"Hi-torque" starters can mean a starter made with a gear reduction to add mechanical advantage, or it can mean a starter wound with an armature that delivers more torque than a "standard" starter. | "Hi-torque" starters can mean a starter made with a gear reduction to add mechanical advantage, or it can mean a starter wound with an armature that delivers more torque than a "standard" starter. | ||

High torque starters are generally used on high performance engines. They are better at cranking over a high compression engine. They are usually less prone to heat soak. Most also have universal mounting so they can be used with different flywheel sizes, and they may have a feature that allows the solenoid to be "clocked" into a position that gives the best clearance. | High torque starters are generally used on high performance engines.

| − | + | Most aftermarket high torque starters are originally Japanese manufactured. While China has copied these and supplies a number of starter "sellers" with their own name branded units, in general the starters all feature the same basic construction. | |

| + | Most of the failures related to these starters involves damage to the pinion gear. Replacement pinion gears can be obtained and the starter disassembled, the gear replaced, the starter reassembled and placed back in service. Most starters will have the 9 tooth pinion gear although a few will have 14 tooth pinions. | ||

| + | *With the starter on the bench, first use a paint marker to provide alignment marks on the main motor housing and the gear housing. | ||
| + | *Remove the three bolts holding the starter to the aluminum mounting block. For ease of re-installation, marking the clocking of the starter motor is suggested. | ||
| + | e reverse order of the disassembly. | ||
| + | *Pay close attention to the orientation of the solenoid actuator as it must go back in the proper way. | ||
