Parts and Service Memo PSM 025 1310 JAW MSC SUBJECT: Jaw Crushers. Jaw Bearing Lubrication Intervals. As a followup to PSM 022 released November 2012, this bulletin is to remind users of KPI-JCI Legendary and Vanguard series jaw crushers of the lubrication requirements for jaw crusher bearings. Grease Selection Grease selection is critical when operating the Legendary and Vanguard series jaw crushers. Proper fl owability and oil viscosity is essential for jaw performance. Because of this, KPI- JCI recommends using Mobilith SHC 007, a synthetic NLGI 00 grease. Mobilith SHC 007 is recommended for all temeprature ranges. KPI-JCI also recommends Chevron Ultra Duty HD00, a mineral based grease, as a viable option and is recommended for ambient temperatures above 40 degrees F. Mobilith SHC-007 and Chevron Ultra-Duty HD00 are compatible and can be used together; however, mixing products may decrease performance. For maximum performance, thoroughly clean the system before adding a new lubricant. CAUTION Contact the factory if you are planning to use any grease other than Mobilith SHC 007 or Chevron Ultra-Duty HD00 for lubricating the outer main and pitman jaw bearings. Calibration KPI-JCI Legendary and Vanguard jaw crushers are currently shipped with Lincoln brand bucket pumps. This has recently changed from the Alemite pump. All grease guns and grease pumps are different. KPI-JCI has found that it takes more pumps to equal an ounce (or pint) with the Lincoln pump than with the Alemite. It is essential to regularly calibrate and qualify your bucket pump and grease gun to maintain accurate greasing of the jaw bearings. Calibrate (or qualify) your bucket pump or grease gun by pumping grease into a 16 oz. container. Count the number of pumps it takes to fill the container. Undergreasing the jaw bearings reduces performance and will cause serious damage to the bearings. page 1 of 7
On page 3, you will fi nd our lubrication recommendations for GT/FT crushers. The picture shows the remote grease for the GT125, but all FT jaw crushers have a similar remote grease option. On page 4, you will fi nd the lubrication recommendations with pictures from our Vanguard Jaw manual. Ordering Grease Contamination Lincoln Pump The new Lincoln brand bucket pump also eliminates contamination. When opening a new bucket of grease, the Lincoln brand pump attaches to the new bucket. The Alemite pumps required the customer to dump the grease from the original container into the Alemite bucket for use. Lubrication Intervals and Quantities Required. Grease jaw bearings once every 10 hours of operation. Apply one pint (16 ounces) of grease into the housing of each outer main bearing and two pints (32 ounces) of grease into the pitman thus providing one pint of grease for each pitman bearing. Both Mobilith SHC007 and Chevron Ultra- Duty HD00 can be ordered from our parts department. Use the following part numbers to order: Mobilith SHC 007 337407-5 gallon pail 265934-15 gallon drum Chevron Ultra-Duty HD00 46-54006 - 5 gallon pail 46-54007 - 17 gallon drum If you have any questions, contact the Service department at 1-800-532-9311. page 2 of 7

Product Data Sheet Mobilith SHC 007 http://www.exxonmobil.com/pdssearch/search.aspx Synthetic Semi-fluid Grease Product Description Mobilith SHC 007 is a high performance, long-life synthetic semi-fluid grease formulated from a lithium complex thickener and a high viscosity, ISO 460, polyalphaolefin ( PAO ) base oil. It possesses excellent extreme pressure performance and good corrosion inhibition which are essential in filled for life gearbox applications. The use of high thermal stability synthetic hydrocarbon base stock contributes to the exceptionally long life of this product, which far exceeds the service life of conventional mineral oil based lubricants. Benefits Mobilith SHC 007 offers the following benefits: Reduced gear wear due to excellent EP properties. Minimises leakage problems and therefore improves shop floor safety. Protects gears, bearings and casing against corrosion. Outstanding structural stability even in the presence of water. Compatible with mineral and synthetic lubricants as well as conventional seal materials. Special Features of Mobilith SHC 007 Long service life even at high operating temperatures. Wide operational temperature range, -50 C to +200 C. Excellent wear protection even under high loads and at high temperatures. Excellent rust and corrosion resistance. Reduced power consumption due to low running torque. Reduces maintenance because of fill for life capabilities. Applications Mobilith SHC 007 is recommended for application in a wide range of medium to slow speed industrial gearboxes particularly those where fill for life service is required. It is especially suitable to applications where high operating temperature and leakage render conventional lubricants unsatisfactory. Typical applications for Mobilith SHC 007 are conveyor gearboxes, remote gearboxes and crane gearboxes where minimum maintenance is desirable. It can also be used for slush pan lubrication of open gears. The excellent water resistance and superb rust and corrosion inhibition of Mobilith SHC 007 ensure excellent lubrication even when subjected to contamination. Mobilith SHC 007 has a recommended operational temperature range of -50ºC to +200 C. Mobilith SHC 007 is compatible with conventional mineral oil and PAO synthetic gear oils. page 5 of 7
Properties Mobilith SHC 007 is an extremely thermally stable semi-fluid grease manufactured from lithium complex thickener, synthetic hydrocarbon base stock and unique combination of additives which are effective up to a very high operating temperatures. The semi-fluid nature of Mobilith SHC 007 ensures maximum flow of lubricant to the critical gear and bearing interfaces, whilst minimising leakage past seal materials.
