Browse aftermarket engine parts for skid steer loaders, compact track loaders, and compact tractors, including engine mounts, isolators, belt tensioners, rod bearings, glow plugs, and throttle hardware.
Match your part by OEM part number and engine model. Details are listed on each product page.
Engine parts match to the engine, not to the machine, and that distinction matters more here than on any other page. Compact loaders are commonly powered by engines built by a different manufacturer than the machine badge, so the correct part for a loader is often listed under an engine maker's number rather than the machine maker's. Common replacements include the belt tensioner replacing OEM 6735884, the tensioner kit replacing OEM 7302291, the engine mount replacing OEM 6661785, the isolator replacing OEM 6691082, the flange coupling replacing OEM 6670757, the glow plug replacing Kubota 1C010-65510, and the frost plug heater replacing Kubota 70000-92500.
Read the engine data plate rather than the machine decal when ordering internal parts. One machine model can carry more than one engine across its production run, and the engine number is what resolves it.
Mounts, isolators, and couplings carry the engine and absorb its vibration. They are rubber-bonded parts that soften and split with age and heat, and a failed mount announces itself as new vibration in the cab long before anything else fails. Left alone, that vibration travels into brackets, exhaust joints, and hose fittings, which is why a cheap mount is worth replacing early.
Internal engine hardware includes rod bearings, which are listed as separate part numbers per size grade. The number that fits depends on whether the crankshaft journal is standard or has been machined undersize, so measure or confirm the grade before ordering rather than matching the description alone. Cold start components cover glow plugs, block heater kits, and frost plug heaters, and belt drive components cover tensioners and tensioner kits that hold correct belt tension as the belt beds in.
