Instruction Manual for DODGE Para-Flex GT, GTL, and GFB

WARNING

To ensure that the drive is not unexpectedly started, turn off, lock out, and tag power source before proceeding. Failure to observe these precautions could result in bodily injury.

Install in the following sequence:

(1) Inspect the shaft to ensure that it is smooth, straight and within commercial shaft tolerances as found in Table 1. Inspect the coupling hub to

ensure that the adapter and hub have not been damaged during shipping or storage.

(2) Remove any anti-rust lubricants or oil from the shaft. If necessary, clean shaft end

and shaft seat beneath coupling lightly with emery paper.

(3) Check the axial float of the shafts. Position the shafts at the mid-point of the float.

Where limited end float is required or sleeve bearings are used, consult DODGE for application assistance at 864-284-5700.

(4) Referring to Figure 1 and Table 2, observe the “B” dimension for the coupling size

being installed. Mount and position the flanges on the shafts so that dimension “B” is achieved when the shafts are in their final position.

(5) For Straight bore hubs mount the hub assembly per “Section 1 – Straight Bore Hub Installation” found below. For Taper-Lock bushings/hubs

mount the hub assembly per “Section 2 – Taper-Lock Hub Installation” found below. For Grip-Tight hubs/adaptors, mount the assembly per “Section 3 – Grip-Tight Hub Installation” found below.

(6) Align flanges using precision equipment such as dial indicators or laser equipment. If precision equipment is not

available, scales, straight edges, and calipers can be used as less accurate means of alignment. To achieve maximum coupling performance, align the coupling as accurately as possible during installation.

(1) Insert bushing into hub. Match the hole pattern, not threaded holes (each complete hole will be threaded on one side only). (2) Lightly oil setscrews and thread into those half-threaded holes with the threads in the hub. Do not lubricate the bushing taper, bushing bore, hub

taper or shaft. Doing so could be harmful to the product. (3) Position assembly onto shaft allowing for mild axial movement of hub that will occur during tightening procedure. (4) Alternately torque setscrews to recommended torque setting as shown in Table 4 below. Be careful to avoid using worn hex key wrenches as they

tend to result in a loose assembly or may damage the setscrews.

(5) To increase gripping force, hammer face of bushing using a brass drift or sleeve. Do not hit bushing directly with hammer. (6) Re-torque screws after hammering.

Section 2a – Dismounting Taperlock Bushing Assembly

(1) Remove all setscrews. (2) Insert one setscrew into any half-threaded hole that is threaded on the bushing. (3) Loosen bushing by tightening the setscrew.
