do not know what that is
Technician: JON, Small Engine Technician replied 4 months ago

YOU WILL HAVE A ROD ON BOTH SIDES THAT ACTUALLY DISENGAGE THE DRIVE SYSTEM. THEY NEED TO BE PUSHED ALL THE WAY INWARDS

got it from a husqvarna dealer
Technician: JON, Small Engine Technician replied 4 months ago

okay, just wanted to double check the part number was correct.

being that both sides are not working, the issue will be in the belt tensioner area I would believe. how is the tension on the belt ?

pump motors are separate, so it seems like a tensioner spring or something is missing to tighten the belt once the arms are engaged to move machine

Ask Your Own Small Engine Question
Technician: JON, Small Engine Technician replied 4 months ago

YOU SHOULD HAVE A SPRING ( part number 532 19 61-05)

this keeps tension on the drive belt. it mounts from the tensioner pulley bolt to the frame.

belt has alot of tension on it spring is fine
Technician: JON, Small Engine Technician replied 4 months ago

I will OPT OUT and see if another expert may be able to assist then. I am at a loss. unheard of for both pumps to fail at the same time.

if spring is good, and belt is tight. bypass valves are pushed inwards, only other thing I can think of is the smaller drive pulley above the clutch is smooth and needs replaced

Both transmissions run off of the same drive belt. The only reason both transmissions will quit, is a problem with the belt or idler. Are the two top transmission pulleys turning when the engine is running? Is this the belt that was replaced? Or was the deck belt. the lower belt replaced?

The drive belt was replaced
Technician: Curtis B., Technician replied 4 months ago

Are the two upper pulleys on the transmissions turning when engine is running??

Ask Your Own Small Engine Question
Technician: Curtis B., Technician replied 4 months ago

If the upper pulleys are NOT turning, and the belt is tight, the engine pulley would be loose on the crankshaft.

I see the question is still open, did you find the problem?
