183704 Roller Bearing | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta roller bearing is a precision rolling-element or raceway component used in the clutch and power-take-off roller-bearing position. 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 clutch/PTO shaft and maintains alignment under transmitted engine torque. Selection must be confirmed by OEM part number 183704, the exact engine/product model, serial number and installed configuration.

🔌 Function

Supports the clutch/PTO shaft and maintains alignment under transmitted engine torque. 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

• Low-frequency rumbling or growling under load
• Spalling, flaking or deep pitting on the raceways
• Heat discolouration of rollers or races
• Shaft play, run-out or heavy vibration
• Substantial metal debris in the oil

🛠️ Service Notes

• Keep the bearing in its wrapper until the moment of fitting and work with clean hands and clean tools — a roller bearing is ruined by grit long before it is ruined by use
• Apply the fitting force only to the race being fitted, using a tube or drift that bears squarely on the whole ring face, so the load never passes through the rollers; never strike the bearing or press on the loose race
• Warming the inner race evenly in oil or a purpose-made bearing heater lets an interference fit slide on without hammering — never heat a bearing with a flame, and stay within the temperature the manufacturer's instructions allow
• Check the shaft and housing seats for wear, scoring and burrs first; a slack or damaged seat will destroy a new bearing quickly
• Lubricate with the grade specified for that position, and where the bearing takes an adjustable preload or endfloat — tapered roller bearings especially — set it by the workshop manual procedure rather than by feel
