Valve adjusting tool set, M14-P/Houssai - Repro
This pair of reproduction Factory valve adjustment tools is made from heat-treated chromoly steel, plated for long life.
These tools suit either Vedeneyev or Houssai engines.
Two Additional functions were designed in - the first completely unrelated to valves.
The square hole in the socket handle is for installing/removing the 7mm plug in the right hand side of Nose case (where cast-in passages supply oil to the Prop Governor.)
Second, the slotted cylindrical boss on the other end the blade tool will help you over-center the wire ring that secures the valve cover.
Ideal wire tension is such that you can almost over-center the D closure with your finger or thumb. (So adjusting the threaded D to where you can barely do it with all the newfound leverage of this tool is not the goal. )
Instead, use the added ‘feel’ from this tool to evaluate and adjust the wire loop tension to the ideal value. Any tighter will shorten O ring life unnecessarily.
Used in the valve adjustment process, the 12 point socket releases the valve adjust nut, and allows you to hold it where the nut is just starting to ‘bite’. Then insert the blade and adjust the slotted center to the required valve clearance (using a shim between rocker and valve.)
Holding the blade tool still at the desired clearance, use the socket in your other hand to snug the nut.
With a little practice it’s a great procedure for getting your valve clearances right the first time!
