Howdy,
I want to check my timing chain because i have no idea if/when the POs changed it. Came across this website where duder writes about easy way to check timing chain slack:
http://www.misterfixit.com/chanslop.htm
Here is what i'm confused about (assuming this method is legit)..
He says:
"Pull the distributor cap and observe the rotor position. Take a breaker bar and a appropriate socket and put it on the crankshaft damper pulley."
Where is the bolt on the on the crankshaft damper pulley he is referring to? Is it necessary to remove the fan to get to it?
He goes on:
"... Slowly turn the crankshaft pulley in a clockwise direction. Watch the distributor and observe that the rotor is moving. Stop turning. Now - mark the damper pulley position with the chalk or observe the degree wheel. Very carefully turn the crankshaft in the other direction and VERY carefully observe the rotor in the distributor. The instant it begins to move STOP turning and mark the crankshaft position again. Measure the number of degrees of rotation of the crankshaft."
I was able to turn the pully with my hands (with some difficulty), and i turned it pretty far, but i did not observe any movement of the rotor. Does this mean anything?
Besides this method, are there other nifty ways to check the condition of the timing chain without having to take everything apart?
Or is this something that i should just assume needs changed and go ahead with buying the part and changing it?
Thanks!
