Volvo Penta TAMD61A-TAMD72WJ-A Marine Diesel Engine Workshop Manual (Ref. No. 7735718-4, August 1996)

Documenting the 1996 Volvo Penta TAMD61A through TAMD72WJ-A marine diesel series, this official OEM publication (Ref. No. 7735718-4, published August 1996) serves as the primary technical reference for the 6(x) and 7(x) engine lineup. Spanning 91 pages, it delivers precise assembly data focusing on the engine body, cylinder head, crankshaft, and fuel system specifications. The document includes detailed exploded-view diagrams, comprehensive torque tables, and exact clearance charts for internal components to support accurate workshop overhauls.

Engine Body and Assembly Documentation

This manual details critical engine body maintenance and overhaul reference data for heavy-duty marine powerplants. Technicians will find specific technical parameters on cylinder head renovation, including maximum warpage tolerances, milling dimensions for seal grooves, and exact valve seat replacement criteria. The documentation heavily focuses on crankshaft assembly, outlining specifications for main bearing replacement and the correct tightening sequences for cylinder head screws. Furthermore, it outlines piston and connecting rod removal alongside cylinder liner inspection and honing criteria. It also details the timing gear configuration across the various 6-cylinder variants. Please note that handling commercial marine diesels and components like fluorocarbon rubber seals requires strict adherence to standard workshop safety protocols and environmental regulations to prevent severe injury or material contamination.

Specifications and Reference Values

Accurate technical data is the foundation of a reliable engine rebuild. The publication documents exact bore, stroke, and displacement measurements for the entire covered engine range. Mechanics can verify piston ring gap tolerances specifically for the 1996 TAMD61A series using the included inspection tables. Torque application is critical; therefore, the text provides exact cylinder head bolt tightening values, specifying 85 Nm for the 6(x) series and 90 Nm for the 7(x) series. For valve train calibration on the TAMD71 series, the inlet valve clearance is listed at exactly 0.40 mm. Additionally, the manual features essential dimensional data for camshaft measurement and wear limits. This resource functions strictly as an authoritative data and specification guide for these marine applications, providing component parameters rather than step-by-step diagnostic tutorials.
