3801994 Servo Unit Reman | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured steering unit servo, listed in the reman catalogue as the SUS for the IPS 10 drive on the 1.84:1 ratio, weighing 8.07 kg and covering 34 applications across the D and IPS series. It supersedes part number 3801961, which carried the same description. The rest of that drive is upper gear 3801875, lower gear 3801678 and complete drive 3801874. This unit is supplied on an exchange basis: core deposit 3804994 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
