Slow and steady progress. Really hoping to have enough time to finish this round of repairs this weekend.

Today, I modified the cradle a second time to make sure both the ISO mounts and the oil pan would bolt up. The cradle doesn't drop right into the mounts the way I would expect, but it does fit.

After that, I took the Kohler on to my bench and started to dismantle the shrouding and cylinder head. Found that the engine has been rebuilt once, has .010 stamped on piston and block. Some side play in the piston at the top of the bore and a little oil in the combustion chamber. It will need rebuilt eventually, but for now I'm putting it back together and making sure it stays cool and running properly.

One head bolt, the one behind the ignition coil, was completely loose, and the cylinder head had a good leak in this area and around the front stud. Cleaned everything up, inspected the cylinder bore and it doesn't look terrible, but again, I know it will need rebuilt soon so I'm not getting too carried away.

Installed head, made pan gasket, installed pan, and degreased the engine. It looks much better now and should get some decent airflow. The top engine tin was cracked and installed improperly so I welded it back together and made sure everything was going to fit upon reassembly. Whoever rebuilt the engine or had worked on it recently didn't have much of an eye for detail.

Fixed the trunnion slot , installed new springs and end caps, shimmed the pivots on the control plates for the hydro.

Installed fan and got the driveshaft in, ready for engine install.

Cleaned and painted the tins. Started fabricating new power and ground main leads.

Nice job on the trunnion repair.

You mentioned you reinstalled the head. Hope you trued the head first, or it'll be causing you problems in the future... Just saying, cause you didn't say if you did it in your last post.
Good progress.

Yeah, I forgot to mention that, and that I ran a tap through all the holes and a die on all the head bolts, lubed them with oil before assembly. Followed the manual's recommended torque sequence/torque values.

I know now where the Quietline series got its name.

This tractor just hums at wide open throttle now. Unbelievable difference from how it vibrated before.

I am a firm believer in the Cub replacement ISO mounts.

And the hydro - oh man....after shimming the plates and repairing the slot/installing new springs this thing is so much more fun to drive.

I also dropped the axle and shimmed the pivot point to get the front axle tightened up. Steering is great for a 40 yr old tractor.

The charging system works better than ever with the new leads.

I can't say enough, really. I'm super excited to get some seat time on it soon.

Glad to hear it!

Always impressed with your work. I've seen some of the stuff you did on 3000 series machines over on MTF. Glad to have you hanging out here.
