# 994077 Stud | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta stud 175 mm long, weighing 0.086 kg and listed for 17 applications across the D and TAD engine series. Important: the old part number 21269432 is replaced by TWO current studs - this one and 994078 - so if your paperwork calls for 21269432, ordering this number alone may leave you short. Check which of the two your job needs, or whether it needs both.

## 🔌 Function

Screws permanently into the casting to give a long fixed threaded spigot, letting the component be located and clamped with a nut without cutting the parent thread each time.

## ⚠️ Common Signs of Failure

-   Nut will not hold torque, or winds the stud out instead of tightening
-   Stud comes away with the nut on dismantling
-   Thread stripped, stretched or corroded
-   Stud bent or snapped off level with the casting face

## 🛠️ Service Notes

-   If your list calls for 21269432, check both 994077 and 994078 before ordering - one old number now covers two current studs
-   Measure the length: this is the 175 mm stud
-   Inspect the tapped hole in the casting before fitting, as a pulled parent thread will not be cured by a new stud
