  • How easy should I be able to turn over the engine by hand?
  • So, I'm still troubleshooting this no start thing. I have a new battery,starter and solenoid. When I try to start this thing, the starter just makes a humming noise, like it is trying to engage, but it can't. I hooked my starter/jumper directly to the solenoid, in case there was a wiring/switch problem, and same thing. Its acting like the starter is not strong enough to turn the engine over, or like the engine is seized. After talking to folks here and other places, this doesn't seem likely, especially since I was using the tractor and it had no sounds indicating an engine about to go. And the last time I used it, it started hard, but was running fine, I turned it off to hook up a trailer.

    My question, how easy should I be able to turn the engine over by hand? I know these had high compression, and I'm a pretty strong guy, and I cant seem to turn it over by grabbing the belt. I tried putting a screwdriver in the starter hole, as well as the inspection port looking thing on the right side of the tractor. I feel like my screwdriver will break or bend before the engine will turn over.

    Should I be able to turn this over by hand? I removed the plugs, thinking that might make it easier, but no difference.

    Any thoughts?

  • You need a hand crank.Engine is stuck from sitting idle.Using the rear wheel dosent give the feel you need.The clutch can slip and fool you into thinking the engine is free.

  • Marty,You said,Bad news, did the one wheel thing, and no movement. Now what?Well,did it loose oil pressure the last time you ran it.If you can't turn it with a pry bar,plugs out,starter out you have problems.Time to pull the engine and tear it down.The rods and mains,or the pistons are seized up.The engine has to have oil pressure to stay running.

  • Hand crank is a good idea but most of us dont have one. I watch the fan belt to see if the engine turns either way.
    I know with my 8n I jack up the left rear wheel put it in 4th gear and turn wheel forward. It is very easy to see the fan belt turn from that side. Also works when checking point gap.

  • Put tractor in high gear and rock it back and forth and see if engine moves. It should.
    You can also jack up one back wheel with tractor in high gear and try to spin that tire. Engine should move. If not you are stuck. You can try to pull it with another tractor and see if the engine moves, but go slow and don't horse it or you may break something.

  • Marty, first things first. What tractor, what year, 6 volt or 12 volt, how long has it been sitting, did it run when park, did it ever turn for you, do you know its history??
    Is the hood on it, have you had the head off, when is the last time it ran etc.

    First thing I would do is put some MMO in the cylinders and get a big wrench to turn on the front main pulley bolt. Then I would let it set for a few days. Some folks also use ATF. MMO= Marvel Mystery Oil. ATF automatic trans fluid.

    After a few days or a week, I would work back and forth on the front bolt to try and turn the engine back and forth just a little. Once you get it to move, you just work it a little bit at a time back and forth till it gets loose. Then you turn it forward till you feel resistance again and then work it back and forth till it gets loose.

    There may be a how to in the How to section. I will look and post back.

  • If you look in How to's on the red bar at the top of this page click on it and go to Engine, and then to Starting engine after years of storage...

  • It wasn't in storage, I was actively using it. Now I've only had it for about a week when it started acting up. I literally turned it off to move a trailer to hook up to it and I wanted to go turn it back on again it wouldn't start. That's when I started swapping parts like the battery and the starter. It's strange to me to think that the engine would seize up, because it was running fine then suddenly stopped. I thought no big deal, throwing new starter in a battery on it and I'll be off again with it. But that's not how it went down. I tried pulling it today while in gear and the engine won't turn, I also tried jacking up one tire and putting it in a low gear and turning the engine, and that didn't work either. I guess it could be seized, that just seems like a strange thing to happen to me

  • Marty, one thing, you should put it in high gear when you turn the tire or try to pull it. It may be opposite then you would think but in high gear you have more leverage to turn the engine with the tire. What kind of oil pressure did you have prior to this happening? You are right that it is odd that you would shut it off and then it would seize up. Something could be jammed. Did it have OK oil pressure?? Like 20psi when hot??

  • Awesome idea! I will try this tomorrow and see how it does

  • I also meant to say that the starter bendix could be jammed to the ring gear. Sometimes rocking the rear tire back and forth while in high gear will kick it loose, so be careful. Good luck with it.

  • Marty,If you can't turn the flywheel through the hole with a pry on the flywheel teeth,something is wrong.Is the starter still on it?If it is still on it the drive could have it bound up.Loosen the starter up or remove it and try turning it with a pry through the starter hole.

  • Nope, starter is off and plugs are out
