ENCLOSED GEAR CASES

OPEN GEARS

EXTREME TEMPERATURE OPERATION Too large an amount of grease causes overheating of bearing! excessive churning and rapid breakdown of the grease, rupture of the seal and leakage of the lubricant past the seal. If a bearing shoJld run excessively warm because of over filling! it is advisable to remove the pressure fitting and allow the excess lubricant to escape. The bearing should be allowed to operate and purge itself of excess lubricant for 10 to 15 minutes before replacing the' fitting.

The lubricant in all gear cases must be kept at the recommended level. Check the lubricant at regular intervals at the dip stick or check plug.

When making seasonal change of gear case lubricant, the used oil can be pumped out into a drum or container, for final disposal. Drain all remaining oil from the case through the drain plug opening. After draining, the gear cases should be flushed clean with fuel oil or a light petroleum oil, before re-filling. Oil from the swing gear cases, can be removed by using the circulating pump. Gears and pinions, which are not enclosed! should be kept coated with a good grade of open gear lubricant (OGL), as recommended in Lubricantion Charts.

The lubrication specifications in this manual covers the lubrication requirements of the machine when operating within an ambient temperature range from -20 degrees to 110 degress F. If this machine is to be operated at temperatures below -20 degrees or above 110 degrees F., contact the Marion Power Shovel Company, Inc., Marion, Ohio or local supplier for special lubrication recommendations. Give full particulars concerning your conditions of operation . •

NOTE:

AUTOMATIC LUBRICATION Unusually dusty and dirty atmosphere, high humidity and/or extreme temperatures can alter the effective life of a lubricant. Therefore, it shall be the responsibility of the operator and/or owner to determine the most effective lubrication intervals in accordance with existing environmental conditions for all components, bearings (plain and anti-friction), gear,' gear cases, etc.

Five (5) automatic lubrication systems are used on this machine, each serve a separate function.

AUTOMATIC LUBRICATION FOR OUTBOARD ECCENTRIC BEARING This system is standard on all machines. Because of the high demand of lubricant for these two (2) bearings, (one on each side of the machine) and the frequency of application, a completely separate system is required. This system only operates during propel.

The system provides lubricant to sixteen (16) points on each bearing. The amount of lubricant discharged into the bearing, each count per cycle, is fixed. To increase the amount of lubricant in the bearing, the number of counts per cycle or the time intervals between cycles, must be changed. For an initial the system is set at two (2) counts per cycle, with five second time intervals between cycles. Instructions for changing the cycle count and the time intervals is fixed'to the inside cover of the timer.

If the system does not complete the cycle in 80 seconds an alarm sounds and a red light will indicated a lubrication system failure.
