Scotty... I do not yet have a shop manual. I will admit and claim complete ignorance here. This being my first tractor, that came with zero instruction & no operators manual, I don't know what all the levers do what unless eliminating through trial and error. Long story short, I had a mobile mechanic come out months back that gave me a TON of info on the old Yanmar. One thing he pointed out was the LOCKER foot pedal. He says, "so, if you're ever stuck with one wheel spinning, just mash down on that lever and now the two tires are locked together. It will disengage by itself once tension is released on the drivetrain". So.... Your explanation of "someone" trying to engage the locker with wheels spinning might very well be the case. Operator error! However, when the failure occurred, the locker had not been engaged, attempted or anything like that. I was simply just plowing a pile of brush.
Unfortunately I had a VERY busy week last week with kids school programs and other commitments. I wasn't able to get into the issue hardly at all. So, here is the latest update.
Backhoe has been removed. I've never done it before and neither had the friend whom I purchased the tractor from, so it was a learning experience. I have the tractor in the shop with the PTO shield & outer perimeter PTO case bolts removed. As of yet, I've been quite unsuccessful in actually removing the PTO cover. I'm afraid to remove the 4 larger inward bolts as i'm assuming that's what is hold the gear set together inside. She doesn't want to let go of her seal and I'm afraid I'll break the case if I smack it any harder.
So, I'm stuck without a solution, unless there is some sort of "liquid" solution out there that might dissolve really old gasket material? I'm open to suggestions at this point. Thanks
That's too bad, but water under the bridge now.
The person who advised you forgot to mention a very important fact about the locking differential. For example, engaging it via the foot lever simply uses brute force to physically connect one rear axle to the other. It's about as subtle as dropping a big old bolt into a gear box. It is something to do carefully and with nothing moving....or at worst with a tire rotating very slowly. Once engaged, you can add power without a problems But trying to engage it with a spinning wheel is a sure fire formula for breaking things internally. So the locking differential may not BE your problem, but if you engaged it with one wheel spinning it darn sure may have CAUSED your problem. And that propblem could well be a broken tooth somewhere inside. In the intermediate(bull) gears, the transmission gears, or the differential planetary. But probably only one. .
Tacoa, I'm going to be blunt here. With a 240D and a backhoe you have at least $6K worth of tractor that is now broken for lack of a few hundred dollars worth of manuals. You ought to fix that situation before you fix the tractor. Yes, it is worth some wrench time. These are classically good tractors. You just had bad advice and worse luck.... maybe..... and maybe you'll still get lucky.....
BTW, I have no idea whether taking the PTO off will avail you anything. What makes you think so?
And as far as I know, there isn't anything that will dissolve old gasket cement from the outside. Normal procedure with a stuck cast iron cover is to pry it apart - very carefully with feather-thin wedges and prayers for luck - tap, tap tapping it can take an hour or more very easily. Then you scrape the faces clean. For reassembly I use a CURED layer of silicone sealer smeared onto my paper gaskets - but it's a method that takes careful prep.
Again, why are you taking that PTO cover off? What do you expect to find? Or is it just convenient?
I am thinking yoy need to get an operator's manual, plus a Yanmar shop manual for the 240D or 195D - NOT the Int'l Tractor or IT version for one manual fits them all....nor do you need the flat rate manual....or the supplemental shop manual. You need the basic Factory Yanmar Shop Manual - the real deal. And last but not least, a genuine Yanmar parts manual. These all come up on Ebay all the time,
With these the forum members here can help.
I see on Ebay that there is an original operator's manual for your 240D right now for 20 bucks. In there you will find things like a warning not to forcefully engage that foot lever with the wheels spinning.
Expect the shop and parts manuals to cost 50 to 100 bucks each. Much more expensive than the operator's manual
I believe that the YM195D is very similar to your 240D tractor, if so a YM195(D) manual would be usable for procedures.
