Green Case Loader

[Harry]

Been working on the mini loader a bit. I removed tge lovejoy coupler from the engine crank. It was securely in place so no problem there. The pump is another story. It appears that the engine has to be moved forward to give me enough room to get my hands on the coupler half. Many things had to be taken off to move the engine forward. Engine oil drain pipe goes through frame so draining engine oil. It just takes time to make it happen. Harry

I removed the drain pipe from the engine and got the engine to move forward. This has left room to work on the pump lovejoy coupling. I tried yesterday to put a puller on the coupling under the pump support but not enough room to get puller around coupling. Then I tried to put a larger puller around the pump support and slide the coupler and the pump support off together. No luck puller arms were to short to fit around pump support. I was trying to get this off without draining the oil and removing the pump. If the pump is bad I’ll have to remove it anyways. Any suggestions on removing the coupling off the pump shaft? Harry

@Harry pulling the pump is not a pleasant job but you are almost there. The pump condition is suspect given the symptoms you described. I would pull it and bench test it at this point. Looking back on the first 646 restoration, it would have paid a lot of peace of mind after the fact. I didn't dig deep enough and am left wondering if I have pump or motor issues.

Spike, thanks for the suggestion bench testing the pump. I don’t have the equipment for doing that and maybe just replace the pump. Harry

Harry, even just opening up the gear pump and looking for excessive wear would be a good use of time Gear Pumps are a pretty basic design with not too many moving parts - looking for wear and/or cavitation should be pretty straightforward...

I’ve never taken one of these gear pimps apart to look inside, but this one will be my first to do so.

When I got the Case 224 the pump was bad. So I got another pump and put it on. Luckly for me it worked and lucky for me it’s still working after two mishaps with the pto lever. , any way, I took the non working pump apart. All chewed up inside. So no good.

Thanks for your insight Noel. I’ve had a few gear oil pumps apart that were on V8 Chevy’s but not any GT ones. It will be a learning experience for me. Harry

Jumped into the dirty work today. Removed parts I didn’t want to but had to remove the pump. Lovejoy was secure on pump shaft, so it appears I’ll take it apart to check for wear. Harry

Lots of fun Harry.
