Product Overview

The 6815953 hydraulic cylinder seal kit is an aftermarket rebuild set supplied by DJF Seals for the blade (dozer) cylinders of Bobcat compact excavators. Note that 6815953 is the genuine Bobcat part number of the blade lift cylinder itself — Bobcat Company lists “Cylinder | 6815953”, and aftermarket suppliers (Hydraulic Cylinders Inc, Aztec Hydraulics) sell the matching blade cylinder and its seal kit under this number. The seal kit most commonly paired with cylinder 6815953 is 6816533 (theoringstore/OSK: “Model 435 Excavator Blade Cylinder Seal Kit For Cylinder: 6815953”). The kit typically contains piston seal, rod seal, wiper, O-rings and backup ring. DJF Seals supplies it factory-direct for heavy-equipment parts distributors, repair shops and fleet maintenance teams.

Verified Application

Blade (dozer blade lift) cylinder of Bobcat compact excavators — consistent across all independent sources found: Hydraulic Cylinders Inc (“Replacement Blade Lift Cylinder Bobcat 337/341/435 | PN 6815953”), theoringstore/OSK (“Blade Cylinder Seal Kit … For Cylinder: 6815953″) and HW Part Store (blade seal kits for Bobcat 435, 435D, 435G). A sourced dimension cross-check is available: 1-3/4″ rod x 3-1/4” bore for cylinder 6815953 (theoringstore) — the same values shown on this page; verify on the cylinder before ordering.

Replacement Scope

One blade-cylinder seal set per kit — piston seal, rod seal, wiper, O-rings and backup ring as supplied (contents consistent with the matching 6816533 kit listed by theoringstore/OSK). The kit restores the sealing function of a dozer blade lift cylinder on a Bobcat compact excavator. Confirm the cylinder and machine model before purchase.

Fitment Verification

Machine fitment verified across independent sources: Bobcat 337, 341 and 435 compact excavators (Hydraulic Cylinders Inc); Model 435 (theoringstore); 435, 435D and 435G (HW Part Store). CONFLICT NOTE: the page claims “Bobcat Excavator 341G Blade”, but the “341G” designation was not found in any independent source — Bobcat 341 is documented as “341” in parts catalogs (777parts), and the blade cylinder 6815953 is referenced on 337, 341 and 435 machines. Confirm your exact machine series before ordering. Also note that 6815953 is the cylinder number; the seal kit number commonly paired with it is 6816533 — check which reference number your supplier or parts system uses.

Factory Inspection & Packing

Every DJF seal kit is checked against its part number and application list before packing: seal elements are inspected for visible defects, counted against the kit list, and packed in sealed PE bags with a parts label. Kits are then packed into export cartons for warehouse or direct shipping. OEM/ODM branding and custom packaging are available on request.
