But if you dont have the special tools to get the pins out. Put a metal plate with a hole in it over the pin and put the part of the pin sticking out in a vice and put a chizzle between the metal plate and the vice and wedge it out. Thats how i did it and it worked on every one i pulled out.

Yep no prob. Those pins can be a pain but try my mothod before you go out and buy the tool. Its expensive. No need to waste money that you could be spending on making it go fast! LOL



P.S. I just did a full rebuild myself cuz my oil pump went bad and it killed my rod bearings so if you run into any more trouble feel free to PM me and ill help you the best i can. I had mine down to spliting the cases and replacing the crank but dont ask me about the gears that way to complicated i left them in and i suggest you do the same.

Well got the old rocker arms kinda puzzled by something my rocker arm shafts are different sizes 1's a little shorter than the other :unsure:
compare the new ones side by side to the old ones..if they are the same, then the new ones aren't going all the way in..either that..or you just got the wrong ones ??.

Take the bolt out of the end of the tensioner. Take a tiny flat screwdriver and stick back in the hole and turn it clockwise. This will retract the arm on the tensioner. Hold it in this position until you get the tensioner bolted on. Once you get it bolted on, release the screwdriver and the arm will automatically extend and tension the timing chain. If you don't keep the arm retracted until it's bolted on, it will put too much tension on the timing chain.

BTW, don't forget to put your gasket on the tensioner. After you get the tensioner in, don't forget to recheck your timing marks to make sure it's still in time.

When you lined the T mark up, did you put the lobes on the cam facing down?

No, the lines should be parallel with the head, but the cam lobes should be facing down. When you unbolt the cam gear from the cam, you can bolt the cam gear back on either way, with the lobes up or down. Make sure the cam lobes are facing down, then bolt the cam gear on with the lines parallel with the head and the timing mark on the cam gear at the top.
