Description
This genuine OEM tool is explicitly engineered for Yanmar’s popular mid-range marine diesels. It is fully compatible with the following engine models:
- 3-Cylinder: 3JH40, 3JH4E
- 4-Cylinder: 4JH3, 4JH45, 4JH110
How to verify: Look at your replacement impeller. If the center hub has internal threads, this is the exact tool designed to screw into it.
This turns a frustrating job into a 30-second task. Standard universal slide-hammers or pliers often damage the delicate brass pump housing or shred the rubber blades. This factory tool uses a damage-free mechanical draw:
- Thread: You hand-screw the main collar (Puller A) directly into the threaded center of your impeller.
- Jack: You turn the integrated M10 jack screw clockwise against the pump shaft.
- Extract: The mechanical leverage smoothly draws the stubborn, salt-encrusted impeller straight out without any prying.
When you order part number 129671-92110, you receive the complete three-piece factory assembly ready for use:
- The Puller Body – The threaded collar that locks into the impeller.
- The Jack Screw – The heavy-duty M10x40 bolt that drives the extraction.
- The Washer – To prevent binding during rotation.
