FACTS

  • Too much lubricant in bearings can cause as much damage as under lubricatin
  • Inner races for Torrington needle bearings are hardened.
  • Most common North American ball bearings have always been metric dimensions.
  • Eccentric locking collars for bearings should be tightened in the direction of shaft rotation.
  • Tapered bearings – there can be as many as 15 to 20 cone numbers that will fit the same cup number and vise versa.
  • When you change your chain – check your sprockets for wear. Worn sprockets will cause your new chain to fail fast ( the same applies for belts and sheaves ).
  • Weld on sprockets are available from our stock with hardened teeth.
  • The part number on an A, B, C, D, and E belt is the pitch length, not the outside length of a belt (eg. an A90 belt is not 90 inches on the outside).
  • Hydraulic pressure hose should not be used for hydraulic suction lines.
  • Pioneer poppet style couplers and tips are not interchangeable with the conventional ball style.
  • Black iron pipe fittings should not be used on pressures exceeding approximately 600 psi.
  • Shaft couplers will handle less horsepower as the speed decreases.
  • Helicoil thread repair inserts require a special tap to install. Standard thread taps can not be used.
  • Grade 8 bolts have a higher tensile strength, but are more brittle and break easier under side thrust.
  • Standard bolt thread lengths are two times the diameter of the bolt plus one half an inch.
  • Standard nitrile o-rings can not be used for automotive gasoline.
