Note 1
Seal sleeve, item 44 is no longer used and is not available as a replacement part. For units purchased with seal sleeves requiring
replacement contact your Ingersoll-Rand distributor or factory.
Serial numbers A1480801 and above will have new reduction gear 28744, drive shaft 28738 and sun gear 28826. Winches with
Serial numbers below A1480801 needing reduction gear parts will have to purchase new reduction gear and drive shaft 28738.
Service kits are still available.
These parts also come in a cold weather version. For winches with a -C in the model code, adding CH to the end of these part
numbers is required to retain winch certification. Example: Order Drive Shaft (item 35) part number 10579 as part number
10579CH.
Refer to UPRIGHT ASSEMBLY PARTS LIST, DRUM ASSEMBLY PARTS LIST and SIDE RAIL ASSEMBLY PARTS
LIST for parts information. RH = Right Hand Side, LH = Left Hand Side as viewed from the winch motor end. Inboard is end
closest to motor; outboard is end farthest away from motor.
