The Mitsubishi Triton is a compact pickup truck produced by Mitsubishi Motors. In Japan it was originally known as the Mitsubishi Forte and from 1991 as the Strada. In the United States Chrysler Corporation sold captive imports as the Dodge Ram 50 and Plymouth Arrow truck, and Mitsubishi marketed it as the Mitsubishi Mighty Max until 2002.
For most export markets the name L200 is used though it also been known as the Rodeo, Colt, Storm, Magnum, L200 Strakar (badge used in Portugal since 1999, Strakar is a portmanteau of Strada and Dakar), and others.
Cumulative sales of the first three generations exceeded 2.8 million units around the world.
As of February 2021, the pickup truck is sold in every available Mitsubishi market except the United States, Canada, Japan, India and China. In Japan, it was previously sold at a specific retail chain called Car Plaza.
In 2015, Fiat Professional launched a rebadged version as the Fiat Fullback. In 2016, Ram Trucks launched a rebadged version as the Ram 1200 for the Middle East market. The Dodge Dakota-based Mitsubishi Raider is unrelated to the Mitsubishi Triton.
The fourth generation Triton was released in 2005. Designed by Akinori Nakanishi, it was built exclusively by Mitsubishi's subsidiary in Thailand and was exported to 140 global markets. It was mostly known as L200 except for Japan and its subsidiary countries' markets. The car had a 2.5-litre turbodiesel engine developing 134 kW (180 hp). The base version, available in some markets such as the Dominican Republic, had a 2.5-litre normally aspirated diesel engine and the L200 off-road version called the Savana had 200 hp.
In Japan, the Triton was exclusively equipped with 3.5-litre petrol engine and 4-speed automatic transmission and was sold from 2006 to 2011 - the only pick-up truck in the market at that time (excluding kei trucks). Despite its success overseas, it was a critical failure in Japan as workmen and traders preferred vans and station wagons. As a result, in August 2011 the Triton was pulled out from Mitsubishi's Japanese lineup.

### Throttle Cable on Mitsubishi Triton L200

#### Overview
The throttle cable connects the accelerator pedal to the throttle body of your engine. When you press the accelerator, the cable pulls on the throttle plate, allowing more air (and fuel) into the engine, which increases power and speed.

#### Components of the Throttle Cable System
1. **Throttle Cable**: A flexible cable that transmits movement from the accelerator pedal to the throttle body.
2. **Accelerator Pedal**: The pedal that you press to accelerate the vehicle.
3. **Throttle Body**: The component that controls the amount of air entering the engine. It has a valve (the throttle plate) that opens and closes.
4. **Cable Housing**: A protective sleeve that guides the throttle cable and keeps it from kinking or fraying.
5. **Anchor Points**: Locations where the cable is secured to both the pedal and throttle body.

### How the System Works
1. **Pressing the Accelerator**: When you press the accelerator pedal, the pedal moves downward.
2. **Cable Movement**: This action pulls the throttle cable, which is connected to the throttle body.
3. **Throttle Plate Opening**: The cable pulls on the throttle plate, causing it to open, allowing more air to enter the engine.
4. **Engine Response**: More air leads to more fuel being injected, increasing engine power and speed.

### Why Repair is Needed
1. **Wear and Tear**: Over time, the cable can fray or stretch, leading to slack. This results in delayed throttle response, making the vehicle feel unresponsive.
2. **Binding or Kinking**: If the cable gets pinched or kinked, it can cause the throttle to stick, which is dangerous.
3. **Corrosion**: Rust or dirt can build up in the cable housing, leading to increased friction and failure to operate smoothly.

### What Can Go Wrong
- **Sticking Throttle**: If the cable is damaged or binding, it can cause the throttle to stick open, leading to unintended acceleration.
- **Delayed Response**: A stretched or frayed cable may not respond quickly, making driving less safe.
- **Complete Cable Failure**: A broken cable means you’ll have no throttle control at all.

### Repair Steps
1. **Safety First**: Disconnect the battery to prevent any electrical issues.
2. **Locate the Throttle Cable**: Follow the cable from the accelerator pedal to the throttle body.
3. **Remove the Old Cable**:
- **At the Pedal**: Unclip or unscrew the cable from the pedal assembly.
- **At the Throttle Body**: Loosen the retaining bolt and disconnect the cable from the throttle plate.
4. **Inspect**: Check the cable housing for damage and the anchor points for any obstructions.
5. **Install New Cable**:
- **At the Throttle Body**: Attach the new cable to the throttle plate, ensuring it's secure.
- **At the Pedal**: Connect the other end to the accelerator pedal assembly.
6. **Adjust Tension**: Ensure there is the right amount of slack in the cable to avoid binding. The cable should not be too tight.
7. **Reconnect Battery**: Once everything is in place, reconnect the battery.
8. **Test Drive**: Start the vehicle and test the accelerator to ensure smooth operation and proper response.

### Conclusion
By understanding the throttle cable's role and how to replace it, you can ensure your Mitsubishi Triton L200 operates safely and efficiently. Regular checks can prevent potential issues before they become serious problems.

Brief theory — what the input-shaft bearing does and how it fails
- Function: the input-shaft bearing supports the transmission input shaft radially (and sometimes axially), keeping the shaft concentric with the gearbox casing and allowing smooth rotation with minimal friction. Proper support maintains gear mesh geometry, synchro function and seal alignment.
- Failure modes: wear (race/roller/brinelling), pitting from contamination, lubricant breakdown, excessive radial/axial loads from clutch misalignment, or shaft journal damage. Consequences: whining/growling or rumble at certain speeds, rough or difficult gear engagement, increased gear and synchro wear, metal debris in gearbox oil, excessive input-shaft endfloat or runout.
- Diagnosis indicators (theory): bearing noise that changes with engine speed but not with road speed (if clutch disengaged), play measured at input shaft, metal particles in oil, vibration. Confirm by isolating engine vs drivetrain rotation and by prying/feeling input shaft play with gearbox removed or half-disassembled.

Ordered procedure with theory explained at each stage
1) Preparation and safety
- Theory: correct support and cleanliness prevent secondary damage and contamination.
- Actions: work on flat surface, disconnect battery, lift vehicle safely, support engine/transmission with jack/transmission jack and engine support.

2) Drain gearbox oil
- Theory: prevents oil spillage and allows inspection of contaminants in the oil for diagnosis.
- Actions: remove drain/fill plugs, collect oil and inspect for metal particles.

3) Remove driveline items and separate transmission from engine
- Theory: to access input shaft you must remove clutch/pressure plate/cover or otherwise separate the transmission from the engine so the input shaft can be removed.
- Actions: remove prop shaft/drive shaft, clutch release mechanism, bellhousing bolts, then separate gearbox from engine and lower to a bench. Support clutch assembly if reusing.

4) Remove clutch assembly and pilot/bushing if needed
- Theory: the input shaft passes through/clutches to the pilot bearing; removing them prevents interference and allows inspection of pilot bearing which commonly fails together.
- Actions: remove clutch disc and pressure plate, inspect and replace pilot bearing/bushing if worn.

5) Disassemble gearbox to expose input shaft
- Theory: the input bearing is usually inside the case; full or partial gearbox disassembly is necessary to remove the shaft and bearing. Use the service manual sequence to avoid damaging synchronizers and gears.
- Actions: on a bench, remove gearbox cover/case halves per manual, keep fasteners labeled; remove selector forks/shafts as needed, then remove any snap rings or retaining plates that hold the input shaft assembly.

6) Extract the input shaft
- Theory: the shaft must be free of gears/synchronizers that prevent bearing removal. Removing the shaft lets you inspect shaft journals and mating surfaces for wear that can spoil a new bearing.
- Actions: slide shaft out carefully; note orientation and order of spacers, washers, and gears.

7) Remove the old bearing
- Theory: bearings are press-fit; correct removal prevents housing or shaft damage. Heat/cold differentials can aid removal without overstressing parts.
- Actions: use bearing puller or press, or use controlled heating of the case (not the bearing) and cold of the bearing if necessary. Avoid hammering on the inner race (that would damage the shaft).

8) Inspect mating parts
- Theory: a new bearing on a damaged journal or housing will fail quickly. Check shaft journal roundness, keyways, splines, gear faces, bearing seat, and snap ring grooves.
- Actions: measure journals with micrometer, check runout, inspect case bore for scoring, replace shaft or machine surfaces if out of spec. Replace associated seals, circlips, and pilot bushing proactively.

9) Prepare and install the new bearing
- Theory: bearings must be installed to the proper interference fit and orientation so preload/endfloat and alignment are correct. Cleanliness and lubrication per spec are critical.
- Actions: clean housing and shaft, lightly oil splines but do not pack bearing with grease unless specified, press the bearing onto the shaft or into the case using a press or driver that contacts the correct race (press on outer race when installing into bore; press on inner race when installing onto shaft if the race fits the shaft). Heat the housing (e.g., 80–120 °C) to ease installation or cool the bearing if available. Fit new circlips/seals as required.

10) Reassemble input shaft assembly and check endfloat/preload
- Theory: correct axial clearance (endfloat) and bearing preload restore proper gear mesh and prevent bearing or gear damage. Measuring and adjusting shims or spacers is how you set this.
- Actions: reinsert shaft with all gears/spacers exactly as removed, install retaining plates/snap rings, measure input shaft axial play with a dial indicator; adjust shim(s) or spacer stack to achieve manufacturer spec. If bearings are angular-contact or preloaded, set preload per manual (torque and/or nut turns with lock method).

11) Reassemble gearbox, replace seals and gaskets
- Theory: restoring the gearbox to a sealed, lubricated state prevents contamination and ensures proper lubrication of the new bearing.
- Actions: fit new case gasket/sealant as specified, torque case bolts, replace front/rear seals, fit cover.

12) Reinstall transmission to engine and reassemble driveline
- Theory: proper alignment of clutch and input shaft prevents misloads on the new bearing.
- Actions: align clutch disc with alignment tool, mate gearbox to engine without forcing, torque bellhousing and clutch bolts to spec, reconnect driveshaft, linkage, and hydraulic lines.

13) Fill with correct gearbox oil and run initial checks
- Theory: correct lubricant specification and level ensure bearing life and proper gear cushioning.
- Actions: fill to correct level, run engine and shift through gears with vehicle stationary to feel engagement, check for abnormal noise, then road-test. Recheck for leaks and final torque recheck after a short run.

How the repair fixes the fault — theory summary
- Replacing the input-shaft bearing restores accurate radial support and concentricity of the input shaft. That
- reduces shaft runout and endplay,
- restores correct gear mesh geometry so gears and synchros engage smoothly,
- removes a noisy, frictional rolling element, eliminating whining/rumbling,
- removes a source of metal debris and contamination inside the gearbox,
- prevents accelerated wear of adjacent gears, shafts, and synchronizers.
- Proper fit, shim/preload and seal replacement are essential: a correctly installed bearing without correct axial clearance or on a damaged shaft will not resolve the root cause and will fail prematurely.

Final checks (concise)
- Inspect gearbox oil for metal debris after first few hundred km.
- Re-measure input-shaft endfloat and listen for bearing noise at varying engine RPM with clutch engaged and disengaged.
- If noise/roughness persists, inspect shaft journals and gear faces — replacing bearing alone fixes the support but not a damaged shaft or misaligned clutch.

Use factory service manual values and procedures for torque, shim sizes, bearing types and endfloat specs.
