3841055 Adjusting Washer | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta adjusting washer 1.95 mm thick, listed for 11 applications on D and DPI series engines and drives. Thickness is the whole point of this part: it sits in a graduated set with 3841056 at 2.00 mm, 3841057 at 2.10 mm and 3841058 at 2.15 mm, and the published weights do not follow thickness at all, so order strictly by the measured shim size.

🔌 Function

Sets a running clearance or preload by taking up a measured amount of axial space in the assembly.

⚠️ Common Signs of Failure

• Backlash or preload measuring outside specification on assembly
• Whine, growl or rumble from the assembly under load
• Washer visibly worn, dished, scored or bedded in
• Bearing marks showing the components were running out of position

🛠️ Service Notes

• Measure the existing shim and the actual clearance before choosing a size, as the four thicknesses are only 0.05 to 0.20 mm apart
• Check adjacent washers 3841056, 3841057 and 3841058 if your measurement calls for a different thickness
• Do not stack shims to make up a size unless the workshop procedure allows it
