Take a look at my "new" Kohler K321AS I picked up for my Jacobsen GT14.  Bored .010".  Valve seats done.  New Kohler top end! 

 

The gentleman i bought it from made it a stand alone unit... Custom frame underneath - custom switch box for start and kill switch.  Custom gaurds and gas tank mount.  He was going to put it on a snowblower but lost interest.  My Kohler is already .030 over and it is smoking.  This should make a great replacement!  Almost a shame to undo all the work this guy did to put it in my tractor!!

The Kohler looks sweet. What made the preference for the neon green paint or was that from his custom job?

 

Should make for a great new power plant for your Jacobsen GT14. :thumbs:

The green was from the previous owner.  I guess the motor came from a Deere originally.

With that style of oil filler tube, it's from a 1969 or maybe even an early 1970 model JD 140. Later models had the tube coming off the top of the block there instead of the side. You need to check to see if your PTO clutch will mount on that block, I couldn't use any other block but a Kohler built for the Ford/Jacobsen tractors.

Why was that, Brian?  Mounting holes for the brackets different?

Yes Ben, the bolt circles aren't the same. The JD block could be drilled and tapped to the proper size, but there was some other reason why I didn't do that. There may have been a difference in the bottom of the block also.

This may help you out with your question about block differences. I started this thread a couple years back.

I think that there are wide and narrow block variations with the K321AS. I also think the dipstick tube length will have to change because the Deere uses an oil pan but my Jacobsen uses a welded in oil pan. One way or the other - I will find out!

My 1970 Jake Super Chief 1450 has the wide block K321S.

So the clutch is different. I can modify my Jacobsen clutch plate to for the JD block, but my Jacobsen has a 1-1/8 shaft whereas the JD only has a 1" shaft.... I'm thinking of making a spacer to accommodate the different shaft size. It would be a pretty thin spacer but it just has to take up the space right... Bad idea?





Yes Ben, the bolt circles aren't the same. The JD block could be drilled and tapped to the proper size, but there was some other reason why I didn't do that. There may have been a difference in the bottom of the block also.
