RE: [DML] Dye Tapping the timing Cover....Help :)

["John Hervey" <john@xxxxxxxxxxxxxxxx>]

Mike, I have re threaded many holes but I have never drilled one out and
retapped it to a larger size. Did you try putting a small piece of metal in
the hole like a paper match and then re insert the 7mm screw. That would
tighten it enough to hold most likely. I have even used tin foil. If you
need to retap. Then practice with a piece of wood.

Hi

I need to retap the lower AC belt / pulley arrangement, the threads
on the lower 7mm hole are stripped and hence as i cant tighten this
enough i have a slight weep from the blanking plate / gasket behind.

I have never retapped a hole and whilst i have purchased a new tap
and dye set there are no instructions / advice on how to do this.?

Thinking of putting in a 8mm thread for a new bolt, will i need to
redrill the hole or am i ok using the existing.......

Thanks All

Mike
