Good day, i have some timing problems ( lost compression after some engine work) Anyone has an idea which spanner size fits the oil pump worm on a WDCO? Can not find the correct size. Leaves me clueless. If I am right...turning right is loose?

Thanks in advance,

Jacco

This is the bad boy I am talking about

You need a 3/4 AF spanner Jacco (that's 3/4" "across flats", as for UNF and UNC fasteners). Alternatively a 19mm spanner will also do the trick. And yes, indeed, left hand thread on this one, so turn clockwise to open!

Great Jan thanks! Grinded down an old 19mm to make it fit behind the worm. On we go! Thanks,
