Edelbrock Accu-Drive® Camshaft Gear Drives
The Accu-Drive® camshaft gear drive kit replaces a stock timing chain with a precision gear drive system.
The gear drive can be easily installed. Just replace the stock crank and camshaft sprockets with Accu-
Drive® gears and slip in the idler assembly. Most Accu-Drives require no modifications to the engine block,
although some fitting of the axles and front cover may be required.
The Accu-Drive® gear drive system transmits power from the crankshaft gear to a full floating main idler
which drives the camshaft gear. A unique feature of the Edelbrock Accu-Drive® system is the ability of the
main idler gear to float to an optimum position between the crankshaft and camshaft gears, assuring
absolutely equal load sharing between the crankshaft and the camshaft gears. The gears are made from
billet SAE-1144 steel with induction hardened teeth. Gear teeth are shaved for precision operation. The set
features hardened and ground idler pins from billet steel.

Cam and Lifter Assembly Lube
Blend of lubricants ensures proper engine break-in when used according to instructions. Apply to each cam
lobe and to the bottom of each lifter at the time of camshaft installation. Prevents cam lifter scuffing during
the break-in period. Improper lubrication can result in costly camshaft damage. Also applicable to rod and
main bearing installation.
