Testing Includes:
Visual Inspection
Visual / Finish
Paint / Rubber Appearance
Weld Integrity
Dimensional Verification
Dimensions tested / approved using CMM (machine which takes readings in six degrees of freedom and displays these readings in mathematical form)
Elastomer / Durometer Tested
Rubber Hardness Check
Every shipment inspected thoroughly
Supplier verification on site
Rubber Tensile Strength tested
Strip sample and test of rubber processing
Supplier must submit test report and sample from every batch
On-site audits to verify process capabilities
Thermogravimetric Analysis
TGA / Rubber Compression Tests (changes in physical and chemical properties of mount materials are measured as a function of increasing temperature (with constant heating rate), or as a function of time (with constant temperature and/or constant mass loss))
Rheometer / Vulkameter tested (measure the way rubbers respond to applied forces)
Supplier must submit test report and sample from every batch
On-site audits to verify process capabilities
Tips & Tools For The Repair
Inspect Motor Mounts (found in the "Engine" category) for signs of wear. Transmission and Motor Mounts typically wear at the same rate
The original mount bolts can be difficult to remove. Apply Penetrating Oil and have a Breaker Bar handy to help break them loose
Find a solid part of the transmission to place the Jack under. Do not use the fluid pan, it is not strong enough to support the weight of the transmission
Apply Blue Threadlocker to mount bolts prior to installation to prevent backing out due to the high vibrations transmission mounts are subject to
