Dynapac CA 15 Technical Manual – Factory Maintenance Specs

You’ve got a Dynapac CA 15 vibratory roller on the job, and the lube chart is missing or the service intervals are a guessing game. I’ve seen guys dump the wrong grease into a hub and cook a bearing inside 50 hours. That’s expensive. This Technical Manual puts the OEM factory data back in your hands – 54 pages of what Dynapac actually prints for their own techs. No aftermarket fluff, no speculation.

Lubricants: Why Spec Matters

Page 1 lists the exact greases and oils – Shell Alvania EP Grease 2 for the bearings, SAE 10W/30 engine oil (API CD/SE), Shell Tellus T 68 for the hydraulics. You deviate from those NLGI No. 2 specs and you’ll have heat buildup that chews up parts. The manual even gives viscosity charts for air temperature ranges -20°C to +20°C. That’s the kind of detail you don’t get from a generic online list.

Maintenance Schedule – 54 Pages of Factory Intervals

The schedule on page 2 breaks it down by hours and days. Daily checks include hydraulic oil sight glass, wheel nuts, tyre pressures. Weekly gets into the drum oil sight glass and scraper inspection. If you skip the 14-day breather filter service, your hydraulic tank can draw contamination. Every three months you drain the hydraulic oil tank and replace the filter. That’s not a suggestion – it’s a timing spec.

Running-in instructions on page 3 are critical. First 50 hours – operate gently to let bearing surfaces harden. Ignore that and you lose service life. The manual calls out torque values for the hub (only on D and PD models) and wheel nuts. I’d trust those numbers because they came from Dynapac’s own heavy equipment division in Karlskrona, Sweden.

Special Instructions on Page 27 – Don’t Overlook

Page 27 covers special instructions. That section includes notes on cold-weather operation, supplementary lubrication recommendations if the roller works in extreme heat or cold. You call Dynapac for those if you’re outside the normal range. The manual tells you that. I’ve seen guys ignore the shock absorber mounting screw torque and end up with a broken articulation joint. The manual has those numbers.

Source Validity: OEM Print, Not Aftermarket Copy

This is a direct scan of the original Dynapac publication (part number M1-10216-1 ENG). The copyright page says “We reserve the right to change specifications without notice” – that’s how OEM docs work. Aftermarket manuals often guess at grease types or skip the hydraulic oil change intervals. This one gives you the exact Shell Tellus T 68 spec. If you need the parts breakdown, grab the Dynapac CA 15 Spare Parts Catalog”>Dynapac CA 15 Spare Parts Catalog alongside this. For operation and safety procedures, the DYNAPAC CA 15 Vibratory Roller Operation Manual”>DYNAPAC CA 15 Vibratory Roller Operation Manual is a good companion. And if you run other Dynapac gear like the CG233HF, the Dynapac CG233HF Instruction Manual”>Dynapac CG233HF Instruction Manual covers similar ground.

Don’t confuse this with a repair manual that shows you how to rebuild a Manual Transmission”>Manual Transmission. This is a maintenance technical manual – lubrication, adjustments, inspections, and special instructions. If you need transmission tear-down, find a dedicated service manual. For a refresher on Manual Transmission”>Manual Transmission fundamentals, that’s a separate subject.

Who Needs This Manual

Home garage guys who bought a used CA 15 and want to change fluids without guessing. Small rental fleets that need to document compliance. Mechanics who hate calling the dealer for a lube spec. The manual is short – 54 pages – but dense. Every page has a purpose. You won’t find a chapter on engine overhaul; this is about keeping the machine running between servicings.

I’ve been turning wrenches for 28 years. The fastest way to screw up a roller is to ignore the maintenance schedule. This manual hands you the schedule, the lubes, and the torque values. Use it.

Does the Dynapac CA 15 Technical Manual include torque specs for the wheel nuts?

Yes. Page 2 lists torque values for the wheel nuts as part of the maintenance schedule. The spec is directly from Dynapac’s factory documentation.

What lubricants are specified for the hydraulic system?

The manual calls for Shell Tellus Oil T 68 (anti-wear additive) on page 1. For cold conditions, you may need a different viscosity – the manual includes a chart for air temperature ranges. If temperatures drop below -20°C or go above +40°C, you are directed to contact Dynapac for supplementary recommendations. That’s OEM thoroughness, not guesswork.
