FAQ

Q1: How do I know if this 7135-573 repair kit fits my injector?
A: You must first remove the injector from the engine and locate the part number stamped on the injector body. If the number matches 7135-573, 28229873, or 33800-4A710, then this kit is the correct component for your repair. It is a valve kit, not a complete injector.

Q2: What is included in the repair kit, and is professional installation required?
A: This kit includes the necessary valves and seals for rebuilding the injector. Due to the high precision required for common rail injectors, installation should only be performed by a qualified diesel technician using proper tools and a clean environment. Incorrect installation can lead to engine damage.

Q3: What is the advantage of using this repair kit versus buying a new injector?
A: Using a high-quality repair kit like this 7135-573 is a very cost-effective alternative to purchasing a brand new injector. It restores the injector to like-new performance by replacing the most common wear components (the valve), often at a fraction of the cost of a complete injector unit.
