Product Description
The WE-272661 is a complete hydraulic unit for Wesco CPI model manual pallet jacks (5500 lb capacity). This assembly includes the entire hydraulic pump mechanism: the main pump cylinder and piston, internal valves (lifting and lowering valves), pump handle socket, and fluid reservoir – all pre-assembled into a single unit.
It is an OEM-spec pump designed to drop into the Wesco CPI series pallet trucks (and also compatible with the CP3 series Wesco jacks, which use the same pump).
If your pallet jack is no longer lifting or has a damaged pump, replacing it with the WE-272661 unit will restore full lifting capability. The pump comes ready for installation – simply transfer your jack’s handle assembly to the new pump, fill it with hydraulic oil, bleed the system, and your Wesco pallet jack will be back to raising loads.

Frequently Asked Questions
Q: Does the pump come pre-filled with hydraulic oil?
A: No, this replacement pump is typically shipped dry (without oil). You will need to fill the pump reservoir with the appropriate hydraulic fluid after installation.
Q: What type of hydraulic oil should I use for this pump?
A: Wesco manual pallet jacks (and most pallet jacks in general) use a standard ISO VG 32 hydraulic oil (which is a light hydraulic oil) or an equivalent.
Q: Should I try to rebuild my existing pump with a seal kit or replace it entirely?
A: It depends on the condition of your pump. If the jack has a minor leak or has gradually lost lifting power, a seal kit (such as WE 270061) can often resolve those issues at a lower cost. However, if your pump cylinder is scored, the ram is bent, or the jack drops even after the seals are replaced, then the damage extends beyond the seals. In such cases, replacing the entire pump assembly is the most reliable solution.
Q: Are new seals and O-rings already installed in this pump?
A: Absolutely. The pump is shipped as a fully assembled, brand-new unit with all seals in place.
Q: Is any adjustment or calibration needed after installing the new pump?
A: Generally, the new pump is pre-calibrated and preset from the factory. The internal overload (relief) valve is already adjusted to the correct pressure for 5500 lb capacity, and the lowering valve is built in. After installation, you may need to adjust the linkage that connects the release (lowering) lever to the pump’s release valve.
