The Yale BMZ range provides hydraulic puller sets for maintenance and repair work. Three capacities (10, 15 and 23 tonnes) are available as puller-only sets (BMZ-1000, BMZ-1500, BMZ-2300) or complete sets with Yale hydraulics (BMZ-1010, BMZ-1510, BMZ-2311). Yale describes the BMZ as suitable for removing and installing interference-fit parts including gears, couplings, bearings, wheels, pulleys, axles, shafts, brake drums and other press-fit components.
Hydraulic puller sets with separate or integrated Yale hydraulics
Yale documentation states the harder the pulling force, the tighter the grip of the jaws. Yale notes longer jaws up to 1000 mm are available on request. The complete sets (BMZ-1010, BMZ-1510, BMZ-2311) include high-quality components from Yale's standard hydraulic program with long-life hydraulic cylinders manufactured from chromium-molybdenum steel, two-stage quick-action hand pumps, and a high-pressure hydraulic hose (2 m) with quick coupler. All complete sets are supplied in metal box HPK-10 or wooden case, ready to use. The pressure gauge set GYA-63 is included in the scope of delivery.
Suitable Applications
Per Yale: removing or installing interference-fit parts including gears, couplings, bearings, wheels, pulleys, axles, shafts, brake drums and other press-fit components. Industries: maintenance and repair across general engineering.
Tools, pumps and hoses must share pressure rating and coupler type. Confirm all three before ordering rather than discovering the mismatch on site.

Frequently Asked Questions
Q: Puller-only or complete set?
Complete sets (BMZ-1010, BMZ-1510, BMZ-2311) include all Yale hydraulics needed - cylinder, hand pump, hose, gauge. Puller-only sets (BMZ-1000, BMZ-1500, BMZ-2300) are for users who already have compatible Yale hydraulics.
Q: What's special about the BMZ-2311?
Yale specifies the BMZ-2311 has radially adjustable pulling arms that can be locked at any position. Optional BMZ-2308 (400 mm reach) and BMZ-2309 (500 mm reach) arm extensions are available.
Q: Can I get longer pulling arms?
Yes. Yale notes longer jaws up to 1000 mm are available on request.
Q: How are complete sets supplied?
Yale supplies complete sets in metal box HPK-10 or wooden case, ready to use with GYA-63 pressure gauge set included.
