Removal of Crank Position Sensor Hole Cover Plate and Plug
The engine is shipped with a crank position sensor hole plug to prevent leakage of fluids during shipping. This plug must be removed to allow
installation of the stock crank sensor.
1- Remove two Torx® #8-32 x 3/8” screws used to fasten cover plate. These screws can be used later to install the crank position sensor.
2- Insert a ¼-20 bolt into the crank position sensor plug.
3- Use a pair of pliers to grip the ¼-20 bolt and carefully extract the crank position sensor plug from the hole. Pull the plug strait out of the hole
to avoid damaging the crank position sensor hole.
Installation of Stock Crank Position Sensor
IMPORTANT! The crank position sensor mounting block used in stock applications is not used with the S&S engine. If this block is installed, the crank
position sensor will be too far from the flywheel. This could cause the fuel injection system to operate improperly or not at all.
1- Slide the stock O-ring (H-D®# 11170) around the crank position sensor up to the metal mounting bracket. Apply a small bead of high-
temperature gasket material around the outer edge of the O-Ring to ensure a leak-proof seal.
2- Insert crank position sensor into crank position sensor hole.
3- Apply a small amount of Loctite® 222 to threads of Torx® #8-32 x 3/8” screws and use them to fasten the crank position sensor to the crankcase.
Tighten screws to 17- 21 in-lb.
