Toyota 5S-FE engine factory workshop and repair manual download

Short version up front: most 5S‑FE cars use a hydraulic clutch (no routine cable adjustment). If yours has a cable, adjust the cable slack at the firewall. For hydraulic systems you “adjust” by setting pedal free‑play (clevis/pushrod if adjustable) and by bleeding/repairing the hydraulic system or replacing worn clutch parts — there’s no normal cable‑style turnbuckle adjustment. Below is everything you need to know, step‑by‑step, in beginner‑friendly language with clear checks, tools, and troubleshooting.

Why a clutch adjustment/repair is needed (theory, in simple terms)
- Purpose: The clutch transmits engine torque to the transmission by squeezing a friction disc (clutch disc) between the flywheel and a pressure plate. When you push the pedal the clamp is released so gears can be changed.
- What “adjustment” controls: the amount of pedal travel before the clutch actually begins to release (pedal free‑play) and/or the amount the release mechanism moves. Correct free‑play makes sure the pressure plate is fully engaged when released (no slip) and fully disengaged when pressed (no grinding).
- Analogies: think of the clutch as a spring clamp holding two slices of bread (flywheel + pressure plate) with a thin cheese slice (clutch disc) between. The diaphragm spring is the clamp. The release bearing is the finger that pushes the clamp open. Free‑play = how far your finger must move before it touches and starts to open the clamp.
- Why it fails/needs attention: slack or air in a hydraulic line, worn clutch disc or pressure plate, leaking master/slave cylinder, or incorrect pushrod/pedal adjustment. Symptoms: clutch slips under load (engine revs up, car doesn’t accelerate), clutch drags (gear clash, creep), or spongy pedal/poor engagement.

Main components (what every part is and what it does)
- Clutch pedal and pivot: you push this; changes lever motion into pushrod travel.
- Pushrod/clevis (between pedal and master cylinder): transfers pedal movement to master cylinder; some cars have adjustable clevis.
- Master cylinder (hydraulic): converts pedal push to hydraulic pressure; has reservoir for brake/clutch fluid.
- Rubber reservoir and hose: holds fluid (usually DOT 3/4 depending on model — check your manual).
- Hydraulic line (steel braided/ rubber): carries fluid to slave cylinder.
- Slave cylinder (external or concentric internal): receives hydraulic pressure and pushes the release fork or hydraulic throw‑out bearing.
- Release fork (if external slave): lever that moves the throw‑out bearing.
- Throw‑out (release) bearing: slides on transmission input shaft to press diaphragm spring.
- Diaphragm spring (on pressure plate): the ring that clamps the clutch disc to flywheel; pushing center releases clamp.
- Clutch disc (friction plate): friction material that carries torque from flywheel to transmission shaft.
- Flywheel: attaches to engine crank and gives a flat surface for the clutch disc.
- Transmission input shaft & pilot bearing: input shaft slides into clutch disc hub and pilot bearing keeps the shaft centered.

Two common system types and how adjustment differs
1) Cable clutch (older cars / some Celica models)
- Has a physical cable with an adjuster (usually at firewall or inline adjuster).
- You adjust slack by turning the adjuster/locknut until desired pedal free‑play is achieved.
2) Hydraulic clutch (most 5S‑FE installations)
- No continuous manual cable adjuster. System is supposed to be self‑adjusting.
- Adjust by setting pedal free‑play via adjustable clevis (if present) and by bleeding hydraulic system or replacing faulty components. If hydraulic and pedal position is wrong and pushrod has no adjustment, the fix is usually: bleed air, change master/slave cylinder, or replace clutch parts.

Tools & supplies
- Metric wrench & socket set (8–19 mm common)
- Pliers, screwdriver, rags
- Small ruler or Vernier caliper to measure pedal free‑play (mm)
- Brake fluid (correct DOT spec — check vehicle manual)
- Clear hose and catch bottle for bleeding
- Jack + stands (if you need to get under car) or ramps
- Protective gloves, eye protection
- Torque wrench for any fasteners you remove (if you disassemble)
- WD‑40 or penetrating oil for stuck locknuts
- Optional: vacuum bleeder or pressure bleeder for easier hydraulic bleeding

Safety first
- Work on level ground, park in gear/parking brake when jacked.
- Support car with jack stands if you go under it.
- Brake/clutch fluid damages paint — wipe spills immediately.
- Wear eye protection and gloves.

How to measure proper pedal free‑play (what to aim for)
- Typical target range for many Toyotas: about 10–20 mm (0.4–0.8 in) of pedal travel at the top of the pedal before you start to feel firm resistance. Exact spec varies by model/year — use factory manual if available.
- Method: sit in driver seat, measure distance from top of pedal pad to a fixed reference (or mark the pedal pad with tape), slowly press until initial resistance is felt (when the clutch begins to disengage) and measure the distance traveled. That is your free‑play.

Procedure A — If your 5S‑FE has a cable clutch (cable adjust)
1. Locate the cable adjuster:
- Usually at the firewall where the clutch cable passes into the engine bay or on an inline adjuster near the transmission.
- There will be a locknut and an adjustable barrel/nut.
2. Measure current free‑play (10–20 mm target).
3. Loosen locknut, turn adjuster:
- Turning the adjuster to shorten the cable reduces pedal free‑play (closer engagement), lengthening increases play.
- Make small turns, remeasure pedal free‑play.
4. Set to spec (start conservative ~12–15 mm).
5. Tighten locknut while holding adjuster in place.
6. Test: With engine off, press clutch and shift through gears to feel disengagement. Start engine, check smooth engagement, check for slipping or dragging. Readjust if needed.

Common cable clutch gotchas:
- Don’t over‑tighten — if there’s no free‑play the diaphragm spring could be partially released and clutch will drag and the release bearing will wear.
- A misadjusted cable causes gear crunching or clutch slip.
- Check cable condition: fraying, binding, or corroded ends mean replace cable rather than adjust.

Procedure B — If your 5S‑FE has a hydraulic clutch (most likely)
Important concept: hydraulic systems have no routine “turn the cable” adjustment. You adjust pedal feel/position by bleeding air and, if available, by adjusting the clevis/eye on the master cylinder pushrod or pedal pivot.

1. Preliminary checks
- Check the clutch fluid reservoir level. If low, inspect for leaks (master cylinder by pedal, slave cylinder at transmission, hose).
- Check pedal for free movement and no broken return spring or bent pedal.
- If fluid is dirty or contaminated, replace fluid in system by proper bleeding.

2. Measure pedal free‑play (target 10–20 mm). If it’s way off (very low or very high), note symptoms:
- Low pedal free‑play (engages too early / drags) — could be incorrect pushrod length/clevis setting, stuck slave, or internal master/slave leak.
- High pedal free‑play / pedal goes to floor — check for air in system, leaking master/slave, or worn clutch.

3. Bleeding air (two‑person method):
- Top up reservoir with clean fluid.
- Have an assistant slowly press pedal to floor and hold.
- Open slave bleeder nipple a 1/4 turn so fluid/some air comes out into a clear hose into a bottle. Close bleeder.
- Instruct assistant to release pedal. Repeat until clear fluid with no air bubbles, and pedal becomes firm.
- Keep reservoir topped to avoid sucking air back in.
- If you have a vacuum or pressure bleeder, use that per tool instructions (easier, fewer helpers).
- After bleeding, measure pedal free‑play/height again.

4. Pushrod/clevis adjustment (if adjustable):
- Many Toyotas have a clevis pin with split pin and nut at master cylinder pushrod or at pedal end. If adjustable, back out locknut, turn clevis to alter pedal free‑play: turning the pushrod in shortens effective length -> pedal engages sooner (reduces free‑play); out lengthens -> more free‑play.
- Make small changes and recheck pedal free‑play and operation.
- Tighten locknut and secure cotter pin.

5. If bleeding and pushrod adjustment don’t fix it:
- Inspect for leaks at master/slave. Replace leaking cylinder(s).
- If pedal is firm but clutch slips under load, likely worn clutch components (disc, pressure plate, or glazed flywheel) — removal and replacement required.
- If pedal is very low and no pressure after bleeding, master cylinder internal seal failure or slave cylinder failure is likely — replace component.

Common hydraulic system pitfalls
- Leaving reservoir low during bleed sucks in air and you’ll never get a firm pedal.
- Using the wrong fluid contaminates seals (check manual: some Toyotas use DOT 3 or DOT 4).
- Not checking for leaks at hose fittings and slave/master connections.
- Mistaking worn clutch for hydraulic issue or vice versa — if clutch slips even with a firm pedal, it’s usually worn disc/pressure plate.

How to diagnose what’s wrong before major teardown
- Pedal goes to floor and stays soft: air in system or failed master/slave.
- Pedal firm but clutch slips: worn clutch disc or weak pressure plate or oil contamination on disc (from leaking rear main seal or transmission input shaft seal).
- Clutch grabs very close to top of pedal (little free‑play): cable too tight or hydraulic pushrod over‑adjusted -> clutch dragging -> heat/wear.
- Clicking/rumbling when pressed: bad release bearing or bent fork.
- Fluid loss in reservoir: leak in lines, master, or slave. Inspect undercarriage around transmission for wetness.

If the clutch must be removed (overview of components you’ll see and inspect)
- With transmission off you will see the clutch assembly bolted to the flywheel.
- Inspect clutch disc for thickness and friction lining condition, uneven glazing, contamination.
- Inspect pressure plate diaphragm spring for heat spots or uneven wear.
- Check throw‑out bearing for roughness or binding.
- Inspect pilot bearing in crankshaft for wear.
- Check flywheel surface for scoring or hot spots — resurface or replace if necessary.

Final adjustment/test procedure after adjustment or repair
1. With engine off: check pedal free‑play and operation through full travel (no binding).
2. Start engine, depress clutch, select first gear and release clutch slowly — check for smooth engagement, no slipping, no noise.
3. Test drive: accelerate under moderate load, verify no slip and clean gear changes.
4. Recheck fluid level and inspect for leaks after test drive.

What can go wrong if you get it wrong
- Too little pedal free‑play: clutch never fully engages -> constant partial slipping -> overheating, quick clutch/pressure plate failure, burned friction material, high fuel consumption.
- Too much free‑play: clutch may not disengage fully -> gear grinding while shifting, transmission input damage, difficulty engaging gears.
- Improper bleeding: air in system -> spongy pedal, incomplete disengagement, inability to shift.
- Over‑tightening cable/clevis: release bearing is continually loaded -> premature bearing and diaphragm spring failure.
- Contaminating clutch with fluid (brake/clutch fluid or oil) -> clutch slips even if hydraulics perfect. Replace clutch if contaminated.

Quick troubleshooting checklist (beginner friendly)
- Check reservoir level & look for leaks first.
- Measure pedal free‑play (10–20 mm target).
- Bleed system if pedal is spongy or goes to floor.
- Inspect master/slave for leaks and replace if needed.
- If pedal is firm but clutch slips, assume worn clutch: remove trans and inspect/replace clutch kit + resurface flywheel if necessary.
- If unsure whether cable or hydraulic, look in engine bay for a clutch fluid reservoir (hydraulic). If there’s a cable going to a lever on the transmission, it’s cable.

Closing practical tips
- Always keep a small spare bottle of correct DOT fluid and a rag handy.
- If you have to remove the transmission to replace clutch, replace the throw‑out bearing and pilot bearing while you’re in there — they’re cheap insurance.
- Take note of pedal feel before you start working — it helps identify the problem after you finish.
- When in doubt about exact free‑play or fluid spec, refer to the factory service manual for your exact year/model 5S‑FE application.

That’s the full beginner mechanic’s guide: components, theory, tools, precise steps for cable and hydraulic systems, bleeding and adjustment technique, what goes wrong, and how to test. Follow the safety notes and measure pedal travel carefully — correct free‑play is the key to a long‑lived clutch.
