PTO PUMP KITS (Optional)

General Description

The PTO Pump Kits consist of those parts required to power the backhoe from the tractor’s PTO shaft. They include the PTO pump (6 or 8 gpm) and adapter, reservoir, filtration system, hydraulic hoses, and fittings. In addition, they include a torque plate that straddles the tractor’s draw bar and keeps the pump from turning with the PTO shaft.

NOTE - The speed of backhoe operations increases as PTO speed increases.

ASSEMBLY

IMPORTANT - When installing fittings, always use a paste-type thread sealant on perrmanent connections such as NPT (pipe) threads. DO NOT use Teflon tape as thread sealant. DO NOT use thread sealant on union ends of adapters. DO NOT over-tighten fittings - they can split or expand causing hydraulic fluid leakage.

Please refer to Figure 18 as a guide for assembly of the PTO Pump Kits.

1.Assemble reservoir (16) to backhoe using 3/8” x 1” bolts (2), flat washers (5), lock washers (7), and hex nuts (10).

2.Assemble 1” street elbow (34) to fill port on top of reservoir, orienting elbow so that it faces right rear of backhoe. Connect fill tube (17) to street elbow.

Elbow may have to be rotated slightly to allow fill tube to be installed so that its open end is located just behind foot platform to right of operator’s seat tower. Install breather cap with dipstick (18) onto fill tube.

3.If filter element (35) is not already attached to filter base, apply a thin layer of hydraulic fluid to the rub- ber seal on the filter element and then screw it onto the filter base. Hand tighten the element until it just seats on the filter base, then tighten an additional 3/4 of a turn. Use this same procedure when replac- ing filter element.

NOTE - Change filter element every time oil is changed.

4.Assemble 90° adapter fitting (27) to inlet port of fil- ter base and orient so that free end of fitting will point towards backhoe and angled slightly down- ward from horizontal. Assemble small 90° beaded tube fitting (26) to outlet port of filter base and orient so that free end of fitting will point towards backhoe and angled about 30° upward from horizontal. Connect filter assembly (15) to left rear corner of backhoe foot platform using 1/4” x 3/4” bolts (1), flat washers (4), and lock washers (6) - flow direction arrow on filter base should point toward rear of back- hoe. DO NOT over-tighten bolts as this will strip the threads on filter base.

5.Assemble on 90° JIC adapter fitting (28) to “Out/Return” port of bulkhead connection and an
