@Eugen Good to know you haven't lost your sense of humour and you can still kid with us about your struggles... :rofl:

I was just going back through my photos to refresh my memory of pulling the Hyd. pump - and there aren't any of the actual removal - I almost thought I had dreamed the whole experience

(But I didn't)

I usually take lots of cellphone photos as I'm starting a job - makes it so much easier to put things back together in the right place - I think the 530CK has a slightly smaller pump, but remember draining the Hyd. oil and removing all the hoses from the pump before it would move (they might even have been original ones - they were really hard and wanted to crack if moved to much) The suction hose did get replaced...

When you get this tractor all sorted out and using it you’ll be smiling from ear to ear. Your on the road to success! :peace: Harry

@RoamingGnome it's useful to learn what you've done. One thing I dread is draining the hydraulic fluid, I don't even have clean pails and to buy new fluid for this tractor would probably be a few hundreds. When I got the tractor it about half empty, so I already put three pails of new hydraulic fluid in. Unless really necessary, I try to avoid it.

Had another good look at it today (it's different in daylight) and came up with a plan. Basically I noticed that "nose" of the tractor is like an upside down letter U made of 3/8 heavy plate, and about 16" long. The radiator is bolted to it on the inside. It is bolted on the lower frame with 3/4" bolts. In the picture below I circled the four bolts in green.

My plan was to undo those bolts and lift the whole thing up thus making room above the hydraulic pump to lift the engine from below. Those four bolts were a pain to undo. Real tight they were, and some of them no leverage on the wrench because of the tight space. The battle with these bolts was about two hours.

Now, how to lift that? Maybe the 644 would do. Created a boom of sorts from a good piece of lumber and chained it to the top of the frame.

Was able to lift it about four inches, high enough to put some pieces of wood in there to keep it in position. I had to undo the front little radiator that's bolted to the big one in the back, because the hoses that came to this one were hooked on steel pipes.

I don't have pictures of the next move, but I proceeded to lift the engine from below, with the jack on wood and steel plate. However, i can find no spot to put big wood under, or steel, so it doesn't stay on the jack. I don't trust just the jack there.

I've been also thinking of creating an extension to my electric wrench so I don't put my hand anywhere in between there. Just don't want to risk. To be continued...

Harry, I hope to get to that point, and if so, you're right, it'll be a big smile. :)

@Eugen Looks like you are making good methodical progress... one bolt at a time, so to speak. Love your "good piece of lumber" - Wish I was closer :wave2:

I'll have to do some more googling to check similarities / differences between our two backhoes. Things were a little more primitive when mine rolled off the assembly line in 1965. On the 530CK I had no choice - you have to remove the pump to change the fan belt - perhaps a local garage or shop might have a few buckets to spare? Waiting for the next instalment of your adventures... :42:

The oil pan bolts were easy to come out. Well, easier with the cordless ratchet.

But it looks like the engine needs to go up more for the oil pan to come out. :hm:
