....to remove snap rings. I use them daily working on tractors. Seems like every thing internal (i.e. transmissions, diffs, axles, ect ) are all held together by snap rings. Especially gears on a shaft.
have a look at your ratchet (if you have a decent one ..... ) the entire ratcheting mechanism is covered / held in place with a snap-ring / retaining ring....
retaining rings are used for securing axles, covers, bushings, bearings,...etc.....very effective, quick and cheap to replace and they can withstand a lot if force of designed right.
On aircraft I usually see them holding in wheel bearings. Output shafts on airstarters, snubber rings on alternators, pretty much any seal/whatever that is on a shaft. The pliers will save you a big hassle, worth the investment.
Snap rings and retaining rings. You will encounter many different types on all sorts of machinery, tools, etc. One set will probably not meet all your needs.
I'm looking at a new set that should give me more uses/choices for different applications that I might need in the future.
Yep. A lot on gearing and ratchets. I bought my pair when i needed to remove retaining clips to replace headlights. You never know when you're gonna need em!
