Bijur - Mechanical - Oil Pump - (1) Drip-Sight Glass - Installation Introduction
This procedure tells you how to do these tasks:
1. Install (1) drip-sight glass assembly.
2. Install the oil lubrication tube that goes to the spindle.
Do this procedure when you replace a spindle that has (1) lubrication port with spindle that has (1) lubrication ports. Do this
procedures for mills that have these components:
1. The machine has a Bijur mechanical oil pump assembly.
2. The oil pump assembly does not have a sight glass.
3. The air and lubrication panel is under the enclosure.
Prerequisites
Parts Required:
For vertical mills use: P/N 93-2191 OIL SIGHT GLASS KIT VMC, BIJUR PUMP
For horizontal mills use: P/N 93-2096 OIL SIGHT GLASS KIT, HMC, BIJUR PUMP
Spindle - Oil Lubrication Tube - Installation
This procedure tells you how to install an oil lubrication tube for spindles. Do this procedure when you replace a spindle that has
a (1) oil lubrication port with a spindle that has (1) oil lubrication ports.
STEP 1
Press [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.
Close the primary air valve. This stops the air supply to the machine.

STEP 2
This step shows a VMC.
Disconnect the spindle lubrication tube from the fitting on the spindle.
Install the new lubrication tube from the spindle to the drip-sight glass.
Use the old tube [1] as a "fish tape" to pull the new tube [2] through the
machine.
Note: The illustration shows a minimum lubrication oil pump. The
procedure for a Bijur mechanical oil pump is the same.
STEP 3
This step shows a HMC.
Disconnect the spindle lubrication tube from the fitting on the spindle.
Install the new lubrication tube from the spindle to the drip-sight glass.
Use the old tube [1] as a "fish tape" to pull the new tube [2] through the
machine.
Note: The illustration shows a minimum lubrication oil pump. The
procedure for a Bijur mechanical oil pump is the same.

STEP 1
Remove the (2) cable tray retaining screws.
Remove the cable tray.
Note: The air and lubrication lines are removed from the image
for clarity.

STEP 2
Disconnect all of the air and lubrication tubes from the main manifold
assembly.
Disconnect the cable for the spindle air solenoid from the connector
bracket.
This bracket is on the rear of the main manifold panel.
STEP 3
Remove the (2) screws from the front of the main regulator bracket.
Remove the main manifold assembly.
STEP 4
Turn the spindle air manifold counterclockwise.
Remove and discard the spindle air manifold assembly.

STEP 5
Install the sight glass assembly to the rear-facing port of the air-lubrication
manifold regulator.
Turn the sight glass assembly clockwise to tighten it.
Note: Tighten the sight glass so that it is in a vertical position
when you attach the manifold assembly to the support panel.
Install the air-lubrication manifold regulator to the air-lubrication support
panel.
STEP 6
Remove the tee fitting [1].
Install the 5-way manifold [2]. Use the (1) screw [3].
Connect the tube from the spindle oil pump [4] to the 5-way manifold.
Connect the axis lubrication tubes [5] to the 5-way manifold.
Connect the oil tube [6] from the 5-way manifold to the drip-sight glass
fitting [7].
For HMCs only: Connect the tube for spindle "purge" air [8].
Connect the cable for the spindle air solenoid at the connector bracket.
STEP 7
Remove the red plug from the drip-sight glass fitting [1].
Connect the oil lubrication tube [2] to the fitting [3] at the bottom of the
drip-sight glass assembly.
Note: Cut the tubes shorter if needed. Do this to make sure the
tubes are not crushed or kinked.

STEP 8
Fill the reservoir to the MAX fill line [1].
Note: To prevent build up of contamination, use Mobil SHC 625,
Mobil 1 5W-20, or Mobil 1 10W-30. Do not use Mobil Vactra #2.
When you use Vactra #2, contamination ("sludge") collects in the
reservoir. This causes the pump assembly to become clogged.
You must fill the reservoir tank to the MAX fill line [1] each time you fill
the tank. This makes sure the dip trough [2] is full of oil. This lubricates the
drive and worm gears [3] of the pump.
Attach the cable tray under the main manifold assembly with (2) retaining
screws.
Install the air/lube cover panel.
Conclusion
Attach the cable tray under the main manifold assembly with (2) retaining screws.
Install the air/lube cover panel.

STEP 1
Remove the plug on the top of the tee on the drip-sight glass assembly.

STEP 2
Make sure that the air to the spindle is off.
Pull up on the pump handle [1]. This manually operates the oil pump.
Operate the pump several times. Do this until you see oil come out of the
tee fitting [2] on the top of the drip-sight glass. This removes all of the air
from the new oil line.
Install the plug on the drip-sight glass assembly.
STEP 3
Manually operate the oil pump.
Watch for oil to drip from the tube inside the drip-sight glass.
Manually operate the oil pump until you count 10 or more drops of oil in
the drip-sight glass.
STEP 4
Re-connect all of the tubes and electrical cables.
Set the main circuit breaker to the ON position.
Turn the machine air supply on.
Press [POWER ON].
In [MDI] mode, command the spindle to run at a low speed, for example,
5 RPM.
Set the air regulator [1] at the drip-sight glass to 10 psi (0.7 bar) [2].

STEP 5
Count the number of oil drops that fall through the drip-sight glass during
a normal pump cycle.
6 -10 drops per cycle in the drip-sight glass is the correct flow rate.
If you count less than 6 drops do the Bijur Mechanical - Oil Pump Axis - Timed Pressure Test.
If you count more than 10 drops adjust the air regulator at the dripsight glass to 15 psi (1.0 bar).
The increase in pressure reduces the number of drops.
Increase the pressure until no more than 10 drops are
produced per pump cycle.
Do not exceed 20 psi (1.4 bar) at the drip-sight glass air
regulator.
STEP 6
When the plunger on the oil pump assembly drops, oil is pumped into the
top of the drip-sight glass.
The oil slowly drips out, one drop at a time.
Each drop is clearly visible. Each cycle produces (6-10) drops of oil per
drip-sight glass.
The oil falls into the stream of air [1] from the spindle air solenoid.
The oil droplets [2] are carried up the spindle air and oil tube to lubricate
the spindle bearings.
Conclusion
Do the Bijur - Mechanical - Oil Pump Motor and Filter - Replacement
