782 is shaking at Low Idle?
 

Today, i started my 782, after 3 Weeks without working. The Engine started good, but i think, thats not all ok.
The Motor is not running perfektly, the Tractor is shaking a Little bit at Low Idle, (hope it's the right Translation).

Here 2 Videos, (my first), on Youtube.

Please look at the Grill Housing, it shakes lightly, and i think the Motor makes a wrong Noise at running, (not a mechanical Noise).

The Motor was rebuildt completely in 2009.

Hope i'm not to angry with my Tractor?

Seems normal to me...dad's 782 shakes a whole lot worse than that. I like the tri ribs on the front wheels.

Sounds like it is missing. Pull the plugs and check them out. If one is black and the other is not, do a quick compression check. If both spark plugs look the same, do a tune up on it, including pulling the carb and cleaning it out. If the compression check shows low on one side, I'd be pulling the heads. It's a video and it is really hard to tell if it is distortion in the audio..... but I think I hear a leaking head gasket. :bigthink:

BTW: REALLY NICE 782!!

You will probably get different opinions from everybody.One thing is for sure though,you know your machine better than anyone.If you think something is wrong with it,then it probably is.Im sure someone will hit on the problem,always a bunch of good suggestions on this site.:beerchug:

Thanks for the Answers.

The Engine got a complete Rebuildt in 2009, at 3311 Hours, with Carb Service also, new Spark Plugs and Fuel Pump. Now the Tractor have 3345 Hours.


If i disconnect the left Spark Wire, the Motor will not start, if i disconnect the right Wire, the Motor starts and runs on one Cylinder.
If i connect both Wires, the Motor starts good and is running, but not 100% round.

I think, i will check the Compression and the Plugs in the next Time,

Georg,

It sounds like you have some sort of issue with the LH side.

I had a similar issue with my 782 and it turned out to be a broken Connecting Rod.

I hope yours is not so severe.

Hi Roland,

the Motor had a broken Rod at right Side, if i purchased it in 2008.
Thats all repaired. New Undersize Rods, Piston Rings, Undersize Crank Bearings, Valve ans Carb Service.

With a broken Rod, the Tractor shakes much much more.

The Flex Disc Couplers in the Drive Line can become out of alignment causing vibration. As a suggest, disconnect the drive line (shaft) and see if the vibration is still there.

I do not have any solutions but thought it was so great that we can help our neighbors with a cub problem no matter how far away that neighbor is.

I was thinking that also, Roland.

Thank you Guys.

Today, i worked at my Motor, after i started it, it runs perfectly, after few Seconds, the 782 began to shake and run not perfectly.

I pulled the Sparks, and checked them, both are working, but the left one had a better Fire as the right one.
As next, i installed the Spark Plugs in the Motor and started him, if i disconnect the left Wire, the Motor stops, and if i disconnect the right one, the Motor runs on one Cylinder.
The same how few days ago.
After this, i changed the Connections Sides at the Coil.

The Problem was the same, but at the other Side, so i think it's a Problem of the Ignition.

Tomorrow i will replace the Sparks and Wires with new ones, i hope the Coil is not damaged, tomorrow, i will know more,

Georg,

I had a similar issue on a friend's tractor. It turned out to be the "metal cap" on the end of the spark plug wire was rusted and not making good contact. You may want to check.

See: http://www.onlycubcadets.net/forum/s...ad.php?t=27905

I encountered that very problem and it turned out to be a bad coil. I hope it is something less expensive,as they are not cheap.
Good Luck!
