Subaru WRX Clutch cable adjustment

When does your Subaru WRX clutch cable need adjusting?

Driving a manual can be fun, but that fun can come to a halt in stop-start traffic. That’s when you get a little sick of pushing that clutch in and out hundreds of times to move one kilometre.

Have you ever wondered how that affects your clutch and how many times you can perform that action before the clutch wears out? One of the joys of driving a manual is that you have a wonderful cable that can be adjusted as the clutch wears.

This cable gives the clutch a little bit more life before it dies for good.

If your Subaru WRX has an automatic transmission then it won't have a clutch cable but if it is a manual transmission then it might and it may need adjusting.

Manual Subaru WRX's have a hydraulic or manual clutch, which have the job of smoothly connecting the engine torque power to the driveshaft. A hydraulic clutch is generally self-adjusting while a manual clutch is adjusted by a cable.

So why would you need to adjust a clutch cable?

Due to rotating components engaging together to transfer power, there is friction and wear. Over time, this wear creates space between components and engaging the clutch becomes more difficult.

A cable connects the clutch pedal and the fork, which is a lever attached to the clutch. When a driver pushes on the clutch pedal it puts tension on the cable, moving the fork, which engages the clutch.

When adjusting the clutch cable the objective is to adjust the play between the pedal and the clutch lever just enough to allow the clutch to engage better.

Eventually, however, the Subaru WRX clutch cable won’t be able to adjust any further and the clutch will have to be replaced. In saying all that, sometimes the culprit can be the clutch cable itself, as it may have just stretched over time.

If you find the clutch pedal engaging earlier when you push the pedal, then the clutch cable needs to be adjusted.

When does your clutch cable need adjusting?:

• Your foot is high up on the clutch pedal when the clutch engages
• The clutch engages too low on the pedal, this happens when the cable has been adjusted too far
• The Subaru WRX can’t get into reverse and the clutch may be disengaged all the time, this happens when the cable is tightened too much
• If the clutch pressure plate or throw-out bearing were replaced recently, then the clutch cable may need adjusting.
• When replacing a clutch slave or master cylinder, the clutch cable may also need adjusting

The cable can only be adjusted so many times. Eventually, the clutch will need to be replaced

If the clutch engaging system isn’t operating optimally, then the greater the chance of wear and strain on other components and more expensive repairs later.

If you can prolong the life of your clutch as long as possible, then do it - it could potentially save you thousands.
