SECTION 1 — GENERAL INFORMATION

1.1 INTRODUCTION

This instruction manual contains installation, operation, maintenance, and parts list informa-

tion for DuraClass Model 1715 PL and Model 1721 PL conversion hoists.

1.2 GENERAL INFORMATION

These are twin arm type hoists and are designed for use with wood or steel platform bodies.

The 1715PL hoist is used with bodies from 10' (3.048 m) to 15' (4.572 m) long, and the 1721

PL hoist is used with bodies 11' (3.353 m) to 17' (5.182 m) long. These are for single axle

chassis installations and the dumping angle is 45°.

1.3 HOIST CAPACITY

Lifting capacity depends on the body length and the overhang beyond the rear hinge. The

capacities for each model hoist and the recommended body lengths are charted in Figure 1.

SECTION 1 - GENERAL INFORMATION

Above capacities are based on mounting body with 3" (76 mm) clearance be-

tween front of body and back of cab, and hinge location 32" (813 mm) behind

centerline of rear axle for 1715PL hoist and 33-1/8" (841 mm) for 1721PL hoist.

Also assumes level loading, with center of gravity at midpoint of body.

SECTION 2 — INSTALLATION INSTRUCTIONS

Refer to mounting drawing 701D3499 for the 1715PL hoist and 701D3501 for the 1721PL hoist and

perform the following.

REVIEW MANUAL BEFORE STARTING INSTALLATION.

STUDY THE JOB CAREFULLY TO DETERMINE ALL OF THE

HAZARDS PRESENT AND SEE THAT ALL NECESSARY

SAFEGUARDS OR SAFETY DEVICES ARE PROVIDED TO

PROTECT ALL PERSONNEL AND EQUIPMENT INVOLVED.

1.1 HOIST AND SPACER PADS

Remove body from chassis. Cut off end of chassis rails as shown and locate hoist frame square

on chassis and with hinge apron tight against end of chassis. Cut off front en dof hoist frame, if

necesary, to hold 3” (76.20 mm) clearance between frame and back of cab.

Locate spacer pads as shown; drill holes in pads to clear rivets, and weld pads to hoist frame.

Locate hold downs and drill holes in chassis for snug t of bolts.

2.2 POWER TAKE-OFF, PUMP AND DRIVE LINE

Select the correct power take-off to match truck transmission. The PTO output shaft should run at

45 to 65 percent of engine speed. Mount PTO according to manufacturer’s recommendation.

Bolt pump to hoist frame as shown and install drive shaft from PTO to pump. The centerline to

centerline of front and rear 80” (2032 mm). Cut drive shafts to the proper length to have maximum

engagement in universal joints. Hand grease end of drive shaft and slip joint before installing. Max-

imum angle on drive line shafts not to exceed 10°. See Figure 2 for installation recommendations.

2.3 CONTROLS

Lever controls are standard and should be mounted on the oor of the cab convenient to operator.

See control installation drawing.

2.4 PIPING AND FILLING SYSTEM

Connect piping from pump to cylinder as shown. Use a thread sealing compound on all pipe

threads.

Remove piping from pump to cylinder as shown. Use a thread sealing compound on all pipe

threads.

Remove vent plug at top of cylinder and ll with oil (See Section 4.5 for proper oil). Replace plug.

CAUTION

SECTION 2 — INSTALLATION INSTRUCTIONS

2.5 REMOUNT BODY AND BODY GUIDES

Install Z Iongmembers. Cut off front of longmemeber, if necessary, to hold 3” (76.20 mm)

clearance between longmember and back of cab. Mount Iongmembers to outside (as shown),

if possible. If longmember are mounted to inside, hinges must be shimmed so that side move-

ment of long members is restricted to 1/8” (3.04 mm). Install grease ttings in hinges.

Install crosshead shaft through pick up plates of longmembers and upper end of links. Bolt in

place.

Remount body so that it is square on the chassis, has the proper cab clearance and ts

snugly into Z longmembers. If wood longmembers on body, bolt to Z longmembers with 1/ 2”

(12.70 mm) carriage bolts (not furnished). If steel longmembers, bolt to Z longmembers with

1/2” (12.70 mm) capscrews (not furnished), or weld body longmember to Z longmembers.

Locate body guides at a convenient location close to cylinder trunnion. Drill (4) 41/64” (16.25

mm) holes in chassis rail, using holes in body guide as a template. Bolt in place.

2.6 VENTING OF SYSTEM

WHEN ANY WORK IS TO BE DONE ON BODY OR HOIST AND

BODY IS FULLY OR PARTLY RAISED, IT MUST BE BLOCKED

SECURELY SO IT CANNOT FALL. IN ADDITION, DISENGAGE

THE PTO AT SUCH TIME.

READ AND STUDY OPERATION SECTION OF ANUAL BEFORE

PROCEEDING.

Raise body slowly until cylinder is fully extended and block body securely. Remove vent plug from

top of cylinder and rell cylinder if necessary. Raise and lower the body several times until air is

eliminated from the system. Recheck oil, observing Warning precautions. With body raised the

oil level should be 2" (50.80 mm) to 3" (76.20 mm) below the ll hole in the cylinder. Add oil, if

necessary. Replace vent plug.

Keep dirt out of system.

2.7 DECALS

Place WARNING and CAUTION decals on instrument panel in plain view of operator and on

body and hoist. See goldenrod sheet B72952-1275 for placement.
