TANDEM PUMP REPLACEMENT 2.10
IMPORTANT
When making repairs to the hydraulic system, keep
the work area and parts clean. Use caps and plugs
on all open line and ports.
Upon reassembly, inspect the outside area of the tandem
pump housing for damage that may have occurred in tran-
sit or handling.
1 Attach a lifting device to the tandem pump.
2 Install the pintle levers onto the pump, grease the
rear spline.
3 Place the pump into the loader, slide the u-joint onto
the spline while guiding the pump into it’s mounting loca-
tion. Insert mounting bolts and tighten to 20-25 ftlbs
torque. Remove lifting device.
5 Install the fittings removed from the old pump into
the new pump. Reconnect the hoses.(fig. 4838 page 2-4)
Torque the fittings and hoses according to Torque Chart
in Section 2.13 page 2.53.
6 Before connecting drain tubing,(fig. C5207a) fill
pump case with hydraulic oil.
7 Install brake shaft and switch mount. Adjust switch
mount so that switches make contact with brake shaft
when the restraint bar is down. Check to make sure
switches are closed.
When the restraint bar is up, there should be a gap
between the switches and the brake bar. The switches
should now be open. (C5207b)
8 Install the control lever linkages and the limiter bar.
9 Follow the start-up procedure in section 2-8 for prop-
er start-up with a new pump.

Adjustment and Limiter adjustment.
