Clutch Housing / Gearbox Bell Housing SU00200667 For HINO 300 Euro-4 N04C & TOYOTA Dyna/Toyoace — OEM-Grade Structural Casting, Direct Fit Transmission Housing

The Clutch Housing / Gearbox Bell Housing with OEM reference SU00200667 is a verified structural transmission component for HINO 300 (Euro-4) light-duty trucks equipped with the N04C (4.0L) diesel engine. Confirmed cross-platform fitment extends to TOYOTA Dyna / Toyoace applications (including the XZC675 chassis) within the 2011/07 – 2014/09 production window.

This component serves as the structural bridge between the engine block and the transmission gearbox. It encloses the clutch assembly, provides precise alignment between the engine crankshaft and the transmission input shaft, and carries the starter motor mounting provision. In Russian-market parts catalogs, SU00200667 is listed under both "КОРПУС СЦЕПЛЕНИЯ" (clutch housing) and "Колокол КПП" (gearbox bell housing) — two terms describing the same functional component: the bell-shaped housing that mates the engine to the gearbox.

This housing is a load-bearing structural casting, not a wear item in the conventional sense. It is replaced when damaged in a collision, cracked from driveline stress, or when the bearing bore or alignment dowel provisions are worn beyond service limits. The part is supplied as an OEM-grade aftermarket replacement, with cross-references to SU002-01131, SU002-01091, SU002-00165, and 8972636503 confirmed across multiple independent supplier catalogs.

• Part Function & Terminology Verified: SU00200667 is listed as "КОРПУС СЦЕПЛЕНИЯ" (clutch housing) by inodetal.ru, "Колокол КПП" (gearbox bell housing) by dakar-parts.ru, and "Корпус КПП" (gearbox housing) by diesel-dv.ru. All three terms converge on the same engine-to-transmission bell housing.
• OEM Cross-Reference Group Verified: SU00200667, SU002-01131, SU002-01091, SU002-00165, and 8972636503 are consistently grouped as interchangeable/related references across diesel-dv.ru and dakar-parts.ru.
• Vehicle Coverage Verified: HINO 300 (Euro-4) confirmed across Russian-market Hino parts catalogs. TOYOTA Dyna/Toyoace XZC675 confirmed via Toyota EPC data with the same part number SU002-00667 under "HOUSING, CLUTCH", production window 2011/07 – 2014/09.
• Engine Association (Reference): N04C (4.0L) is the primary diesel engine for the Euro-4 HINO 300 platform. The broader Hino 300 engine range includes 14B (3.7L), W04D (4.0L turbo), 15B-FTE (4.1L), and S05C (4.6L), but SU00200667's confirmed application is the Euro-4 N04C platform.
• Transmission Family Coverage (Reference): HINO 300 Euro-4 generation uses manual transmissions including M550 / MYY5A and MYY6S, plus H350/H351/H260 6-speed units. The clutch housing must match the specific transmission bolt pattern — confirm the transmission code at inquiry.
• Market Availability Verified: SU00200667 is actively listed by multiple Russian and international Hino parts distributors, with brand-new and used (Б/У) options available.
• Material & Net Weight NOT Publicly Disclosed: Public supplier listings for SU00200667 do not publish material specification or net weight. Confirm these at inquiry — do not assume grey cast iron or a specific weight without supplier documentation.

• Cracks in the bell housing body: Visible cracks radiating from the transmission mounting face, starter mounting ears, or clutch fork pivot area — typically caused by driveline vibration, misalignment, or impact damage.
• Worn or elongated alignment dowel holes: The dowels that align the housing to the engine block can wear, causing transmission misalignment, difficulty engaging gears, or abnormal clutch wear.
• Damaged transmission mounting face: A distorted or corroded mounting flange prevents the gearbox from seating squarely, leading to oil leaks at the housing-to-transmission joint and input shaft bearing stress.
• Starter motor mounting ear damage: A cracked or stripped starter mounting provision prevents the starter from engaging the flywheel correctly, causing grinding or no-crank conditions.
• Clutch fork pivot wear: An elongated or cracked pivot ball seat inside the bell housing causes poor clutch release and pedal feel changes.
• Oil seepage at the housing-to-engine or housing-to-transmission joint: A warped or cracked mating surface allows gear oil or engine oil to migrate, indicating the housing no longer seals correctly.

• Transmission code is the second critical check: HINO 300 Euro-4 can be equipped with different manual transmissions (M550/MYY5A, MYY6S, H350/H351/H260). The clutch housing bolt pattern must match the specific gearbox. Provide the transmission code or a photograph of the original housing's transmission face at inquiry.
• Euro-4 vs. Euro-3 boundary: SU00200667 is confirmed for the Euro-4 platform. Euro-3 HINO 300 applications use different clutch housing references (e.g., 3111136400 / 3111137100 per dakar-parts.ru). Do not interchange Euro-4 and Euro-3 housings without confirming the engine and transmission interface.
• TOYOTA Dyna/Toyoace cross-brand coverage: The same housing is listed under Toyota EPC for the XZC675 chassis (2011/07–2014/09) as "HOUSING, CLUTCH". This makes the part a cross-brand SKU for distributors serving both HINO and Toyota light-duty truck fleets.
• Material and weight must be confirmed: Because public data does not specify whether this housing is cast iron, cast steel, or aluminum, do not quote freight or installation tooling requirements without supplier confirmation of net weight and material.

1. Confirm the required housing first: Verify that the original unit is the Euro-4 clutch housing and that the replacement matches the transmission bolt pattern. Compare the dowel hole positions and starter mounting ear configuration.
2. Support the transmission: Use a transmission jack to support the gearbox before removing the housing-to-engine bolts. Do not let the transmission hang on the input shaft — this can damage the clutch disc and input bearing.
3. Remove the transmission and clutch: Separate the gearbox from the engine, then remove the clutch pressure plate and disc to access the bell housing. Note the orientation of the release bearing and fork.
4. Remove the old housing: Unbolt the housing from the engine block and transmission (as applicable). Note the location of any shims, dowels, or alignment sleeves.
5. Clean the mating surfaces: Remove all old gasket residue, corrosion, and oil film from the engine block face and the transmission face. A clean, flat surface is essential for correct alignment and sealing.
6. Install the new housing: Position the SU00200667 housing on the engine block dowels. Verify that the dowels engage cleanly — do not force the housing onto the block.
7. Torque the housing bolts: Tighten the housing-to-engine bolts in a cross pattern to the workshop manual specification.
8. Reinstall the clutch and transmission: Reinstall the clutch assembly and mate the gearbox to the housing. Verify that the input shaft splines engage the clutch disc smoothly — do not force the transmission into place.
9. Check alignment and runout: After assembly, verify that the transmission input shaft rotates freely and that there is no binding. If available, check bell housing runout against the crankshaft centerline.
10. Refill and road test: Refill the transmission with the specified gear oil. Road-test the vehicle, checking for smooth clutch engagement, all gear selection, and absence of noise or vibration.

• Inspect the clutch housing area at every clutch or transmission service — look for cracks, oil seepage, or loose mounting bolts.
• Check starter mounting bolts for tightness if the starter engages noisily or intermittently — a loose starter can crack the housing ear.
• Monitor clutch pedal feel and gear selection — changes can indicate housing misalignment or dowel wear before a visible crack develops.
• Avoid riding the clutch or aggressive driveline shock — these increase stress on the bell housing and alignment dowels.

• Standard packing: Heavy-duty carton or wooden crate with protective wrapping for a cast structural component. Export pallet available for bulk orders.
• Package contents: 1 × Clutch Housing / Gearbox Bell Housing. Mounting bolts, dowels, gaskets, and clutch components are not included unless explicitly stated — confirm exact package contents at inquiry.
• Set options: Housing only / housing + gasket kit (if available) — specify at inquiry.
• Suitable for: HINO 300 / TOYOTA Dyna driveline repair shops, fleet maintenance departments, transmission rebuilders, spare parts distributors, and export wholesalers serving Southeast Asia, the Middle East, Africa, and Latin America.
