hey guys is the spigot bearing and thrust bearing the same thing or not? my knowledge is that the thrust bearing is the one the clutch fork presses onto and therefore presses the clutch fingers in, and where exactly is the spigot bush/bearing located? is it in the crank or the flywheel? i got the JUN crank and i didnt put one in if its supposed to be in the rear of the crank.

Please update us with how it goes Cruiseliner.. i'm definately interested to see what it could be.. do you think you forgot to put it in when you put the gearbox back in??

A clutch release bearing is different; it will make a chirping or squealing noise as soon as the bearing touches the pressure plate’s diaphragm.
Why does a clutch make a noise when the clutch pedal is completely depressed?
When the clutch is disengaged, the transmission’s input shaft and the engine’s crankshaft are rotating at different speeds. The pilot bearing allows for this difference. This is why a faulty pilot bearing makes its most noise when the clutch pedal is completely depressed and the clutch itself is completely disengaged.
What type of bearings are used in flywheels?
The bearing type can be ball, roller or needle bearings packed in grease. If the manufacturer recommends adding bearing grease, be careful to avoid contaminating the clutch disk or the surface of the flywheel. Pilot bushings are brass and infused with lubrication.
What is a pilot bearing?
The pilot bearing/bushing supports and centres the transmission input shaft and clutch disc. When the clutch is disengaged, the pilot bearing/bushing allows the flywheel to maintain engine RPM while the input shaft is slowing down ...
What happens when a pilot fails?
When the pilot is failing, or has failed, the input shaft will be allowed to walk around causing it to go off centre. When this happens, the transmission input shaft will begin moving around inside the transmission causing the gears and synchronizers to be off centre resulting in the transmission popping out of gear.
Does lubrication increase friction?
Adding lubrication will actually increase friction with these soft metal type bushings. Check with the vehicle manufacturer’s recommendations before adding any lubrication to a pilot bearing. Diagnosing a Faulty Pilot Bearing. A worn or damaged pilot bearing will make a whining or grinding noise.
