[QUOTE="Chiefblueman, post: 1132587, member: 29249"] Just finished my first valve check and adjust a few weeks ago. I see you have a Gen1. If you haven't changed the CCT, now's a good time. Get a timing chain cover gasket just in case you need it. I found the most difficult part of the job to be getting to and the actual removal of the cam cover. Disconnecting throttle cables from the bar will help here. If you don't change CCT and don't need to adjust, the checking is easy. Tips for CCT replacement and cam removal if needed. Remove timing chain cover slowly and try to keep the pin on left side that locates cct in the case. When cover is off, do the tyrap thing. I also tyrap the cam gears to the timing chain. I removed the timing rotor from the end of the crank, exposing fully the crank gear/ timing chain. I cut a piece of closed cell foam, often used in packaging, and wedged it under the crank gear. This applies pressure to the timing chain 180* around the gear. It's not going anywhere. Also marked tooth and chain. I cleaned the cam gears and chain and marked the gear and chain with a sharpie to align tooth to link. Had to adjust my intakes requiring cam removal. Service manual has you take the cam out, but with CCT removed there is enough slack in the chain to roll the cam out of the way maintaining mesh with chain. Great tip I got here. I used a micrometer and sanded the intake shims on glass to bring clearances from low spec to mid spec. Take your time, be methodical. If your AIS is still in place, now's a great time for some WynnPro plates! I searched the heck out of this site before doing this. Way better info here than the FSM. This place rocks[IMG]https://www.fjrforum.com/forum//public/style_emoticons/default/punk.gif[/IMG] Have fun with your tech session. You can do it! [/QUOTE]
