Camshaft Installation Instructions :
1. Thoroughly clean camshaft including oil passages before fitting.
2. Check you have the correct camshaft. Put your new cam against your old cam and make sure all lobes, gears, dowel pins, keyways and cam angle sensors are in the same position. Check the part number on the camshaft matches the part number on the timing card supplied with the cam.
3. Camtech Cams must be installed and “dialled in” by a qualified tradesperson.
4. Follow the vehicle manufacturer’s instructions for removal, re-fitting and torque settings of all parts. Follow Camtech Cams cam specification card for dialling in your camshaft and setting valve lash as this may have changed from the manufacture’s setting.
5. Flat Tappet Cams. New lifters must be installed when using a new or reground camshaft. If new lifers are unavailable for your engine Camtech Cams can radius/machine your lifters to suit your cam. Only use new lifters recommended by Camtech cams or lifters radius/machined by Camtech Cams.
6. Roller Pushrod Engine Cams. We recommend to replace roller lifters when installing a new roller camshaft.
7. Hydraulic Flat Tappet and Hydraulic Roller Lifters. Hydraulic lifters supplied by Camtech Cams DO NOT require pre priming. DO NOT soak the lifters in oil. Install the lifters as supplied. We advise to soak the roller wheel only in oil on all hydraulic roller lifters.
8. Overhead Cams. Check followers and rockers for wear. Replace rockers or followers if there is any scuffing on the mating surfaces. These surfaces must have a fine surface finish (less than 4RA).
9. Coat the camshaft lobes, distributor and oil pump gears with the assembly lube supplied and install your new cam. Do not use engine oil on the cam lobes, use engine oil on the journals only.
If you have flat tappet lifters, direct acting lifters or an OHC engine with slide rockers, coat the surfaces that contact the cam lobe with the lube supplied.
10. Replace timing gears, chain and or timing belt. Use race quality timing sets. Check all distributor and oil pump drive gears that come into contact with the cam for any sign of wear and replace as necessary.
11. You must check inlet valve to exhaust valve clearance, valve to piston clearance, valve to block clearance and all valve train components clearance as this will have changed with the use of a performance camshaft.
12. In some cases the base circle diameter of your cam may have changed. If so, check such things as hydraulic lifter preload, rocker geometry and cam to rocker wipe pattern.
13. Thoroughly check all valve train components and camshafts have adequate clearance and are not fowling against other engine components including cylinder heads and blocks.
14. It is extremely important that the valve springs used have the correct open and close pressures and adequate clearance to coil bind. Recommended minimum valve spring coil bind clearance .060”. Also check valve spring retainer to valve guide clearance, a minimum of .060” is recommended. In non-roller cam engines where heavy dual springs are used it is recommended to run the cam in using the outer springs only.
15. Install the camshaft using the standard timing marks and “dial in” your cam as outlined below.
16. Find TDC on number 1 cylinder and mark this position with a pointer on your degree wheel.
