Connecting Hoses to the
Heat Exchanger

Drive Loop (from Heat Exchanger to Drive)

Depending on the location of the heat exchanger relative to the drive, the
following drive cooling loop hose kits are available:

Alternately, the following parts can be obtained from an appropriate supplier
to fabricate specific length hoses which must not exceed 9.1 m (30 ft.).

• 1-inch inside diameter hose Parker Hannifin p/n 801-16

• 1-inch swivel hose fitting female JIC (Joint Industrial Council) 37°

Parker Hannifin p/n 30682-16-16B

• 3/4-inch inside diameter hose Parker Hannifin p/n 801-12

• 3/4-inch swivel hose fitting female JIC (Joint Industrial Council) 37°

Parker Hannifin p/n 30682-12-12B

• 1-inch elbow Parker Hannifin p/n 16 CTX-B

To attach a coupling to a hose, lubricate the inside of the hose end with a
small amount of liquid soap. Set the coupling down on a solid surface and
push the hose onto the coupling — in one firm push — until the hose end is
flush against the plastic bushing on the coupling. Stopping before the hose
is fully on may make it difficult to push the hose completely onto the
coupling.

Connect the two drive cooling loop hoses from the heat exchanger to the
drive. Mating hose connections for the drive loop are shown in

Figure 1.3

and

Figure 1.4

. The mating process includes the following steps:

1. Assemble the mating version of the fitting (with swivel nut) to each drive

fluid fitting, and tighten to wrench resistance or 3.3 N-m (30 lb.-in.).
