1978ish B7100. Rear lift seems to have gotten weak. So I removed the bolt which appears to be the 3 point oil filter part #66611-36120 but there is no screen. So is it possible it fell off? Would that contribute to 3 point losing power?
Kubota B7100 3 point ?

The part number has changed.
It is more likely that if your hydraulic system has been running without a screen, the pump has been ingesting small particles leading to accelerated wear.
Is the loader powered by the main hydraulic pump or does it have an independent pump driven from the front of the engine crankshaft?
Which transmission does your tractor have?

Main hydraulic pump. The front end loader has its own which is run off the front
You feel the 3 pt is weak. Will it hold a load in an elevated position for some time. This to determine the condition of the 3 pt piston seals.
If a load drops quickly on the 3 pt hitch, leaking piston seals would be the first repair to try.
Invest in a 0-3000 psi pressure gauge for $15 + a few $ for some fittings.

Only with real pressure readings can you assess the condition of the pump.
HST or manual transmission?

Manual transmission. Once I get my solenoid I’ll start it up and get specific info. I believe it got weak because I could not lift my trailer with the hitch ball I attached to scraper like it used to It does lift scraper. As far as that screen should I not worry about it ? Or attempt to take apart and remove. I will order a new filter and change hydraulic oil.
As far as the piece of missing screen/filter, really you have no idea if it is inside and even if it is, up to now it has not caused any issues so I would install a new one and continue to use the tractor.
Will the scraper stay in the elevated/up position with the tractor off?
Dave
Does the B7100 have this screen? I thought only the HST models do. I havent had my B7500D for long, but I think only the HST's have that screen, not the manuals.

They all have the suction screen, manual trans or HST. The pump suction is located low in the transmission so it does not suck air.
Dave
Good to know, thank you. Gotta look back and see what if I cleaned/replaced mine when I got the tractor.
