Damage from toppling a tractor?

Start a thread in owning and operating. I'm sure you'll get the info .

This is one of the good reason not to disconnect the seat safety switch. I turn my TC 40 on it's side a couple of years ago. When I got off the seat the engine stopped before the tractor landed on it's side. Needless to say I had to change my pants after that. We turned it back over with a wrecker and let it sit a couple of hours. Then I checked the fluid levels and everything was OK. I started up and everything worked ok.

Yeah, you're right...I didn't proof read the post...Duhhhhh!

As far as the engine turning with oil filling the volume above the piston...well, never saw that.

It can happen , If oil gets on top of a piston ,I've had many bent push-rods from this ?

I short blocked a Cat 3208 in an end dump that had turned on its side and then they tried to start it after putting it back on its feet. Bent a connecting rod which the next day was thrown through the side of the block. Ugly mess!!

So Yes oil can get in the top side of the pistons and if it does, it will create havok.

If you can manually turn the engine thru 360 degrees using the crank bolt and a long breaker bar, you are good to go.

You'll need to rotate it 720 degrees to be sure all cylinders go through a compression stroke.

 

[MJPetersen]

While it is true that 720 degrees would be necessary for all cylinders to go through compression, it is also true that each piston will have been at the top of the cylinder either on compression or with an exhaust open. That also would do it. It is also true that only a rev or two could leave significant oil still in cylinder, but not enough to cause harm.

The obvious thing to do in the case of a roll over is to pull the compression release and then crank it a few revs. That will clear the cylinders and bring up oil pressure.

Not all tractors have a compression release. I've never seen one on a CUT.

Almost all Yanmars CUTs have a compression release. I am not familiar with other brands.

You are probably right Roysince I'm not familiar with other tractors, but my Kama and other Chinese tractors like Jinma have them too.
Originally designed for ease of starting but I've found it can help pre-lube the engine when cranking it over in the mornings. Turning the engine over a few times gets oil pumping into the bearing journals without load imposed by a firing piston. Of course I don't use it all the time during the rest of the day.

You don't need to put a 3208 on it's side for it to do this ...HaHa A guy i know had a 3208 in a tractor and and it had both heads replaced , 200 hrs later it punched a con-rod out through the block ,Rebuilt again and another 1000 hours and a piston hit a valve ,He had it rebuilt 1 more time and sold it to me and it's done 3500 hrs beautifully .
