980835 Stud | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta stud 155 mm long for the later version of the expansion tank, weighing 0.095 kg and listed for 18 applications across the TAMD, AD, D, TMD and KAMD series. Both the length and the later tank version matter - fitting it to the earlier tank arrangement will not give the right projection.

🔌 Function

Provides a long threaded pillar for mounting the expansion tank, so the tank can be fitted and removed on nuts without wearing the thread in the casting.

⚠️ Common Signs of Failure

• Expansion tank loose on its mounting or moving with engine vibration
• Stud winding out with the nut on dismantling
• Thread corroded or stripped at the exposed end
• Stud bent where the tank has been forced into place
• Mounting losing torque and needing repeated retightening

🛠️ Service Notes

• Confirm which version of the expansion tank is fitted before ordering - this stud is for the later arrangement
• Check the tapped hole is clean and set the stud to the specified projection so the nut has full engagement
