Been working on the Morris engine, it's a 3.5 litre side valve, a engine pinched from the contemporary 1930's Morris 25HP saloon with a few ancillaries changed around eg carby and stuff
I obtained a set of NOS +20 thou pistons years ago, so this particular engine is getting a rebore soon. I came to the dreaded job of removing the head studs in the block
OH dear ... this type of job has hidden dangers and any number of things can go wrong .
Being of sound mind Hmmm I decided to make my own stud puller .
The wedge is a piece of square section file , it has been ground to a taper . The puller has been used with success ! The wedge teeth grab the stud and the more turning force you add, the wedge will pull itself in, self locking
Heat the stud at the base to a dull red, let it cool and apply the WD40 or whatever , PB blaster is good .
