The (“Dual Flex”) DF-4420 Series of heavy duty mountings is a twin
stud double mount designed principally for diesel engines in excess of
2,800 lbs. up to 5,600 lbs. in weight. These mounts are generally used
on the “heavy (marine transmission) end” of the engine along with
DF-4400 Series mounts on the front of the engine. Durable oil and fuel
resistant elastomer element. Low profile mount - requires only 3 3/8”
minimum clearance from casting base to top of leveling nut. Fail safe
design - bottom pad prevents excessive impact. Easy installation with
full 1” threaded studs for vertical height and slotted casting for
horizontal adjustment. Mounts come complete - furnished with three
nuts: leveling, locking and secondary lock. Aluminum base cast with
1/2” slotted mounting holes for 1/2” bolts or lag screws on 9” centers.
All steel parts are zinc plated for corrosion resistance. Available in four
size ratings (shown below) dependant on engine/powertrain package
weight.
The patented Bushings, Inc. “Dual Flex” Marine Engine Mount design
provides outstanding vibration isolation control across the three
(longitudinal, lateral, and vertical) fields of vibratory motion.
Construction of the mount gives a soft cushioning effect under normal
loads, as mount loads increase across the operating range, shear resistance
grows quickly providing smooth operation with a small amount of
deflection.
