DAF 22113 Training Manual – 24 Pages of Factory Clutch Knowledge

If you’re wrenching on a DAF truck and the clutch system has you second-guessing which line goes where, you’re not alone. I’ve watched guys burn a whole Saturday because they trusted a generic aftermarket write-up that skipped the master cylinder circuit or left out the servo relation. This DAF 22113 Training Manual is the real deal — 24 pages of factory training material that walks you through the clutch plate, clutch servo, and master cylinder without assuming you already know the system. No fluff, no guesswork — just the OEM logic DAF uses to train their own techs.

Page 1 and 2 cover the master cylinder and clutch servo identification. That alone saved a buddy of mine from replacing a good servo because he didn’t realize the master was half-stroked. Page 3 gets into the clutch and clutch plate assembly with DAF part numbers: 1310897 for the clutch unit and 1376143 for the plate. If you’re ordering parts, those numbers are gold.

Master Cylinder and Clutch Servo – Pages 1–2

These two pages are worth the price of the manual alone if you’ve ever stared at a clutch servo and wondered which port does what. The manual shows the DAF layout with OEM identification. It doesn’t stop at naming parts — it shows how the master cylinder feeds the servo and what happens when you push the pedal. If you’re dealing with a hard pedal or slow release, start here. Too many techs skip the master and go straight to the clutch plate, then scratch their heads when the new plate still shudders.

3 Transmission Types – How the Clutch Role Changes

Page 4 of the manual breaks down the clutch’s job depending on transmission type: manual, semi-automatic, and automatic. For manual transmissions, the clutch has two tasks — drive away AND engage gears. Semi-auto adds a torque converter for takeoff and shifting clutches for gear changes. Full auto? The clutch only handles driving away; gearchanging uses wet clutches inside the box. If you’re swapping transmission types or diagnosing a clutch that only slips when shifting, this section keeps you from misdiagnosing the root cause.

For a refresher on how manual transmissions engage, check the Wikipedia article on Manual Transmission. But this manual gives you the DAF-specific details that Wikipedia can’t.

Clutch Criteria: What DAF Demands from a Clutch Plate

Page 5 lists the criteria a clutch must meet for DAF trucks: gradual engagement, no slip under full load, good heat dissipation, small size, low weight, simple design, inexpensive production, and easy repair. That last one is something you appreciate when you’re lying under a truck. The manual explains how those criteria affect the choice of clutch plate material and assembly. If you’re replacing a clutch with a non-OEM plate that doesn’t match these specs, you’ll get chatter or premature wear. The manual gives you the factory reasoning so you can make informed choices.

24 Pages of Factory Training – No Aftermarket Shortcuts

This isn’t a reprint of some third-party summary. It’s a scanned OEM training manual, complete with the original diagrams and text. The DAF 22113 designation means this was used in actual DAF training programs. Every page, from the function summary on page 4 to the criteria list on page 5, is factory-sourced. I’ve compared aftermarket clutch guides to this — they miss the details about semi-automatic engagement that can cause you to replace a torque converter for no reason. Stick with the source.

Does This Manual Cover Semi-Automatic and Automatic Transmissions?

Yes. Page 4 explicitly describes the clutch’s role for all three transmission types. For semi-automatic, it explains that the torque converter handles driving away while shifting clutches inside the gearbox manage gear changes. For automatic, the manual clarifies that the only clutch job is enabling drive-away; all gearchanging is done by multiple-disk wet clutches inside the transmission. That distinction is critical when you’re chasing a no-move condition after a transmission swap. The manual won’t leave you guessing.

What is the total page count of this manual?

24 pages.

Does this manual include torque specifications for clutch bolts?

No, this is a training manual focused on system function and component identification. It does not contain repair-specific torque values or step-by-step replacement procedures.

What DAF part numbers are referenced?

DAF No. 1310897 for the clutch unit and DAF No. 1376143 for the clutch plate are listed on page 3.

How does this manual help me diagnose a clutch slipping issue?

It helps by teaching you the function and criteria of the clutch. The manual explains that the clutch must not slip when fully engaged even under heaviest load — that’s a key diagnostic checkpoint. It also covers the master cylinder and servo circuit (pages 1–2), so you can test hydraulic pressure before blaming the clutch plate. If you understand the system’s requirements (gradual engagement, no slip, heat dissipation), you can work through failures methodically. For example, a clutch that slips only during gear changes points to a problem with the manual transmission’s secondary task — the manual makes that distinction clear on page 4. This foundational knowledge prevents you from misdiagnosing a release bearing issue as a plate failure.

If you’re serious about DAF truck clutch work, start with the source that DAF themselves use. The DAF 22113 Training Manual gives you 24 pages of factory knowledge — no generic diagrams, no aftermarket guesses. Whether you’re a fleet mechanic or a home garage enthusiast, this manual will keep you from wasting time on wrong parts and wrong diagnoses. Access the Factory Manual and get the real training.
