Dynapac CP 132 2000 Workshop Manual – The One That Tells You What the Pressures Actually Are

If you’re turning wrenches on a Dynapac CP 132 2000 Workshop Manual, you’ve got a pneumatic tire roller that needs exact pressures or you’re chasing leaks all day. I’ve seen guys guess at charge relief settings and blow a seal in ten minutes. This factory manual – not a third-party reprint – gives you the numbers that keep the machine working and keep you out of the emergency room. Sixteen pages, all hydraulic, all original OEM data from Dynapac.

Traction System Coverage: What This Manual Tells You

Page 6 of this workshop manual walks you through the traction system hydraulic circuit. You get the forward/reverse relief pressure – 45 MPa (6500 psi) above charge pressure – and the normal working range of 10-18 MPa (1400-2600 psi) depending on rolling resistance. That’s not a guess from some online forum. That’s factory spec. You also get the charge relief numbers: 2.0 MPa (290 psi) with lever in neutral, 1.8 MPa (260 psi) with lever stroked. If you’re setting pressures, you need those exact values.

Brake System Pressure Settings – Why the Factory Values Matter

The brake system section starts on page 13. One spec jumps out: release pressure at fully released condition is 1.5 MPa (200 psi). I’ve seen aftermarket books list 180 psi or skip it entirely. That 20 psi difference can leave the brake dragging, overheating the oil, and burning up a $2,000 pump. The manual also states normal working pressure for the brake circuit is 8-12 MPa (1100-1700 psi) depending on working conditions. Page 5 has the full pressure settings table – don’t touch a relief valve without checking it first.

Does This Manual Cover the Drain and Steering Systems?

Yes. Chapter for the drain system starts on page 10, steering system on page 11. Both include circuit diagrams with the graphic symbols defined on page 4. The steering system relief pressure is 14 MPa (2000 psi) measured in the excess end stroke. If you’re replacing hoses or rebuilding a steering valve, those symbols matter. The manual uses ISO-style fluid power symbols – you need to know which triangle means pump versus motor. Page 4 explains every one.

3 Things You Need to Know About this 16-Page Document

First, the hydraulic tank volume is 75 liters (19.8 gallons US), system volume is 100 liters (26.4 gallons). Second, all pressure specs are given in MPa, bar, and psi – there’s a conversion table on page 3. Third, the warning on page 5 says it clearly: do not change any pressure setting without following Dynapac specification. This is not a suggestion. That warning exists because a wrong setting can launch a hose or lock the brakes at speed.

Source Authenticity: OEM vs Aftermarket Manuals

I’ll tell you straight – I’ve seen enough reprinted manuals that blur the diagrams and round the numbers to pay a few bucks less. This one is direct from the original Svedala Dynapac print, published September 2000. It applies from CA 132 PIN (S/N) *21620331* and up. The hydraulic circuit diagrams are crisp. The pressure table is original. If you’re a pro mechanic billing by the hour, you don’t have time to question whether 14 MPa is really 2000 psi or 2030. This manual answers it. Pair it with the Dynapac CP 132 Service Manual for component overhaul procedures, or grab the Dynapac CP 132 Parts Catalog if you’re ordering replacements. For older drivetrain work, the Manual Transmission reference might help if your roller uses a gearbox, though this CP 132 is all hydrostatic. Also check the DYNAPAC CP 132 Spare Parts Catalog for part numbers.

Frequently Asked Questions

Where do I find the charge pressure for the traction system?

Page 5.

How many pages is this manual?

16 pages. It covers only the four hydraulic systems – no engine or electrical.

Can I use this manual to troubleshoot a brake system that won’t release?

Yes. The brake system section on page 13 shows the release pressure spec at 1.5 MPa (200 psi). If your pressure at full stroke is below that, start checking the brake valve spool or the hydraulic lines. The manual also includes the circuit diagram with the directional control valve symbols. You’ll need a pressure gauge tee’d into the brake line to confirm. Don’t start pulling the brake housing until you measure pressure – I’ve seen guys replace brake discs only to find a stuck relief valve. That’s a wasted day. The manual gives you the test points and the expected numbers. Use them. And remember the hydraulic system volume is 100 liters – you’ll need that for refill after repairs.

Is this the same manual a Dynapac dealer would use?

It’s the factory workshop manual. Same W1063EN2 document the dealer techs get. No aftermarket edits.

Bottom line: if you’re working on a CP 132 pneumatic tire roller and you need the correct pressure settings, circuit diagrams, and fluid capacities, you need the OEM data. Manual Transmission knowledge won’t help you here – this is hydraulic-specific. Don’t waste time on generic write-ups. Access the Factory Manual and get the job done right.
