Zero Turn transaxle oil change air not purging SOLVED!

[RMR]

I'm working on a Hustler Fastrak SD 928374 with Hydrogear transaxles. I replaced the o-rings on the oil pumps as well as a fluid and filter change. I purged the pumps using the hydrogear method. The left axle works perfect but for the life of me, I can't get the right side to build any power. I've purged and purged and purged. The best I've gotten is the drive works off the ground at half throttle or less. As soon as I run the throttle up, it loses what little power it has and the wheel stops turning. Both forward and reverse is equally weak. Is there a trick to getting out stubborn air pockets? Or is there something else causing the issue? It worked just fine before the fluid change.

Thanks

May already too low on oil, recheck oil level is one thought.

It's got plenty of oil. both axles use one oil tank and it is topped off.

Then you may an air pocket in the supply line. Try bypassing it; check and fill the transaxle directly.

Problem solved! I found it. I put the oil pump cover on backwards. I've done dozens of these and never knew they were directional and for reasons unknown I have gotten lucky every seal change up until now.

Thanks for confessing. Now we know to watch for that.

Well thanking for letting us know happen. Apparently Murphy don't visit you much but I wish he would me alone.

I'll put a note in my copy of the service manual for future reference.

I did find a note in the service manual about marking and aligning up the reference marks. Also has a square direction mark as note in the following image.

And we collectively do the happy dance !!
I swear, I have run into more silly basic things lately that required the help from the guys here. I don't know what's happening but my wife asked if her hair looked alright. I said " You look great Jill"....she said "My name is Tami...."

But at least you still got that shirt with "BOB" don't you so you can remember your name?

Unless you think "BYOB" is just a typo....
