ok .. I don't know if some of you remember about my buddy's '93 1/2 ton p/u problem.. anyhow it was backfiring and doing weird stuff... everytime he went to a different garage they would charge him $60 and tell him they set the timing.. we checked the reluctor on the dist this weekend .. sure enough if you hold the rotor you can move the reluctor about a 1/4 turn both ways..

anyone know how to fix this?? I was told you have to replace the dist. base?

 

Jeff,

I'm not sure I'm even talking to you right now, after that "game" on Sunday...

Actually, your guys earned that gold medal. It was a very good series, and a good game, for about two periods. Everyone skated hard, then your guys really lit it up. It was a great game to watch either way, and about time the Canucks wiped out that long drought.

Congratulations to all the Canucks from your brothers in the "south".

And screw the Russians (whining babies). Hockey is a Canadian sport, not a Russian one. If they want to be allowed to play, they'd better learn to lose gracefully once in a while. O.K. - more than once in a while

And as for that distributor problem, the reluctor may be a problem, or maybe not. You are probably going to have to remove it either way. I'd strongly suggest rotating the engine to a fixed point (like TDC on the #1 cylinder), disabling the ignition so the engine doesn't inadvertently get bumped, then marking the rotor position and removing the distributor.

Once the distributor is out you can get a closer look. There may be some wear in the rotor plate or advance mechanism, or the movement may be the normal advance allowance. It's really difficult to see in the engine. It would also be a good time to inspect the bushings, gear, and clean everything thoroughly. You could even relube the wick that oils the upper bearing if the distributor isn't completely worn out. Repair any loose parts or get a replacement distributor once you determine the problem, and you may have your whole problem solved.

Then get back on the ice and practice - world championships are only a year away, and we'll be looking for you...

 

I'm not up on my electronics terminology but I think I know what you mean. I think you're talking about the little wheel with 8 "teeth" on it that is attached to the distributor shaft. If it's this wheel that's rotating around the shaft, the shaft is shot. I think I played around with one a few years ago and it's a press-fit around the shaft. Once it works loose it'll never be right again. There is no centrifugal advance mechanism in a 93 truck engine so this toothed wheel should have NO play in it. It should be locked tightly to the distributor shaft.

However, if you are talking about the magnetic pickup that that goes around the wheel and sends the signal to the module then I beleive that's just screwed to the floor of the distributor. Again, there is no advance mechanism in your distribotor so this part doesn't move like in an earlier non-computer controlled distributor with a vacuum advance mechanism. That's why it can be attached firmly to the floor of the distributor.
