9996398 Manometer | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta 9996398, weighing 0.510 kg. Volvo Penta's own special tools catalogue designates it a manometer and lists 254 products against it: the D3, D8, D9, D11 and D13 engines, IPS and the TAD, TWD and TWG ranges. It supersedes 9995270, which the same catalogue shows as a pressure gauge listed for the D3 range, and nipples 9996591 and 9996666 supersede that number as well, so an order against 9995270 alone will not bring everything the test set needs.

⚙️ Key Features

• Designated a manometer in Volvo Penta's special tools catalogue
• 0.510 kg
• Listed for the D3, D8, D9, D11 and D13 engines, IPS and the TAD, TWD and TWG ranges
• Supersedes 9995270, which is also superseded by nipples 9996591 and 9996666

🔌 Function

Reads the pressure in the circuit under test so the measured figure can be compared against the workshop specification.

⚠️ Common Signs of Failure

• Needle no longer returning to zero at rest
• Reading drifting or hunting instead of settling
• Glass cracked, or fluid weeping from the case
• Connection thread damaged, so it will not seal to the test point
• Readings that disagree with a known-good instrument on the same test point

🛠️ Service Notes

• The old 9995270 maps onto this manometer plus nipples 9996591 and 9996666, so check which of them your set-up needs before ordering
• Zero the instrument and check it against a second one before condemning an engine on one reading
• Depressurise the circuit before disconnecting
