# 1529230 Nut Set | Genuine Volvo Penta Part

## 🔧 Product Description

A genuine Volvo Penta nut set used in SAE No. 2 flywheel-housing installations equipped with Allison MT643 or MT653 automatic transmissions. The set secures the drive-coupling or flywheel-related connection in the specified transmission installation. The Volvo nut set is cross-referenced with Allison number ALL23014462. Associated washers such as 960142 can appear in the same arrangement but are separately serviced unless explicitly included with the supplied set.

## 🔌 Function

The nuts clamp and retain mated engine components at their fastening points, holding the joint under the correct load. Supplying them as a set allows all fasteners at the location to be renewed together during reassembly.

## ⚠️ Common Signs of Failure

-   Thread damage, galling or seizing that prevents correct tightening
-   Rounded or deformed flats that no longer accept a socket or spanner
-   Loss of clamping load with fasteners backing off in service
-   Corrosion or heat discolouration making removal difficult
-   Leaks, vibration or component movement at the fastened joint

## 🛠️ Service Notes

-   This set secures the SAE No. 2 flywheel-housing to an Allison MT643 or MT653 automatic transmission on the TWD740VE - a driveline fastener set, not the alternator or charging-terminal nuts listed elsewhere under this item type
-   Cross-referenced to Allison part ALL23014462 - useful when working from Allison's own parts documentation rather than the Volvo Penta catalogue
