During lockdown i found this tool and wondered if anyone could identify it, i seem to remember my dad saying it may be a hair spring valve tool.
Cant even remember how i came to have it, if anyone can identify it and needs one then they are more than welcome to have it.
The only identifying mark on it is the number 114.
Working on hair springs. Can’t think of a use for such a tool. Does this open up to “what is this for” because I got a few I have no clue what to do with...
Yes it is a hairspring valve tool. I have one similar. Yours would be for a specific head. Unlike mine which is universal. The one I have can be adjusted as the two long bolts are on a bracket which slides along the curved part of the tool. If I could find it I would send you a pic. But you know how it is, I have put it somewhere safe !!!!
Andrew I would never have worked that out. Can you say how it would be used? Intrigued.... are there parts missing? Think I’ll show some of the odd things I have to get them identified. May not be bike relate but who knows till someone says what they are .....
Jon, I use this tool on my 1954 G3L Matchless. If you go online and google 1951 maintenance manual for 350 and 500 matchless and go to page 29 you will see how it works.
The tool is bolted to the head and the two long bolts are wound down onto a plate which in turn compresses the spring. This allows the collets to be located onto the valve.
The tool that Ian has appears to have the long bolt mount welded to the frame whereas the one i have the long bolts can be moved along the curved shape to line up with the angle of the valve. So I think Ian's is for a specific head. Hope this helps
So my Dad was right that it was a hairspring tool, just couldn't remember what bike/engine it was for.
That is identical to Ian's. Thank you Andrew, it makes sense now.
