Spierings Mobile cranes, SK

Manual transmission fluid capacity & service interval

Spierings Mobile cranes, SK manual transmission fluid capacity ranges from 8 to 13 liters. The data covers 5 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Type	Specifications
SK345-AT3, DAF DHS 825L	Use: Normal Capacity 13 liter Code: ZF S6-90 6/1
SK365-AT3, DAF RS 222L (Euro 1)	Use: Normal Capacity 8 liter Code: ZF 9S-109 9/1
SK377-AT3, DAF PE 265C (Euro 3)	Use: Normal Capacity 11 liter Code: ZF Ecosplit 16S151 16/2
SK477-AT4, DAF WS 268L (Euro 3)	Use: Normal Capacity 11 liter Code: ZF Ecosplit 16S151 16/2
SK488-AT4, DAF XE 280C (Euro 3)	Use: Normal Capacity 11 liter Code: ZF Ecosplit 16S151 16/2

The Spierings SK345-AT3 paired with the DAF DHS 825L engine carries the largest manual transmission fluid capacity in the SK series listed here, at 13 liters. A higher transmission fluid volume generally reflects a larger or more complex gearbox assembly.
The SK365-AT3 with the DAF RS 222L (Euro 1) engine has the smallest manual transmission fluid capacity across all listed configurations, at 8 liters. Euro 1 emission classification indicates an older engine standard, predating the tighter Euro 3 requirements seen in later SK models.
The SK377-AT3, SK477-AT4, and SK488-AT4 configurations all share an 11-liter manual transmission fluid capacity, despite pairing with three different DAF engine variants: the PE 265C, WS 268L, and XE 280C respectively.
All five configurations carry a normal use condition designation, meaning the 13-liter, 8-liter, and 11-liter capacities listed apply under standard operating conditions rather than severe-duty cycles.
The AT3 and AT4 designations in the model names indicate different crane series within the SK range. Both the AT3 and AT4 series include configurations with an 11-liter manual transmission fluid capacity, as seen in the SK377-AT3 and the SK477-AT4 and SK488-AT4 pairings.
The two Euro 3 engine variants paired with AT4 cranes, the DAF WS 268L and DAF XE 280C, share identical 11-liter manual transmission fluid capacities, suggesting the gearbox used across these configurations holds the same fluid volume regardless of engine variant.
