Kohler OHC camshaft engine timing


I have an 18 HP Kohler engine on my lawn tractor. My guess is that it's about 10-15 years old. It is the OHC model with this information: Family: TKH574V1G2RA Model: TH18S Spec: 54511 Serial: 2722303602
It was not running because of some bad gas that I put into it last year. I broke it down to get it all cleaned up and got carried away and pulled the pistons out to check the cylinders. When I put it back together I did not have the special Kohler tool to set the timing. The tool (28-761-01) to set the camshaft timing has been discontinued so I cannot find it anywhere to buy. Does anyone out there know how to set the timing on an engine like this? Do I need the special Kohler tool or can I just eyeball the timing setup? The 2 cams are at the top of the engine and I have some directions in the manual but it says to use the tool but not how to use it so my guess is that it has it's own set of instuctions. The local dealers are not interested in helping.
Thanks! ~cj

Betcha next time you'll just pull the plugs and borrow a borescope. :')
Surely the manual explains cam-timing in some detail, no? And, is it continuously, or stepwise, adjustable?
If all else fails, I'd try to set the center of the overlap at TDC. Might need a dial-indicator or two, and whatever can be fudged up for a degree-wheel.
Or, just drop the engine off at local dealer. Sounds like there's some blockage with that. :')
Lotsa luck, J

I'd give Kohler customer service a call. If the engine people are as helpful as the plumbing folks, you'll have your problem solved in short order. They may be able to help you find a more cooperative dealer if copies of the instructions aren't available. Good luck.

I believe that spec number puts that engine in a Simplicity tractor.
I'm assuming the following is the manual you have: http://www.kohlerplus.com/login.asp guest login>under service manuals click TP-2480 scroll to page 11-10/11/12
I think the tool only held everything in place until you wrap the belt and set the belt tension. Probably a straight edge and some light c-clamps would suffice. Or a helper who can follow instructions.

I too am up against setting the timing on a TH18 Kohler. I found the timing tool for $35 but would like to see a picture of one. If its as simple as 4 pins on a straight bar holding both cams in a horizontal position than i can make one.
Does anyone have a picture? I am going to go to my nearest dealer but am covering all bases to try and see what this "tool" looks like.
thanks.

I couldn't find a picture. The above is what I got from reading the instructions in the manual.
