109
 

Time for a refresh on the 109, don't know yet if it's the first in 50+ years but it's the first in the 18 years I've owned it !! It's been needing it for a few years but everyone else's stuff kept me from it, kinda like the plumber with the leaking pipes in his house ! Taking some time to work on mine so it quits huffing smoke while it's working !

Well then, we're gonna need lots of pics. Looking forward to your rebuild. :popcorn:

First time I seen a k series Koehler on an engine stand. Looks good. Good luck with the rebuild

Yes sir! Please do take lots of pictures.

Looks nice and clean.

Yeah, they're not the easiest to mount

X2, :popcorn:

Remove the starter mtg bracket and bolt right up, much better than trying to roll around on a work bench, been doing it this way for years ..

I get that, but maybe it's my engine stand. It's a pain to get things aligned nicely. I should probably make a plate for just for Kohlers.

Yes, lots of pictures

109 update
 

Got a little time to start disassembly of the 109's power plant ! PTO and basket pulley safely removed ,crank and key-way look great ! Some visible wear on the cyl wall likely will need to go .010 over or .020 if needed once I mic it ! The head looked normal and the gasket was not showing any issue other than age !

back together
 

109 engine back together and running fine ! Bored .010 , long stretch from start to finish due to 2 weeks in SC and block at the machine shop 3 weeks ! Hi spots sanded from head and block deck stoned ,adjusted valves and static timed in engine stand, fired in about 3 revolutions ,heated up and cooled, re torqued head 3 times to 28 ft lbs, installed remaining shroud and air cleaner housing. Sorry I didn't get more pics of the process along the way ! Didn't get to plow any snow but it's ready to mow !
