323001263 - E010 CLUTCH PEDAL HARDENING

Test results
0PRELIMINARY CHECKSAll OKProblems encounteredOperation
Check whether there is excessive resistance when the clutch pedal is pressed.N. B.: Since this symptom is subjective, make sure that there is actually hardening compared with the previous so-called normal situation or compared with similar vehicles.Move on to Step 1
1CLUTCH LEVER TRAVEL CHECKAll OKProblems encounteredOperation
Check, inside the engine compartment, that when the clutch pedal is pressed the clutch control lever on the gearbox completes the correct travel.Move on to Step 3Clutch lever on gearbox travel incompleteMove on to Step 2
2CLUTCH PEDAL CHECKAll OKProblems encounteredOperation
Clutch pedal disconnected from transmission    Op. 3330B26 CLUTCH PEDAL - R+R check that the travel is free and there is no sticking or hardeningMove on to Step 3Clutch pedal clearance or hardeningReplace the pedal    Op. 3330B26 CLUTCH PEDAL - R+R
3VISUAL INSPECTION FOR LEAKS OR SEEPAGEAll OKProblems encounteredOperation
- Visually inspect the operating cylinder and pipes- Check that there is no seepage, leaks or damageMove on to Step 4Leaks, damage or seepage from pipes and/or hydraulic connectorsRepair the defective or damaged components
4CHECK FOR AIR IN THE HYDRAULIC CLUTCH CIRCUITAll OKProblems encounteredOperation
Using the operating cylinder bleed screw, check that there is no air in the circuitMove on to Step 5Air in the circuitBleed the air
5CLUTCH CONTROL CYLINDER CHECK (ON VEHICLE)All OKProblems encounteredOperation
- Release the cylinder from the clutch control lever, keeping it connected to the hydraulic system.- Press the pedal, producing thrust pressure and check the push rod travel.- Using a drift, retract the push rod, checking that it travels freely.Move on to Step 7Clutch control cylinder malfunctionRemove the clutch control cylinder and move on to Step 6
6CLUTCH CONTROL CYLINDER CHECK (WITH GEARBOX REMOVED)All OKProblems encounteredOperation
With the part at the bench, apply pressure (using compressed air) and check the push rod travel (the test mirrors what was done in the vehicle).N.B.: This test is designed to ensure that the problem is due to the cylinder and not to the pipes or the pump.Move on to Step 7Clutch control cylinder malfunctionReplace the clutch control cylinder
7CLUTCH PEDAL TRAVEL CHECKAll OKProblems encounteredOperation
With the system disconnected, check that the travel is correct when the pedal is pressed and releasedMove on to Step 81. Hydraulic pump malfunction2. Hose from clutch reservoir to pump worn or distorted3. Delivery hose to clutch control cylinder worn or distorted1. Replace the pump    Op. 1820B20 MASTER CYLINDER (PUMP) - R + R 2. Replace the hose    Op. 1820B40 HOSE FROM CLUTCH RESERVOIR TO MASTER CYLINDER (PUMP) - R + R 3. Replace the hose
8PRESSURE PLATE LEVER AND BEARING CHECK (WITH GEARBOX REMOVED)All OKProblems encounteredOperation
After the gearbox has been removed, check that there is no hardening of the lever (as a result of dirt or insufficient greasing) and that the pressure plate bearing slides freely in its housing and shows no signs of damage.Move on to Step 91. The presence of dirt or wear due to insufficient greasing does not allow the plate bearing to slide correctly2. Clutch release fork half-shells worn/broken1. Replace the faulty or damaged components2. Replace the release fork half-shells
9CLUTCH ASSEMBLY CHECKAll OKProblems encounteredOperation
Visually inspect the condition of the clutch assembly, making sure it is not broken (pressure plate) and/or showing signs of obvious deterioration (plate).Measurements using the gauge as in the manual.Move on to Step 10Obvious deterioration of the clutch plate and/or pressure plate brokenReplace the assembly
10CLUTCH SLIDING SPLINED HUB CHECKAll OKProblems encounteredOperation
Check the following, in order:- for excess grease on the clutch plate hub bushes and the gearbox main shaft;- the condition of the main shaft and hub.Move on to Step 11Main shaft damaged, hub worn, excess grease on the bushesReplace the hub and/or main shaft
11FLYWHEEL CONDITION CHECKAll OKProblems encounteredOperation
Check the condition of the flywheel. In particular, check:- the state of the surface;- wear;- cuts;- presence of grease/oil on the disc surfaces;- signs of overheatingEnd of diagnosis1. Flywheel damaged2. Presence of dust in the flywheel friction seal1. Replace the flywheel2. Remove the dust from the flywheel friction seal.
