McLaren Accumulator Spanner Wrench
This McLaren accumulator spanner wrench safely removes and installs hydraulic accumulators on McLaren 720S, 750S, and 765LT models.
It engages the mounting holes on the accumulator housing, allowing proper leverage without damaging the component.
In 2021, McLaren introduced an updated accumulator design used on 720S, and on all 750S, and 765LT models. This tool is built specifically for that newer style.
Additionally, using the correct tool prevents damage and makes removal much easier compared to improvised methods.

Accumulators shown in images are for demonstration only and are not included.
