IMPORTANT:
This is a SEMI-FINISHED universal bore cylinder liner (106mm bore) — it MUST be bored and honed to final size after installation. Do NOT install and run without machining. Universal liners are designed as repair/service sleeves for engines that originally came with parent bores (no factory liners). The block must be bored oversize to accept the sleeve. Compatible engines include John Deere 4045/6068 PowerTech (4.5L/6.8L). Found in John Deere 6400/6410/6420 tractors, 310E/310G backhoe loaders, and other 4045/6068-powered equipment. For OEM JD finished liners, see R116383 (standard), R116397 (hardened), or R80500 (older 4276). The 4045 (4-cyl) and 6068 (6-cyl) share the same 106mm bore and liner. Consult the engine service manual for parent bore machining specifications and interference fit requirements.
⚠️ Semi-finished universal liner — requires boring and honing after fitting.
