Frequently Asked Questions

What JCB 3CX engine parts does Broken Tractor carry?

Broken Tractor carries a range of JCB 3CX engine parts, including a DieselMax crankshaft, connecting rod, rear upper main bearing, thrust washer kits and a +0.50mm oversized piston ring kit. We also offer external components for the 3CX such as the crankshaft pulley, lower belt idler pulley, rubber engine mount, oil pressure switch, baffle plate and a 32mm magnetic drain plug. Fitment can vary by engine and serial number, so match the part number from your old part before ordering.

Which engine is used in JCB backhoes?

Many JCB 2CX and 3CX backhoes, along with the 3DX Super and 3DX Xtra, use the JCB DieselMax engine, and many internal parts are shared across that engine family. Older machines such as the 1400B, 1550B, 1600B, 1700, 214, 215, 216 and 217 use earlier engines with their own crankshaft and bearing parts. Because engine fitment depends on the model and serial number, confirm your engine before ordering internal parts.

What are the names of the main JCB backhoe engine parts?

The main internal JCB engine parts include the crankshaft, connecting rods, pistons and piston rings, main bearings, thrust washers and push rods, all sealed by gasket sets like an upper engine gasket kit. External engine parts include the oil pan (sump), drain plug, crankshaft pulley, belt idler pulley, engine mounts, oil pressure switch, fuel leak-off rail pipe and starter motor. Broken Tractor offers parts in each of these groups for JCB 2CX, 3CX, 4CX and legacy backhoes.

Do JCB engine bearings and piston rings come in oversize and undersize sizes?

Yes, Broken Tractor offers JCB bearing and piston ring kits in sizes other than standard. Examples include a +0.50mm oversized piston ring kit for 2CX, 2CXL, 2CXS, 3CX, 3DX Super and 3DX Xtra engines, and a main bearing kit for a 0.25 undersize crankshaft for the 2CX, 2CXL and 2CXS. The right size depends on whether your block or crankshaft has been machined, so check measurements or markings before ordering.

Which JCB backhoe models do these engine parts fit?

Broken Tractor carries engine parts for the JCB 2CX series, 3CX series including the 3CX Compact, 3DX Super and 3DX Xtra, the 4CX, 4CN and 4CX Wastemaster, the 5CX, and legacy 1400B through 217 machines. Each part fits a specific set of models, for example the rubber engine mount fits the 3CX, 4CX, 4CN and 5CX while the engine oil pan fits the 2CX family. Since fitment can change by serial number, match your part number or call (800) 909-7060 to confirm with the parts team.
