Running egine out of tractor

I have a TED20, tractor is split, motor sitting in truck rim on blocks, clutch and flywheel removed.

I want to run it to test the rear end seal.

Question is, Is it OK to run engine without the flywheel?

How much movement can i aspect from the engine when running, will it sit happily on some timber blocks or should i chock it to stop it running away?

Cheers: ps. Tony go easy on the shelia's
 
I've done that before, but you want the flywheel on it. How are you going to start without it? On an engine stand or cart would be best, and you will see the seal leak IF there is one..
 
Don't worry diesel tech. PCP was property master for all the Mad Max movies, he will start it with his teeth if he has too...but without a flywheel... if the rear seal didn't leak before.. isn't there a good chance it might after? you might thro off the whole balance of the rig.... come on PCP! fair go mate! 4 bloody bolts? weighs less than a case of Castlemaine in bottles? You've done worse! Step up to the 19th century and use the electric starter!!!!
 
Running a 4 Stroke engine with out a Flywheel.....new to me:

At some point on a Power Engineering Exam, I recall one of the duties of the flywheel is to carry the rotational force and absorb any energy between cylinders firing.....balances the time between each cylinder firing so as the engine is not jumping and leaping :

There are some Engines that the Flywheel is balanced to the Crankshaft and you must have the flywheel on the engine to test run it...or the Crankshaft shall experience failure:

I built a stand were I test all TEA-20 Engines before installing them:

I'm interested in the out come:

Thanks:

Bob...
 
If all you want to do is check the rear seal, couldn't you just stand the engine up about 45* so the oil will flood the seal area?

Cheers bob, this was what i was wondering, now someone has said it it all make sense. Or in technical terms it could, maybe, all go horribly wrong without the flywheel on.

I was going to crank start it, tony, using your teeth, that plain stupid, I was going to hook up a pull start:shock:

nice one steve, another thinking man, wondering why i did nt think of that, recon i might try that first..

Now Tony, my old son, lifting a fergie flywheel is not that light, with tennis elbow in both elbows is bloody painful, maybe I could borrow a couple of your Shelias, cobba :D,
on second thought, NO :idea:
 
50 pounds in old English. Cause any heavier the US post office wouldn't ship it.
No you don't want her to help you with this, even tho she's probably a short drive from you? She could handle it if she was p!$$ed off and wired up... but you don't want that...
???? Now the engine is on the ground? and the flywheel is already off? ... Standard petrol.... i forgot- how many more nuts and bolts?? to just change the bloody thing while you are already this close???
Was that rope or rubber ring seals?
 
Info on Flywheel:

It will make a difference if the Flywheel is not installed as per factory installation:

EG.. "Ignition timing and Static rigging"...1/4" Diam. hole below Starter must align with 1/4" Bore/Hole on Forward side of Flywheel ( Insert 1/4" Diam. round stock) at the proper degrees before # 1 Piston is at top dead center on Compression Stroke:

(quoted from post at 08:17:46 06/16/17) I do not think I would run it without flywheel.

you'll be glad to know, that i have been contemplating the 45 degree angle, hence, the motor is still sitting on level ground ... I think i ll replace the main bearing after closer inspection...
 
Are the bearings STANDARD or UNDERSIZE?

Are the Journals rough enough that you can feel the roughness with your fingernail?

Bob...
 
Well, yer in the right direction- if the seal leaks, besides age itself, it would be the wallowing around of the crank journal- cause the bearing is too worn- so IF the seal is still good, might be the main bearing is still good..... or- did you already tear all this apart? If you did, no better time to do bearings and seals etc etc.... cause if you opened a can worms? might as well go fishing!!
 
Woooo up there texas... As said motor is still sitting on the ground.... I meant to say in my last post, replace rear main seal NOT bearings...bearings are all honnky doory ( good)

I am still in contemplation mode...the seal is orange and i cannot see a split in it, its a little rough down the bottom so thats why i decided to change it, Not doing bearing etc as they are all good.

So plan to flip motor, remove sump, remove the rear seal bridge/cover, undo rear main bearing and replace seal, re torgue rear bearing cap and replace..... :arrow:

finally got around to steves suggestion of titling the motor, once I got the crane setup. It did not take long,there was a constant drip as soon as i got to have a look,so that question answered.

Just bought and engine stand to do the job, Rolling motors around on the floor is a mugs came, hay Tony :p
 
Yeah.. when that Chinese engine stand keels over onto the floor... or your foot... you will say 'Tony was right! Where's a bloody wooden pallet? And a sheet of cardboard to sit on the floor and work on this engine? Who wants to work standing up when you can lie down???
