4-14. HOSE REEL ASSEMBLY - Continued
Ground motor lead marked (-) to frame using screw and nut (14).
Install motor lead marked (+) to solenoid (15). Be sure both motor leads are securely attached.
Partially reel out the hose. Press rewind button and observe the chain drive if chain jumps on
motor sprocket it is too loose. If the motor is slow and noisy the chain is too tight. Readjust tension
Reel Drive Chain Replacement.
Loosen reel motor mounting bolts and nuts (9), and disconnect chain connecting link (8).
Remove old chain (2) from motor and hose reel sprockets and install new chain.
Push motor toward hose reel as necessary and install new chain connecting link (8).
Move motor forward until chain is properly tensioned (1/2 in. (13 mm) deflection midway between reel
and motor sprockets) Tighten bolts and locknuts (9) to 20 ft lb (25 Nm).
Partially reel out the hose. Press rewind button and observe the chain drive. If chain jumps on

Hose Reel Piping Replacement.
To replace hose (3), between discharge manifold and hose reel, the hose body heat shield
must be removed, see para. 4-11.3.
To replace hose (3), disconnect it from elbow assembly (4) and valve on pump body discharge
manifold. Pull hose past water tank and remove it from truck.
Hose (16) is manufactured from one piece of hose, and two swivel fittings. P/n 4110245.
Route new hose (3) alongside water tank and connect it to valve on discharge manifold and
elbow assembly (4) at hose reel.
Other hose reel piping components may be replaced individually as required. Apply pipe sealant (Item
22, Appendix E) to all pipe thread connections before assembly.
