I have been able to remove pump and found a large washer just floating in cavity. Is it supposed to be secured? Also there is a recess on one side which way does it go? I was experiencing almost zero lift.
Need help B8200 hydrolic pump

Which cavity? Did you do any diagnostics before pulling the pump? Pictures of your parts is always gelpful.

I assume that “washer” is really the remnants of the seal on the pump shaft. Your engine oil level may be high from the pump adding hydraulic oil into the engine crankcase. If so you should change engine oil and filter, and possibly add some fluid to the transmission case to refill it.
Here is a parts diagram with the shaft seal part number. If that is the “washer“ then install a new seal.

Are you actually talking about the drive?
This collar / washer was behind the gear 17 when you pulled it apart.
And the grove goes towards the gear.

Here the washer. It fell out when I pulled pump off. Not sure which way the recess went. Is it remnants of a seal?

That is NOT the seal (as far as I know!). See post #4 that is probably closer to what it is.
It looks like someone has taken the drive apart and put it together incorrectly.
@North Idaho Wolfman will probably be along and give you a more definitive answer.

I suspect thats the bearing retainer. Consult your workshop manual.
I will ask one more time - what hydraulic diagnostics have you done and why remove the pump?

Once the retainer's back in groove side to the bearing like Wolfman said, I'd get a baseline before chasing anything else. Clean the suction screen, top off the fluid, then throw a gauge on it and see what the relief hits with the 3-point at full lift. That one number tells you a lot. If the pressure's good and it still won't lift, I'd look at the lift cylinder or the control valve. If it's low with a healthy pump, the relief setting is usually your culprit. I use a gauge for this and it saves a lot of guessing. Let us know what it reads.

The pressure test is an excellent idea.
On that tractor the best test point for pump discharge pressure is the AUX hydraulic outlet block. Connect your gauge directly to the OUT port and turn the selector valve to the AUX position. That will deadhead the pump against the he gauge. Start the engine and set engine speed to max RPM. A low pressure result indicates a pump or tractor side relief valve priblem. If low pressure is found more testing is needed to identify pump or relief vakve problem.

Good call, Dan. The AUX OUT port is the easiest place to tee in on that tractor. Hoping the OP posts a number so we can tell if it's the pump or the relief.
