- 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.
