Re: {Chrysler 300} Engine mounts

[John Grady <jkg@xxxxxxxxxxxxxxxxx>]

i was wondering what to do on these as even brand new the rubber bond is / was dicey , kind of a crummy design ( sorry purists) .

Once “rebuilt” , they may look nice but very deficient as a motor mount if you get on it .

I remember “ frankenmount “ back in old  days  a long bolt ( 5/16?) right through rubber and steel on drivers side ( that is the side which lifts) left a little loose will grab  it  .

on another project i adapted 70’s type A block spool mounts to hemi as one side on mount  fits block at least but need to weld to make frame side fit .  Spool type cannot break off . The hemi “ round cylinder” type can lift up and off under abuse ( whats that ? ) 

I do not know later cars  well enough,  but probably some years (  ?70’s ) had B block with spool mounts?

maybe can adapt  ?

 I do not trust “ rebuilt” etc and if it fails can be a real horror show , motor jumps up , breaks every thing .

? what to do ? small guy rebuilder cannot vulcanize rubber to steel  like factory did and even then it was marginal.

There was s company ? Stephans? that made a sandwich style mount interleaved rubber with steel that fixed this . Not sure if still around?   

 good subject …

In addition to checking the mounts, perhaps a braided steel rope someplace to the subframe so the unit cannot move forward would not be a bad idea 😊

Subject: {Chrysler 300} Engine mounts

 

For those of you tooling around in a C body (65-68 300 and related) I have discovered it is easy to drive around for years with broken engine mounts without knowledge thereof. I remember as a kid just how easy it was to rip engine mounts (and U joints) from any car with a 413 or 440.

But as an adult with a more sympathetic right foot I’ve driven a 68 New Yorker for quite a while with its 440 merely perched rather than mounted in the engine room.

 

I discovered this two weeks ago when a 10 year old Honda operated by a 17 year old girl failed to look up from her phone and use her brakes - was instead stopped by the rear bumper of said New Yorker which was pushed into a second 10 year old Honda in front of me.

 

Upon impact was the obligatory coolant loss with steam and a clanking fan but absolutely no sheet metal damage anywhere. How could this be?

 

The engine and transmission moved forward at impact into the fan. Had no idea the mounts were shot.

 

Check those mounts.
