181302 Cup | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta cup is a precision rolling-element or raceway component used in the TAD11 lower-gear and legacy AQ145A tapered-bearing assembly. 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 provides the hardened outer raceway for the matching tapered roller bearing cone/inner-ring assembly. Selection must be confirmed by OEM part number 181302, the exact engine/product model, serial number and installed configuration.

🚤 Compatibility

• Engine Family: MD, TMD, AQ, AD, AQAD, D, BB, TAMD, MS, DP, SP, DPX, TAD, AQD

🔌 Function

Provides the hardened outer raceway for the matching tapered roller bearing cone/inner-ring assembly. 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

• Rumbling or grinding from the bearing housing
• Pitting, scoring or flaking of the race surface
• Blue or brown heat discolouration
• Notchy or rough feel when the shaft is turned
• Metallic particles in the lubricant

🛠️ Service Notes

• Renew the cup and its matching cone or roller assembly together as a set; a new roller set run in a used cup will not last
• Clean the housing bore and check it for wear, scoring and corrosion, and remove any burr so the cup can seat properly
• Drive or press the cup in square, bearing only on its back face with a tool that matches its diameter, until it is hard against its shoulder — a cup that is not fully home throws the whole bearing setting out
• Never strike a bearing race directly with a steel hammer and never press through the rollers
• Lubricate with the specified oil or grease and set the bearing preload or end float by the method and figures given in the workshop manual for your unit
