Too much lubricant in bearings can cause as much damage as under lubrication
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.
