How to Use This Catalog

• Stay 14L-focused: Parts and guidance here are tailored to the Series 60 14.0L engine and its common highway/industrial configurations.
  
  

• Match by engine data: Confirm fitment with your engine serial number (ESN) and build data. Different production years and emissions packages can change small details (e.g., thrust interfaces, seals, and roller kits).
  
  

• Replace in systems: A worn cam bearing often coincides with wear on thrust seals and idler-gear bearings. Grouping replacements minimizes downtime and prevents rework.
  
  

• Mind best practices: Clean mating surfaces, inspect gear lash and thrust endplay, and use fresh seals whenever a cover is removed.
  
  

Gasket for the Accessory Drive Cover

Catalog item: Detroit Diesel Gasket for the Accessory Drive Cover

What It Does

The accessory drive cover protects the gear train and supports the accessory drive interface. This gasket seals the cover to the front housing, keeping engine oil inside while the cam gear, idler gears, and accessory drive gears do their work.

When to Replace

• Oil seepage or drips forming at the cover perimeter.
  
  

• Recent front cover work: Any time the accessory drive cover is removed, best practice is to install a fresh gasket.
  
  

• Contamination events: If the engine ingested debris or had a coolant/oil intermix event, renew all disturbed gaskets during cleanup.
  
  

Installation Tips

• Clean both surfaces to bare metal—no old sealant, no fibers.
  
  

• Dry-fit the cover to confirm alignment pins and dowels seat cleanly.
  
  

• If a light film sealant is specified by your manual, apply a thin, even coat and avoid excessive material that can squeeze into oil passages.
  
  

• Re-check accessory drive alignment and gear backlash specs after assembly.
  
  

Camshaft Bearing (Series 60)

Catalog item: Cam Bearing for Detroit Diesel Series 60

Role in the Valve Train

Camshaft bearings support the cam journals, maintain precise oiling, and stabilize rotational accuracy so injector and valve events happen exactly when the ECM expects them. On a 14L working under sustained load, bearing health is critical for consistent timing and quiet valvetrain operation.

Symptoms of Bearing Wear

• Knock or rumble localized near the cam tunnel at hot idle.
  
  

• Oil pressure fluctuations with no pump or sensor fault.
  
  

• Erratic injector timing behavior after eliminating harness/sensor causes.
  
  

• Excess metal in oil analysis (bearing overlay/tin/lead flags).
  
  

Service Guidance

• Inspect the camshaft journals for scoring, out-of-round, or taper; correct cam issues before installing new bearings.
  
  

• Verify oil feed passages are clear. Any varnish or sludge in the cam gallery deserves a thorough cleaning.
  
  

• Use the correct mandrels/sleeves and press squarely to avoid misalignment.
  
  

• After installation, measure cam endplay and journal clearance per manual—bearing wear is often a symptom of oil starvation or misalignment upstream.
  
  

Roller & Pin Kit for Rocker Arm — Injector & Exhaust Valve Arm (Twelve per Engine)

Catalog item: Detroit Diesel Roller and Pin Kit for Rocker Arm — Injector & Exhaust Valve Arm (12 per engine)

Where It Fits

This roller and pin kit services the injector and exhaust rocker arms. The roller provides a low-friction interface with the cam lobe, while the pin acts as the pivot axis. On the Series 60 14L, the injector and exhaust arms see high cyclic loads—healthy rollers keep tracking precise and prevent lobe scuffing.

Common Wear Indicators

• Ticking or chirp at a steady cadence tied to engine speed.
  
  

• Flattened or pitted roller surface, causing accelerated cam lobe wear.
  
  

• Side play at the rocker pivot, signaling pin wear.
  
  

• Uneven injector calibration or smoke if injector actuation is compromised.
  
  

Best Practices

• Replace in complete sets per bank to balance wear.
  
  

• After installing rollers and pins, re-set valve and injector lash to spec on a cold engine.
  
  

• Inspect rocker arm bores for ovality and the rocker shaft for wear tracks—rollers are often the visible failure, but pivot geometry matters just as much.
  
  

• Use proper lubrication on first start after service.
  
  

Roller & Pin Kit for Rocker Arm — Intake Valve Arm (Six per Engine)

Catalog item: Detroit Diesel Roller and Pin Kit for Rocker Arm — Intake Valve Arm (6 per engine)

Why It’s Separate

The intake rocker’s geometry and load path differ from the injector/exhaust arm. This intake-specific kit preserves accurate intake-valve lift and timing, crucial for breathing efficiency and EGR performance on many 14L setups.

What to Watch For

• Hollow tap or light rattle under light throttle.
  
  

• Misfire-like hesitation that disappears at higher RPM (subtle intake valve motion error).
  
  

• Cam lobe polish with micro-pitting from a roller that no longer spins freely.
  
  

Service Tips

• Replace all six intake rollers together for uniform wear.
  
  

• Inspect pushrods for straightness and tip wear whenever intake rockers are off.
  
  

• Confirm valve spring condition—weak springs accelerate roller distress.
  
  

Camshaft Thrust Seal

Catalog item: Detroit Diesel Seal, Camshaft Thrust

Purpose

The thrust seal helps contain oil at the camshaft thrust interface where axial loads are absorbed. On high-mileage 14L engines, axial control is vital: fuel timing relies on precise cam phasing relative to the crank and accessory drive.

Failure Clues

• Oil trace at the thrust plate area or behind the front cover.
  
  

• Noticeable endplay beyond spec during teardown checks.
  
  

• Noise at the front cover resembling a light grind under RPM changes (after excluding belt/pulley issues).
  
  

Replacement Notes

• Always check the thrust plate surface and cam nose for scoring.
  
  

• Verify that oil feed and drain paths around the thrust location are clear.
  
  

• After seal replacement, re-measure cam endplay and record it in your service log.
  
  

Seal for Camshaft Thrust Plate (Series 60)

Catalog item: Detroit Diesel Seal for Camshaft Thrust Plate — Series 60

What It Seals

This seal interfaces with the thrust plate itself, complementing the thrust seal above to keep oil where it belongs and to stabilize the cam’s axial location during load shifts (start-up, grade pulls, engine braking).

Good Practices

• Replace this seal whenever the thrust plate is removed.
  
  

• Inspect plate flatness and the seating surface on the front housing.
  
  

• Use proper torque sequence on the plate fasteners to avoid warping and leaks.
  
  

Woodruff Key for Camshaft

Catalog item: Detroit Diesel Key for Camshaft (Woodruff Key 1/4" x 3/4")

Why the Key Matters

This woodruff key positively locates the cam gear on the camshaft. Correct key fitment ensures the cam gear cannot slip on the shaft taper, preserving precise timing. A deformed, undersized, or reused key is a common root cause of “mystery” timing errors after a rebuild.

Technician Notes

• Always install a new key when replacing or refitting the cam gear.
  
  

• Inspect the keyseat in the camshaft and the gear hub for galling.
  
  

• Seat the gear fully and verify gear mesh and backlash before buttoning up the cover.
  
  

Bearing for the Idler Gear (Series 60)

Catalog item: Detroit Diesel Series 60 Bearing for the Idler Gear

Function in the Gear Train

The idler gear transmits motion between the crank gear, cam gear, and accessory drive. Its bearing carries radial loads at all operating speeds. On a 14L, this bearing’s health directly affects valvetrain timing stability and front-end noise.

Signs of Trouble

• Whine or growl from the gear case that grows with RPM.
  
  

• Metallic fuzz on magnetic drain plugs after front-gear work.
  
  

• Accelerated cam/thrust wear caused by irregular gear mesh.
  
  

Replacement & Setup

• Inspect the idler shaft and support bore. Replace the bearing as a matched solution; don’t press a new bearing into a damaged bore.
  
  

• Check gear backlash with the cam and crank gears after installation.
  
  

• Verify endplay and confirm oil feed to the bearing path is unobstructed.
  
  

Seal — Oil Accessory Drive

Catalog item: Detroit Diesel Seal, Oil Accessory Drive

What It Protects

This seal keeps engine oil inside the accessory drive interface while the gear train spins. Any leak here tends to mist the front of the engine, collect dust, and eventually make its way onto belts and pulleys—leading to secondary issues.

Replacement Checklist

• Inspect the shaft surface where the seal rides; polish or replace the component if grooved.
  
  

• Install the seal square and to depth, using the correct driver.
  
  

• Recheck pulley alignment and belt tension to avoid side-loading the new seal.
  
  

• After first run, wipe the area clean and monitor for weeping.
  
  

Planning a 14L Camshaft/Valvetrain Refresh

Prioritize by Symptoms

• Noise + timing codes: Start with roller kits, cam bearings, and idler bearing inspection.
  
  

• Oil leaks at the front: Accessory drive cover gasket, oil accessory drive seal, and thrust seals go to the top of the list.
  
  

• High mileage without records: Proactive replacement of rollers/pins and critical seals can prevent lobe scuffing and gear train distress.
  
  

Prevent Recurrence

• Stick to quality oil and filter intervals; varnish and debris shorten roller and bearing life.
  
  

• After any front-gear work, always verify backlash and endplay.
  
  

• Log measurements (lash, endplay, backlash) in a service notebook—these trends help you catch issues earlier next time.
  
  

Installation & Setup Essentials (General Guidance)

Always consult your service manual for torque values, lash settings, and special procedures.

• Cleanliness is king: Use lint-free wipes, keep grit out of the cam tunnel and front gear housing.
  
  

• Measure, don’t guess: Journal clearance, endplay, backlash, and lash should be checked and recorded.
  
  

• Lubricate on assembly: Use assembly lube on rollers, pins, cam lobes, and bearings to protect against dry starts.
  
  

• Rotate by hand: After reassembly, rotate the engine two full turns and re-check lash and any interference.
  
  

• Road test and re-inspect: After your first heat cycle and short road test, re-inspect for leaks and verify noise levels.
  
  

Troubleshooting Quick Reference

• Ticking at idle → Likely rocker roller wear (intake or injector/exhaust kits).
  
  

• Growl/whine at RPM → Investigate idler gear bearing and overall gear mesh.
  
  

• Oil mist at front cover → Accessory drive cover gasket and oil accessory drive seal.
  
  

• Erratic injector performance with no electrical fault → Cam bearing wear or roller tracking issues.
  
  

• Fresh timing drift after gear work → Check woodruff key seating and cam gear fit.
  
  

Related Components & Helpful Pairings

Even if you’re addressing a single leak or noise, it’s smart to bundle parts that share labor:

• Front cover service set: Accessory drive cover gasket + oil accessory drive seal + thrust plate seal(s).
  
  

• Top-end timing set: Cam bearings + both rocker roller/pin kits + woodruff key.
  
  

• Gear train stabilization: Idler gear bearing + thrust checks + fresh lubricant and careful backlash verification.
  
  

Bundling these parts in one service window frequently saves multiple teardowns and helps the 14L return to a quiet, predictable operating character.
