3850618 Splined socket (small) | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta splined socket, published at 0.408 kg. Volvo's own special tools listing records it as a small splined socket in the overhaul class and gives it a named job: holding the fixture, working with 3862847. Our listing has carried it as a socket wrench, and no drive or across-flats size is published. Splined socket 884830 at 0.127 kg carries the same designation but is listed for turning the vertical shaft, so the two are different tools with the same name. The other socket wrench in our range, 3850598, weighs 0.229 kg.
