AR177 Crank Trigger mounting kit with TDC pointer for Jesel Belt drives

This crank trigger bracket assembly solves several issues for engine builders who are using the Jesel belt drive system on a Mopar big block or Hemi motor. This bracket assembly provides a mounting location for either a ¾-16 thread crank trigger pickup or a 3/8 diameter pickup as well as an adjustable TDC pointer. This kit is designed to work with the MSD trigger wheel mounted on an ATI #917127E damper. (The #917127E damper with its longer hub is required to clear the belt drive assembly)

The bracket assembly also has a built in mounting point in the lower left hand corner that is suitable to use as a pivot point for an accessory such as an alternator or vacuum pump. The crank trigger bracket has dimple marks located every 2 degrees of crank rotation for quick timing adjustments.

The bracket assembly comes complete as shown with the bracket assembly, TDC pointer, and two crank trigger brackets. Shown in the picture above is a 3/8 diameter pickup MSD PN8153. This pickup has 3/8-24 thread and an armored cable. Other styles are available; see the MSD catalog for more information. A MSD pickup is not included in this kit and must be purchased separately.

There are several optional parts for the AR177 kit which allow this kit to be used for other applications. AR Engineering part number AR259 is a billet aluminum bracket designed for the 3/8-24 MSD pickup when using an 8 inch BB Chevy trigger wheel. Part number AR260 is also for the BB Chevy trigger wheel but it is designed for the larger ¾-16 MSD pickup. AR Engineering part number AR179 is a billet aluminum bracket designed for the ¾-16 trigger pickup when using the Mopar crank trigger wheel shown above. Also available is AR299 which is a billet aluminum bracket with 3/8-24 thread for use with the Mopar crank trigger wheel.
