This unit is made of aircraft quality steel right here in the United States, all in Milodon’s own plant. With proper installation, this gear drive will out last and out perform any other cam timing device available. Follow these instructions carefully. We recommend that the engine be on an engine stand to install the gear drive. If this gear drive is to be installed on a fully assembled engine, rather than just initially being assembled, rotate the engine to T.D.C. #1 cylinder compression stroke. Remove the stock cover, gears, timing chain. Prepare the front of the block with a stone or file, and debur the area around the front of the cam boss.

Step 1
Clean and inspect all parts.
Step 2
Back the set screw in the polylock all the way to the top of the hex end. This will provide the proper room to set the lash on the valve.
NOTE: All rocker arm adjusters must be checked for proper clearance between the “base” of the rocker arm adjuster (also referred to as polylocks) and the inside of the upper rocker arm pivot slot. Clearance between the “base” or lower portion of the rocker arm adjuster and the inside radius of the upper rocker arm pivot slot is critical to the proper operation of the valve train. Rockers must maintain full range of motion without any binding or interference between the rocker body and rocker arm adjusters. While many rocker arm designs accommodate the larger polylock “base” diameter, some rocker bodies incorporate narrower pivot “slots” in their design. Please contact PRW directly if you find that your rocker arms require the smaller diameter polylock “base” and these rocker arm “adjusters” will be exchanged at no charge. ADDITIONAL CLARIFICATION: Before installing this aluminum stud girdle, please check to confirm that the “base” of the stud girdle rocker arm “adjusters” (polylocks included with this product) fit inside the upper rocker arm pivot “slot” and move “freely” in your rocker arm. If there is little or no clearance, you may need to contact PRW to exchange these “adjusters” for the latest design. Please contact PRW Customer Service directly at 888-377-9779 or email info@PRWnetwork.com.
