Oiler Assembly Maintenance and Safety Practices
The oiler assembly is illustrated in the figure entitled Oiler Assembly.
Not easily viewable from the referenced figure is the precise location of the oiler body (in relation to the
top and bottom covers) when mounted on the tubing. The oiler body has a groove in the OD of the plastic
housing that fits into the larger semi-circle cutouts in the top and bottom covers. This groove keeps the
oiler assembly oriented in the correct direction and locks it in place.
Each oiler assembly is sized to accommodate the two sizes of tubing potentially used with a particular
measuring head (within the constraints described in Tubing Sizes for Argus TubeSpec Model Numbers
).
The user adjusts the oiler assembly to conform to one of two possible tubing sizes specific to a measuring
head by switching part numbers 5 and 6 with part numbers 27 and 28.
Part numbers 3, 5, 6, 27, and 28 are all wear parts, so must be inspected after each job for serviceability:
• When the UHMW bearing (part numbers 6 and 28) is .25" over nominal tubing, it must be replaced.
Change the UHMW bearing by following the instructions in Step k. on page 42.
• If the sponge (part number 3) is packed with debris, clean it before the next use.
