Understanding Volvo V50 Clutch Slipping: A Case Study

While the focus is on the V70, understanding common issues across Volvo models can be highly beneficial. A recent case highlighted the process of replacing a clutch on a 2010 Volvo V50, a model that shares its platform with the Ford Focus. This particular vehicle, equipped with a 1.6 turbo diesel engine and having covered nearly 160,000 miles, was experiencing a classic symptom of clutch slipping.

The Clutch Replacement Procedure Explained

Replacing a clutch is a complex task that requires precision and the right tools. Here's a detailed breakdown of the procedure, as performed by REPXPERT's Alistair Mason:

Preparation and Access

• Begin by opening the bonnet and removing the battery cover.
• Disconnect the diesel particulate filter (DPF) pressure sensor.
• Remove the battery and its carrier.
• Take off the plastic engine cover and the air filter assembly.
• Crucially, the DPF needs to be lowered to access one of the front bell housing bolts. This involves disconnecting the DPF from the turbocharger by removing the air intake hose, heat shield, and retaining clamp.

Disconnecting Key Components

• Once the DPF is eased down for clearance, focus on the engine bay.
• Disconnect the gear change cables by carefully separating the ball joints and unclipping the outer cables.
• Clamp the hydraulic clutch feed pipe to prevent fluid loss.
• Disconnect the feed pipe from the concentric slave cylinder (CSC) by releasing the retaining clip and securing it in the bulkhead area.
• Gently ease the engine wiring loom back from the bell housing area to gain access to the upper bell housing bolts, then remove them.

Underside Preparations

• Before raising the vehicle further, slacken the front locking wheel bolts and front hub nuts.
• Raise the ramp to waist height, remove both front wheels, and the offside front (O/S/F) wheel arch liner.
• Raise the ramp again to access the underside.
• If fitted, remove the engine under tray.
• Drain the gearbox oil.

Driveshaft and Gearbox Removal

• Release both front bottom ball joints and disconnect them from the hub assemblies.
• The outer driveshaft joints should now ease out of the hub assemblies.
• The nearside (N/S) driveshaft will lever out of the gearbox.
• On the offside (O/S) driveshaft, unbolt the centre bearing from the back of the engine block and then lever it out of the gearbox.
• Remove the vacuum unit attached to the starter motor.
• Detach the three bolts securing the starter motor to the bell housing, the gearbox torque mount, and the lower bell housing bolts.
• Leave the two bell housing bolts at the 3 o'clock and 9 o'clock positions in place, as these will support the gearbox temporarily.
• Support the engine using an axle stand, an engine support subframe, or an engine brace bar.
• Remove the complete gearbox top mounting for better access.
• Support the gearbox with a transmission jack and then remove the final two bell housing bolts (at 3 and 9 o'clock).
• Slightly lower the engine and carefully ease the gearbox away from the engine, then lower it completely when clear.

Clutch and Flywheel Inspection and Replacement

• With the gearbox removed, detach the old clutch assembly from the flywheel. In this case, the clutch friction material was worn down to the lining rivets, indicating it had reached the end of its service life.
• Inspect the dual mass flywheel (DMF). This example showed wear marks from the rivets and signs of overheating, indicated by a 'blued' surface, necessitating its replacement.
• After removing the old flywheel, check the back of the engine for any oil or coolant leaks that could contaminate the new clutch. The rear main oil seal required repair in this instance.

Fitting the New Components

• Fit the new DMF, ensuring correct location and torquing the bolts to the manufacturer's specification using tools like Schaeffler’s DMF Checkpoint app.
• Clean the bell housing thoroughly with brake and clutch dust cleaner.
• Remove the old CSC and ensure the mounting surface for the new CSC is clean.
• Important Technical Bulletins: When handling the new CSC, pay attention to any attached technical bulletins. These may instruct you to discard original fixing bolts or confirm correct sealer application.
• When fitting the new CSC, avoid squeezing the cylinder to prevent internal damage.
• Be careful not to damage the gearbox input shaft seal within the new CSC during installation.
• Fit the new bolts and torque them to the manufacturer's specification.
• Apply a small amount of high-melting point grease to the input shaft splines and slide the new clutch plate onto the shaft. This helps distribute the grease evenly and ensures correct spline fitment. Remove the clutch plate and wipe off excess grease.

Self-Adjusting Clutches: Installation Nuances

The clutch being fitted in this repair was a modern self-adjusting type. These can be identified by a square sprung steel plate controlling the adjuster wheel and feature travel-controlled adjustment, unlike older designs with load-controlled adjustment (often indicated by yellow adjuster rings).

• It is highly recommended to use a self-adjusting clutch mounting tool for installation.
• Ensure the flywheel face is clean before mounting the clutch plate.
• Verify the clutch plate is correctly oriented, with 'Gearbox side' or 'Getriebe Seite' facing outwards.
• Locate and correctly install the clutch pressure plate/cover using the self-adjusting clutch tool.
• Secure the pressure plate with three bolts, remove the tool, fit the remaining three bolts, and torque them to the manufacturer's specification.

Hydraulic System and Final Refitting

• Before refitting the gearbox, it's best practice to flush or change the clutch hydraulic fluid. This is done by draining the fluid from the clutch pipe while topping up the reservoir with fresh fluid until it runs clear. This prevents contamination of the new CSC.
• Check that the alignment dowels are correctly seated in the engine block.
• Refit the gearbox, ensuring correct alignment and angle during installation.
• Reassemble in the reverse order of removal.
• Once the gearbox is bolted and secured, install the hydraulic clutch pipe.
• Bleed the clutch system. This CSC has a two-position pipe connection. Connect the pipe to the first position. Attach a bleed container and pipe to the nipple, remove the clamp, and allow fluid to drain. Once air is dispersed, push the pipe into the second position to shut off the bleed nipple and complete the hydraulic system operation.
• After refitting the driveshafts, replace the gearbox oil with the correct specification and quantity.
• Following battery installation, reset any necessary electrical systems and control units.
