Information
Four point gearbox bearing.
A four-point contact bearing inside the gearbox housing that supports the pinion / differential or output shaft, maintaining correct alignment and rotational support under load. It is a critical structural component of the transmission case on classic 911 / 914 gearboxes. Sold as a single bearing unit - replace as needed when rebuilding or servicing the gearbox, or when diagnosing shaft play or bearing wear.
Fits:
Porsche 911 1965 - 1971 Manual Gearbox cars
Porsche 911 1965 - 1983 Sportomatic Gearbox cars
Porsche 914 1970 - 1976 Manual and Sportomatic gearboxes
This bearing replaces the factory-installed unit (or previous equivalent bearing - OE part number 99905201600) and restores proper gearbox support for shafts that transmit torque and rotational forces - vital for gearbox longevity and reliable shifting.
Gearbox bearings wear out over time from torque loads, heat, and repeated cycles. A worn or damaged four-point bearing may lead to:
• Shaft misalignment or excessive play
• Increased gear noise, whining or rumbling
• Premature wear on shafts, gears, or synchros
• Gearbox instability or failure under load
Replacing with a correctly spec’d bearing restores shaft integrity, ensures smooth power transmission, and helps prevent costly internal damage - especially important on vintage 911 and 914 gearboxes where early detection can save major rebuilds.
You should consider replacing this bearing if:
• There is noticeable shaft play or wobble in the gearbox output or pinion shaft
• You hear whining, rumbling, or unusual noise from the gearbox under load
• The gearbox has high mileage or has seen hard use
• You are performing a gearbox rebuild, overhaul, or restoration
• Internal inspection reveals bearing wear, scoring, or heat damage

Information
Needle roller bearing.
This needle roller bearing, also known as a needle cage bearing, is used in the Porsche 915 type manual transmission. In the gearbox, needle roller bearings support and permit rotation of internal components by minimizing friction between moving parts.
Fits:
Porsche 911 1974 - 1986 4 & 5 speed
Diagram Ref no 7.
This OE Match version meets original specification dimensions and tolerances to ensure proper fit and function when replacing worn or damaged bearings.
The needle roller bearing provides smooth rotational support for transmission shafts and gears. It helps reduce friction and wear between the main shaft and the transmission housing or gear assemblies, allowing gearsets to spin freely and reliably under load. This results in consistent gear engagement, reduced drivetrain stress, and a smoother shifting experience.
Function
• Friction Reduction: Needle rollers reduce surface contact friction between rotating components.
• Load Handling: Supports radial loads within the transmission at critical gear positions.
• Smooth Operation: Promotes precise and efficient gear movement with minimal resistance.
• Long Service Life: Engineered to resist wear and maintain structural integrity under continued transmission stresses.
Over time, the original needle roller bearings can become worn, leading to increased friction, gear noise, and premature wear of transmission components. A failing bearing may cause rough shifting, gear chatter, or accelerated gearbox wear. Replacing the worn bearing with an OE Match part ensures proper internal support, restores smooth gearbox operation, and helps protect more expensive transmission components from damage.
Replace this bearing if you notice:
• Unusual gearbox noise, especially when changing gears
• Rough or notchy shifting feel
• Vibration or unusual resonance from the transmission
• Sluggish gear engagement
• During full gearbox rebuild or overhaul

• Function: This bearing supports and aligns the differential carrier or manual transmission rear output shaft, allowing smooth rotation under load and controlling radial/axial movement of the carrier assembly. It ensures the differential or transmission output runs true, quietly and with minimal friction.
• Position on Car: Usually located in the manual transmission/differential rear housing (for example in the rear of the 911 manual gearbox, or the transaxle/differential carrier area). It may serve as the bearing between the carrier housing and the output shaft or differential ring-gear carrier.
• This part is critical for proper gear meshing, quiet running, bearing life and overall driveline integrity.
With age and use, the bearing can develop wear in its rollers/races, looseness, noise, increased friction, or misalignment. A worn bearing may lead to drivetrain noise, vibration, premature gear or bearing damage, loss of efficiency, or catastrophic failure. The bearing supports the differential carrier output shaft – incorrect bearing performance can result in excessive play, wobble, and stress on neighbouring components.
When to Replace:
• During a differential or transmission rebuild, where the carrier, output shafts or bearings are being replaced — it’s best practice to install new bearings.
• If you detect noise (growl, whine, hum) coming from the rear differential or output area, particularly under load or at higher speed. If there is measurable play / movement in the differential carrier or abnormal backlash in the gearset. If you notice metal debris, “bearing-noise” or vibration emanating from the drivetrain output / differential area.

About Bearings / Bearing Retaining Plates / Bushes
OEMatch Bearings / Bearing Retaining Plates / Bushes — Fit, Function, Confidence
OEMatch supplies bearings, retaining plates and bushes for Porsche models, intended to support gearbox rebuilds, maintenance and restoration projects. These precision parts maintain shaft alignment, reduce friction and control vibration to preserve gearbox behaviour across road and competition applications. OEMatch catalogs over 4,000 individual part numbers and more than 8,700 OE cross-references, and continues to develop new lines for Porsche applications.
Available Types
- Individual gearbox bearings for input, layshaft and output shafts
- Machined and pressed bearing retaining plates and covers
- Polymer and metal bushings supplied as single items or repair kits
Understanding OEMatch Bearings / Bearing Retaining Plates / Bushes
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original bearings, retaining plates and bushes.
OE (Original Equipment) refers to parts matching original specifications for the bearings, retaining plates and bushes and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM bearings, retaining plates and bushes engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Bearings, retaining plates and bushes support rotating assemblies and keep gearsets correctly aligned. Bearings reduce friction between moving parts, retaining plates fix bearing position and resist axial movement, and bushes absorb side loads and damp vibration. Correct material, heat treatment and machining tolerances are key for reliable service life in Porsche gearboxes.
Benefits Include
- Restored gear alignment and smoother gear engagement
- Reduced friction and lower operating temperatures
- Less vibration and quieter gearbox operation
Why Bearings / Bearing Retaining Plates / Bushes Wear and Fail
- Insufficient or contaminated lubrication leading to accelerated bearing wear
- Heat damage and material fatigue from sustained high loads
- Corrosion and contamination from moisture or debris ingress
The Importance of Replacing with OEMatch Bearings / Bearing Retaining Plates / Bushes
Replacing worn bearings, retaining plates and bushes restores precise shaft support and prevents secondary damage to gears and shafts. Using well-specified replacements reduces the risk of noise, shifting issues and rapid re-wear after a rebuild. For Porsche gearboxes, matching materials and tolerances helps maintain intended clearances and load distribution, which is especially important where high revs and sustained torque are encountered.
Advantages
- Parts selected for Porsche applications and cross-referenced to common original numbers
- Options for standard replacement or upgraded materials where listed
- Kits and individual items to suit full rebuilds or targeted repairs
