Assembling and Disassembling Drive Chain
The components of the drive chain are hardened parts. Striking
these parts may cause metal chips to break off from the chain
or the tools used resulting in personal injury.
During all stages of chain disassembly
and assembly, wear
safety glasses to
prevent metal parts or chips from entering
your eyes and have personnel in the
immediate area do likewise.
Chain-Link Pin Removal
1. If chain is of cotter pin- type construction, remove cotters.
2. If chain is riveted type construction, grind pin heads off so pin
ends are flush with the linkplate.
3. Drive pins out of linkplate using a Diamond pin extractor
Model P/N 113 or 135. Some multiple strand chains or large
pitch models will require a hammer and punch or a press to
remove the pins.
Installation Of Coversides
Diamond Chain coversides are manufactured three different ways:
■ Slip Fit
■ Modified Press Fit
■ Full Press Fit
Installation of Spring Locks and Cotter-Pins
After coversides have been installed, install spring locks or cotters
(depending on chain design). Avoid using bent or worn cotters or
spring locks. After spring locks (or cotters) are installed, lightly
tap pin ends to position these parts snug against the coverside
for additional support.
