Exhaust Valve Compatible With 2003-2012 Jcb 8040Z/8045Z/8050Z/8052 804C/D 3.3L 4-Cyl Diesel Mp10423

JCB EQUIPMENT:
• JCB 8040Z/8045Z/8050Z/8052/8055/8060 804C 3.3L Diesel (2003-2012)


IMPORTANT:
EXHAUST valve for Perkins 804C and 804D engines (3.3L, 4-cylinder, turbocharged, direct injection). The Perkins 804C/D is a compact diesel used primarily in JCB mini excavators and compact equipment. Do NOT confuse with the larger Perkins 1104C/1104D (4.4L) — the 804C/D is a different, smaller engine family with different valve dimensions. Also do NOT confuse with Cummins B3.3/QSB3.3 exhaust valves — despite the same displacement, these are different engine designs with non-interchangeable valves. Requires 4 exhaust valves per engine. Do NOT confuse with intake valve MP10426.

Fits JCB 8040Z/8045Z/8050Z/8052/8055/8060 mini excavators and similar JCB compact equipment. When replacing, inspect valve guides for wear and valve seats for pitting or erosion. Replace valve stem seals. Exhaust valves see the highest thermal stress — check removed valves for heat cracking, face erosion, and tulip deformation. Check spring free length and adjust valve lash per Perkins service manual after reassembly.

⚠️ Exhaust only — for intake, order MP10426. Confirm engine is 804C/D (not 1104).
