Set of 2 Hydraulic Cylinder Seal Kits 6803329 Fits Bobcat Lift 642 742B 751

What This Is

This is a set of two (2) new aftermarket hydraulic cylinder seal kits for Bobcat skid steer loaders. Each kit contains the full set of rod and piston seals, O-rings, wipers and back-up rings needed to reseal one hydraulic cylinder, so a single order lets you rebuild a pair of cylinders or keep a spare on the shelf. These are quality aftermarket kits and are not Bobcat OEM branded.

Fitment

This seal set services the lift (boom) cylinders on Bobcat 700, 720, 721, 722, 730, 731, 732, 741, 742, 743, 743DS, 751 and 753 series skid steer loaders. It is the same common Bobcat seal kit that also fits the tilt cylinders and several attachment cylinders on these machines, which is why Bobcat lists a wide loader range for the number. Because Bobcat used more than one cylinder design across production years and serial breaks, always verify the kit against your actual cylinder before ordering.

Specifications

The cylinder these seals fit uses a 1-1/4 in rod diameter and a 2 in bore. Seal kits are cylinder-specific, so confirm your rod and bore measurements match before installing. You receive two (2) complete kits per order, each sufficient to reseal one cylinder.

Cross-Reference and Supersession

This kit replaces Bobcat OEM seal kit part number 6803329. Bobcat has since superseded 6803329 with current part number 7137769, which is the listed direct replacement; both numbers refer to this same seal kit.

Ordering Guidance

Order one kit per cylinder you intend to reseal; this listing ships two kits. Because the seal set covers lift, tilt and attachment cylinders across several model years, match the rod (1-1/4 in) and bore (2 in) to your cylinder, or cross-check your machine's serial number against the Bobcat parts catalog, before purchasing. If your cylinder measures differently, a different seal kit is required.
