3584402 Countershaft | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta countershaft for the 2.01:1 ratio, from the Marine Propulsion group. It weighs 7.882 kg and is listed for 20 applications across the D and HS series. A second 2.01:1 countershaft, 3584403, weighs 15.006 kg, so the ratio alone will not separate the two.

🛠️ Service Notes

• Both 2.01:1 countershafts are listed for the same 20 applications, so weight is the only thing that separates them - 7.882 kg here against 15.006 kg for 3584403
• Weigh or measure the shaft you are replacing, or take the number off the unit
• Renew the bearings and set the shim pack to specification when the shaft goes back
