346 chainbrake spring

[GardenKit]

The last thing you should use to compress the spring is a screw driver, if that screw driver slips off the end of the spring it is going straight into his hand, which is why we never used this method during service training.

A good generalisation ADW, but as you will see in the video, I drew particular attention to the shape of the screwdriver and that it fits INTO the spring.

 

With an insertion of around 10mm, there is no way that screwdriver will slip.

 

There is also evidence on the video that experience has taught me to be careful:biggrin:

Point taken, but whenever i see a screw driver in the end of the spring it sends a shiver, the long nose pliers are far better, they fit right down inside the spring, the actual service tool is a anti vib spanner modified by removing one leg, again it fits well insde the spring and has a t bar top so as to make pushing easier, try the pliers, you might like it.

try the pliers, you might like it.

 

Tried the pliers today. Did not like it.

 

The reason was that the pliers are much thicker than my screwdriver, presenting a round profile as opposed to my flat one.

 

This meant I could only catch a very small amount of spring onto the edge of the recess before extracting the pliers. This made it much more likely to have the spring pop out before being able to push it fully down.

 

But I have to admit it would be my second choice and most people are more likely to have long nose pliers in their box than a screwdriver like mine.
