Furukawa FX35 Breaker Seal Kit 902307-920010 | FRD Hammer Repair Kit

Product Description

902307-920010 Hydraulic Breaker Seal Kit — Furukawa FRD FX35 Excavator Hammer

The FX35 is the largest model in Furukawa’s small breaker series (Fx15a/Fx25a/Fx35a), sitting just below the mid-size Fx125 line. At roughly 146 kg (about 320 lbs assembled) with an operating pressure of 120–150 bar and a striking rate around 1,300 blows per minute, the FX35 is built for jobs that need more punch than the smaller FX15/FX25 but still need to fit on skid steers, mini excavators, and compact utility loaders — typical uses include road repair, foundation removal, and general excavation work.

Like the rest of the small series, the FX35 uses a mono-block body with no thru-bolts and no diaphragm — this eliminates two of the most common maintenance items on conventional breakers, but it also means all sealing responsibility is concentrated in the piston and valve chamber of a single-piece housing. Under the FX35’s higher blow rate and pressure range compared to the FX25, seal wear tends to show up faster if OEM-spec materials aren’t used, since there’s no separate front-head assembly to isolate wear.

Key Features & Benefits

Demolition-Grade Material Durability

Formulated with premium-grade Polyurethane (PU) and heavy-duty Nitrile Rubber (NBR) compounds rated to handle the FX35’s 120-150 bar operating pressure and 1,300 bpm impact rate without premature breakdown.

Precision Zero-Leakage Fitment

Matched to the FX35’s mono-block internal profile to eliminate internal oil bypass and cylinder drift — critical given the design has no separate front-head to compensate for a slightly-off seal fit.

Complete Hammer Rebuild Package

Includes a fully matched set of step seals, buffer seals, dust wipers, quad rings, and O-rings for a complete cylinder overhaul in one kit.

Extended Service Life & Reduced Downtime

Thermal stability suited to sustained operation at the FX35’s higher blow rate compared to the FX15/FX25, reducing the frequency of unplanned rebuilds.

Important Fitment & Ordering Note

The FX35 and FX35a share the mono-block platform but may differ in seal profile across production revisions. Since this design has no separate front-head to allow tolerance for a near-fit seal, please verify your breaker’s model plate and serial number against OEM specifications before ordering, or contact our team for confirmation.
