Mitsubishi Delica L300 factory workshop and repair manual download

- Safety first
- Park on level ground, engine off, parking brake on, wheels chocked; disconnect battery negative if working near electrical or fuel components.
- Wear gloves and eye protection. If you need to raise the vehicle, use a proper jack and jack stands — never rely on the jack alone.

- What “accelerator linkage” means here
- On a Delica L300 this usually means the throttle cable from the pedal to the throttle body/carburetor plus the small linkage pieces, bushings and return spring at the throttle. The goal is to inspect, lubricate, adjust free play, or replace the cable/parts if they’re worn, frayed, sticking, or broken.

- Tools (detailed description and how to use each)
- Socket set with ratchet (metric sizes 8–14 mm typically)
- Description: ratchet handle and sockets that fit over hex nuts/bolts.
- How to use: select socket that fits snugly, attach to ratchet, turn clockwise to tighten, counterclockwise to loosen. Use extensions for hard-to-reach nuts.
- Combination wrenches (metric set 8–14 mm)
- Description: open end on one side, boxed end on the other.
- How to use: use boxed end for firm grip on nut, open end for tight spaces. Hold the bolt/nut steady while loosening the opposite fastener.
- Screwdrivers (Phillips and flat)
- Description: tip fits screw heads.
- How to use: choose correct size tip to avoid stripping; turn to loosen/tighten clamps or small screws.
- Needle-nose pliers
- Description: long-nosed pliers for gripping small parts/wire clips.
- How to use: squeeze to hold/pull small clips, connectors or cotter pins; good for removing spring clips on linkage.
- Adjustable (crescent) wrench
- Description: variable jaw opens to fit many bolt sizes.
- How to use: set jaws tight on fastener to avoid rounding; use when metric wrench not available.
- Slip-joint or locking pliers (vice grips)
- Description: extra strong grip for rounded or stubborn parts.
- How to use: clamp onto part, lock in place; useful for holding cable end while loosening nuts.
- Cable luber or thin-gun oil and a long straw applicator
- Description: tool or lubricant used to reduce cable friction.
- How to use: run lubricant into the cable sheath ends and housing while moving cable back and forth to distribute.
- Penetrating oil (WD-40, PB Blaster)
- Description: loosens rusted seized fasteners.
- How to use: spray on rusty nuts/bolts, wait 5–15 minutes, then attempt removal.
- Small pick set
- Description: pointed tools to pry out rubber bushings or remove cotter pins.
- How to use: gently pry clips/bushings without tearing them.
- Flashlight or work light
- Description: illuminates dark engine bay or pedal area.
- How to use: position light to see linkage ends and cable fittings.
- Clean rags and mild degreaser
- Description: for cleaning grime and old grease.
- How to use: wipe linkage and inspect condition.
- Optional but recommended: jack and jack stands
- Why required: for access to underside if cable routing or firewall fittings are easier from below.
- How to use: lift vehicle at manufacturer jacking points, place stands, lower jack off stands.

- Extra tools you might need and why
- New cable (replacement) — required if cable is frayed, stretched, inner wire broken, or sticking.
- Replacement end fittings, bushings or circlips — required if mounting hardware is worn or missing to ensure secure attachment and correct movement.
- Throttle return spring — required if original spring is weak or broken; necessary to ensure throttle returns to idle.
- Carburetor/throttle body linkage rebuild kit (if applicable) — required when pivot bushings or small linkage parts are worn.
- Torque wrench (optional) — used to tighten fasteners to proper torque if you want exact specs; not strictly required for beginners but useful.

- Signs parts must be replaced (what to look for)
- Frayed or broken inner cable wires — replace cable immediately (safety + drivability).
- Cable housing cracked or split — replace to prevent binding/water ingress.
- Excessive play at pedal (more than a few mm) or very tight pedal (binding) — cable stretching or attachment wear may require replacement or adjustment.
- Sticky or slow returning throttle — check and lubricate; if persists, return spring or cable likely bad.
- Corroded/rounded end fittings, missing clips or worn bushings — replace to restore precise movement.

- What replacement parts to buy (what to match)
- Throttle cable assembly for Mitsubishi Delica L300 (specify year/engine when ordering) — choose OEM or a high-quality aftermarket that matches length, end fittings (barrel or ball ends), and mounting style.
- End clips/cotter pins and rubber bushings — cheap parts to replace worn mounts.
- Throttle return spring (vehicle-specific strength) — match OEM style or appropriate aftermarket equivalent.
- Throttle body or carburetor linkage rebuild kit if pivot bushings or pins are worn.

- Quick overview procedure (step-by-step in bullets)
- Inspect visible cable from pedal to engine bay
- Look for fraying, rust, kinks, damaged sheath or loose attachments. Wiggle cable and see if it moves smoothly.
- Check pedal free play and return
- With engine off, press the pedal gently and note the small travel before throttle begins to move at the carb/throttle body. Typical acceptable free play is minimal — a few millimeters; the throttle should snap back quickly when released.
- Lubricate cable and linkage first (if not damaged)
- Apply penetrating oil or cable lube at both ends and along exposed sheath while operating pedal to draw lubricant through. Use a spray straw for precision.
- Adjust cable free play (if adjustable)
- Locate adjuster near throttle body or at firewall bracket — usually a locknut and threaded cable end.
- Loosen the locknut with two wrenches, turn adjuster to reduce free play until slight movement of pedal produces throttle movement, then retighten locknut.
- Ensure there is still a small free play so throttle is not held open at rest.
- Test throttle operation before driving
- With engine off, operate pedal full travel, check that throttle opens fully and returns without sticking. Check for binding through entire motion.
- Remove and replace cable if needed
- Disconnect cable at pedal end: remove retaining clip or remove pedal pad to access cable end; use needle-nose pliers or pick to remove clip.
- Follow cable up through the firewall; remove firewall grommet if necessary.
- In engine bay, unclip cable from throttle bracket, remove any mounting clips and nuts (use socket/wrench). You may need penetrating oil on rusty hardware.
- Pull cable out. Compare old cable length and end fittings with replacement.
- Install new cable by routing it the same path, ensure grommet sealed in firewall, attach at throttle body and pedal, secure clips and nuts.
- Adjust free play with adjuster, secure locknut, test pedal return.
- Replace small linkage parts if worn
- Remove worn bushings, clips, springs and replace with new ones from kit. Use needle-nose pliers and pick to remove/install.
- Ensure pivot pins move freely and are lubricated.

- Testing and final checks
- Start engine, observe idle and throttle response while someone slowly presses pedal (use care; keep engine bay clear).
- Check for smooth acceleration and immediate return to idle when released.
- Re-check adjuster locknut is tight and cable cannot slip.
- Road test gently; if throttle feels sticky, noisy, or does not return fast, stop and re-check installation and spring condition.

- Common beginner mistakes and how to avoid them
- Leaving cable too tight so throttle is slightly open at rest — always leave a small free play.
- Reusing seriously frayed cables — replace them; frayed cables can snap suddenly.
- Forgetting to secure grommets/clips — leads to wear and misrouting.
- Not testing return under engine run — a cable may look fine cold but stick when warm or when engine moves.

- Troubleshooting quick tips
- Pedal feels spongy or delayed: inspect cable for inner wire stretch or damage.
- Throttle hangs open: likely return spring broken or cable dragging — remove cable and check free movement.
- Excessive pedal free play after adjustment: either adjuster backed out or cable stretched — check fittings and replace cable if needed.

- Final notes (concise)
- If cable or fittings are damaged, replacement cable and new small fittings/spring are usually necessary and inexpensive compared to the risk of failure.
- When ordering parts, provide vehicle year, engine code and whether the vehicle has carburetor or throttle body injection to get the correct cable.
- Work methodically, keep removed small parts in a tray, and don’t rush tests.

- Safety reminder
- If you’re unsure about any step affecting engine throttle control, consider a mechanic — throttle failure can be dangerous.
