Note to HPI Savage Owners: Installation of the TigerDrive units into the Savage chassis requires extensive modification of suspension components unless the Extended Chassis Kit has been installed! Some documentation of these modifications has been published in major forums and personal websites. Due to the nature of these sites, we do not provide links to them. However, most can be found through a basic web search.

Notes:

1). The start shaft of this engine is shorter than most and requires a slight modification of the TigerDrive unit to ensure maximum life from the one-way bearing. To ensure that the one-way bearing engages the shaft as fully as possible it must be pressed further into the large bevel gear. To do this place the TigerDrive Bracket on a hard flat surface with the gear resting in its normal position. Be sure that the brass washer is in place and laying flat under the gear. With the gear resting on the bracket, drive the one-way bearing downwards until it contacts the surface that the bracket is resting on. To do this use a soft faced hammer or small wood block to cushion the bearing edge from being deformed. Once the bearing is repositioned simply install the TigerDrive as normal.

2). Engines noted as "Require Shim - .XXX" will have interference problems if the TigerDrive is mounted as provided. The Shim is to be placed between the backplate of the engine and the mounting bracket of the TigerDrive preferably at the bolt locations. Any material can be used to build to the thickness specified in the note. The dimension shown is in inches and should be the minimum thickness used. A thicker shim or combination of shims can be used however care should be taken that the total thickness is not more than .020 greater than the recommended thickness. The flat #4 washers provided in the hardware pack can be used in some cases as they are approximately .025 inches thick. Sullivan also offers a shim kit which will simplify this effort, Shim Kit p/n S698. These include 4 custom .020" thick shims and are available anywhere TigerDrives are sold.

3). This engine has a recessed backplate that requires the S702 TigerDrive to be modified for proper gear mesh. To correct the gear alignment place the bearing-gear assembly on a hard flat surface with the printed side of the bearing facing up. Place a socket or tube whose inner diameter is larger than the bearing but Outer Diameter is smaller than the gear over the bearing so that it rests on the gear. Next gently tap or press the gear down until it is flush with the bottom of the bearing. If possible apply some retaining compound on the surface of the bearing where the gear will come to rest before repositioning it. A wicking grade compound can also be applied after the gear is moved. Once this is done install the gear-bearing assembly as normal making sure that the printed side of the bearing faces towards the engine.
