INSTALLATION INSTRUCTIONS ` Raise the vehicle on a hoist to a workable height. Remove the front drive shaft (C) at the transfer case flange (D). In order to easily install the LTPTO, the cross member (E) must be lowered from the main chassis (F) by approximately 30mm. Using a 14mm socket loosen the eight bolts (g) supporting the cross member (E) . Use the appropriate safety equipment to support the cross member and prevent it from falling. Remove the rear backing plate (I) from the transfer case (t/case) (H) with a 14mm socket. Use a container to collect any oil that may leak from the t/case after the rear backing plate is removed. Remove all old gasket glue from around the mounting face (M) of the t/case (H) ensuring not to damage the mounting face. Then replace the rear backing plate (I) to prevent possible contamination during future steps. Parts of the t/case (H) must be modified in order to allow the units engagement cable to be mounted correctly. As illustrated in the picture, (looking from front of vehicle), remove the small amount of the material on the rib and lip as shown. The amount can be checked by loosely mounting the LTPTO unit and checking that the cable sheath does not foul on the case. While the rear backing plate is installed use a die grinder to complete this task, remove the backing plate to test the unit. A second rib may have to be modified, in order to determine this; loosely mount the LT PTO unit (1) and check to see if the rib (J) shown will prevent the unit from seating correctly with the transfer case. Then, if required, die grind a small amount of material from the rib (J) to ensure the correct mating of the two faces. A gap of at least 3mm between t/case (H) and LTPTO (I) should be sufficient to ensure a correct seal is created between the two faces. If the backing plate (18) on the LTPTO is installed at this stage remove it by undoing the nine x M5 Socket Head Cap (3) Screws (SHCS) – with a 4mm Allen key.
