3803944 Injector | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured injector weighing 0.193 kg, listed for the D5A-T and D7A-T. The reman catalogue puts it against the D5A T-A, D7A T-A and their generator-set versions outright, and against the D5A TA-A from serial number 991715 onwards and the D7A TA-A from serial number 977118 onwards. Below those serials the aftercooled engines take 3803945 instead, so the serial number is the deciding detail on a TA-A engine. Injector 3803236 for the KAD42A and KAMD42A shares this exact published weight, so the scales are no help. Supplied on an exchange basis: core deposit 3806944 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
