93175343 Clutch Kit: What It Does
A clutch kit is the practical way to replace a clutch. On the 93175343 kit the cover, disc and bearing are matched to each other and to the original flywheel pattern, so the pedal feel and torque capacity stay as designed.
The part is supplied ready to fit, with the dimensions and the interface points matched to the original. Fitting a part that is nearly right is the most common cause of repeat repairs in this area of the driveline or charging system.
Specification Summary
- Pressure plate with matched clamp load
- Friction disc with the original spline count
- Release bearing included
- Alignment tool supplied where required

Application Notes
Fitment follows the assembly, not the badge. Two vehicles of the same model year can use different parts, so check the number on the old unit.
Failure Modes
Clutches wear as a set: the disc lining thins, the pressure plate loses clamp load and the bearing loses grease. Replacing only the disc leaves a weak cover and a noisy bearing behind.
Installation errors account for most early failures: a scored flywheel, a dry spline or bolts tightened in the wrong order.
Fault Symptoms
- Clutch slip under load
- Judder when pulling away
- Noise when the pedal is pressed
- High or low bite point
- Burning smell after hill starts
Checking Before Replacement
Check the release fork, guide sleeve and spigot bearing. These parts are cheap and they decide how the new kit performs.
Replace related wear parts at the same time. A new part fitted against a worn mating surface rarely lasts.
Installation Notes
Clean the flywheel, align the disc with the tool supplied, fit the cover and torque the bolts in a cross pattern. Fit the new bearing, check pedal free play, then bed the clutch in gently for the first few hundred kilometres.

Frequently Asked Questions
How do I confirm the part number?
Read the number from the old unit, not from a catalogue illustration. Compare the key dimensions at the same time.
Can I fit this without special tools?
Most of these parts fit with standard hand tools. A pulley needs a spline holding tool, and a clutch needs an alignment tool.
What else should be replaced at the same time?
Anything that touches the new part: belts and tensioners for a pulley, brushes for a regulator, the disc, bearing and flywheel face for clutch work.
Why did the original part fail?
Wear, heat and misalignment account for most failures. Correct installation and matching numbers prevent a repeat.
The installation of the clutch pressure plate and friction disc (driven disc) is a core part of the clutch assembly process. Three critical principles—coaxial alignment, correct orientation, and standardized torque application—directly determine the clutch’s operational smoothness and service life. Below is a universal standardized installation method applicable to manual - transmission passenger vehicles, including mainstream brands such as MG, Ford, and Peugeot.
Flywheel Face Cleaning: Use a special - purpose cleaner to remove oil stains, rust, and wear debris from the flywheel face. Wipe it dry to ensure no residual grease remains. Employ a dial indicator to measure the flywheel’s axial runout; the maximum allowable value is ≤0.15mm. If the runout exceeds this limit, the flywheel must be ground or replaced. Otherwise, it will lead to clutch judder and abnormal noises.
Pressure Plate Inspection: Check the height difference of the diaphragm spring fingers on the pressure plate; the maximum allowable value is ≤0.5mm. If the heights are inconsistent, correct them using a special tool. Failure to do so will result in incomplete clutch disengagement and difficulty in gear shifting. Ensure there are no cracks or burn marks on the pressure plate’s friction surface.
Friction Disc Inspection: Confirm that the friction disc is free of oil contamination and that its rivets are not exposed (the rivet depth should be ≥0.3mm). Verify that the spline specifications match those of the transmission input shaft, and ensure the disc rotates smoothly without jamming.
Special Tools: Clutch alignment tool (a core tool to ensure coaxiality between the friction disc and the crankshaft), flywheel holding tool (to prevent crankshaft rotation), torque wrench (5–50N・m), and socket set.
Consumables: Lithium - based high - temperature grease (for splines only; never allow contact with friction surfaces) and new pressure plate bolts (it is advisable to replace them once; bolts with anti - loosening design cannot be reused).
The friction disc is usually marked with “Flywheel Side” (facing the flywheel) or “Trans Side” (facing the transmission). Install it strictly in accordance with these markings.
For unmarked discs, determine the orientation based on the following rules:
The side with protruding damping springs faces the transmission.
The side with the longer splined hub faces the transmission.
Reversed installation will cause insufficient clutch travel, failure to disengage, and severe damage to the friction disc due to overheating.
Lock the flywheel with a flywheel holding tool to prevent crankshaft rotation.
Apply a very thin layer of lithium - based high - temperature grease to the friction disc’s splines. Wipe off any excess grease to avoid contaminating the friction surfaces.
Insert the clutch alignment tool into the friction disc’s splines, and then accurately insert the other end of the tool into the crankshaft pilot bearing bore. Adjust the friction disc’s position to ensure it fits perfectly parallel to the flywheel face without tilting or gaps.
Pressure Plate Positioning: Fit the pressure plate smoothly over the outside of the friction disc. Align the pressure plate’s bolt holes with those on the flywheel to ensure the pressure plate fully contacts the flywheel face with no gaps.
Standardized Bolt Tightening (Core Step):
Hand - tighten all pressure plate bolts (typically 6 bolts) until the pressure plate is just secured without looseness.
Tighten the bolts in 3 sequential passes following a crisscross pattern using a torque wrench. Tighten them to the specified torque (the general value is 25–30N・m; refer to the vehicle - specific manual for the exact value, with a torque deviation ≤±2N・m).
After tightening, recheck the coaxiality of the friction disc and pressure plate. There should be no noticeable looseness when wiggling the alignment tool.
After confirming that all pressure plate bolts are properly tightened, slowly pull out the alignment tool vertically. Avoid prying it at an angle or pulling it forcefully, as this may displace the friction disc.
Manually rotate the pressure plate to check that the friction disc operates without jamming or uneven wear, and that the diaphragm spring fingers move freely without sticking.
This set of precautions focuses on four core principles: orientation compliance, coaxial alignment, torque control, and contamination prevention. It refers to the general technical specifications for automobile clutch installation and the service manuals of mainstream vehicle manufacturers, and is applicable to the assembly of pressure plates and friction discs in manual - transmission passenger vehicles.
Oil stains, water stains, and metal debris must not remain on the flywheel face, pressure plate friction surface, and friction disc friction surface. Use a special - purpose clutch cleaner for cleaning; gasoline and diesel are prohibited (they tend to leave an oil film that causes clutch slippage). After cleaning, wipe the surfaces dry with a clean, lint - free cloth to avoid fiber residue.
The flywheel’s axial runout must be ≤0.15mm. Forced installation is strictly forbidden if the runout exceeds this limit, as it will lead to clutch judder and abnormal noises, and in severe cases, uneven wear of the friction disc. The height difference of the diaphragm spring fingers on the pressure plate should be ≤0.5mm. If the heights are inconsistent, correct them with a special tool; tapping to correct is not allowed (it may cause the spring to break).
The depth of the friction disc rivets should be ≥0.3mm. If the rivets are exposed (flush with or protruding from the friction surface), the friction disc must be replaced immediately, otherwise the friction surfaces of the flywheel and pressure plate will be scratched. Check the fit clearance between the friction disc splines and the transmission input shaft; the disc should rotate smoothly without jamming. If the clearance is too large, replace the friction disc.
