My son and I just finished building a box blade from scrap (I'll post pics and a description later) and I was pulling my 126 in the garage. I heard a tapping noise
![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() According to the PO, I am the third owner and the engine has never "been into". If so, this is a very good track record for a 1971 tractor. I've checked the cylinder bore, crank pin diameter, cam and crank shaft end play and cylinder head for flatness. All are within specs. Crank pin has some visible lines, but none can be felt. It looks like either the rod suffered from metal fatigue or one of the rod bolts loosened. 1 rod bolt was laying loose in the oil pan. It may take a few weeks to get the money to order parts. That's one of the major problem with being disabled and on a fixed income.

Could have been worse! Rebuild it and get another 40+ years...

Sorry, to hear that, Charles. You'll have your 126 going again.

Some of you may remember a couple of years ago I posted some pics of my friends tractor and automobile graveyard. I called
![]() ![]() ![]() The engine is a 1968 K301 from a 123. It's just sitting in my frame until I can clean off my work table. According to Carl, it was running about 5 years ago before his brother died. He has pulled parts from it to repair others, but never started this one after he parked it. He also said that his brother rebuilt it about 2 years before he died. I'll pull the head and pan Monday to check it out, and hopefully have it running by the middle of next week. ![]()

The free engine wasn't so good after all. When I pulled the head and saw .020 stamped on the piston, I started to get worried. Normally I usually don't go over .010" without putting a sleeve in. The crankshaft had .030 stamped on it and the rod had been machined for inserts. The bearing inserts were badly worn. The crankshaft pin measured 1.468". There is also a crack in the rod cap through the drilled hole. I just put the head and pan back on. I'm really not comfortable trying to use it.
Carl had another K301 he said I could have if I would come take it out. It was out of a 124 with a burned wiring harness. Got it home about 3 this afternoon and mounted it on the engine stand. When I removed the head, there was no carbon build up and anti-seize on the head bolts. I believe it had been recently rebuilt. The rod looks new and the crank pin measures 1.499". The only problem is the balance gears. There is excessive end play and slack in both balance gears. When I removed the lower gear, I found the stub shaft badly worn. The only times I've ever pulled the gears before was on a complete overhaul. I had hoped there was a way to remove the upper gear without removing the crank, but haven't been able to find it. If anyone knows of a way let me know. Otherwise, I will pull the crank Monday to get the gear out. I really hope to have it running by next Wednesday. Cutting the yard with a push mower will probably kill me if I have to do it many more times.

Got the balance gears out and engine back together. The second "free" engine works great. Had to change out pto bearing and basket pulley. My son helped me put everything back together. We fabricated an electric lift from a used linear actuator. I got the actuator out of the trash. It was from a school bus recall. It operated the electric doors on the newer buses. It operates the box blade fine. Here are a few pics.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
