Bomag diesel plate pr65/52d will not go into reverse??

[RickT73]

hello looking for input i have an 04 Bomag diesel plate PR 65/52D-3 pick up at an auction faily cheap Runs great But will only go forward .
it has the thumb forward and reverse switch so far this is what i have checked hydraulic fluid ok, loosened the fittings at thumb control under switch seams to be getting fluid , took body control switch off and inspected it put 4lb air and worked switches seems to be functional not sure which is pressure but seams to be going thru the other ports ??
i've used it once to compact a footing just forward and would like to get the reverse fixed if possible.
any knowledge is appreciated

Welcome to HEF Rick!

What is the machine's serial number?

oosened the fittings at thumb control under switch seams to be getting fluid

But can it build pressure?

101 690 31 1431 i assume says No# after type
has pressure on hydraulic pump side to handle have not put a gauge on it but its enough i close it right away.my understanding is one shaft is driven by belt spins both dampers and has hydraulic pump on opposite side of shaft which goes to handle which feeds the other side pump for directional!?

Don't remember exactly. Couldn't find a service manual, but did find the operation and maintenance manual. Check your messages.
