HKX, Inc., Hydraulic Kits for Excavators, the construction equipment division of Multi Parts Solutions (MPS), has released a new line of Wheel Loader 3rd Spool Auxiliary Field Installable Kits – its first line developed for wheel loaders. The kits gives equipment dealers and owners a way to add attachment capability to wheel loaders already on the lot or in the fleet, enabling use of a range of mounted tools, including rollout buckets, grapples, bucket screeners, snow blowers, brooms, mowers and hammers.
“Dealers have told us for years that lead time is the constraint, not the hardware,” said Robert Burnett, vice president and general manager of HKX. “A loader sitting on the lot is a versatile machine if you can equip it quickly. These kits let a dealer say ‘yes’ to a customer this month instead of pointing at a plant schedule, and they let that dealer stock a simpler machine that stays sellable to everyone.”

The kits use a bolt-on external valve design that mounts to existing OEM locations. Plug and play controls connect to the machine’s existing joystick and proportional control switch, with flow adjustment made through the operator’s own monitor rather than an added switch box in the cab. Adjustable relief protection is provided on the added function.
Each kit ships pre-assembled with a complete installation and parts manual, backed by a one-year warranty, lifetime technical support and same-day availability on nearly all replacement parts. Optional jumper hose sub-kits with quick-disconnect terminals are available, and fourth and fifth spool options are in development.
Coverage at release includes the Komatsu WA200-8, WA270-8, WA320-8 and WA380-8, with the WA475-11 to follow.
