I think I'm wrapping up the PTO and 3 point conversion on my CASE 420B. It was originally a loader/backhoe tractor with no PTO or 3 point hitch. I found a 500/600B as a donor and all looked as they would be direct changovers, but the PTO shaft was 3 inches longer and had to be shortened, the Eagle Hitch had the same bolt pattern but wouldn't fit on top of the trans case without hitting the bull gears. I had to fabricate a riser in order to use it. There were no places for the lift arms so I drilled and tapped the casing at the bottom with 3/4-10 thread to fasten the lift arms. When I fired it back up the cooling line for the CASE-O-MATIC sprung a leak. Apparently it had rubbed through the wall of the steel tubing at the corner of the bell housing. Moving the stuff around apparently broke through thinnned area. Tonight I had to splice the line to remove the leaky section. I also, found that the Eagle hitch has the creeps. When the lever is in the neutral postion, the lift arms will slowly rise. If I press the lever downward slightly the lift will lower. I'm afraid the spool valve is leaking past the seals and filling the lift cylinder. The gas tank didn't fit after adding the plate with valves for the lift and hydraulic outlets. I had to fabricate new brackets for it. After putting on the finishing touches, I'll degrease it and paint it. The power steering cylinder is leaking and no longer available from CASE. When I refilled the transmission, the right pinion seal is leaking onto the brake linings. With the raised rockshaft housing to miss the bull gears, the seat is now too high. My feet barely touch the fabricated running boards that were missing. With the weight of the loader and backhoe gone the Case-O-matic lurches very badly and can't get it to smoothly engage. I'm wondering if it's worth all the trouble.
