If you work on heavy equipment engines undercarriage parts, you know the moment a track pin refuses to move. Hammering, heating, and prying can eat up an afternoon and still leave you stuck. That's where a dedicated track link pin press comes in, and the HayWHNKN model is one purpose-built option. For USD 1,969.00, this 100T electric hydraulic press uses a 220V electric pump to drive a hydraulic jack forward, smoothly pushing the pin out of the chain. It's a specialized maintenance tool for crawler undercarriage work, not a general-purpose shop press.
HayWHNKN Track Link Pin Press
Quick Verdict
The HayWHNKN Track Link Pin Press is a serious, heavy-duty machine for shops that regularly rebuild crawler excavator undercarriages. Its 100T capacity provides substantial force, and the electric-hydraulic design removes the manual swinging of a sledgehammer. If you have 220V available and space for a heavy, dedicated press, it can make track chain disassembly more controlled and less physical. If you only break a track a couple of times a year, the weight, footprint, and cost may be hard to justify.
Who It Suits
This press is built for equipment workshops, fleet maintenance facilities, and technicians who service crawler excavators as a core part of their work. It suits anyone who needs a repeatable method for removing pins that are seized or worn into place. The screw diameter options of 40mm and 50mm (1.57in and 1.97in) give you a degree of adjustability for different pin sizes, and the 1000mm screw length offers a good working reach. If you're doing undercarriage rebuilds on a regular basis, this tool can reduce physical strain and speed up the process.
What Stands Out from the Listed Details
The headline feature is the 100T hydraulic force generated through an electric pump. Instead of relying on impact, the machine applies steady, controlled pressure to move the pin shaft. The screw length of 1000mm gives you room to position the press, and the cylinder stroke of 100mm (3.937in) is enough to push a pin clear of the chain link. The listed weight is substantial: 284.17lbs plus 105.6lbs, so together you're looking at roughly 390lbs of equipment. That tells you the build is heavy-duty, but it also means you need to plan for moving and mounting it. This is a new unit, so you're getting a fresh tool rather than a used one.
Meaningful Trade-offs
The most obvious trade-off is electrical: the machine is rated for 220V. If your shop doesn't already have a 220V outlet near your work area, you'll need to add one or run a dedicated circuit. The weight is also a consideration. At roughly 390lbs combined, you'll need a hoist, forklift, or several strong helpers just to get it into place. And because the cylinder stroke is just 100mm, you're limited to pin removal tasks that fit within that range; it's not a multi-purpose press. For shops that only handle occasional undercarriage work, the cost and space could outweigh the benefit.
Bottom Line
If you're in the business of servicing crawler excavator undercarriages, the HayWHNKN Track Link Pin Press offers a practical, power-assisted way to remove track pins. The 100T capacity, electric-hydraulic operation, and 220V pump make it a workshop anchor for track chain disassembly. The price of USD 1,969.00 is a real investment, and you'll need the electrical setup and physical handling capacity to support it. For a shop that does this work daily, it can buy back time and spare your crew's backs. For occasional users, the weight and power needs are significant hurdles. Look at your job frequency and shop infrastructure before you commit.
