Sun Coast Cycle Sports has used parts available for the Kubota RTV1100, a cab-equipped diesel utility vehicle produced from approximately 2008 to 2013. Powered by Kubota's D1105 three-cylinder liquid-cooled diesel engine producing 24.8 hp at 3,000 rpm from 1,123cc of displacement, the RTV1100 was the first Kubota UTV to offer a fully enclosed cab with optional heat and air conditioning. Parts from donor units are individually inspected, cataloged with unique SKUs, and ship from our Florida location.
RTV1100 platform and parts compatibility
The RTV1100 shares its D1105 diesel engine with the RTV1140/CPX and RTV-X1140 models. Engine internals, filters, and fuel system components interchange across all 1100-class Kubota UTVs. The RTV1100 used the same three-range VHT hydrostatic transmission as the original RTV900. The RTV1100C was the cab model with heating and air conditioning, while the base RTV1100 had an open ROPS. Body panels, cab components, and glass are specific to the RTV1100 and do not fit the later RTV-X1140.
Common RTV1100 failure points and replacement parts
Cab seal and window issues: The enclosed cab can develop air and water leaks around door seals, window gaskets, and the windshield frame. Replacement seals restore cab integrity.
HVAC system: The AC compressor and heater core on cab models are common maintenance items, especially on units operated in extreme heat or dusty conditions. Condenser cleaning is critical.
Cooling system: Like the RTV900, the RTV1100 has a mid-mounted radiator susceptible to debris buildup. Regular cleaning prevents overheating.
Hydrostatic transmission: The same VHT-related shifting concerns as the RTV900 apply. Proper technique (full idle before shifting) prevents damage.
Commonly replaced RTV1100 parts
- Cab door seals, window glass, and gaskets
- AC compressor, condenser, and heater core
- Radiator and cooling system components
- Drive belt and transmission parts
- Fuel injectors and glow plugs
- Seats and interior trim panels
- Bed hydraulic components and tailgate hardware
Frequently asked questions
Q: Will RTV1140 parts fit an RTV1100
The D1105 engine is shared across the RTV1100, RTV1140/CPX, and RTV-X1140, so engine internals and consumables interchange. Chassis and body components differ between models. The RTV1140/CPX is a wider vehicle with a convertible passenger configuration not found on the RTV1100. Frame, suspension, and body panels are model-specific.
Q: Does the RTV1100 have AC
The RTV1100C cab model was available with factory air conditioning and heat. The base RTV1100 with open ROPS does not have climate control. AC components are specific to the cab model and require the enclosed cab for installation.
The 1100-class Kubota RTVs represented a significant step up from the 900 series, adding a larger 1,123cc diesel engine, greater payload capacity, and the option for a fully enclosed cab with climate control. The D1105 engine produces 24.8 hp, a meaningful improvement over the D902's 21.6 hp, along with substantially more torque for heavy hauling and towing applications. The RTV1100 was Kubota's answer to customers who needed year-round comfort in a utility vehicle, particularly for municipal, campus, and agricultural use in extreme weather.
Q: What is the payload capacity of the RTV1100
The RTV1100 has a cargo bed payload capacity of approximately 1,102 lbs and a towing capacity of approximately 1,300 lbs. The cab model (RTV1100C) weighs more than the open ROPS model, which slightly reduces effective payload. Always account for passenger weight when calculating cargo capacity.
Q: What coolant does the RTV1100 use
The Kubota D1105 engine uses Kubota Super UDT or equivalent long-life coolant. Do not mix coolant types. Flush and replace coolant per Kubota's maintenance schedule, typically every 2 years or 1,000 hours.
