Did a fair amount of disassembly today including removing the PTO clutch off so I can remove the motor. Also removed the axle assemblies to clean up and paint.

Pics of the engine with head removed.  I have someone interested in the engine and wanted to see what it looks like.

Got the engine pulled today with the help of my father-in-law.  I am surprised how easy it was to do by simply holding onto the motor mounts and lifting it out.  Much different than the K301 in my 120 which was like wrestling with a bear since there is no good place to hold onto it.  I also got the blower housing off and will clean it up for the next owner.

Made some Father's day progress on the 312 while the little one sleeps. I got the flywheel and stator removed from the engine from 81918 which has been sold. It will be going to Elkhart Indiana to be reunited with another '78 312 that has a sick heart. Also got the frame of 81918 stripped bare other than the brake rods and pedal assembly. The bottom side of 81918 is pretty crusty and I made the right choice to fix up 71632 as it was in generally in better shape. 


If anyone needs 312 parts I can hook you up.

I have not forgotten about this one so here is a quick recap of the project as it sits...

 

The orginal 1977 312 has been disassembled and the frame has been repainted.  It sits in the garage awaiting reassembly using the best parts of the two different tractors.  The 1978 312 (serial is 81918) has been parted with items gone California (axle and other steering parts used on a 140) and others headed to Indiana to revive another 1978 312.  The the Kirk inspired k301 Killer Kohler will go in the '77 and I plan to use it as I use my 120. 

 

While scouring ebay, I found that Kohler offered a muffler for the K series that used the Supertrap "disc" design.  I am familiar with this from the auto and motorcycle world.  They are really cool and take the edge off of an engine quite well without compromising the performance - as a matter of fact they require the carb to be set on the rich side because they increase flow that much.  I am considering this because I like different.  Not thrilled about the price so I am going to look for other possible sources.  Part number is 47 068 10

Still have resisted the muffler but really think it would look cool on the 312.  No progress with a bit of vacation time in Colorado.

Why would a trip to Colorado cause you to lose focus?


Oh.......... never mind.

Travis, My muffler throws up the exhaust and makes the smell stick in my nose all day, would this muffler prevent that? THX

Not at all... you are experiencing Kohler cologne - similar to Onan cologne but different.

While doing some fact digging I learned there is a cast iron version of the aluminum oil pan that I have currently installed on the Killer Kohler.  When I shared the plan on another forum someone suggest that as a better option than the aluminum pan since I am changing the mounting design.  I also learned the pullers love this cast pan and they are speedy.  I found one on eBay for a reasonable price (still seems a bit steep) but supply/demand drives price so I pulled the trigger.  This one was on a late 60's Cub 129 that had the K301.  It will be here next week.  

 

 

I am still wrestling with the idea of that groovy Supertrap muffler on it...

Little one is asleep, wife is working, and it is too dry to mow the lawn so I am catching up on this project.  Grabbed the HD degreaser and cleaned the rear end and some other parts.  The grease on the early machine rear-end is pretty thick even after powerwashing it at a local car wash when I brought the machine home.

More quiet at the house is garage time! The grease on everything is terribly gooey or impossible to remove. Grabbed Gunk jd cleaner and some brake parts cleaner at the local fam fleet store. Slow progress is good.
