Isoflex IFV90-20S Engine Mount for John Deere and Other Marine Engines

Isoflex self-aligning adjusters increase the mount's stud strength up to 3x by providing a compression fit. Adjusters allow up to 4 degrees of bracket-to-bearer misalignment to reduce point loading.

  • Stud size 3/4" (M20)
  • 5" mounting center (127mm)
  • Minimum free height 3.94" (100mm)
  • Replaces factory mounts for John Deere, Fiat-Iveco, Doosan, Gardner, MAN, Perkins Sabre, Yanmar, AGCO SISU
  • Provides at least 85% vibration isolation at worst case engine idle (4cyl and above) = less equipment fatigue, maintenance and associated noise
  • Encapsulated core allows for fine tuning of inverted stiffness
  • Resilient element co-polymer resists fuel, oils, water and hydraulic fluids
  • Hold-down bolt slots can be rotated to any direction for easier installation
  • Fail safe
