I drained fluid again and replaced o-rings #8 and hose #3. Strainer was clean this time but did spray with brake cleaner and used air to blow out. Still no lift. The pump sounds like its cavetating. Will replace o-rings #6next.

While you are changing the o-rings you can also ”prime the pump” by putting some hydraulic fluid into the top opening of the pump. I would recommend leaving the banjo bolt out and pouring oil through the opening in the tube marked #1 where the bolt is installed.
The oil may drain down slowly since the oil level might be below that level. The coating of oil on the gear teeth in the still help the pump pull oil into the pump. But I would try to start the tractor soon after you get it back together to give it the best chance of pulling fluid.

A gear pump is self priming once filled with oil. If it loses prime after sitting its defective.

But it also won’t hurt anything and could possibly help if it has sat static for a long time with low oil level.
Well I've done all of the above still no lift. The pump will growl for a second or two and the lift will raise an inch when that happens then nothing for 5-10 seconds then it growls again for a second or two and the lift raises. It will continue this until the lift is all the way up. The growling continues in the same way when completely raised. Lift drops normal when put in lowering position then when put back in raise the same happens. ?????
This is a very simple circuit.
Have you checked for oil at the outlet block?
Have you verified the directional vslve on the outlet block is in the correct position?

Yes. I removed the "A" port and started the engine and a gush of fluid maybe a 1/2 cup came out then nothing. Shut engine off and repeated with same results.
I agree it looks simple and there's some little something I'm over looking but can't put a finger on it.
It acts like its sucking air from some where. Probably just gonna get a pump kit, o-rings and seals, and rebuild it. I found out the lift has been inoperable for about a year. It has a finish mower on back and thats all its been used for all its life. Its a bushhog brand finish mower not brush cutter.
Where do I find the serial number on this B8200E. I have found the metal plate thats attached on drive side of transmission housing but it doesn't have the serial# on it. It's a 1986 year.
A pump kit is not going to fix your problem. If its bad you need a new pump.
Do a little diagnosis before throwing money at it.
Remove the hose clamps (4) and rubber connector (3) on the suction line and drain the oil into a bucket. Start the tractor and use your thumb to test for vacuum on the suction pipe

If you do feel suction and want to be sure the pump will pump from a bucket to bypass the tractor intake piping you can see this thread for a description of how to use PVC pipe as an intake into the rubber hose. (The pictures are now missing). This was set up to suck oil out of a bucket and dump it out of the transmission drain. But you could remove the connection at your test point A (port “A” as you called it above) and catch the fluid from there.
If the pump is working properly it will pump several GALLONS PER MINUTE so don’t run it for very long or you will run the bucket dry and damage the pump.

I have an B8200 with a standard, somehow water got in, I think through the gear lever boot. After going through two drums of oil and two drain and refills with no noticeable difference I realized that the hydraulic pump and hydraulics were obviously still contaminated. Even buying cheapo...

Thank you sir. Yes I want to make sure whats wrong. Don't want to buy when I don't need to. I'll try this.

Thanks everyone for the help. After cleaning the strainer 5 times I have lift.
Only problem now is no charging. Any trouble shooting tips greatly appreciated.

Glad you got it operating. You may want to replace the strainer with a new one in the future.
As I understand it your tractor has a dynamo and a regulator. The dynamo can be tested.
See this thread for details about dynamo and testing it (If it has two wires). If it has three wires then post back

b1500dt where is alternator
alternator/charge warning light stays on for a long time.

Mine is different from that one. I do have a dynamo but its in like an alternator not like the picks in the link. Mine has a water pump also, The dynamo on mine has two wires and as I was testing it showed 30amp ac at 2600-2700 RPM. Is the regulator testable or is it to be replaced when dynamo testes good?Glad you got it operating. You may want to replace the strainer with a new one in the future.
