IMPORTANT:
STANDARD SIZE exhaust valve for John Deere 6076 (7.6L) and 6081 (8.1L) diesel engines. Requires 6 exhaust valves per engine (2-valve-per-cylinder design). The 6076 and 6081 share the same valve — the 6081 is a destroked/bored version of the same block. Do NOT order standard valves if your head has been machined for .015" oversize stems — use R93313 (oversize exhaust) instead. Also do NOT confuse with intake valve for these engines — exhaust valves have smaller head diameter.
Fits 8100/8200/8300/8400 tractors (6076), 8110/8210/8310/8410 (6081), and 9500/9600/9610 combines. When replacing, inspect valve guides for wear — if guides are worn beyond spec, they must be replaced or reamed for .015" oversize valves. Replace valve stem seals and check spring free length. Measure valve protrusion after seating. On high-hour 6076/6081 engines, check exhaust valve seats for recession — excessive recession requires seat replacement or insert installation.
⚠️ Standard size — for .015" oversize stems, order R93313 instead.
