1300 cc tappet adjustment

Recommended Posts

You will think I am a plonker for asking such a question having adjusted tappets on a number of classic cars. I'm familar with the screw stud and lock nut type but not the Ford one. Haynes says  adjust using the lock nut but I cannot undo any of them and they do not want to budge even with a 10 inch socket wrench (not too much force) as thinking these hollow nuts will just shear. I  must be missing the point somewhere as do not understand how they work/adjust/lock.

Not done a ohv engine for years but seem to remember you turn adjuster clockwise to tighten or anticlockwise to slacken....it needs to be tight so gap stays correct.
Much easier than having a seperate lock nut......if my memory serves me right

So they are tight/binding threads meaning difficult to move in either direction. My gap is too small so need to undo assume RHT. So a bit more force and they should move and not shear, hope you are right.

if your using a piddly 1/4 socket and ratchet, they will seem excessively tight, on the other hand if you've got an inch drive set on there they wont lol

be sensible and use a 3/8 OR 1/2 Inch drive set and you shouldn't have too much trouble

Also use the rule of 9 for adjustment, no1 valve down to adjust no8, no2 valve down to adjust no7 and so on.
"The rule of 9"....its all coming back to me now!!!
