8100 Series Ultimate Adjustable Timing Sets
Thank you for choosing COMP Cams® products; we are proud to be your manufacturer of choice.
Please read this instruction sheet carefully before beginning installation, and also take a moment to
review the included limited warranty information.
Installation Instructions:
The COMP Cams® 8100 series adjustable timing set makes infinite cam adjustment quick and easy.
Simply install your 8100 series adjustable timing set with the adjustable cam sprocket aligned and
tightened (13-14 ft./lbs.) to “0” for a straight up cam position or advance/retard your cam by adjusting
the cam sprocket accordingly.
Ford Windsor Instructions:
To use the thrust bearing in the #8138 kit, you will need to counter sink the holes in the thrust plate and
use counter sink bolts (not included), that will tighten flush or below the thrust plate surface. Affix the
bearing to the engine side of the sprocket with the black mark facing the engine. Note: Failure to
perform this modification to the thrust plate will destroy the bearing during installation due to
the thrust plate bolt to thrust bearing contact.
Thrust Bearing & Washer Installation:
Thrust Bearing Instructions
1. Properly lubricate the thrust bearing assembly using engine oil.
2. For Ford engines: Install the bearing with the “black” mark facing the engine
.
