800 Cub resto project
 

Hey guys,
I have been wanting to fix up an older garden tractor and after some research I decided that I wanted a Cub Cadet 800. I was able to find one on Facebook Marketplace of all places.

It doesn't run and looks like it need a complete overhaul from one end to the other. According to the serial number it was built in mid-1975 and has a Kohler K181QS motor. Is this the correct motor?

If any of you have one of these 800's please feel free to share your restoration tips or pictures of your tractor! Thank you!

First, welcome to OCC....:Welcome2:

Here is some 800 data:

800 - S/N:530,000 - 664,996 - Yrs: 74-80 - Engine: 8hp Kohler - #K181QS-30545

Hello and welcome. Nice pickup for your first project.
Yes, the K181QS is correct and if it can be rebuilt parts are readily available.
If it needs replaced, sometimes not so easy depending on your area.
There would be nothing in particular that would be different about restoring an 800 than any other cub. But the fact that it is of the QuietLine series, your biggest concern will be with the rubber motor mount system (aka iso mounts). When they are shot, a lot of damage gets done because of engine movement.
Another area will be your clutch. The gear drive Quietlines use a flex disc as a clutch plate and when the iso mounts go bad and let the engine move around, the flex disc ends up cracking. If it all needs replaced you would have the option of using original type parts ($$$$$) or solid motor mounts and old style clutch parts.

You should get famiiair with the Tech Library, your gonna need these....

Thank you both for the info. How expensive are the original Quietline parts such as the iso mounts and the flex disc? Where would a man find them?

This tractor seems to be original, just been used alittle. According to serial number it was made in mid-1975.

Too bad those A** Holes over at PhotoBucket have to impose their logo's on your pictures.

800Cub: Good luck on the restoration. Make sure to post a lot of pictures as you go along!

CAD: Good looking 800!

They continue to demonstrate why they're one of the pariah's of the internet (after wrecking almost every online forum by removing image links in established posts).

"Doesn't run" could be as easy as a carb replace/rebuild, cleaning points and fuel flushing. I'd start with the easy, as if the engine is free and has compression, it'll likely run. These old things are incredibly reliable machines.

Nice 800 you have there good score for a first cub. I would not be surprised if it just needs a little carb cleaning, and clean up the points a little and give the wiring a quick look over for any major damage. And have fun ( yours looks better than this poor 800 I picked up a few months back.)
