09. After we removed the sprockets and primary cam we noticed the primary cam tensioner had seen better days. The plastic shoe material demonstrated unusual and serious cracking. It's a good thing we noticed this before engine damage occurred. We checked the oil pump for any signs of wear and it looked good as new. The secondary tensioner looked like new with no damage.09. After we removed the sprockets and primary cam we noticed the primary cam tensioner h 10. The old cams simply slid out from the camplate and the new cams slid in. No tools or press are required for assembly in the newer style ('07 and later) camplate. Todd used a straight edge to ensure the timing marks on the new cams lined up.10. The old cams simply slid out from the camplate and the new cams slid in. No tools or 11. Before reassembling the cam chest contents we cleaned the oil pump and generously lubricated it with assembly lube.11.

This step is important to make sure there is proper lubrication on initial startup.12. The new cams also received a healthy application of assembly lube. This step is impor 13. Once the camplate was reinstalled the larger camdrive sprocket and the cam drive sprocket on the crankshaft were installed (along with the primary cam chain) with the timing marks aligned. A new primary chain tensioner was also installed followed by the cam cover gasket and cam cover.13. Once the camplate was reinstalled the larger camdrive sprocket and the cam drive spro 14. While new cylinders, pistons and rings come in the kit, Todd wanted to measure the piston ring end-gaps before proceeding. Each ring was inserted into the cylinder and pushed down approximately 1-inch with the piston to make sure the ring was square and level in the cylinder.14. While new cylinders, pistons and rings come in the kit, Todd wanted to measure the pi 15. Then with a feeler gauge Todd measured the ring gap distance for all of the rings. While many builders omit these measurements, it's a good idea to make sure the rings fit correctly to avoid future oiling or compression problems.15. Then with a feeler gauge Todd measured the ring gap distance for all of the rings. Wh 16. After the rings were fitted to the new piston Todd attached the pistons to the rods using new piston circlips and pins. A ring compressor was used to compress the rings to allow the cylinders to be easily slid over the pistons.16.

New head gaskets were placed atop the cylinders before each head was reinstalled and torqued down to factory specs.18. New head gaskets were placed atop the cylinders before each head was reinstalled and 19. Each of the rocker assemblies was cleaned up before putting a new gasket on top of the head, dropping the pushrods into place, and reinstalling the rocker assemblies.19.
