7. Reinstall the reservoir tank, and secure the tank to
the tank mounting flange with six (6) .250” - 20 x
.500” long Hex. Head Cap Screws.
8. Refill the reservoir following the instructions provid-
ed under “Filling And Maintaining Lube Reservoir
Oil Level,” page D-2.
LUBE SYSTEM OIL FILTER
The recirculating oil lubrication system on Model 101
OBI/OBS Series presses is equipped with a 25 micron
filter on the lubrication unit. (See Figure 1D.) Replace
the filter with a new 25 micron filter of the same type
after every six (6) months or 1300 hours of operation.
NOTE: The filter element should also be changed
whenever oil is changed in the reservoir. If oil
is not prefiltered, several filter changes may be
required after an oil change.
To Replace The Lube Unit 25 Micron Oil Filter:
1. Stop the main drive motor and make certain the fly-
wheel has stopped turning completely. Attach a
WARNING sign to the press controls to warn other
personnel that the press is currently being serviced.
2. Place the POWER, OFF-ON-BAR Selector Switch
in the OFF position and remove the key (if applica-
ble) to lock the switch in the OFF position. Then lock
the disconnect switch in the OFF position.
3. Place a receptacle under the filter to catch oil left in
the supply line. Turn the filter housing counterclock-
wise (as viewed from bottom). Then slip the con-
taminated filter off the internal pipe stub.
4. Dispose of contaminated filter element and any oil
drained from the supply line in accordance with
local government waste disposal regulations.
5. Pour an approved lubricant meeting the specifica-
tions of Minster Lubricant No. 1 into the new filter to
a level which is approximately 1.00” (25.4 mm) from
the top of the filter.
6. Apply a light film of oil to the threads and sealing
surface of the new filter. Install the new filter and
tighten it securely by hand.
7. After new filter element is installed, restore electri-
cal power to the press and start the main drive
motor. Check for, and correct, any leaks relating to
the filter.
LUBE DISTRIBUTION & METERING
Metering Units
Metering blocks serve as both the distribution and
metering center of the system. The metering blocks
contain small pistons which reciprocate in predeter-
mined order to meter lubricant to the various bearings.
Each piston must complete its travel before the follow-
ing piston will start to move. In case of a plugged or
mashed line, the piston cannot move against the solid
head of oil and, consequently, none of the other pistons
will move. This results in a “no-flow” condition and the
flow switch will immediately stop the press. A detailed
description on troubleshooting the meter blocks is
included in this manual.
To Check the Metering Units:
1. Remove socket head test plugs “A,” (See Figure 4D)
closest to the outlet side of each section. If oil surges
from one test port, the fault is (probably) beyond the
outlet side of the section which spurted oil.
2. While test plugs are removed, check assembly by
operating oil pump and observing a free flow of oil
from test port in each section. No flow of oil (from
one test port) indicates a stuck piston in that partic-
ular section. If this happens, see Step 4.
3. Replace socket head test plugs one at a time and
operate the lube pump after plug is installed. At the
same time, observe the lube FAULT light. If lube
FAULT light turns ON after a plug is installed, the
outlet line in common with the test plug just
replaced is probably blocked. Remove the obstruc-
tion or replace the mashed tubing as necessary to
correct the condition.
