Vibration Damper/Harmonic Balancer

[steveplym]

Thanks for the tips Lou and Don. Looks like it will be fine less the damper. Glad you got it going Mike. Now it won't put a "damper" on your day anymore.

Pun intended. Sorry, couldn't resist.

In 1949 the Dodge has a damper on the coronet but no damper on the (cheep) wayfarer.

Don't know if this is the correct place to ask a question.

My 48 Plymouth coupe crank pulley has no center bolt holding it in place.

 

When I was replacing the frt. eng. mt. I pryed lightly on the pulley & noticed it slid forward.

The keyway is loose and I can move back & forth slightly & the only thing holding the pulley from flying off is the 12 volt alt. belt.

 

I also have a vibration in neutral when I rev the eng. up

All Mopar flathead 6's had a large bolt holding the crank flange/pulley onto the crank..........I wouldn't run the engine till I got the bolt on.........from memory its 1 & 13/16th.........andyd

I'm just guessin but it seems that the crank pully was installed on 218 engines while the bigger ones got the hub/damper/pulley like Don runs....anyone know for sure.  My 218 runs nice and smooth with just the pully hub arrangement.

My '33 PD has a damper on its original 190 cu. in. engine. At least in the early 1930s the DeLuxe model Plymouths got the damper but the Standard/Business/Roadking models got just a pulley.

Thanks for the info. I think the car has been driven for yrs. without the bolt. Not by me but the previous

owner. I found a bolt at work. 5/8" 1/1/2 inch long NF thread. Can't tell if it fits. Will need to remove the radiator to access. May get rid of the vibration too.

 

I didn't realize it was missing until I changed the rubber mt. It was metal to metal. thought that was

the cause of the vibration. Wrong.
