Powermaster 821 leaking

[Fred Bear]

I don稚 get why they would put a dipstick and a lever for the PTO in? Then fill it with fluid if none of it gets used.

I appreciate all the info so far happy Easter to everybody!

What powers the pump in the rear for the backhoe unit?

I have never seen a rig like yours and without more pics, I cannot tell. Someone else may chime in on that.
You can find these O rings no problem.

Fred,
My understanding is that the factory shipped a tractor like the 821 so that the hydraulics, and lift arms could be added by the dealer. In it's long life a previous owner may have filled the hyd sump, not knowing it wasn't used.

So technically i dont need new o rings if there doesn't need to be any fluid in that compartment?

 

[Dollar Bill]

The OEM would not have placed the O-rings there if not required.

Leak appears to be gear lube? If you leave the cover plate off, can you tell where is the leak coming from?

 

[Fred Bear]

Yeah it’s leaking out of the tubes.

Hi Fred,
2 new "O" rings and you should be all set.

Since you don't have the hydraulic pump that runs off the side of the engine the hydraulic cavity should be dry. If coming from the weep hole then possibly one of your tubes that run from the front plate thru the trans to the rear center housing is leaking. If leaking from the plate then try to replace the O rings. You can replace the lines that run thru the bellhousing or if you can find the leak in the bellhousing you could probably cut and can it off since you are not using the tractors hydraulics to run your loader/backhoe.
I knew a Fred Bear years ago. Bow and arrow guy, Any relation?

Since it appears you have a pto to run the backhoe pump there could have been fluid in the hydraulic chamber or the seal on the pto shaft could be leaking between the hydraulic chamber and the rear chamber. Try the O rings first, you might get lucky.

I took the cover off to see what was in there. 2 shafts one for rear end and one for pto pump that the backhoe is running off of I take it. I cleaned it up a bit. There are 2 holes and these holes lead to where my leak is where that cover plate is. The family farm and tsc didn’t have the rings I needed so I’ll go to the new holland dealer. My cover plate is bent and I don’t know if it’s supposed to be so I want to bring that into them too. There was a lot of condensation so I plan on filling the compartment agin once I replace orings

Got the o-rings $1.67 and flattened and cleaned up the cover plate.

Any leaks?

Good idea to add gear oil to the gear train compartment - The PTO shifter will appreciate the lube.

 

[Soundguy]

for sure. even on the machines with hyds delete, oil in the sump is good. and if a pto is present, it is needed for seal life between compartments.

All has been good with the 821. I had to get a new battery and coil. I cleaned the sediment bowl and replaced screen and gasket and notice my carb leaking from a jet by the bottom of the bowl. It just worked itself loose. Tightend that and has been good to go. Waiting on 60 tons of limestone for driveway now. Thanks for your help on this one I learned a lot about this machine the last 3 months.

Glad to hear of your success! Thanks for update.

Same machine, I have a new issue where it will run fine for 10 minutes then stall out. This is with it just sitting there not driving it. I put new spark plug wires on it but that didn't change anything. They needed it bad anyway existing ones where way weathered and loose fitting. New points and spark plugs installed last year. I believe I set them right last year?
