# 1556434 Stud | Genuine Volvo Penta Part

## 🔧 Product Description

This genuine Volvo Penta stud is a structural fastening, locking or support component used in the piston-cooling jet mounting. It is manufactured to the original Volvo Penta dimensions and interface requirements so the assembly retains its designed clamp load, support and alignment. Maintains the revised OEM service configuration. In service, it secures piston-cooling jet 1556430 in the cylinder block at the correct angle. Fitment is controlled by the exact engine or product configuration and serialised parts list; confirm OEM number 1556434 against the installed assembly before ordering.

## 🚤 Compatibility

-   **Engine Family:** TWD, TID, TD, TAMD, TAD
-   **Serial Range:** SNXXXXXXXXXX/12629-

## 🔌 Function

A stud provides a fixed threaded anchor point that allows a component to be located and then clamped down by a nut. It maintains consistent clamping force at the joint and simplifies repeated removal and refitting of the mating part.

## ⚠️ Common Signs of Failure

-   Stripped, damaged or corroded threads preventing correct nut torque
-   Stud stretched or necked from over-torquing, causing loss of clamping load
-   Fastener loosening in service, with joint leakage or vibration at the mounting face
-   Snapped or seized stud discovered during component removal
-   Visible corrosion pitting or thread galling on the exposed section

## 🛠️ Service Notes

-   Clean and chase the female thread before fitting so the stud can pull down square and to full depth
-   Screw studs in with a proper stud installer or the double-nut method; gripping the plain shank with pliers or self-grips scores it and the nut will never seat or torque correctly afterwards
-   Screw the stud home until it seats as the manual for your engine describes, and no further — a stud wound in hard to cure a slack thread will simply split the casting
-   Renew studs that are stretched, necked, bent or corroded rather than reusing them; exhaust and manifold studs in particular are cheap next to the work of extracting a broken one
-   Tighten the nuts to the torque figures and in the sequence given in the workshop manual for your engine, and where a stud passes into an oil or coolant space seal it as the manual specifies
