VMC - 50-Taper - Gearbox - 16DP-C - Oil Reservoir Refill - 500-ml Fill Tank - Introduction

This procedure tells you how to add oil to the 16DP-C gearbox on a 50-taper VMC.Do this procedure only on machines that have these parts:
  • 16DP-C gearbox
  • a 500-ml fill tank

The 500-ml fill tank is at these locations:

  • The fill tank [2] for machines with the Combined Air/Lubrication Module (CALM) is at the top of the spindle head cover
  • The fill tank [4] for other machines is attached to the sump tank.

 

caution: If the machine has the fill tank [2,4], do not put oil in the sump tank [1,3]. Refer to VMC - 50-Taper - Gearbox - 16DP-C - Oil Reservoir Refill Without 500ml Fill Tank.

Prerequisites

note: The gearbox 3-liter sump tank is filled at the factory with the correct amount of Mobil SHC 627.

When the mill operates correctly, the oil reservoir is empty. DO NOT fill the sump tank or the reservoir as part of standard maintenance.

Do this procedure when one of these alarms show:

 

Model Software Alarm
CALM 18.09A or higher 2011 SPINDLE GEARBOX OIL LEVEL IS LOW
2012 INSUFFICIENT SPINDLE GEARBOX OIL FLOW
Non-CALM Lower than 18.09A 179 LOW GEARBOX OIL PRESSURE

 

Tools Required

Mobil SHC - 627

VMC - 50-Taper - Gearbox - 16DP-C - Oil Reservoir - 500 ml Fill Tank - Refill

Step 1

Push POWER OFF.

Set the main circuit breaker to the OFF position.

Lock the main circuit breaker. Use an approved lock with an approved safety tag.

Step 2

If the machine has a CALM system, go to Step 3.

If the machine does not have a CALM system, do these steps:

  • Remove the head covers.
  • Remove the cap from the fill tank.
  • Add 17 oz (500 ml) of Mobil SHC 627 transmission oil to the 500 ml fill tank. Put the cap onto the fill tank.
  • Go to Step 4.

Step 3

For machines with the CALM system, remove the cap from the fill tank.

Add 17 oz (500 ml) of Mobil SHC 627 transmission oil to the 500 ml fill tank. Put the cap onto the fill tank.

Step 4

Push POWER ON.

Run this program:

M03 S1000;

G04 P60.;

M30;

This program operates the spindle and the gearbox oil pump for one minute. Do this to read the oil level correctly.

If the GEARBOX OIL alarms continue, do Step 5.

Step 5

Do these steps only if the GEARBOX OIL alarms do not stop after you push RESET:

  • Push POWER OFF.
  • Set the main circuit breaker to the OFF position.
  • Lock the main circuit breaker. Use an approved lock with an approved safety tag.
  • If the machine has a CALM system, remove the head covers.
  • Remove the cap [1] from the 3-liter sump tank.
  • Use a steel scale to measure the distance from the top of the sump tank to the oil level [2]. The correct distance is 1.0" - 1.8" (25.4mm - 45.7 mm).
  • Put the cap [1] onto the 3-liter sump tank.

Step 6

If the distance is more than 2" (50.8 mm), examine the gearbox for leaks. Repair the leaks.

Remove the fill tank cap and add 17 oz (500 ml) of Mobil SHC 627 transmission oil to the 500-ml fill tank.

note: Add oil to the plastic 500-ml fill tank only. Add only 17 oz (500 ml) each time.

Step 7

Push POWER ON.
Operate this program:

M03 S1000;

G04 P60.;

M30;

Wait 5 minutes. Push POWER OFF.

Set the main circuit breaker to the OFF position.

Lock the main circuit breaker. Use an approved lock with an approved safety tag.

Do Step 5 again to measure the oil level.

Do this procedure again, until the oil level is 1.0-1.8" (25.4-45.7 mm) from the top of the 3-liter sump tank.

Conclusion

Make sure no blockages are in the oil line between the reservoir and the gearbox if you have these conditions:
  • The oil level in the 3-liter sump tank is correct.
  • The GEARBOX OIL alarms stay after you push RESET.

Be aware: Many service and repair procedures should be done only by authorized personnel. The service technicians at your Haas Factory Outlet (HFO) have the training, experience, and are certified to do these tasks safely and correctly. You should not do machine repair or service procedures unless you are qualified and knowledgeable about the processes.

Danger: Some service procedures can be dangerous or life-threatening. DO NOT attempt a procedure that you do not completely understand. Contact your Haas Factory Outlet (HFO) and schedule a service technician visit if you have any doubts about doing a procedure.
