Filling
Table 13
Description
(1) Are the shop personnel using Wall Chart, RENR2059, "Disassembly and Assembly Procedures for Rollers with Inverted Duo-Cone Seals", Wall Chart, RENR3961, "Disassembly and Assembly Procedures for Rollers with Conventional Duo-Cone Seals", and Wall Chart, RENR3962, "Disassembly and Assembly Procedures for Snap Ring and Oval Track Rollers" for the oil fill volumes and procedures?
(2) Is the rubber stopper lubricated with a light-weight oil to promote expansion and installed with the proper stopper installer?
(3) Is the roller filled to 80% to 90% with SAE30 oil and the plastic plug installed?
(4) Is the oil filtered properly to prevent contamination?
(5) Do air bubbles exist in the stream of oil? Air bubbles can be caused by a worn out pump, low oil level, and broken pipes.
(6) Is there a loss of vacuum? Create a vacuum with finger over the lubricator tip, release the vacuum button, and check for loss of vacuum by viewing the gauge. (If loss of vacuum is observed, check all connections between the button (valve) and the tip.)
(7) Check the accuracy of gauges. Do the gauges zero? Are the gauges broken or have a broken glass? Replace any damaged gauges.
(8) Is the overall condition of the hoses and related equipment in good condition?
(9) Does the fill and vacuum button have an over center finger or palm pad to reduce fatigue?
(10) Is the regulator set at a maximum of 552 kPa (80.0 psi)? Pressure above 552 kPa (80.0 psi) will blow the seals.
(11) Electrical controls auto lubricator
(a) Is vacuum set at a minimum of 138 kPa (20.0 psi)?
(b) Is pressure set at a minimum of 379 kPa (55.0 psi)?
(c) Is partial vacuum set at zero?
(12) Is the roller shaft gently tapped with a hammer to ensure that the roller contains oil?
