering from the pull start. This has me totally bummed out as What was supposed to be a easy top end kit has turned into a pain in the @$$. I'm just wanting some opinions here on past rancher rebuilds and pointers as to what i Should do. I never have been in a case before so it kinda scares me a bit. Lol.. The lower end looks clean looking down beside the rod but I realize that may not be the case. I even wonder if flushing the lower end would work? Hit me with what y'all think.......

i personally haven't torn into a rancher yet...but..what i can tell you though..there is no sinse in spliting the case...even if there was dirt inside the lower end...now...i would pull the motor.. < makes it easier to flush this way >..pull the front and back cover off < clutch cover > < pull starter case cover >...make sure you got new gaskets ready just in case you mess the ones on it up ....pull out the oil filter..the oil screen filter if it has one..pull the oil drain plug...and thorughly rinse the engine out with the engine degreaser..rinse with some water..blow it out with a air compresser..put it all back together...don't let the dealer or mechanics tell you the case has to be split ..THEY WANT YOUR MONEY !..lol

You just pour it straight in the crankcase? I have the cylinder off already and it's being bored right now. I'm just a little gun shy after being told the top end kit might not last as long as it takes to break end.

I've never really had any problems and I don't split the cases, but if it was owned by a "mudder" who sunk it in deep mud and water a lot, it might be a good ideal to do that. If not, I wouldn't worry too much about it. If you don't know if the previous owner sunk it in mud, just look at the engine. If it's been sunk in mud a lot, the engine will be stained by mud and have a brownish color to it.

Agree^^^^ you can also flush the engine with Hydraulic oil it's thin and works well.

The motor is stained brown and will not wash off with a pressure washer. It had been treated rough no doubt. I guess I will pull the motor out and just flush the crap out of it with what y'all recommend.

Yeah, if it's stained brown, it's been in a lot of mud. You may be OK by just flushing it out like they said.

I would definately Flush the engine with diesel fuel, wont hurt anything just make sure to take it off of the Frame, Getting a friend to help might be a good idea make sure to tile the engine in all directions to make sure to get all the diesel out, I would probably let it sit for a day to dry also, as for dirt in the pullstart side getting into the bottom end, is'nt that sealed? Let me know how it goes

It must be sealed poorly, because a lot of mudders, take that off and put a block out plate over it.

Both machine guys i talked to said to block off the pull start with a kit that cost $60.

Yep, that's what I wouldn't like about the block off plate. I like having the backup starter.

good info. do you not use wd-40 after you wash it with water to get all the water out incase the air compresser dont maybe get it all out??? or maybe it does get it all out??

either way good info.
