2. With the conveyor running, make pulley, snub roller, or return roller adjustments of 1/16 of an inch, allowing the
belt several revolutions to react between each adjustment.
NOTE: IN MANY CASES, ADJUSTMENTS OF THE SNUB PULLEY AND RETURN
ROLLER ARE SUFFICIENT TO CENTER THE BELT OVER THE DRIVE PULLEY AND
TAIL PULLEY
3. After the belt has been tracked WATCH IT CLOSELY for a few days making any additional adjustments
required during this initial stretch-in period.
4. On longer units a short section of laced belt called a “Dutchman” is added to the overall length of the belt. As the
belt is taken up the “Dutchman” can be removed to allow the conveyor take-up additional adjustment.
5. Make sure maintenance personnel look over the conveyor belt at least weekly and check on the following:
Belt is tracking properly and is not slipping on drive pulley.
Pulleys, rollers, deck, etc. are free from foreign material that could fall in or stick to the belt
and cause damage.
Belt is not being frayed or cut by siderails, chutes, hoppers, etc.
That belt lacing is not being damaged and belt connector pin is staying in the lacing.
MOTORS
1. CLEANING - All motors should be kept free of dirt and grease accumulations. Open motors should be periodically
vacuumed to remove dust and dirt from the windings.
2. VENTILATION - For best results motors should be operated in an area where adequate ventilation is available.
3. TEMPERATURE - Most of todays smooth body T.E.N.V. and T.E.F.C. Motors run hot to the touch. As long as
maximum ambient temperatures are not exceeded, and more importantly, ampere draw is within the allowable
range, there should be no need to worry. (Both of these limits are found on the motor nameplate.)
4. LUBRICATION - Most electric motors are lubricated for life and under normal conditions require no more
lubrication. Under severe conditions where additional lubrication is required, use the following chart as a guide.
THE FOLLOWING CHART IS BASED ON MOTORS WITH GREASE LUBRICATED
BEARINGS, RUNNING AT SPEEDS OF 1750 R.P.M. OR LESS, AND OPERATING
WITHIN AN AMBIENT TEMPERATURE RANGE OF BETWEEN 0 DEGREES F. TO
120 DEGREES F.
Typical lubricants that can be used:
Chevron Oil Co. - SRI#2 Gulf Rening Co. - Precision #2 or #3
Shell Oil Co. - Alvania #2, Dolium R Mobile Oil Co. - Mobilux Grease #2
Texaco Inc. - Premium RB Sinclair Rening Co. - A.F.#2
