Bobcat / Doosan D34 DOC 2014-2020: OEM 7313995
Efficient Exhaust Emissions Treatment for Bobcat / Doosan D34 Engines (2014–2020)
What is it?
The Bobcat / Doosan D34 DOC, identified by OEM 7313995, is a Diesel Oxidation Catalyst (DOC) designed to reduce harmful exhaust emissions produced during normal engine operation. As the first stage of the aftertreatment system, it converts carbon monoxide (CO) and hydrocarbons (HC) into carbon dioxide and water while generating the heat required for downstream emissions components to function efficiently. This process helps the engine's complete emissions system operate as intended.
Why choose this DOC?
A properly functioning Diesel Oxidation Catalyst is essential for maintaining efficient exhaust treatment and supporting the operation of the entire aftertreatment system. The OEM 7313995 DOC is engineered specifically for Bobcat and Doosan D34 engines manufactured between 2014 and 2020, ensuring compatibility with factory-installed emissions components.
Over time, contaminants, soot accumulation, repeated regeneration cycles, and prolonged exposure to high exhaust temperatures can reduce catalyst efficiency. When this happens, operators may experience emissions-related warning lights, increased exhaust restriction, regeneration issues, or fault codes. Replacing a worn DOC with the correct OEM-matched component helps restore proper exhaust treatment and supports dependable operation of downstream emissions components.
Key Benefits
✅ OEM-matched Diesel Oxidation Catalyst for Bobcat / Doosan D34 engines (2014–2020)
✅ Converts carbon monoxide and hydrocarbons into less harmful emissions
✅ Supports proper operation of the complete aftertreatment system
✅ Helps maintain consistent exhaust flow throughout the emissions system
✅ Direct-fit design for simplified installation
✅ Built to withstand demanding construction and industrial operating conditions
Applications
This DOC is designed for Bobcat and Doosan D34 diesel engines manufactured between 2014 and 2020. These engines are commonly found in skid-steer loaders, compact track loaders, construction equipment, and other off-highway machinery that rely on advanced aftertreatment systems to maintain efficient emissions control.
Installation Notes
Before installing the replacement DOC, allow the exhaust system to cool completely. Inspect the exhaust piping, clamps, mounting hardware, temperature sensors, and surrounding aftertreatment components for wear, contamination, or damage. Install the new catalyst using the correct seals and hardware to ensure proper alignment and a leak-free fit. After installation, verify that all sensor connections are secure, inspect for exhaust leaks, and confirm proper operation of the aftertreatment system before returning the equipment to service.
Final Thoughts
The Diesel Oxidation Catalyst is a critical component of the emissions system, helping prepare exhaust gases for downstream filtration and treatment. The Bobcat / Doosan D34 DOC (OEM 7313995) delivers reliable exhaust emissions control, dependable compatibility with factory aftertreatment components, and long-lasting service for 2014–2020 Bobcat and Doosan D34-powered equipment.
