Zetor 5211

Brakes are completely non-functional, described as common issue on this model. Requires rear end disassembly for repair.

Charging system does not function. Only starter and oil pressure light operate. Alternator or voltage regulator malfunction.

A roughly 1977 production Zetor that got retrofitted with a front loader and backhoe attachment around 1983. Backhoe mounting frame is for a different model tractor, so they modified it with a bunch of crappy welds and rusty rebar. Somehow, that hasn't broken yet. Brakes are dead, as is common on these, but I was able to get parts and will be tearing apart the rear end to fix. Electrics also need debugging, the only things that work so far are the starter and the oil pressure light. Doesn't charge. But it does start and run.

TLDR: How to fix clutch with no resistance in Zetor 5245? My wonderful elderly neighbor has a Zetor 5245. This year he started it up and, when pressed, the clutch just went straight to the floor. No resistance, nothing happens. He's at a loss, the nearest dealership is 4+ hours away, and money is tight for him. I'd like to help him fix it. I have a little experience working on boat motors, including a Cat 3208, and am relatively handy but completely new to tractors. It looks like a hydraulic cylinder attached to the clutch. It feels like there's no fluid in the cylinder. The tractor was low on hydraulic fluid; I added about 2.5 gallons to bring it up to between the middle and high hydraulic dipstick markings. The user's manual mentions a bleed screw for the clutch but the 1980s diagram is difficult to interpret, much less even find the parts referenced in it. The tractor fires up without hesitation and the bucket will move as intended. If anyone can offer any advice, pointers, links, or even just general knowledge of how the system works I'd appreciate it. Thanks in advance. ​

As the title suggests, the fan won't move and we think it's a water pump issue but we're not completely sure. Everything else works fine but the fan won't spin. I'm not a tractor guy or particularly knowledgeable when it comes to em so any form of help is appreciated. BTW all that white stuff is snow. Also. Anyone got an idea on how to remove the bar in the second Pic?. The bolt you see is stuck and we have tried holding the bar with wrenches and stuff but it did not work.
