Hi guys,
Just wondering if anyone can tell me what size tap I will need to chase/clean out the main cap threads?


Thanks, Dennis.

Conventional wisdom is to use a thread chaser rather than a tap as the tap may cut  the threads a tad.

Here is another style, with a large assortment, a thread restoring kit.  I have a Craftsman version of this (older, Made in USA) and it is a quality product.  The threaded portion is more like a standard nut or bolt thread but flutes are cut into the threads, similar to taps and dies for dirt and grime removal.  They are hardened so that you will strip a thread quite effortlessly, if you use the wrong thread pitch by mistake. Guess how I know.
The thread files are also very useful.
