FLOW DIVIDER KIT (Optional)
General Description
The Flow Divider Kit consists of those parts required
to power the backhoe from tractors or skid steer
loaders that have hydraulic flow rates above 12 gal-
lons per minute (gpm). It includes the flow divider
valve, hydraulic hoses to connect the valve to the
backhoe, and adapter fittings. This kit does not
include the hoses required to connect the flow
divider valve to the tractor or skid steer loader.
These hoses may be obtained from your local deal-
ership and must have 7/8” - 14 JIC (37°flare) female
threads to connect to the flow divider valve.
NOTE -
Tighten all hardware to the torque require-
ments specified in the torque chart.
Assembly
IMPORTANT - If hoses are hooked-up incorrectly,
serious damage to the backhoe valve will result.
DO NOT use thread sealant on union ends of
adapters. DO NOT over-tighten fittings - they can
split or expand causing hydraulic fluid leakage.
Backhoe Mounted to Tractor
1. Assemble three 90° male adapters (10) to flow
divider valve as shown in Figure 25.
2. Assemble flow divider valve (5) to backhoe -
mount valve to inside face of right hand side plate
using 5/16” x 2-1/2” bolts (1) and lock nuts (3).
Orient valve so that wording on valve can be read
after valve is mounted to backhoe.
3. Assemble JIC swivel run tee (9) to proper port on
flow divider valve according to instructions that
follow.
Tractors with an auxiliary hydraulic flow of 15
gpm or less
Connect JIC swivel run tee (9) to 90° male adapter
(10) on “K3” port on valve as shown in Figure 26.
