# 23726379 Transfer Case | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta transfer case with a 1.09:1 ratio, weighing 43.54 kg and listed for five applications. The ratio is critical, and note the 1.00:1 case is more than twice the weight - so these are structurally different units, not just different gearing.

## 🚤 Compatibility

Typically suits:

-   Volvo Penta 557
-   Volvo Penta 627
-   Volvo Penta 527
-   Volvo Penta 577S
-   Volvo Penta 627SV

## ⚙️ Key Features

-   Transfer case with a 1.09:1 ratio
-   43.545 kg
-   Listed for five applications
-   The 1.00:1 case 23726380 weighs 104.78 kg, so the two are structurally different units rather than the same case geared differently

## 🔌 Function

Takes the drive from the engine and passes it on at a 1.09:1 ratio, setting the shaft speed the propulsion unit sees.

## ⚠️ Common Signs of Failure

-   Whine or gear noise that rises and falls with engine speed
-   Oil leaking from the case joint or the shaft seals
-   Vibration through the drive line under load
-   Metal glitter in the oil or on the drain plug magnet
-   Chipped gear teeth and worn bearings found on strip-down

## 🛠️ Service Notes

-   Confirm the ratio before ordering - the 1.00:1 case is 23726380 and is not an alternative to this one
-   At over 40 kg this needs mechanical lifting and proper support while it is unbolted

## 📦 Condition

-   Genuine Volvo Penta part
