Installation Instructions

 CAUTION!

Risk of a hazardous situation if kit is installed 

improperly or modifi ed in any way. Damage to 

the machine could result. Read and follow all 

installation and setup instructions. 

W091

Tractors without rear hydraulics available for implements 
require a PTO-driven pump kit. The tractor must have a 
1-3/8", 6-spline PTO shaft to fit the pump drive coupler. Shaft 
adapters cannot be used, and the tractor cannot operate at 
any speed other than 540 rpm.

IMPORTANT!  Installing Wallenstein backhoes on tractors 
with a variable speed PTO is not recommended. Operating 
at speeds higher than 540 rpm can overspeed the pump and 
cause early failures.

Make sure pump kit is matched to your backhoe model.

Both PTO Hydraulic Pump Kits install in the same way for all 
models. Installation and setup instructions apply to both kits 
unless specified. 

Please follow this instruction carefully.

The PTO Hydraulic Pump Kit comes partially assembled. 
Illustrations show typical assembly. This assembly procedure is 
one time only. Once assembled only regular maintenance and 
minor adjustments are required. 

Tighten all hardware using the Bolt Torque table on page 12. 
Tighten all hydraulic connections using the Hydraulic Fitting 
Torque table on page 13.

Preparation

• 

Basic shop tools are required, including 9/16" wrenches 
and sockets, thread sealant.

• 

Dexron® III Automatic Transmission Fluid (ATF) is used as 
hydraulic fluid in this system. Dexron VI or Mercon® ATF 
are also acceptable substitutions. See capacities noted 
above. 

• 

Make sure the tractor and the area around it is clean and 
free of debris. Park on dry, level ground with the brake 
applied and the engine shut off. 

• 

Leave backhoe on the shipping skid.
