Starter Motor M8T85271 M8T85271B ME240241 ME240251 ME241359 ME241622 For MITSUBISHI 4M51 4M50 Fuso Canter FE50E FE69E Rosa BE632 — 24V 11T CW Heavy-Duty Direct Fit

The Starter Motor with cross-reference numbers M8T85271 / M8T85271B / ME240241 / ME240251 / ME241359 / ME241622 is a verified heavy-duty replacement for MITSUBISHI 4M51 (5.25L) and 4M50 (4.9L) diesel engines. This starter is a critical electrical component responsible for cranking the engine at sufficient speed to initiate combustion — particularly demanding on 24V commercial truck platforms where cold-start reliability and high compression ratios are essential.

The 4M51 is a 5,250 cc inline-4 diesel engine widely used in MITSUBISHI Fuso Canter medium-duty trucks (FE50E, FE69E, FE82E, FG73E, and related chassis) and Fuso Rosa buses (BE63D, BG64E, BE632). The 4M50 family (4.9L) shares the same starter mounting and electrical interface, covering Canter FE70D, FE71D, and FG70D applications. This starter motor is the 24V, 11-tooth, clockwise (CW) rotation unit specified for these platforms.

• Voltage & Teeth Verified: 24V, 11 teeth (11T), CW rotation — confirmed across GNT, KST, AS-PL, and Kinmax technical specifications for the M8T85271 platform.
• Power Rating (Variant-Dependent): 3.7kW is the most widely cited rating for the standard M008T85271 / M8T85271 reference. Some supplier catalogs list 5.0kW for the same cross-reference family, and 3.2kW for certain aftermarket alternatives. Confirm against original unit before ordering.
• Rotation Verified: Clockwise (CW) — consistent across all major aftermarket references.
• Mounting Configuration Verified: 4 mounting holes; critical dimensions include FD 66 mm, Size A 18 mm, OD 40 mm, H1 13.5 mm.
• OEM Cross-Reference Verified: Primary references M8T85271, M8T85271B, ME240241, ME240251, ME241359, ME241622. Additional interchangeable references include M008T85271, M008T85271B, M008T85771, M8T85771, M8T85771AM, ME221562, ME225158, ME241022, ME241896.
• Multi-Platform Application: Confirmed compatible with MITSUBISHI Fuso Canter (FE50E, FE69E, FE82E, FG73E, and a wide range of FE chassis with 4M51) and Fuso Rosa (BE63D, BG64E, BE632) platforms. The 4M50 engine family (Canter FE70D, FE71D, FG70D) is also covered under the same cross-reference set.

• Slow or labored cranking: Engine turns over noticeably slower than normal, especially when cold — indicates worn brushes, armature degradation, or solenoid contact wear.
• Clicking or single-click no-crank: A loud click from the starter area but no engine rotation — solenoid contacts may be burned, or the starter drive is not engaging the flywheel.
• Grinding noise during cranking: The starter drive (Bendix) fails to mesh cleanly with the flywheel ring gear — can be caused by a worn drive gear or misaligned starter mounting.
• Starter runs but does not engage engine: The starter motor spins but the engine does not turn — indicates a failed overrunning clutch in the drive assembly.
• Intermittent no-start: Starter works intermittently, often after heat soak — a classic sign of worn solenoid windings or heat-sensitive electrical degradation.

Confirmed Fitment Sources: JUBANA starter catalog lists Canter FE50E, FE512, FE51E, FE52E, FE532, FE53E, FE542, FE562, FE59E, FE62E, FE632, FE63D, FE63E, FE652, FE662, FE70D, FE70E, FE71D, FE72D, FE72E, FE642, FE69E, FE71E, FE73D, FE73E with 4M51 and 4M50T engines. GNT confirms Canter FE50E, FE69E, FE82E, FG73E, FG82D, FG70D, Fighter FK71D, Rosa BE63D, and Rosa BG64E. AS-PL and Kinmax confirm the 24V / CW / 11T configuration for the M8T85271 family.

Each starter undergoes 100% load testing before packaging. Manufacturing conforms to supplier-specific quality management standards (ISO/TS16949 where applicable — confirm at inquiry).

1. Safety first: Disconnect both battery negative terminals (24V systems typically use two 12V batteries in series). Wait for any stored energy in capacitors to dissipate if applicable.
2. Label and disconnect wiring: Note the positions of the B+ (main power) cable, solenoid signal wire, and any ground straps. Do not allow the B+ cable to contact ground — it is unfused and can cause a dead short.
3. Remove mounting bolts: Support the starter weight before removing the final bolt. Note any shims between the starter and bellhousing.
4. Inspect flywheel ring gear: With the starter removed, inspect the ring gear teeth for excessive wear, chipping, or missing teeth. A damaged ring gear will quickly destroy a new starter drive.
5. Compare new and old units: Before installation, verify that the new starter's mounting flange, drive gear tooth count (11T), and terminal positions match the original.
6. Install new starter: Position the starter on the bellhousing, insert mounting bolts, and torque to the Fuso workshop manual specification. Do not omit any factory-installed shims — incorrect pinion-to-ring gear clearance causes grinding and premature failure.
7. Reconnect wiring: Connect the B+ cable first, then the solenoid signal wire, then ground straps. Tighten all terminals securely — loose B+ connections are a common cause of starter failure and heat damage.
8. Reconnect batteries and test: Reconnect battery terminals. Crank the engine and listen for clean engagement without grinding. If grinding persists, stop immediately and verify shimming and pinion clearance.

• Inspect battery connections at every oil change — corroded or loose terminals reduce cranking voltage and stress the starter.
• Load-test the battery annually — a weak battery causes the starter to draw excessive current and overheat.
• Inspect starter mounting bolts for tightness at every major service — a loose starter can cause misalignment and ring gear damage.
• Replace starter at first sign of intermittent no-crank — continuing to operate with a failing solenoid or drive can damage the flywheel.

• Standard packing: Individual foam-lined carton with terminal protection; wooden pallet available for bulk orders.
