Pictures on Removing 4-tec camshaft in 20 Minutes
Few people have asked me small particulars about removing the cam in our skis and what al is involved. If you dont have a shop manual, here's a quick visual rundown. It's very simple, and no special tools are needed. I just removed the cam out of my head and took pictures along the way and it took me 23 minutes including stopping for pics. Very simple.
1. Remove plastic engine coowlings, remove spark plug coil packs,and remove 8 bolts holding valve cover on the head (E8 or 1/4") ...
2. Remove valve cover and push it to the side since the vent hose is still attached to it. Also remove the 3 spark plug boot tunnel things ... they just pull out with some strength
3. Remove two E8 1/4" torx bolts to remove access cover to cam gear. Also remove THREE 5mm? allen/hex bolts that hold the cam gear on. Also remove the camchain tensioner behind the throttle body/behind oil filter with a 8mm? hex/allen
take the camchain off the gear, set gear aside, and either drop camchain down into motor, or PREFERABLY wire tie the camchain to something atop the motor for easier retreival for reassembly.
*** the camchain falls, no big deal... get a magnetic wand and it'll come right back up
4. Remove SIX E10 Torx bolts that hold the rocker shaft to the cylinder head. After 6 bolts are removed, entire rock shaft, arms, assembly will come off the head... safely set aside
5. Pull out camshaft retaining clip
6. Slide camshaft out thru the opening where the cam gear was
7. Cam is now removed.... hopefully you did all this work because you are installing a better camshaft
****NOTE: ... Shop Manual Suggest NOT to re-use rocker arm stretch bolts.

My favorite part is where the cam bolt head strips out because the access hole is just small enough to put my allen driver in at an angle.
Now I'm fooked.

Steve, how do you handling the timing setting when putting back together? It there a reference mark on the cam or chain or what?

what about the bolts? Do you have to buy the ARP bolts? (at $191.00) or can you just get new regular bolts?

The ARP head studs are a good investment IMO unless you feel you'll never have the head off again. The head bolts are about $90 a set give or take. Buy a set of head bolts twice and you're at the cost of the head studs that you can re-use over and over..

Does anybody have a picture of the Cam Sensor? I can't figure it out, I might have lost it? Dunno confused..
