As I near the completion of my 100 (http://www.mytractorforum.com/19-cub-cadet-forum/1073265-new-me-1963-cub-100-a.html) I have been on the lookout for an original. I was lucky enough to come across this one serial 26791 only a few miles from home. The clutch is apart in a box. The PO took it apart and then I guess decided not to complete the project. It is also missing the S/G.

I am excited to dig into this one when I get time. Just something about these old machines that gets to me. Guess I should see a Dr

Great pick up! Very neat old tractor. Should we be looking forward to another restoration? You'll be waiting to see the Doctor for a while. Lots of us ahead of you.:tango_face_grin:

No attachments. Still need to do a complete review to figure out what is missing. I started looking through the box of clutch parts. Should be interesting getting that back together. At least I did the 100 clutch so that familiarity should help.

Then yes a restore.

Waiting on paint to dry on the 100 so I started to look at the Original. Decided to pull the head, probably a mistake, but it is done. All bolts came out fine except the one near the exhaust. The good news is it is about 3/8 proud of the block. Better news is piston and valves all operate as expected.

Looking for suggestion on getting this out. I can't get two nuts on so that approach won't work. Should I weld a nut on it? I heated it a bit and squirted it with PB blaster for now.

When I pulled the carb off I noticed the governor arm seemed to travel more than it should. Further investigation and the governor shaft came out when it should not. The flapper was broken off. Glad I had not tried to start the engine as it would have really raced. So now I need to pull the oil pan and look for the part and see what else might have been damaged. That was the other day. Fast forward to today.....

Rainy day did some painting on 100 and then worked on the engine. Pulled the oil pan and found the broken piece from the governor arm, but then I saw another small piece. That made my mind up for me, I need to take this all apart to look for more damage. I tried drilling the set screws out ( as someone else had already damaged them ) of the pulley after about 30 minutes and not much to show for it I decided to cut it off. No plans for any attachments.

The larger pulley that runs to the S/G was not too bad. The set screws had been rounded but I was able to drive in an old metric Allen that was tight enough and with some heat they both came out. Pulley came off with just a little bit of effort.

Pulled the piston and found that the skirt was broken and you can see the notch that the governor arm piece made in the piston. Amazingly the cylinder has no damage. Always better to be lucky than good !!!!

I was also able to get the exhaust completely apart. Maybe all the heating I had done to get the broken head bolt out helped since they are right next to each other.

I mentioned earlier that there was very little oil in the engine. Everything inside is coated with a very sticky black tarry consistency film. Again no cylinder wall damage!!!

Tomorrow I will try and get it cleaned up real well and measure for tolerance.

Very thankful that the damage is manageable. Everything damaged can be replaced.

My very rudimentary measurements show the cylinder OK and the crank at the high end of OK but since the cylinder has a lot of scratches ( probably because of the filthy low oil) I decided to take it in to be professional checked. Today I decided to mess around with the wiring so that when I get it back together I can at least test things out. Using the existing harness and pieces from my old butchered 100 harness I connected up things according to the wiring diagram. Wire color coding is not correct but point to point I should be OK. When I actually get into the restore I will order a new harness from Mike. The push button was still good, but the key switch is open so I just popped in a single pole switch for now. What was interesting is that the gray wire that goes from the push button switch to the VR was on the wrong side ???? There is no way that the battery would have been recharging the way it was. The switch was not mounted and the nuts on the posts were that tight, so I suspect someone might have messed with it. It should be on the same side as the battery cable, but it was on the side of the S/G armature.

Nothing much to report. Been slow going over the last few weeks with other activities. I did get a real nice NOS muffler and elbow.

Engine still at the shop waiting on parts.

I was soaking and heating the steering wheel for the last two weeks. Tried PB blaster, bees wax, to no avail so I finally cut it off today. Someone had tried putting a 5/8 - 16 nut on so the threads were already a bit messed up and of course I nicked them with my grinder, but they cleaned up nicely with 5/8-18 die. Did a test fit with a spare wheel and nut and works fine.

The throttle cable was missing and the choke cable would not move. I took it off and coiled it up in a pan with some PB blaster and let it sit for the last week plus .Today I was able to move it so I think I have saved that piece. I do have the lever for the throttle and it cleaned up good, so I just need to come up with a cable.

I was able to find a nos muffler from pats small engines actually. I think they only had a couple left iirc. I need basically all electrical and cables for mine. Other than that she's ready to go. When I got it it had been sitting outside and the transmission was full of water and rust. Once I got it apart it all cleaned up great, but had a couple broken gears. Replaced those, all new bearings, detents and seals.

She runs good but will need a rebuild of the engine and clutch. Aside from that, just body work and paint. Ill be honest though, as much as I love doing it, I needed the summer off from restorations.

Thanks Bill! I've been wondering how you keep up the pace, yours are spectacular looking restorations! Keeps them alive, which I'm a fan of.

Bill, what kind of condition is your oil bath air filter in? On mine the bowl was rusted out. I was lucky enough to find a nos bowl. The rest was fine luckily. They go for some decent coin in good shape!

Oil bath is in very good shape. I took all the packing out and cleaned thoroughly. I was even able to wash out the packing and reuse it.

I picked up this model 72 near me for a few parts. Mainly the narrow tires and very nice seat. Mine is rusted through. It also came with the k161 and he threw in a k301. There was a box of other miscellaneous parts including a nice steering wheel.

I have spare wheels from my 100 restore that I will throw on this and see if I can get the engine running and try and sell once I take what I want. I won't do a restore of it. It is an upgraded model with headlights.

Piston and rod came in today. Will drop off at machine shop tomorrow.

Yes it is in very good shape which is why I will try and save it unless I have to spend a lot on the engine.


Dropped off the piston with machine shop so he can make sure everything fits properly. Ended up having to go to .020 over and I stuck with Kohler parts ( piston and rod) I couldn't find any aftermarket parts for the small bore K161 anyway. Maybe I didn't try hard enough. The only Kohler parts I could find was .020. Crank was still in spec so standard rod.

Rolled it out of the barn to power wash off the years of grime grease and oil.

I did pick up a universal cable for the throttle cable at local auto parts store, just need to cut to proper length once I drop the engine back in.

Current plan is to drop the engine back in and get it running then move on to the clutch which if you don't recall came all apart in a box. I also noticed today when I took it out to get washed that the brake does nothing so will need to look into that. I don't plan on doing total restore this fall, just take care of the mechanical issues with the paint next year. Caveat is that the parts that I work on like the engine and clutch will get painted while they are all apart.
