What does a hydraulic throwout bearing do?
The throwout bearing is the last piece in the series of components that composes the clutch linkage from the pedal to the clutch assembly inside the transmission bellhousing. It is a bearing, meaning that it allows interaction between a moving surface and a stationary surface.
How serious is a throw out bearing?
Finally, a bad throw-out bearing can lead to total clutch failure. This is an expensive issue to fix, so it’s important to address signs of throw-out bearing wear early on, before the problem worsens.
How does a hydraulic bearing work?
The Hydraulic release bearings typically work like a mini hydraulic brake system. In HRBs there’s no clutch fork or slave cylinder, rather, the clutch master cylinder applies hydraulic pressure directly to the bearing, engaging the pressure plate fingers, which in turn disengages the clutch disc from the flywheel.
What is a hydraulic release bearing?
RAM hydraulic release bearings, sometimes called hydraulic throwout bearings or concentric slave cylinders, offer flexibility in setting up the clutch system on your early or late model performance car or truck. HD versions offer the utmost in durability and long life over factory hydraulic systems.
Should the throwout bearing touch the pressure plate?
The throw out bearing must NOT ride on the pressure plate.
What causes throw out bearing failure?
Normal Wear and Tear over Time Friction takes its toll every time you drive, gradually wearing away material that changes the size and finish of the bearing. At some point, the fit and finish will no longer fit into the assembly properly, causing the clutch to eventually fail if the release bearing isn’t replaced.
What ruins a throw out bearing?
The bearing may go bad after years of wear and tear or maybe even from damage due to an accident. In any case, you need to get the clutch release bearing replaced as soon as you notice it’s having problems.
How much travel should a hydraulic throwout bearing have?
Typically with OEM applications the throw-out bearing travel is . 440” – . 445”.
How much does it cost to replace a throwout bearing?
The average throw-out bearing replacement cost ranges between $400 and $1500, with almost all of that cost being labor. That’s because an aftermarket throw-out bearing only typically only costs between $10 and $30.
How do you check a throw out bearing?
The most common sign of a bad throw-out bearing is when you hear various noises when you depress the clutch pedal. The rollers within the bearing have a tight tolerance and are supposed to be close together. But if there is too much space between the rollers, then different types of noises will start to be heard.

How far do clutch fingers travel?
Ram recommends single disc clutches have a 0.150-inch gap between the bearing and clutch fingers, while dual-disc sets require a gap of around 0.200-inch. The extra 0.050-inch gap for the dual disc clutch prevents the clutch fingers from hitting the bearing as the clutch discs’ friction material wears.
What happens if a throwout bearing fails?
The more worn down the bearing is, the harder it will become to depress the clutch pedal. It will soon get to a point where you cannot disengage the clutch. Then you won’t be able to drive your vehicle at all since you won’t be able to shift gears.

How often should you grease a throwout bearing?
Using the chart and the formula, the bearing only needs 8 grams of grease every 10,000 hours. If your grease gun delivers around 1.35 grams per stroke, that means the bearing needs 6 strokes every 13 months; you could average it out to a stroke every 8 weeks or so.
What is a throwout bearing and how does it work?
by Pauline Gill. Strateger Graphics. A throwout bearing is a part of an automotive clutch system that temporarily disengages the engine from the manual transmission while shifting. It translates a linear thrust force from the clutch pedal to the spinning clutch plate assembly mounted to the flywheel. It is a thrust bearing with the inner race attached to the clutch throw out arm and the outer race contacting the clutch de-actuation fingers.
How do you know when a throwout bearing is bad?
Stiff or Stuck Clutch. For a throw out bearing to work smoothly,it needs to retain its lubrication properties for as long as possible.
