Posted via FF MobileDoc - I give excess detail at times - leave it as Glad it`s out now. 2. Many engines have cam sprockets keyed or locked to the cam in one position - was just asking the "stupid" question to confirm yours are adjustable as ours are - sprockets turn freely when attachment bolt loosened. Grumpy - trying to visualize why movement of sprocket while tightening crank bolt would be a problem. wouldn`t that be tightened B4 locking the cam bolts to finalize timing?

Get my drift? An "interference" engine is one that when the crank and the camshaft(s) get out of time (ie. when the timing belt breaks) a piston can come up and smack an open valve. Still not sure about your engine. The reason for the pulley removal was because the timing belt cannot be weaseled out from "behind" the crankshaft pulley after the belt is slid off the camshaft sprockets? Is the exhaust manifold on the front side of the engine or on the firewall side?
my engine: yamaha/sigma/alloy.

"The reason for the pulley removal was because the timing belt cannot be weaseled out from "behind" the crankshaft pulley after the belt is slid off the camshaft sprockets?" - yes!

Exhaust is firewall side.

Rotate the crank after removal just to make sure it's free and doesn't bind. Then go about install process.



In regard to your question about the cam gears,






So when you go to set the timing you do the tensioner first to take up any slack in the belt then tighten the cam bolts. If you do the cam bolts first then the tensioner there is a better chance of changing cam timing (just slightly, but slightly can have a negative effect). There is also the case of tightening the cam bolts with the cam bad in place that the tensioner will not take up all the slack in the belt, in which case the belt may be loose and timing could jump (very off chance but still a chance).
Just go through the steps to best eliminate any possibility of error.
"So can the timing pin be removed?"

Don't know yet - been raining ''here', so ~ "rain stops play"
