Crom® Head Gasket Set for Volvo Penta AD31 TAMD31 TMD31 KAD32 3582435 3582432

This head gasket kit, also known as a decarbonizing gasket kit, includes the head gasket with reference  3582432, 858993, 838628. The cylinder head bolts with reference 838775 should be replaced when needed[1], and tightening should be performed in five stages, following the attached diagram. 

Tightening torque settings:

• 30 Nm
• 60 Nm
• 100 Nm
• Angle-tighten the screws 90° in numerical order as follows: Mark up the position of the screw heads with a chalk mark on the screw and cylinder head. Do not use a punch or a scribe as they can confuse future operations. Mark a 14mm socket, locate the socket as illustrated on the second picture, with the socket marking 90°counter-clockwise from the chalk mark on the cylinder head. Carry out angle tightening by tightening until the socket mark and the cylinder head chalk-mark are opposite each other.
• Angle-tighten the screws 90° in numerical order as above. Tightening is finished when all screws have been angle tightened to 90°. Retightening after use is not necessary.

Kindly check the second picture that provides the necessary instructions, directly quoted from the Volvo Penta workshop manual.

[1] The cylinder head bolts should be replaced when there are signs of elongation, or cannot be specified if it is already elongated, by checking the "waist" of the bolt.
