When to remove cap from Summit HEI distributor?
Once you feel compression building, look for the zero mark on the harmonic balancer to approach the timing tag. We prefer to set the initial timing for most engines at 10 degrees Before Top Dead Center (BTDC). With that set, remove the cap from the distributor. We’re using a Summit HEI distributor.
What should the rotor be on a MSD distributor?
The rotor should be fairly close to the mark on the distributor. If the rotor is pointed away from both marks, then you will probably have to buy an adjustable rotor from MSD (PN 8421) to correct the problem. This is an adjustable rotor fitted to an MSD distributor.
Which is the top dead center of the engine?
Top dead center, sometimes referred to as TDC, is the point in which the piston in the number one cylinder position of your engine is at its highest point on the compression stroke.
How to find top dead center and set your distributor and?
This procedure is for the 4.3L 1996 and newer engines only. 1991 only has one timing mark on the damper. No need to remove the #1 plug on either engine, (The piston will push air out of the spark plug hole on both strokes when approaching TDC). When the TDC timing mark on the damper lines up with the index on the timing cover, #1 piston is at TDC.
Can you replace the distributor cap and rotor?
To replace the distributor itself, yes, but not just the cap and rotor. Triedaq July 6, 2016, 2:41am #3 The distributor cap and rotor can only fit one way onto the distributor. If the distributor remained in the engine, there is no problem.
