## 🔧 Product Description

Genuine Volvo Penta spider (part number 1209814), a coupling element used within the drive/coupling assembly on THD102 series and DH10A diesel engines. The spider sits between the driving and driven halves of a jaw-type coupling, transmitting torque while absorbing shock and minor misalignment. Supplied as an individual replacement item with a net weight of 0.8 kg.

## ⚙️ Key Features

-   OEM Volvo Penta part number 1209814
-   Net weight 0.8 kg
-   Coupling spider element for jaw-type drive couplings
-   Fits THD102 series and DH10A diesel engines
-   Supplied as a single replacement component

## 🔌 Function

The spider is the intermediate element in a jaw-type coupling, transferring torque between the two coupling halves. It also cushions torsional shock and tolerates small amounts of shaft misalignment to protect connected components.

## ⚠️ Common Signs of Failure

-   Increased vibration or knocking noise from the coupling during operation
-   Visible cracking, crumbling or chunking of the spider element
-   Excessive rotational free play or backlash between the coupling halves
-   Debris or worn material found around the coupling housing
-   Loss of drive or intermittent torque transfer under load

## 🛠️ Service Notes

-   This is the rubber insert for a jaw-type flexible coupling on THD102 / DH10A engines - it has no needle bearings, trunnions or seals to renew, unlike the U-joint cross spiders listed elsewhere under this same item type
-   Check the coupling halves' jaw condition where the spider seats before fitting a new one, since worn jaws wear a replacement insert the same way
