3 LUBRICATION

3.1 Recommended lubricants

WARNING!

The DRP+ is delivered WITHOUT oil and has 2 independent lubrication circuits. Fill them

with oil before using the DRP+.

Any damage due to incorrect lubrication will void the warranty.

WARNING!

The rack and the output gears must be lubricated before running the DRP+.

We recommend using a synthetic PAO based oil with viscosity 150 Cst at 40°C to lubricate the DRP+

such as one of the followings (or an equivalent); for alternates, please consult us.

3.2 Oil filling: right-angle configuration (DRP+R & DRP+P)

DRP+ are delivered with sight glasses and breathers in a separate plastic bag. They must be installed in

the correct position described in the following procedure and sketches.

1. Place the sight glass in the correct position.

2. Remove the two input plugs of the DRP+R & DRP+P (on the upper face of the bevel box).

3. Fill the DRP+R & DRP+P slowly until the oil level reaches the middle of the sight glasses. Note that

the level on the sight glass may take some time to stabilize.

4. Re-install the oil input plugs.

5. Install the 2 breathers (one per circuit) on the upper face of the bevel boxes in the place of the red

original plugs. (Except external forced lubrication).

6. Run the unit until it reaches operating temperature. Stop the unit, check and adjust the level.

Note:

For DRP1+R & DRP1+P the breathers are not necessary.

WARNING!

An O-ring seal insures the leak tightness of the oil plugs. Tighten carefully the plugs in

order to avoid damaging the seal.

WARNING!

External forced lubrication: special procedure.

For each lubrication circuit:

1. Connect the external lubrication pipes and fill them with oil. The oil suction is located in the bottom

hole of the bevel box and the oil injection in the upper hole of the DPR+ housing.

2. Adjust the oil level to the middle of the sight glass while the pump is not running.

3. Run the pump and re-adjust the oil level to the middle of the sight glasses while the pump is running.

Notes:

The breathers are not necessary.

Oil must be filtered (< 50µm).

Internal pressure must not exceed 1 bar.
