Onan Small Engine Replacement Kits
When the original Onan powerplant in a tractor, trencher, or skid steer finally calls it quits, parts are scarce and rebuilds cost time you don’t have. A purpose-built repower kit swaps aging iron for modern horsepower, so your machine keeps earning its keep instead of sitting in the shed.
At Repower Specialists, we’ve developed engine kits that replace many discontinued Onan models, from B43E and B48G series blocks to P220 and P224 performers. Each kit pairs your equipment with a current-production Honda, Kohler, or Vanguard engine chosen for comparable or better output and durability.
ONAN ENGINE UPGRADES INCLUDE:
Ditch Witch 255SX Onan P224 to Honda GX630 / GX690
John Deere 318 Onan Engine to Honda GX630 / GX690 Kit
John Deere 420 Onan B48 Performer P220 to Honda
New Holland L250 Skid Steer Onan
Installing a fresh engine helps eliminate hard starts, oil leaks, and fuel-consumption spikes, keeping older equipment productive without hunting down obsolete Onan parts.
