R & D Marine Shear Loaded “Super Mounts”, Yanmar, 80-410 lbs

• R & D Engine Mount Catalog

The R&D Engine Mounts are specifically designed for the rigors ofmarine, industrial, commercial, and heavy equipment applications.These engine mounts are pre-loaded to provide a dampening effectwhen encountering upward or downward pressure. Most R&D mountsare shear loaded to absorb forward and reverse thrust, yet soft enoughto isolate engine vibrations from the surface where they are mounted.To assist in the ease of installation, the mounts have nuts to adjust theheight. The slotted holes in the base of the mount assist in alignmentand installation.To help increase the longevity of the mounts, all steel parts are zincplated and passivated to limit corrosion. The threads of the stud arerolled and reduce the possibility of shearing the stud. This technologyproduces a significantly stronger thread than possible when thematerial is cut away in conventional cut-thread die methods. Morespecifically, the thread rolling (cold forming) process strengthens thethread in three ways: tension, shear, and fatigue resistance. The rubbercomponent is covered by an oil shield to protect the rubber frompetroleum based products.
