MTB170 Seal Kit for Hydraulic Breakers: Reliable CFW NOK Repair Kit for INAN Makina

The MTB170 seal kit (CFW NOK) is a comprehensive hydraulic rock hammer oil repair kit designed to restore sealing integrity, reduce downtime and extend the service life of INAN Makina MTB series excavator breakers. OEM-grade components—diaphragms, pistons seals, O-rings and wear bushings—ensure pressure containment and consistent impact performance for construction and demolition fleets.

How to choose the right seal kit for your hydraulic breaker?

How to verify compatibility between the MTB170 seal kit and my breaker model?

Confirm model matching by cross-referencing the breaker serial/model number with the kit's compatibility list; the MTB170 seal kit is engineered specifically for INAN Makina MTB series breakers. If serials differ, measure piston diameter and ring groove profiles to ensure the CFW NOK seals and O-rings match bore and shaft tolerances.

How to evaluate seal material and temperature ratings for your operating conditions?

Select seals rated for your hydraulic fluid and ambient extremes; CFW NOK materials in this MTB170 seal kit are formulated for mineral-oil hydraulics and continuous operation typically between -20°C and 120°C. For synthetic fluids or higher thermal loads, specify Viton/FKM variants and check material data sheets for fluid compatibility.

How to decide between full kits and partial repair sets?

Choose a full MTB170 seal kit when downtime must be minimized and internal wear is unknown; full kits replace diaphragms, pistons, O-rings and wear bushes for a comprehensive rebuild. Partial sets are cost-effective for targeted leaks, but risk repeat service if wear extends beyond the replaced components.

What causes hydraulic breaker leaks and how can the MTB170 seal kit solve them?

What causes piston and cylinder oil leaks in an MTB-series breaker?

Common causes are worn piston rings, hardened diaphragms and scratched cylinder bores from contaminated oil or abrasive chisels. The MTB170 seal kit replaces degraded CFW NOK seals and pistons to restore dynamic sealing and prevent pressure loss that reduces impact energy.

What causes external oil seepage around tool retainers and side bolts?

External leaks often stem from damaged O-rings or improper torque on through bolts; replacing O-rings and re-torquing to manufacturer spec eliminates leak paths. Using the MTB170 seal kit's correct-size O-rings and following torque/assembly procedures restores external sealing integrity.

What causes accelerated wear on wear bushes and valves?

Abrasive dust ingress, lack of lubrication and improper chisel alignment accelerate wear; replacing wear bush and inspecting valves during service mitigates the root causes. The MTB170 kit includes wear components to restore alignment and reduce metal-on-metal wear.

How to perform a reliable seal kit replacement on an MTB170 breaker?

How to prepare the breaker and workspace before installing the MTB170 seal kit?

Depressurize the hydraulic system, remove the breaker from the carrier, and clean the exterior to prevent contamination entering the tool during disassembly. Organize the MTB170 seal kit components and use clean shop towels and protective gloves to maintain component cleanliness during assembly.

How to inspect internal parts and what to replace beyond the seal kit?

Inspect piston surface, cylinder bore, valve spool and retainer bars for scratches or pitting; replace components outside wear limits to avoid premature seal failure. Measure piston diameter and check wear bush clearances; if runout or wear exceeds manufacturer tolerances, plan a component-level rebuild in addition to installing the MTB170 seal kit.

How to torque and test the breaker after seal replacement?

Reassemble following specified torque values for through bolts and side bolts, then bench-test the breaker at low pressure before full operational trials. Perform a leak check at rated pressure and run the breaker for several cycles to ensure the MTB170 seal kit has seated correctly and that impact energy is restored.

Why choose OEM-grade MTB170 seal kits from Huilian Machine?

Why does OEM quality matter for hydraulic breaker seals?

OEM-grade seals are manufactured to exact tolerances and compound specifications, ensuring pressure containment and long-term reliability in high-impact hydraulic systems. Huilian Machine’s MTB170 seal kit uses proven CFW NOK equivalents to match factory fit and performance for INAN Makina MTB breakers.

Why is technical support and traceability important when purchasing seal kits?

Traceability ensures you get the correct revision of seals and materials; Huilian Machine provides part documentation and post-sale technical support for installation guidance. This reduces installation errors and helps maintain warranty and service records for fleet management.

Why consider global supply and stocking strategy for spare parts?

Having MTB170 seal kits stocked locally or via a trusted supplier reduces machine downtime and costly transport delays. Huilian Machine exports to over 90 countries and supports distributor partnerships to ensure timely availability of hydraulic breaker spare parts.

Authoritative resources for best practices include the technical overview of hydraulic breakers (Hydraulic breaker - Wikipedia), general excavator systems reference (Excavator overview - Wikipedia), and international quality management guidance (ISO 9001 quality management information), which support structured maintenance and quality procurement decisions.

Frequently Asked Questions

What is the MTB170 seal kit compatible with?
The MTB170 seal kit is designed for INAN Makina MTB-series hydraulic breakers, matching standard piston and diaphragm dimensions. Verify the breaker model and serial number before ordering.

How long does a full seal kit replacement take?
A professional technician typically completes a full MTB170 seal kit replacement and bench testing in 3–5 hours. Time varies with condition, tooling, and whether additional parts need replacement.

Can I use the MTB170 seals with synthetic hydraulic fluids?
Yes, if you choose the seal compound rated for synthetic fluids; request FKM/Viton variants for compatibility. Confirm material compatibility with operating temperature and fluid specifications.

Why is the CFW NOK specification important?
CFW NOK denotes compound and profile standards used for dynamic and static sealing in breakers, ensuring oil retention under impact loads. Using equivalent CFW NOK seals restores original sealing performance.

How often should I replace seals on high-use breakers?
Replace seals every 800–1,200 operating hours under heavy-duty cycles, or sooner if leaks appear. Regular inspection at 100–200 hour intervals helps catch wear early.

Is professional installation necessary for the MTB170 seal kit?
Professional installation is recommended for optimal sealing and torque control; experienced technicians reduce rework risk. Huilian Machine provides installation guidance and technical support for customers.
