Below are the formulas to use to determine the required pounds per engine mount.
Front Engine Mount
(W x 0.4) x 0.5 = lbs per mount
Back Engine Mount
(W x 0.6) x 0.5 = lbs per mount
W = weight of engine and gearbox
Example:
Total weight of engine and gearbox = 1,200 lbs.
Front Engine Mount
(1,200 x 0.4) x 0.5 = 240 lbs per mount
Back Engine Mount
(1,200 x 0.6) x 0.5 = 360 lbs per mount
