Adjust A Chevrolet Solid Lift Cam

Adjusting the valve train when using a solid lifter cam involves the twin procedures used as when adjusting for a hydraulic cam. The single valid characteristic is the clearances involved, which are generally a babyish wider than with hydraulic lifters. This article is by necessity quite accepted in terms of clearances and procedures involved; consult your cam/engine manufacturer for the exact clearances and aligning of habituation required for your engine.


Instructions


1. Remit the engine to gallop for 15 minutes to bring it up to temperature, then shut it off.


2. Remove one valve encompass quickly by removing the bolts and lifting it autonomous. This may wish the usage of the 6-inch extent.


3. Using the correct socket and 3-inch time provided decisive, attach the 1/2-inch operate ratchet to the Eccentric person pulley bolt, located in the centre of the crankshaft pulley.


4. Turn the engine over with the 1/2-inch ratchet until the valve following to the front closes completely and the rocker arm is at its resting heighth. It may aid to rock the crankshaft back and forth in cramped increments to effect that the rocker arm is at the centre of its resting cycle.


5. Secure the appropriate-sized wrench encompassing the lock fan in the centre of the rocker arm to conserve it from Stirring.


6. Using the obtain object, turn the valve train habituation screw in the centre of the seed counterclockwise one half of a rotation. This Testament generally be an Allen-head wrench or a flat-head screwdriver.


7. Include the select Tentacle gauge (consult your cam manufacturer) between the rocker arm contact and the valve attitude, and research for clearance.


8. Create trustworthy the feeler gauge fits between the valve belief and rocker arm. Provided it doesn't, there is not Sufficiently clearance. Turn the adjusting screw a half turn counter-clockwise.


9.16. Apply a thin layer of gasket sealant to both surfaces.17.Stick the gasket to the head with sealant and replace the valve cover. Tighten the bolts to the appropriate torque.


Probation to see if the feeler gauge slides too easily without resistance from the top and bottom. If it does, there is too much clearance. Repeat the procedure above, turning the adjusting screw clockwise instead of counter-clockwise to tighten the clearance.


11. Repeat the appropriate tightening or loosening procedure until the gauge just slides between the rocker arm and valve stem.


12. Remove the feeler gauge.


13. Hold the adjustment screw still with the Allen wrench, and turn the locking nut counter clockwise to tighten it and lock in the clearance. You are now finished with this valve.


14. Repeat steps 4 through 13, moving back along the cylinder head to each valve in sequence until all are adjusted.


15. Remove the old valve cover gasket. Clean the mating surfaces of the cylinder head and valve cover with solvent.


Holding the adjusting screw in situate with the Allen wrench, turn the lock kernel clockwise until it stops and locks the clearance in situate. Proof clearance with the Tentacle gauge.10.



18. Restart the engine and allow it to idle for 15 minutes to re-heat.


19. Repeat Steps 2 through 17 on the other side of engine.
