Big Engine Problem with my 782!!!!!
 

Hi Guys,

welcome back at the new Forum.

Yesterday, I removed the Cylinder from my not good running KT-17, and I see a big bad Surprise, and now, I have a very big Problem.

Georg:

At least you do not a hole in your crankcase.

This is not that big of a problem. I had a similar problem with mine

Looks like at the least.....
(2) new Pistons/w rings
(2) new Connecting Rods
(1) Gasket set

That crank should polish up. I can't tell from the pictures if there are gouges or not. It can always be ground down .010 inches.

Georg:

Be sure to look on the crankcase half opposite the cylinder that had the broken rod for damage...Usually, a piece of the rod puts a hole in the block in that area...you are extremely lucky if it didn't.

Hopefully there is no block damage! Best of luck to you Georg. o7

Hi There Georg. !! :)
Glad you made it over to this side.
That don't look too good on that engine , but I know you will get it back running soon.

Took me awhile to realize by clicking on the pictures that I can see bigger ones.

still getting used to all these new things.~~~~ LOL

Sorry, to see that Georg. I know you'll have it back together, in no time. Good to see you here, on the new site.

Broken things are not good. I wish you the best of luck getting it running again! Glad to see you over on the new site!!!

I wouldn't put a penny let alone a euro into that engine. They were junk to begin with. That's why you see so many 782 hulls for sale on ebay. Find a nice twin to replace it. Vanguard or something. These engine were fine as long as the tractor was being used on the level, since it only has a splash oil system. Get one cylinder on the uphill side and oil starvation. Good luck !! Glad to see one old Cub made it to Europe.

If I remember correctly from his thread on the old forum, it's a series II, and therefore worth saving if possible. I think he said it had more than 3000 hours on it. It's still a lot cheaper to fix up a series II than to get a brand new motor of any brand. You can get new pistons and rods, and there are a lot of good, used cylinders around that can be bored oversize.

Hadn't seen the previous post. 3000 hrs !!! Still I wouldn't throw money into it without some sort of NDI on that block. I have gone this route before and it just doesn't pay to zero one out.

Yeah if that's a Series II with no block damage you'd save a fortune just doing a freshening up of that engine. It'll last many more years.

Hello, I'm back with good News,

been a long Time not here, but now, i've a little Time to tell you some new about my Cub Engine,
It was yery difficult to get the Parts for it, but i got them finally in Summer, i got new Undersize Rods, Undersize Main Bearings, Piston Rings, Gasket Set, and a Fuel Pump.
A used Cylinder, with Piston i got from Scott,(thanks).

My Engine Rebuilder grinds the Crank on 0.10 Undersize, made Valve Service, and grinds the Cylinder Bore clean, after i assembled the Engine,/without Heads), he grind the Valve Stems for the right Play.

Last Week in August, i moved the Engine in the Cub, and try to start, and after the first cranks, broke the Starter.
After assemble a new Starter, the Engine starts, and runs good, but not right, i think, at last, i made a Carb Service, spend new Breakers, Sparks, and Condenser, adjust the Carb, and now the Cub runs yery good, don't smoke, and have good Power.

Great to see you back, Georg! Glad you got your 782 going. Thanks for the pics. :beerchug:

That engine is definitely worth saving over putting a vanguard or something else in it.
