Perkins 4.107 4.108 4.99 Diesel Engines factory workshop and repair manual |
- Safety first
- Wear safety glasses, gloves, and durable clothing.
- Work on a cool engine; hot coolant and metal will burn.
- Disconnect the negative battery cable to avoid accidental starts.
- Catch coolant, oil or fuel spills in a drain pan and dispose of fluids properly.
- Essential tools (basic kit most beginners have) — what each is and how to use it
- Metric socket set (3/8" drive ratchet and 8–19 mm sockets)
- Use to remove bolts and nuts. Fit the socket fully onto the fastener, pull with steady force. Use an extension to reach recessed bolts.
- 1/2" drive breaker bar
- Provides extra leverage for stubborn bolts. Fit a socket, brace the bar and apply smooth force; do not use cheater pipes on the breaker bar.
- Combination spanners (open and ring ends) in metric sizes
- Use where sockets can't reach. Place ring end fully on the nut and pull toward the long side of the spanner to avoid rounding the nut.
- Torque wrench (click-type, appropriate range for small engine bolts, e.g., 20–150 Nm)
- Required for final tightening of manifold bolts. Set to the specified torque, tighten smoothly until the wrench clicks. If unsure of exact spec, use the workshop manual; if manual unavailable, typical M8 head bolts are around 20–40 Nm but confirm.
- Flat and Phillips screwdrivers
- For hose clamps, small screws and prying off vacuum hoses.
- Pliers (slip-joint and needle-nose)
- For hose clips, pulling vacuum lines, and holding small parts.
- Hose clamp pliers or pliers with good grip
- Use to remove and reinstall spring-type hose clamps.
- Gasket scraper (plastic or thin metal) and razor blades
- Remove old gasket material from mating surfaces. Hold scraper at low angle and push; don’t gouge metal.
- Wire brush and soft-bristle brush
- Clean carbon and rust from surfaces and bolt threads.
- Penetrating oil (e.g., PB Blaster, WD-40 Specialist)
- Spray onto rusty or tight bolts, let soak for 10–20 minutes before attempting removal.
- Drain pan
- To catch coolant when you disconnect hoses.
- Shop rags and a spray solvent (degreaser or brake cleaner)
- Clean surfaces before installing new gasket.
- Flashlight or work lamp
- For visibility in the engine bay.
- Rubber mallet
- Light taps to free a stuck manifold without damaging it.
- Small magnetic pick-up tool
- Retrieve dropped bolts in tight spaces.
- Recommended extra or specialist tools (why they are required)
- Torque angle gauge (if the workshop manual specifies torque-plus-angle bolt tightening)
- Some engines require a torque then an angle; this tool measures angle precisely.
- Stud extractor or stud remover kit
- If manifold studs are seized or the studs break, a stud extractor helps remove them safely.
- Thread chaser or M8/M10 tap and die set
- To restore damaged threads in the head or on studs; necessary if threads are corroded.
- Vacuum/air hose labeling tape or numbered zip ties
- To mark and later reconnect vacuum and breather lines correctly.
- Engine support or hoist (only if manifold removal requires removing heavy components like turbo or intake plumbing)
- Helps to hold heavier parts or to remove a turbo if fitted. Most basic intake manifold jobs on these Perkins engines don’t require lifting the engine, but check your setup.
- New intake manifold gasket set (high-quality OEM or equivalent)
- Always use a new gasket; old gaskets will leak and cause performance/cooling issues.
- Preparatory steps (what to do before taking bolts off)
- Park on level ground, apply handbrake, chock wheels.
- Let engine cool fully.
- Label and photograph everything you disconnect (vacuum hoses, breather pipes, throttle linkages, heater hoses) so you can reassemble correctly.
- Drain enough coolant into a pan to drop the level below any hoses connected to the intake manifold (if the manifold carries coolant).
- Remove the air cleaner, intake hoses, and any piping that blocks access to the manifold.
- Remove heat shields or other obstructions.
- Removal procedure (high-level sequence for a beginner)
- Disconnect any electrical connectors, vacuum lines, throttle/linkage, and breather pipes attached to the manifold — tag them.
- Remove obstructing items: air intake, intercooler piping or turbo inlet if present, fuel lines only if they attach to the manifold (do not break fuel lines unnecessarily).
- Place drip pan under area and loosen coolant hoses that attach to the manifold; be ready for some coolant loss.
- Spray manifold-to-head bolts with penetrating oil and allow to soak.
- Loosen and remove manifold bolts/studs in a criss-cross sequence to relieve stress; take care to support the manifold as bolts are removed.
- Gently pry the manifold free using a gasket scraper or rubber mallet as needed — don’t pry against mating surfaces harshly.
- Lift the manifold out and set on a clean bench. If it’s heavy or awkward, get help.
- Inspection and cleaning (what to check and why)
- Inspect mating surfaces on the cylinder head and manifold for flatness, nicks or corrosion.
- Check manifold for cracks, carbon build-up, or coolant leaks at the ports.
- Inspect studs/bolts for threads damage, stretch (elongated), or corrosion.
- Clean old gasket material fully with a gasket scraper and solvent; make sure ports are clean and dry.
- Check coolant passages for corrosion and blockages; flush if needed.
- Parts that typically must be replaced and why
- Intake manifold gasket (always replace)
- Reason: compressed and damaged once removed; reusing causes air or coolant leaks and poor engine performance.
- Manifold-to-head bolts/studs and nuts (replace if damaged)
- Reason: corroded or stretched fasteners don’t hold torque and can fail; replacing is cheap insurance.
- EGR valve gasket, thermostat housing gasket, throttle body gasket (if present)
- Reason: all old gaskets are likely compromised when disturbed.
- Coolant hoses and hose clamps (replace if old or brittle)
- Reason: disturbed hoses can leak; hose failure after reassembly is messy and avoidable.
- Manifold itself (replace only if cracked or warped)
- Reason: a cracked manifold causes leaks or coolant loss; warp can prevent sealing even with a new gasket.
- Studs or tapped inserts (if threads are damaged)
- Reason: damaged threads will not hold torque; repair is required to avoid head damage.
- Reinstallation tips (how to put it back correctly)
- Ensure all surfaces are clean, dry and oil-free before fitting the new gasket.
- Fit new gasket(s) and position manifold carefully.
- Thread bolts by hand to avoid cross-threading.
- Tighten bolts in a criss-cross pattern gradually to seat the gasket evenly.
- Use the torque wrench and torque to the specification in the Perkins workshop manual; if only general guidance is available, use appropriate torque for the bolt size but verify with manual.
- Reconnect hoses, vacuum lines and linkages per your photos/labels.
- Refill coolant to the correct level, bleed cooling system per manual or by running engine to open thermostat and topping off.
- Start engine and check for leaks (air, coolant or exhaust at manifold flange), and re-torque bolts after warm-up if recommended by the manual.
- How to use key tools — quick practical tips
- Ratchet and sockets: use the largest socket that fits; extensions give reach; release bolt slowly once loosened so it doesn’t drop into engine bay.
- Breaker bar: stand with feet stable; use steady force, not jerks; if a bolt won’t move, apply penetrating oil and heat if safe.
- Torque wrench: set desired torque, tighten smoothly until you hear/feel a click; do final torque with clean, dry threads and new washers where required.
- Gasket scraper: hold close to blade angle and push; avoid gouging the metal. Use plastic scraper first if worried.
- Penetrating oil: apply, wait, tap the fastener lightly with a hammer, then try loosening.
- Thread chaser: run gently through threads with light oil; do not use excess force.
- Common problems and fixes
- Bolt breaks or studs seize
- Use penetrating oil, heat if appropriate, and stud extractor or drill and helicoil if needed; replace studs if corroded.
- Coolant leak after reassembly
- Re-check gasket surfaces for flatness, re-torque bolts, replace gasket with correct type if necessary.
- Vacuum leak / rough idle
- Check all vacuum hoses and intake boots; ensure gasket is sealed and manifold mating surface is clean.
- Cracked manifold found
- Replace manifold; welded repairs are sometimes possible but not recommended for reliability.
- Final checks and running-in
- After assembly, top-up coolant, reconnect battery, and start engine. Check for leaks and listen for air hissing or unusual noises.
- After a short run, let engine cool and re-check torque on manifold bolts if the manual recommends it.
- Dispose of old gasket, fluids and used rags responsibly.
- Quick parts list to buy before you start
- Intake manifold gasket (OEM or equivalent)
- Any EGR/thermostat/other related gaskets that will be disturbed
- Replacement bolts/studs/nuts if old ones are corroded or damaged
- New coolant hose(s) and clamps if they’re old
- Penetrating oil, solvent, shop rags
- Final note (brief)
- Expect the job to take several hours if you’re a beginner. Take photos, label parts and proceed deliberately. If you encounter seized studs, cracked manifolds, or damaged head threads, a machinist or experienced mechanic help may be required.
