Master cylinder snap ring trick
« on: September 04, 2009, 03:55:38 pm »
After rebuilding the master cylinders on both of my bikes i've got a helpful hint to share. The first time i borrowed a friend's very nice, expensive channel lock brand snap ring pliers. They had removable tips which did not reach the snap ring. I had to replace them with filed down finishing nails, which worked, just not that great.

I found out today on the second bike that the dirt cheap, crappy snap ring pliers that i got on sale from harbor freight a while back fit down there perfectly. The jaws are so long and thin i wouldn't trust them not to bend on any snap ring heavier than the one in our masters. But boy was i happy when they worked. Best 3.99 i've spent at that store.

You can't do every job with nice name brand tools!

I had a similar problem with my MC rebuild, luckily I have a bench grinder and was able to profile the plier noses on that to suit the very restrictive recess around the MC piston shaft

Not sure if posting in these threads are bad or not but I am just tossing out 2 cents or half cent whichever and only to help. But I had a devil of a time getting that thing out. I noticed that the main issue I was having was that I couldn't get the downword pressure to sustain enough as I also pulled upwards. So I took my snap ring pliers over to the vise. Laid them gently on the edge of it. Just to where about a hair of the tip was hanging over. And gently taped on it with a hammer to put a slight bend on the tip of the pliers. And I mean just a hairs length at the end of the pliers. Gave me just enough that when I did apply the downward it had enough to wedge itself underneath giving me the leverage I needed to gently pull upwards.

Hope this helps someone!
