🔌 Function

Supports one connecting rod on the crankshaft journal and maintains the lubricating-oil clearance required for smooth rotation and load transfer.

⚠️ Common Signs of Failure

• Low engine oil pressure after the lubrication system has been checked
• Deep crankshaft knock or rumble under load
• Copper-coloured or bearing-metal particles in the oil or filter
• Crankshaft journal clearance exceeds the workshop limit
• Bearing shells are scored, overheated, fatigued or contaminated

🛠️ Service Notes

• Work scrupulously clean — a bearing will not tolerate grit — and inspect the shaft and housing seats before fitting; if they are worn, fretted or out of shape the new bearing will not last, however well it goes in
• Press or draw the bearing on by loading only the race being fitted, squarely, so the load never passes through the balls or rollers, and never strike a bearing directly
• Fit everything supplied in the kit as a set — do not pair a new bearing with an old race, and keep matched pairs together and the right way round
• Lubricate with the grease or oil specified for that position before the bearing is loaded, and set any preload or end float to the figure and method given in the workshop manual for your engine
• Turn the assembly by hand to feel and listen for roughness before it goes back into service, and check it for heat after the first run under load
