Auxiliery pulley

[geno58]

just put a new timing belt on my 2000, every thing lined up, but after turning the motor over a couple of times, I noticed that the auxiliery pulley (oil pump drive) appears to be a tooth or two off. Is this a problem?

Not sure what you mean by " a tooth or two off" ?

In the manual, it says that the hole in the pulley should be in allinement with the pulley bolt and the tensioner bolt, when timing marks are in allinement. The hole is about 3/8" to the right of the imaginary straight between the bolts.

when i had my motor apart, i checked out the interference zone on the aux drive. basically there is a lot of fudge room. when the dot is at 12 o'clock and 3 o'clock you are pushing your luck. I set mine in the middle (1:30). if you jumped a couple of teeth, just rotate the motor to TDC and see if you are in the 12:30 to 2:30 range.

The oil pump (probably all that is driven by that pulley) doesn't care about engine orientation and timing marks.

Back when the aux shaft was used to drive a block-mounted mechanical fuel pump, it was much more of an issue. The fuel pump's drive lobe could make contact with the crankshaft if the orientation was too far off. But even that wouldn't really come into play until you were more than a 100 degrees out of position. Having said all that, I'm not sure the aux shaft in your car even has a fuel pump drive lobe and I'm betting you have a cam-driven distributor so there really isn't anything to worry about - just keep it in the ballpark.

Thats kind of what I figured, but I needed to throw it out there. Thank you for your response.

all of the aux shafts I've seen have a lobe, so it's best to keep it as close to possible to the right spot. But there is leeway on the timing marks

both my 79 carb 2000 and 80 FI car both still had the lobe on the aux shaft. doesnt do anything anymore except threaten the crank with annihilation
