Application:
Exhaust Valve Guide 3343J021 is a precision-machined, straight-type guide that services the exhaust valves of Perkins 4.236, 4.248, 1004-4, 1004-40T, 1006-6, T6.354 and 1104C-44/1104D-44 diesels. Typical host machines are Massey Ferguson MF240, MF260, MF270, MF5425, MF5435 tractors, JCB 3CX/4CX back-hoe loaders, Manitou MLT tele-handlers, Claas combine harvesters, Landini Legend and Atlantis ranges plus 60–200 kVA generator sets. Because the 9.52 mm bore, 15.92 mm OD and 61 mm length are dimensionally identical to earlier 4.236 units, the same 3343J021 guide is used as a single service solution across forty years of 4- and 6-cylinder Perkins production.
Technical specifications:
Overall length 61 mm, outside diameter 15.92 mm, valve-stem bore 9.52 mm, seat-counter-bore 11 mm, wall thickness 3.2 mm, designed guide-to-stem clearance 0.04–0.07 mm at 90 °C operating temperature.
Material & performance features:
Produced from centrifugally-cast low-alloy grey cast iron (Hardness 200–240 HB), the matrix contains 0.6 % free graphite that acts as a built-in lubricant, lowering the coefficient of friction against the chrome-plated valve stem by 25 % compared with plain grey iron. After finish-boring, the bore is diamond-honed to Rz ≤ 1.6 µm surface roughness, eliminating break-in time and cutting initial wear by 30 %.
