Ok, these are a little tricky. also if the timing is not set correctly, engine damage will occur. the valve's will hit the pistons if mistimed. follow these instructions carefully.
the problem here is, the balancer does not have a timing mark. the cams and chain are supposed to be paint marked before removal. you may need to start from scratch. give me a few mintues while I upload the info!!
Install the crankshaft sprocket with timing mark at the 5 o'clock position.
Lower the timing chain through the opening in the top of the cylinder head. Carefully ensure that the chain goes around both sides of the cylinder block bosses (1, 2).
Important: Always install NEW sprocket bolts.
Install the exhaust camshaft sprocket with the timing chain matching colored link (3) at EXH triangle aligned at the 10 o'clock position.
Install the timing chain upper guide.
Tighten Tighten the timing chain upper guide bolts to 10 N·m (89 lb in).
A new tensioner should be supplied in the fully compressed non-active state. A tensioner in the compressed state will measure 72 mm (2.83 in) (a) from end to end. A tensioner in the active state will measure 85 mm (3.35 in) (a) from end to end.
If the timing chain tensioner is not in the compressed state, perform the following steps:
the ony way to know if the crank gear is at 5 oclock position is with the front cover off. normally the correct procedure is to make sure it is in the correct postions before you remove any timing components. in other words, at tdc before tearing apart. or the method I use is line everything up before taking apart, then paint mark everything. unfortually you are in a postion now you will probably have to remove the front cover to set up correctly. do you need the front cover removal instructions.
you are quite welcome. Glad to help.
