I have a failed engine mount and in the process of changing it out thought a breakdown of the components within may be of interest.
pics show the main body, the bladder, valve plate and the upper section of mount.
Upper section normally includes the fixing stud which has separated on mine, hence the failure.
l am not sure what fluid is used in these mounts but some use a mix of water and glycol.

 

Thoughts about possibly replacing it with a solid polyurethane or rubber version of the same dimensions?

One assumes that some day these liquid filled things will no longer be available.

 

Charlie, I can tell you if looking for dimensions when you look up different parts of OEM mounts, there will only be the size of the shipping package.
The stores sometimes do have the length on their computer, best just have a buddy at Autozone and let you go through the boxes.
Or, be like me and just keep getting what looks like it might fit and buy it. Well, not really that bad but the only way sometimes.
