EXEDY Car Parts
Exedy on AutoMotoPart is an eight-part manual-transmission clutch range. Seven kits carry the codes FJK2046, FMS2165, MZK2124, OPS2121, RNK2056, SZK2009 and SZK2016. The evidenced descriptions show disc diameters from 180 to 240mm and spline counts from 18 to 26. Five are described as three-piece kits with a release bearing; FMS2165 and OPS2121 are two-piece kits without one. CSC407 is a separate aluminium concentric slave cylinder with a stated 31mm bore.
Choose by registration or VIN only as a starting point, then confirm build date, engine code, gearbox type and code, flywheel arrangement, spline, diameter and every kit component against Exedy catalogue data. The current AutoMotoPart selection contains 8 Exedy items, led by 7 clutch kit entries, 1 central slave cylinder, clutch entry. These Exedy figures describe the range on this page rather than every product the brand may make elsewhere.
A clutch kit is not complete for a repair merely because it contains a cover, disc and bearing. Some vehicles use an external release bearing, while others use a concentric slave cylinder inside the bellhousing. Evidence identifies OPS2121 for a dual-mass-flywheel arrangement and FJK2046 for an engine without one, but that distinction must be verified on the exact vehicle. Assess the existing flywheel to its manufacturer procedure, replace a failed dual-mass unit rather than machining it and do not convert to single mass unless using a specifically engineered matched package.
Diagnose the original failure before removal: oil leakage, hydraulic faults, cable adjustment, worn fork or guide, misalignment and flywheel damage can ruin a new clutch. Compare all parts before fitting, clean the bellhousing and input splines without contaminating friction faces, check the disc orientation and centre it with a suitable alignment tool. Tighten the cover gradually in the specified diagonal sequence with hand tools and correct torque. Never draw the gearbox onto the engine using its bolts or let its weight hang on the clutch disc. Replace and bleed a CSC by its exact procedure, verify pedal and release operation and follow Exedy's bedding guidance. Clutch replacement is heavy, safety-critical work requiring proper support and competence.

Exedy: understand the range before choosing
Exedy supplies original-equipment and aftermarket clutch components. The AutoMotoPart range contains seven application-specific clutch kits and one CSC407 central slave cylinder. Kit codes, disc diameter, spline count, bearing contents, transmission details and dual-mass-flywheel arrangement vary, so the complete vehicle and transmission specification must match before the gearbox is removed.
AutoMotoPart currently lists 8 Exedy items. The largest Exedy groups are 7 clutch kit entries, 1 central slave cylinder, clutch entry. Exedy totals can change, so a category count is orientation rather than proof that a particular reference suits a vehicle, workplace or job. The exact Exedy listing, its current technical information and the item in front of you must agree.
What the Exedy page actually covers
| Product group in this range | Current entries | Selection focus |
|---|---|---|
| Clutch Kit | 7 | Match each Exedy code to VIN, build date, engine, gearbox code and transmission type before ordering. |
| Central Slave Cylinder, clutch | 1 | Confirm disc outer diameter, spline count and hub orientation against the removed and catalogue parts. |
Seven of eight items are clutch kits and one is a CSC. Evidence shows five three-piece kits with bearings and two two-piece kits without bearings. Disc diameters span 180, 190, 215, 225 and 240mm, with multiple spline counts and bolt circles. One description specifies a six-speed B6 gearbox and a build-date boundary, demonstrating why code-level fitment is essential.
Build a reliable shortlist
Record the full VIN, registration, build month, engine and transmission codes. Establish whether the vehicle remains in original specification and whether a prior single-mass conversion, gearbox swap or engine change has occurred. Compare Exedy code and technical notes before treating dimensions as confirmation.
| Check | Why it matters | Useful evidence |
|---|---|---|
| Application | Similar models can use different clutches across build dates and gearboxes | Exedy catalogue match using VIN, engine and gearbox code |
| Disc specification | Diameter and spline must both fit while hub orientation clears | Part code, tooth count, outer diameter and trial comparison |
| Kit contents | Two-piece and three-piece kits do not include the same release parts | Box contents and full release-system layout |
| Flywheel | Single- and dual-mass systems use different clutch damping | Original design, condition limits and approved replacement package |
| Hydraulics | An internal CSC leak requires another gearbox removal | Master, lines, CSC or external cylinder and bleed procedure |
| Installation | Misalignment or uneven tightening can distort parts and damage splines | Alignment tool, dowels, sequence, torque and lifting support |
Do not infer fit from disc diameter alone. Two 225mm kits can differ in spline, cover height, release geometry, bolt circle, flywheel and transmission. A dimensional near-match can bolt up yet fail to release correctly.
Two-piece and three-piece clutch kits
FJK2046, MZK2124, RNK2056, SZK2009 and SZK2016 are evidenced as three-piece kits with a bearing. FMS2165 and OPS2121 are described as two-piece kits without a release bearing. Open the box before dismantling and identify cover, driven plate and any bearing or accessory. Compare codes and physical features with catalogue illustrations without placing greasy parts on friction faces.
A missing bearing in a two-piece kit may be intentional because the vehicle uses a separate release component or CSC. It is not permission to reuse a worn unit. Conversely, an included conventional bearing does not replace a leaking hydraulic cylinder elsewhere in the system. Plan all related components and fluids before the gearbox is on the floor.
Application, disc orientation and alignment
Exedy's general instructions require confirming the application and checking that the disc slides freely on clean input splines before installation. Use only the small amount and type of high-temperature grease directed, then remove surplus so it cannot reach the lining. Inspect the disc marking and hub projection because a reversed plate may foul the flywheel or cover.
Centre the disc with a correct alignment tool while positioning the cover over clean flywheel dowels. Start every fastener by hand and tighten gradually in a diagonal sequence to the vehicle specification. Do not use an impact tool on the cover. When refitting, align and support the gearbox independently; never use bellhousing bolts to force a misaligned input shaft through the disc hub.
Flywheel and dual-mass checks
FJK2046 is described for an engine without a dual-mass flywheel, while OPS2121 is described for one with a dual-mass flywheel. This is a major system distinction, not an optional accessory. A DMF contains internal damping and must be assessed to its exact movement, leakage and surface limits. Exedy warns against grinding or machining a worn DMF.
A conventional flywheel may require approved resurfacing to the correct step and finish, or replacement if cracked or outside limits. Follow the factory method, replace bolts where specified and preserve timing or sensor features. A single-mass conversion changes vibration behaviour and must be an Exedy-approved matched cover, disc, bearing or CSC and flywheel package for the application, never a mix assembled by dimensions.
CSC407 and the release system
CSC407 is a separate central slave cylinder for a specific manual-transmission application, evidenced with aluminium construction and a 31mm bore. A CSC combines hydraulic slave and release-bearing functions around the input shaft. Because replacement requires gearbox removal, inspect it whenever the clutch is accessible and follow application guidance rather than comparing bore alone.
Check the master cylinder, reservoir, pipes, connectors and any damper for contamination or restriction. Keep hydraulic fluid off clutch linings and painted surfaces. Fit the CSC squarely with new seals and fasteners as specified; some designs require spacers or strict stroke limits. Bleed using the vehicle and Exedy method without over-travelling the cylinder, then confirm leak-free movement before final road testing.
Diagnosis, installation and bedding
Before removal, note whether the symptom is slip, drag, judder, noise, heavy pedal or poor gear engagement. Inspect engine and gearbox seals, mounts, crankshaft end float where relevant, release fork, pivot, guide tube, spigot support and bellhousing dowels. Correct the cause; replacing friction parts alone will not cure oil contamination or hydraulic travel loss.
Degrease appropriate surfaces, keep dust controlled and avoid compressed-air exposure to old friction material. Support the vehicle, engine and gearbox with rated equipment. After assembly, adjust any cable or free play to specification, bleed hydraulics and verify reverse and first-gear selection while stationary. Follow Exedy's run-in guidance, avoid deliberate slipping or high-load launches and investigate abnormal release or vibration promptly.
From identification to a checked result
| Stage | Good practice for this range | Mistake to avoid |
|---|---|---|
| Diagnose | Identify slip, drag, noise or hydraulic cause before removal | Ordering a clutch solely from symptoms |
| Confirm | Match Exedy code, vehicle build, gearbox, flywheel and contents | Using diameter as the only fitment check |
| Prepare | Inspect flywheel, seals, release system, splines and dowels | Fitting new friction parts over unresolved leaks |
| Install | Orient and align the disc, tighten evenly and support gearbox | Pulling the gearbox in with bellhousing bolts |
| Commission | Bleed or adjust, verify release and follow run-in guidance | Applying full load before function is confirmed |
Record the Exedy part numbers, removed-part markings, flywheel measurements, release components renewed and installation torque references. This evidence is important if a later concern needs to be separated from application or installation error.
Reading real Exedy references
The Exedy names below are examples from the current range and show why the complete description matters. They are not universal Exedy recommendations and should not be treated as a fitment list. Within Exedy, a shared family word can conceal a different dimension, connector, material, pack format, operating condition or installation side.
| Example listing | What to verify beyond the name |
|---|---|
| Exedy CSC407 Central Slave Cylinder, clutch | Exedy kit or CSC code, VIN, build month, engine, gearbox type and code |
| Exedy FJK2046 Clutch Kit | Disc diameter, spline teeth, hub direction, cover and bolt circle |
| Exedy FMS2165 Clutch Kit | Two- or three-piece contents, release bearing, fork or concentric slave cylinder |
| Exedy MZK2124 Clutch Kit | Single- or dual-mass flywheel, surface condition, bolts, alignment and bleed procedure |
| Exedy OPS2121 Clutch Kit | Exedy kit or CSC code, VIN, build month, engine, gearbox type and code |
| Exedy RNK2056 Clutch Kit | Disc diameter, spline teeth, hub direction, cover and bolt circle |
| Exedy SZK2009 Clutch Kit | Two- or three-piece contents, release bearing, fork or concentric slave cylinder |
| Exedy SZK2016 Clutch Kit | Single- or dual-mass flywheel, surface condition, bolts, alignment and bleed procedure |
The seven kit codes are distinct applications even where diameter or bearing description overlaps. Retain the complete Exedy code on the job card and compare all removed parts before installation begins.
Common errors around Exedy products
- Selecting an Exedy clutch kit from vehicle model or disc diameter without gearbox and build details.
- Assuming every kit includes a release bearing or concentric slave cylinder.
- Installing the driven plate backwards or without accurate spline alignment.
- Machining a dual-mass flywheel or mixing it with an unapproved clutch package.
- Reusing a suspect CSC because it is not included in the two-piece kit.
- Contaminating friction material with grease, oil, cleaner or hydraulic fluid.
- Using impact tools or tightening the pressure plate unevenly.
- Drawing the gearbox onto the engine with bolts while its input shaft is misaligned.
Exedy questions and answers
Q: What Exedy products are available here?
A: The range contains seven coded clutch kits and one CSC407 central slave cylinder.
Q: Do all Exedy kits contain three parts?
A: No. Five are described as three-piece with bearings and two as two-piece without bearings.
Q: Can a clutch be chosen by registration alone?
A: Use it as a starting point, then verify VIN, build month, engine, gearbox code and vehicle modifications.
Q: Does matching disc diameter prove fit?
A: No. Spline, cover height, bolt circle, hub, release system and flywheel must also match.
Q: Which kit descriptions mention flywheel type?
A: The evidence marks FJK2046 without a dual-mass flywheel and OPS2121 with one.
Q: Should a dual-mass flywheel be machined?
A: Exedy advises against machining or rebuilding a worn DMF; assess and replace it by the exact procedure.
Q: What is a concentric slave cylinder?
A: It is an internal hydraulic release unit positioned around the gearbox input shaft.
Q: Should the CSC be checked during clutch replacement?
A: Yes. Its condition and complete hydraulic system should be assessed while gearbox access is available.
Q: Why is clutch-disc orientation important?
A: A reversed hub can foul the flywheel or pressure plate and prevent correct release.
Q: Why use an alignment tool?
A: It centres the disc so the gearbox input shaft enters without spline damage or force.
Q: Can bellhousing bolts pull the gearbox into place?
A: No. Support and align the gearbox; forcing it can bend the disc or damage splines and casing.
Q: What must be checked after fitting?
A: Verify hydraulic bleeding or adjustment, pedal and release action, leaks, gear selection and the specified run-in process.
