How to install a camshaft using the lift at TDC method
This information is borrowed from the Camshaft Innovations website and all credit goes to Jay Allen for providing this wonderful information. He is a WONDERFUL person to deal with and truly knows his stuff. I would buy again from him in a heartbeat!
Installing a camshaft ground by Camshaft Innovations using the “Lift at TDC” method. You will NOT need a degree wheel. A piston stop and a dial indicator is all that you will need.
1. Install the camshaft. Start by aligning the dots.
2. Make sure the crank gear is set to zero.
3. Use your timing chain cover. Just 2 or 3 bolts to hold it in place.
4. Slide your harmonic balancer on.
5. Install your timing pointer. If it is a stock pointer, grind the lower bevel flat.
6. Now you’ll need your piston stop.
7. Using your piston stop, identify where TDC is with YOUR pointer and YOUR balancer.
8. Adjust the pointer accordingly.
9. Remove the piston stop at this time.
10. Install 1 intake lifter and 1 exhaust lifter.
11. Get the dial indicator out and set it up on #1 INTAKE lifter.
12. Turn the engine over in direction of rotation.
13. When the EXHAUST lifter just starts to come up, STOP!
14. Zero the dial indicator out at this time. You are now on the heel or basecircle of the intake lobe.
15. Turn the engine in direction of rotation.
16. When you get to TDC, STOP!
17. You are at TDC when YOUR pointer is directly on the TDC mark on YOUR balancer. (Providing you set TDC
properly!)
18. Record the lift that is on the dial indicator.
19. How close is it to the “Lift at TDC” supplied by Camshaft Innovations on your cam card?
20. If you need MORE lift, then ADVANCE the camshaft.
21. If you need LESS lift, then RETARD the camshaft.
22. For every 1* at TDC you are off, that is .0075” (+/-).
23. Remove the balancer and the timing chain cover.
24. Advance or retard the camshaft accordingly.
25. Repeat the above steps as needed.
GOOD LUCK and consult Cam Master Jay with any questions you may have!
