Martin53Cranbrook Posted June 4, 2011 Report Posted June 4, 2011 i just can't get her timed and tuned right, and with the wobble on the crank pulley it's hard to get a reading on where it's at or needs to be with the timing light and i can't really tune using a vacuum gauge cause the only vacuum line i have is the vac advance, i try to tune it by ear but that's not quite working, and today when i was trying to set the timing i moved the distributor too much and snapped off the copper line for the vacuum advance and now i gotta replace that :mad: Quote
Joe Flanagan Posted June 4, 2011 Report Posted June 4, 2011 There should be a port for the windshield wipers on the rear of the intake manifold. You can attach the vacuum gauge there. Can you get the pulley off and reinstall it so it doesn't wobble? It would also be a good time to clean up your timing marks so you can see them. Quote
greg g Posted June 4, 2011 Report Posted June 4, 2011 Is your vibration damper, if you have one delaminating, causing the wobble?? If so it may have also slipped giving you a false timing reading. Pull the plugs, have some one assist you, bump the starter while you hold your thumb closing of umber one hole. Have the assistant bump the starter till you feel pressure build agaist your thumb. Now remove the pipe plug in the head over number 6 cylinder. insert a piece of stiff wire about 8 inches long.it will ride the piston through its stroke. Rotate the engine by hand (that's why you pulled all the plugs) till the wire is at its highest position. This will be TDC for both #6 and #1. the pointer on the timing cover should be pointing to the line that corresponds with O or tdc. Now remove the distributor cap, and rotate the dist so that the rubbing block for opening the points is centered on the corresponding cam highspot. Now you are static timed for TDC for #1 cylinder. If your 0 mark does not alling with the pointer your pully is either misalligned, the key way is partially or fully sheared, or your damper is in the process of coming apart. Quote
Martin53Cranbrook Posted June 5, 2011 Author Report Posted June 5, 2011 well part of the problem is my crank pulley doesn't look like a damper but just a regular pulley with timing marks so that has me a little confused, also i heard from a friend that it's possible that i don't have a damper but the motor is balenced with a weighted flywheel, anyone know for sure?

greg g Posted June 5, 2011 Report Posted June 5, 2011 They built them both ways, no way to tell the whys and whens. Usually the center li is longer than the others So try to to rotate it around to where you can reach it, clean it up with some sandpaper/steel wool, and mark the center line (TDC) with paint of chalk. If you have a timing light, it will work if you hook it up to a 12V battery or jumper pack, then hook the spark plug clip or wire just as you would normally. Quote
Jim Saraceno Posted June 5, 2011 Report Posted June 5, 2011 I'm not sure I understand how you can have a crank pulley wobble. If it were a damper that had delaminated, I can see that. If it is the straight pulley, it would have to be bent out of shape to wobble and therefore should be replaced. Quote

Young Ed Posted June 5, 2011 Report Posted June 5, 2011 Does it look like this? If so and it wobbles it needs to be straightened or replaced. Quote
Martin53Cranbrook Posted June 6, 2011 Author Report Posted June 6, 2011 yeah that's what i got, so i take it i have just a regular crank pulley on there and not a damper? and if that's the case is the motor baleneced with the flywheel? Quote

Yes just a regular crank pulley. No damper. Can't say I've ever heard that the motors were balanced with the flywheels. I'm sure mine just has whatever flywheel was convenient installed. Quote
