Hemibear426 Posted April 4, 2019 Report Share Posted April 4, 2019 Are the sprocket dot marks supposed to be adjacent to each other when #1cylinder is in compression at top dead center, mine don't seem to be? Thanks for any guidance. Quote Link to comment Share on other sites More sharing options...
ja20 Posted April 4, 2019 Report Share Posted April 4, 2019 (edited) It could be because your on the exhaust stroke. Crank makes two revolutions for one revolution of the cam shaft. Edited April 4, 2019 by ja20 Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted April 4, 2019 Report Share Posted April 4, 2019 the crank turns twice to the cam turning once...regardless of stroke, mechanically it is aligned...it is only with the TDC on compression WILL YOU NEED to time your distributor to that of the valve position...your valves will reveal the stroke....

Hemibear426 Posted April 4, 2019 Author Report Share Posted April 4, 2019 Gotch'a and understood and thank you so much. It appears that when my engine is on a compression stroke at top dead center, that my cam and crank sprocket dot marks are not together. I assumed, mistakenly I believe, that when both the cam and crank shaft marks were next to each other that this was on a compression stroke TDC. Thanks again.

Plymouthy Adams Posted April 4, 2019 Report Share Posted April 4, 2019 I could have done better at answering your question but often my thinking also includes many of the previous threads where folks confuse the damper and pointer and be off 180 with timing (electrically) but yes, when your gears dots are at closest proximity to one another and the dots are aligned though that imaginary line drawn between the center of the cam and crank...your engine is MECHANICALLY synced....I also recommend at this time you should ensure that the oil pump gear is aligned to the cam if you wish to have it set up as per the book for future reference. Then drop you distributor into position with #1 wire in the approx. 7:00 position...this will ensure any future repair can be made by the book and also for ease of tune-ups as it is easy to pull the distributor and replace points on the work bench.

Hemibear426 Posted April 4, 2019 Author Report Share Posted April 4, 2019 I just came in from the shop after getting the oil pump aligned such that I could get the rotor at the 7 o'clock position. Took me several tries to get the tooth alignment correct. This of course was done with the #1 piston at TDC on a compression stroke. I packed the oil pump with Mopar motor assembly grease. Is this okay? Quote Link to comment Share on other sites More sharing options...
ptwothree Posted April 4, 2019 Report Share Posted April 4, 2019 That's how I did mine. Also, for the initial start up, set the pointer to 5 degrees before tdc then hook up a 6 or 12 volt bulb to the points side of the coil. Turn the dizzy till the bulb turns off then lock down the diz. With everything else hooked up, it should fire right up. Mine did. Quote Link to comment Share on other sites More sharing options...

Plymouthy Adams Posted April 5, 2019 Report Share Posted April 5, 2019 when installing the pump, align visually for the slot to be 7-1 then counter rotate the shaft one gear tooth, insert, the spiral mesh will now advance the slot to again be 7-1 installed...
