Hi folks, have not been here in awhile, don't remember my old name!!! I've gone from an 86 to a '98 Ranger 4.0, and it recently developed the "bird chirp." It's the dreaded cam syncronizer device, which is on order at NAPA. So I have some questions:
Anybody know the TRUE cause of this failure? Distributors never used to wear out in less than 80K, why should this thing?
Examining the old one, what appears to be an oil hole below the O ring looks pretty dry. Could this be an oiling problem?
INSTALL: I won't know 'till tomorrow if the NAPA one comes with the alignment tool or not, how critical is this? I did the following:
Set the engine on no1 to fire, 10 BTC, and carefully "sighted" the rotational position of the syncro. Then, with the sensor off, I can see the vane edge aligns with one side of a slot in the housing, so I can get it close.
BUT if the new one comes with a tool, the manuals I have are ambiguous. The factory manual has an incorrect drawing of the timing marks, and does not state just where to put the engine.
An aftermarket manual I have says 10 ATC even though there IS NO such mark. ONLY TWO MARKS on the wheel are TDC and 10 BTC.
So the questions are:
Just where do you set the engine position?
If I get no tool, is my alignment close enough?
Just how close does this have to be?
What is the root cause of these failures?
