clueless 3,258 #1 Posted July 20, 2016 Couple of ?s. I'm in the process of replacing a cracked head with a nice reconditioned one. Have a new kohler head gasket, do I use any gasket sealant? Didn't use any on my two k91s and they seem to be fine. Also replacing points and condenser,and would like to set them statically. Can't find the "S" or the "T" on the flywheel, there are three dimples on the flywheel, are the S/T marks close to them? Chris. Share this post Link to post Share on other sites
Achto 29,408 #2 Posted July 20, 2016 I would not recommend using any sealant on a head gasket. They should only be installed dry. 2 Share this post Link to post Share on other sites
rmaynard 16,342 #3 Posted July 20, 2016 No sealant required on a head, just a new gasket. The dimples are for balancing and can be anywhere on the flywheel. The S & T marks to the best of my memory are located as follows: View the flywheel from the front (fin side) with the keyway at 12 o'clock. The S & T should be at about 10 o'clock. I know this is true for the K241 and larger. Not sure about the K181. 1 Share this post Link to post Share on other sites
clueless 3,258 #4 Posted July 22, 2016 I removed the crankcase breather and cleaned it, and have a new filter and two new gasket. Before I reinstall it does the reed valve face the valves or does it face out. I'm pretty sure outward but starting to second guess myself, may be the heat, may be the amber liquid, probably both.

rmaynard 16,342 #5 Posted July 22, 2016 Crankcase pressure (piston going down) should push the reed out. Negative pressure (piston going up) should try to pull it closed. The assembly instructions are in a diagram in the K-Series Service Manual available for free download from our manual/files section. 1 Share this post Link to post Share on other sites
