Colt Case Ingersoll Garden Tractors

Thanks Eugen. I never saw the attachments link at the bottom of the page.

The beefier rear end was introduced on the 6XXB's to handle the weight of the backhoe. Three cast webs are the visual difference with earlier units having no webs. Backhoes with the 12" flotation tire kit have a unique axle lengths to extend into the 12" wide rim. These axles are longer than standard 4XX and 6XX series tractors. Silicon and a bent differential cover plate signal that this was another PO hack. I fully expected the diff to be full of water. The tube of silicon did the trick of sealing. It would have been nicer to find water in the case than finding no lubrication. Extreme wear in the axle bushings cause horizontal distortion in the differential halves, leading to a broken ring gear carrier. Tight tolerances in housing clearance make ring gear assembly hard to install. A break like this make removal a jigsaw puzzle.How long the tractor was driven without rear end lubrication? Pinion teeth are razor sharp. The drive motor will have to be removed for gear replacement. The left hand axle still had a seal and intact bushing.but the right hand axle seal was missing and the bushing was in 2 pieces. The right hand housing stub is worn obround where it became the carrier for the axle after the bushing cut through. The end may not hold a new bushing with out welding and machining the stub. Axles from other tractors are usually grooved by wear on the bushing surface but these appear to have survived running in a lack of oil and bushing. What the next step in the rebuild will be depends a bit on the housing condition. Probably mounting the transmission to the frame and fitting the backhoe supports will happen in spite of latest problems.

How could this tractor have been driven in this condition? Remember that the engine was missing the charging armature, the hoe supports were bent and the frame pulled apart. What kept this unit from getting a warm bath at Stelco is a statement of the previous owners tenacity.

That's quite some damage there. Hopefully the case is in good enough shape to not need replacement. Fingers crossed!

Is the gear assembly the same as a 4xx? My logic says not.

Wow Spike, as long as it moved, the PO must have just kept abusing it.

Day 3 is the first full day (11 hours) of the parts swap onto the new frame. The first 2 days were about 5 hours each. Inspection of the flotation axle housing was good. There is a slight casting chip on a stub end and the damage from failed bushings proved to be limited.Flattening a the end of a 2 foot long 1" pipe seemed to be a bit of over kill for a 1/2" wrench but some have said the motor bolts need a lot of force to remove. They are correct but the little wrench took the abuse like a champ.With the motor removed from the transmission case, the gears slid off and the case became lighter to handle. After mounting the case to the new frame, the rear backhoe mounting support was installed. This is not the first time I have encountered accessory mounting holes in the casting rusted to the point of stripping. These holes will have to be repaired before painting and assembly. The next 4 hours was spent correcting and reforming the lower hoe support arms. The lower arm offsets had bend damage and holes were off by a 1/2 inch so the counter balance weights would not fit.Multiple trips to the 20 ton shop press along with eyeballing the angles and parallelism eventually lined up the counter balance weight holes. The front frame hangers were off about 1/4" from where the optimum location need to be. Cutting the ears off off of the lower arms and welding them in the prime spot solved that issue. Note the 2 short arms are the upper links and are beyond repair and will be replaced. The lower arms need attachment points fabricated for attaching the short arms to. The previous owner flame cut them off and blew out the mounting holes. Those holes will be weld filled and re-drilled.After attaching the carrier to the frame the front carrier support brackets could be lined up then the frame drilled for final attachment.The rest of the day was spent sorting through spare parts to find the best spindles and steering gear. Paint is a novel way of shimming to take the slack out of front axle steering instead of replacing the bushing. All decals have been photographed and removed before sending parts out for blasting. A source for Davis backhoe decals will be helpful.The last project for the day was to knock the tires off of the rims. With that all that was left to do was cleanup the work area. Tomorrow afternoon will be spent replacing the water pump in the Nissan forklift. The pump locked up and the forklift is my much needed other tractor.

Dropped the last parts off on Monday expecting a long wait for blasting and priming. Call came in late Wednesday afternoon that everything was ready for pickup. Finding space for everything indoors was not on the agenda for today but it looked like rain was coming so we made room.

The snag of the week, a Kijiji barn find. 4 Goodyear Terra Tire 26X12-12 8 ply tires. I had to take all 4 and only need 2. These tires have never been mounted.

what a great find! What will you mount them on?

Looks like you're set on the tire front for a little while. nice find.

Eugen these are the exact replacement tire for the 600 series backhoe equipped with the flotation tire kit. I had been hunting for a Canadian supplier of 8 ply tires for a week. Only one place called back with a 6ply offshore and no specific delivery date for $360 each. Yesterday I did a kijiji search and these came up 15 minutes from me.
