181268 Needle Roller Assembly | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta needle roller assembly is a precision rolling-element or raceway component used in the upper vertical-shaft and reverse-gear needle-bearing positions. It is manufactured to the original Volvo dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it supports the selected vertical or transmission shaft using compact needle rollers where radial space is limited. Selection must be confirmed by OEM part number 181268, the exact engine/product model, serial number and installed configuration.

⚙️ Key Features

🔌 Function

Supports the selected vertical or transmission shaft using compact needle rollers where radial space is limited. Measure shaft and housing fits, renew contaminated lubricant and related seals, and install using force only through the race being fitted. Set preload or end float to the applicable Volvo Penta specification.

⚠️ Common Signs of Failure

• Whining or rumbling that changes with shaft speed
• Scoring or brinelling marks on the shaft the needles run against
• Rollers loose in, or escaping from, the cage
• Increased shaft play or vibration
• Fine steel debris in the oil

🛠️ Service Notes

• Keep everything clean and work with clean dry hands and tools; needle bearings are intolerant of both grit and moisture
• Never press on the rollers or the cage — press only on the end face of the outer shell, using a drift or tube that matches its diameter so the load passes straight through
• Where the shell has a marked or lettered face, that face takes the drift; press the bearing in square and to the depth the manual gives
• Check the housing bore and the shaft or journal for wear, scoring and corrosion before fitting, because a new needle bearing on a worn shaft will not last
• Prime or pack the bearing with the specified lubricant before assembly and renew the adjacent seals so the new bearing stays clean
