5 2.2 INSTALLATION OF THE CHASSIS BRACKETS Remove any bolts such as battery box and/or exhaust hanger mounts that will interfere with the chassis bracket mounting Mark the reference hole T1 from the top of the frame down to the reference hole. Mark the reference hole CC1 from the center of the transmission u-joint or X1 from the body mount hole. Drill a single 7/16 hole in the frame and bolt the chassis bracket (TIB07000) against the outside of the frame using the reference hole in the center of the bracket and 4.25 down from the top of the bracket. Rotate the bracket to the angle specified on the installation drawing. NOTE: Use electronic anglemeter with 0.1 accuracy (e.g. SPI Pro360 digital protractor). All angles indicated are with frame reference of 0. Drill four additional 7/16 holes in each frame rail using the chassis bracket as a template and secure chassis bracket to frame with the flanged head bolts 7/16-14UNC x 1.75" (TIF07002) and flanged lock nuts (TIF07003) included in the kit. Tighten the 7/16 bolts to 70 lb-ft (±10%). Drill through the chassis bracket any holes needed for battery box and/or exhaust hanger mounts and reinstall the original bolts that were previously removed. It may be necessary to make a 5/16 spacer to keep the accessory brackets flush on the outside of the frame rail. Brackets are slotted so that they can be installed in the stretch area.

6 2.3 ASSEMBLE THE TELMA BRACKETS AND MOUNTS Identify the driver s side of the Telma from the passenger side. The power connection block is on the passenger side top corner and the ground is on the driver side top corner. Identify the Telma brackets. The longer bracket TIB07005 is for the driver s side. The shorter passenger side bracket is TIB Use medium strength thread locking adhesive (e.g. Loctite 243) on all fasteners and mark with paint after tightening to proper torque. Use three hex head bolts M12x1.75x35mm (TIF07001) and Trep washers (VF201400) provided in the kit to attach each Telma bracket onto the unit. Tighten bolts to 30 lb.-ft (±10%) CAUTION: DO NOT OVERTIGHTEN! Install the rubber mounts into the retarder brackets as shown below. Insert the male parts of the rubber mounts into the 1 5/8 holes in the brackets from the bottom and the other half of the rubber mount on top. Place one 2 ¾ diameter 5/8 flat washer on the top and bottom of each mount and another on the bottom between the chassis bracket and nut. 2.4 INSTALL THE TELMA IN THE CHASSIS Lower the Telma, equipped with its brackets and mounts, into place on top of the chassis brackets. Install the M16x1.5x100mm (4 ) bolts and spring washers down through the holes in the mounts and brackets at each mount. Install 2 ¾ diameter flat washers, spring washers and M16 locknuts at each mount as shown below and tighten to 150 lb.-ft (±10%). Page 6 of 23 6nov15jh

7 2.5 DRIVE SHAFT MODIFICATION AND INSTALLATION A slip assembly is required on each side of the Telma. The slip position should be at center of slip travel when the shaft is installed. Refer to GM Upfitters guidelines for proper drive shaft manufacture, balance, straightness, and critical speed limits. Refer to the appendix for Telma guidelines. Refer to the installation drawings in the appendix for shaft length guidelines. Shaft lengths over 50 should use 4 tubing. Always verify proper shaft lengths before modification. Connect the Telma flange yoke of each drive shaft to the Telma coupling flange using the M12x1.75x25mm 12 point head bolts (TIF07000) supplied in the kit. Tighten to 80 lb-ft (±10%). Use medium strength thread locking adhesive (e.g. Loctite 243) and mark with paint after tightening to proper torque. Page 7 of 23 6nov15jh

8 2.6 AXLE SHIM INSTALLATION Some installation configurations require the addition of steels shims to adjust the axle angle. Refer to GM guidelines for proper shim type and procedure Below are some guidelines - Loosen the spring u-bolt nuts - Lift the chassis by the frame rail until the shim can be slid over the centering pin. - To reduce the axle angle (as shown in the example), the thicker part of the shim should be toward the front of the vehicle. The nose of the axle will go down. - Lower the chassis and tighten the u-bolts. In some cases a new spring pack bolt will need to be installed to make sure the centering pin extends far enough into the spring pad hole. 2.7 EXHAUST MODIFICATION Modify the exhaust as shown below to clear brackets.
