The JCB 427 wheel loader’s articulation joint has a heavy-duty box section, a heavy-duty center pin and an oversized bushing, as well as twin taper roller bearings on the bottom box joints. This setup can easily tolerate vertical and horizontal loads.
Finite element analysis, as well as extensive endurance and rig testing ensure superior structural strength and durability. Cold cell testing guarantees starting performance down to -20°C.
High tolerances and accurate location of pins and bushings are assured with JCB’s precision machining techniques. State-of-the-art manufacturing processes like robot machining, precision paint technology and innovative assembly techniques help to achieve the very highest levels of build quality.
A solid cast rear counterweight protects the rear of your JCB 427 wheel loader – including the rear lights and cooling pack – from damage. Hoses are neatly routed and clamped through the articulation joint, well away from any pinch points.
The new front chassis is more durable than ever; it's been strengthened with additional ribs and gussets for maximum service life. For additional protection, there are impact-resistant fender edges and trims fitted.
This wheel loader has integral steel fluid tanks for the ultimate in leak protection: a far superior solution to the plastic tanks favored by some competitors.
