The Remco RMC151651 RollMax coupler connects your tractor PTO shaft to the R880 series rollmax pump, handling both 540 and 1000 RPM PTO speeds in a single durable cast aluminum and zinc assembly. Whether you run a modern 1000 RPM tractor or an older 540 RPM unit, this coupler gives you one part that covers both configurations -- no guessing, no wrong-speed adapters.
Most farm tractors and utility vehicles run either a 540 RPM or a 1000 RPM power take-off shaft. Buying the wrong speed-specific coupler is a common and frustrating mistake. The RMC151651 solves that by supporting both 540 and 1000 RPM outputs on a standard 15/16 in. PTO shaft -- making it the right call for mixed fleets, rental equipment, and anyone who isn't 100% certain of their PTO speed.
This coupler is the interface between your tractor's PTO and the Remco R880 series rollmax pump. It seats on the pump input shaft and locks in place with set screws. The cast aluminum and zinc construction keeps weight low while delivering the rigidity needed at PTO torque loads.
Compatible with both 540 RPM and 1000 RPM tractor PTO outputs -- no separate adapters needed.
Precision-bored to fit the standard 15/16 in. PTO input shaft used on R880 series RollMax pumps.
Secures firmly to the shaft via set screws -- no keyway dependency, straightforward installation.
Lightweight alloy construction resists corrosion and holds up under continuous PTO-driven pump operation.
The RMC151651 is designed specifically for the Remco R880 series RollMax pump lineup. It is the same coupler included in the R880C-TAK complete pump kit and is also available here as a standalone replacement part. If your original coupler is worn, damaged, or lost, this is the correct replacement.
If you already purchased the Remco R880C-TAK complete RollMax pump kit, this coupler (RMC151651) was included in that kit. This listing is for the standalone coupler -- useful as a spare, a replacement, or for building a custom pump assembly from individual components.
Installation is straightforward for anyone familiar with PTO-driven equipment. Slide the coupler onto the R880 pump's input shaft, align set screw locations, and tighten securely. Always confirm PTO is disengaged and tractor is off before mounting or removing the coupler.
Remco's RollMax R880 series pumps are PTO-driven roller-vane transfer pumps used for liquid transfer in agricultural, RV, and utility applications -- including transferring fuel, water, and other compatible fluids at the field or job site. The coupler is the mechanical link between the tractor and the pump, and its condition directly affects pump performance and safety.
Inspect the coupler set screws periodically for tightness, especially during the first several hours of operation on a new installation. A loose coupler under PTO load can damage the pump shaft or the coupler bore. Keep a spare set of appropriately sized set screws on hand when operating in remote field conditions.
