Description
Overview:
This drive belt is a non-genuine replacement for OEM 331/38446, made for reliable use on JCB backhoe loaders such as the 3CX and 3CX-2. Built from durable, heat- and oil-resistant rubber with a reinforced cord layer, it delivers steady grip and long service life in tough site conditions. The belt transfers engine power to ancillaries, typically the alternator, water pump and cooling fan, helping to maintain charging and cooling performance under load. It is suitable for routine servicing or repair work and is designed to fit correctly when installed and tensioned to specification. A practical choice for tradespeople, plant hire, and DIY users who need dependable power transmission without excessive downtime.
Key Features:
- Non-genuine replacement that matches the fit and function of OEM 331/38446
- Heavy-duty rubber compound with reinforced cords for strength and long flex life
- Stable tension and positive grip to reduce slip, glazing and premature wear
- Resistant to heat, oil splashes, dust and abrasion commonly found on worksites
- Accurate profile for smooth, efficient power transfer to engine ancillaries
- Easy to fit with basic tools; suitable for standard belt tensioning methods
- Supports planned maintenance to minimise breakdowns and protect components
- Suitable for JCB backhoe loaders in the 3CX/4CX family
Typical Applications:
Used to drive engine accessories on JCB diggers in everyday site work, plant hire fleets and owner-operated machines. Typical duties include maintaining alternator output, coolant circulation and fan operation during earthmoving, loading and roading. Ideal for preventative maintenance or like-for-like replacement when the original belt shows cracking, glazing, noise, or loss of tension.
