Flywheel nut torque

[Elliot Garfinkel 166]

Hi all trying to button up this k161s have a couple of questions. First does anyone know the torque  settings for  flywheel nut , in  three different  manuals I get  50 ftlbs,65ftlbs or 75ftlbs. The second question is their a timing mark on bearing plate if their is I cant seem to find it,I got the 2 on the flywheel.  As always thanks for any help

My manual says 85 to 90 ft. lbs. with a footnote that says 45 to 55 ft. lbs. on serial numbers prior to 23209832

Set the tin flywheel shroud in place.  Locate the hole on the lower left side of the shroud that you look through to check the timing.  Looking through that hole you should see a raised "-" dash mark on the aluminum plate.

PS before you put the flywheel tin on I like to paint the area where the timing marks are on the flywheel white, then use a black sharpie to mark the timing lines on the flywheel.   Sure helps to find them when your looking through that little hole in the tin.

Thanks for the fast response  the only hole I have for timing is on bearing plate nothing on the tins.

I have found the mark on the outside of bearing plate to the left of the timing access  hole .thanks again

To set the timing you will probably need to use a timing light. 

Ignition timing on Kohler engines.

 

Gapping the ignition points at .020 has always been the standard answer to how points should be set. That probably will get you into the ballpark where the engine will run, but with a bit of additional effort you can improve the engine’s power and performance.

The Kohler engine manual in the Red Square files section covers two methods for setting the ignition timing, Static Timing and using a Timing Light. This manual is a relatively new manual and it overlooks the fact that many of our engines were built prior to the ACR (automatic compression release) camshaft.

Earlier engines (mostly 1965 and earlier) had a Spark Advance camshaft that can not be timed using Static timing. At rest (and very low RPMs) the timing is retarded to fire slightly after TDC. The timing mark (SP) on your flywheel is at twenty degrees before top dead center but at rest the points on these engines break about ten degrees after top dead center. The only reliable way to check or set the timing on these engines is with a timing light.

There are a couple ways to determine what camshaft you have. Presuming the camshaft in your engine is the one it was born with the data plate on the engine has a suffix that can tell you what camshaft was used. The table below will tell you the suffix applicable to your engine. The other way to determine what camshaft you have is to remove the cam gear cover and take a look. If you see a mechanism attached to the cam gear it is the ACR cam.

 

 

The following engines have the spark advance camshaft;

K-141, Suffix prior to “C”

K-161, Suffix prior to “J”

K-181, Suffix prior to “D”

K-241, Suffix prior to “D”
