Information
Gearbox cylindrical roller bearing.
A cylindrical roller bearing used inside the gearbox to support rotating shafts (often the mainshaft or pinion shaft, depending on application) while allowing them to handle significant radial loads without excessive friction or wear.
Fits:
Porsche 911 1965 - 1973 MAN
Porsche 911 1965 - 1983 SPM
Porsche 914 1970 - 1976
Porsche 914-6: SPM 1970 - 1976
Diagram ref no 27
This cylindrical roller bearing supports the rotating gearbox shaft under high radial load, ensuring it stays properly aligned for smooth and quiet gear operation. It reduces internal friction and wear by providing a precise rolling surface, and it restores correct transmission performance when the original bearing has become worn, noisy, or damaged.
A worn gearbox bearing can cause shaft misalignment, leading to gear noise, rough shifting, and accelerated wear of gears and synchronizers. As the bearing deteriorates, it may generate metal debris, increase friction, and place additional stress on internal components. Replacing it with a fresh bearing restores stability inside the transmission, reduces noise, and helps prevent costly damage or failure.
Replace this bearing if:
• You hear whining, rumbling, or growling noises from the gearbox
• There is noticeable shaft play or misalignment during rebuild
• Gear changes feel rough or noisy due to misaligned shafts
• Gearbox oil shows metal particles or bearing debris
• Rebuilding or refreshing a 901 / 915 transmission
