Just came from the dealer and talked to all the tech's with manual in hand . It was awesome they where very helpful. They have never worked on a B21 HST. They told me all the HST checks they have done they remove an allen plug and attach their gauges and move on. They all agreed that as the...

Thanks Rusty46 will do and I will let you know the out come.

I hear yeah and I will post the PSI readings when I get the test done by myself or when the service tech comes out to do it. Also the adapter for the test I believe is a spare Neutral Bypass Valve that is modified so a PSI line can be connected to it to get all the readings. (Low High Neutral)...

Called the dealer today at 1 because still no call back. She said both the manager and service tech for my machine were both at lunch. She took down my info and still no call back. Good thing I have another dealer close by.

Stopped by the dealer and talked to a tech who said I can get a fitting and hoses and gauges to do the check. Went to the hydraulic place and found out the threads on the relief valves are British 1/2-14. They made me a 0-5000 PSI test line for $56.00. Get home do the test according to the...

Shadow I was just saying what the manual says for inspection criteria. My rig is still together doing the troubleshooting.

The service manual says to" inspect the valve plates for wear and scratches, run finger across. If scratches are felt replace." No thickness parameters given.

Just looked at the parts list and found the Valve Plates that shadow mentioned. If it comes to replacing the HST I might just inspect everything and replace the plates.

85Hokie you can read my B21 HST problem thread below for the info. Basically the flow chart has you inspect the relief valves and do a psi check. if it passes the psi checks they say to replace the HST. If it does not pass, replace the relief valves. I don't want just replace all the relief...

Yes, the troubleshooting flow chart says to do the Check and High Pressure relief valve psi check. My problem is were do I get the fitting that that screws in the relief valve port for the check? The check should take 10 minutes tops with a piss break.

Yes the flakes / glitter was gold.

Is there a tech phone number I can call and speak to someone about my tractor? I'm frustrated as all get out. went to the dealer still no call back and shouldn't the service manager have some knowledge about equipment or are they just middle men that say bring it in. No disrespect to anyone just...

Thanks once again Wolfman. Went to the dealer and talked to the service rep and I am now waiting on a call after he talks to the lead tech on the floor about the fitting that screws into the Neutral relief valves that take a 27mm socket to remove on top of the HST unit to perform the check.

Received my Service manual and the flow chart says to do a (Check and High PSI relief valve) check. Very simple check if you have the Hydraulic Test Gauge kit. My question is can I just go get a metric fitting, some adapters, hoses and gauges and make my own or by a kit for my tractor. The...

Must be a Santa Fe thing. LOL My B21 is having HST problems also and I am waiting for my WSM (workshop service manual) from Alvin Equip.

Also Wolman, I put the rear up on jack stands and in HI @2200 rpm's jammed on the brakes and the engine bogged down with no slipping so I believe the clutch is doing it's job.

No PTO implements. The guy at the dealer showed me the HST troubleshooting flow chart from the WSM and after filter replacement I believe it was to check some relief valves. Looked at Illustrated parts book online and saw 4 P R valves on the HST unit. Thanks once again.

On my B21 it did the same thing intermittently some times I could hear it click when I turned the key sometimes it would take a minute to click. Thought it was the fuel stop solenoid. Found out the fuel stop relay was not getting power from the controller box. I would tap on the box and "Click"...

No it is in 2wd and the problem is the same in 4wd. And thank you for your assistance. Also the tractor rolls real easy in neutral.

Update. I replaced the trans filter and adjusted the clutch as per the owners manual with no big improvement. Cut open the filter and all was clean and now the fluid is at the proper level. On a flat surface in Low it moves fwd and rev fine but struggles and whines when driving back on to my...
