    How to tap a Diff housing?

    Due to a modification I now have a diff housing installed but it has no breather fitting.

    My question is does anyone have any great suggestions on how to drill and tap the housing to minimize/avoid any swarf/steel getting into the housing?

    I am trying to avoid having to take the whole thing out and tip upside down to drill and tap for the breather fitting.

    Thanks in advance

    Grease on the bit and tap.

    It's what I've always done when removal/disassembly is impractical.

    What a great idea RIck130 - thanks.

    I was thinking of using my welding magnet to put near the drill bit or a vacuum cleaner but what you say makes sense

    I am just being lazy with this - got everything assembled and just doing brake and breather lines and then realized there was no fitting on the new read housing. So just trying to avoid taking it off.

    I want to fit - then run for a short while then I will do an oil change to be safe.

    Thanks

    Waaay back, we used to use grease on a tap when tapping out damaged spark plug threads or inserting helicoils in same. If it's good enough for that, it's good enough for a diff.

    Makes a lot of sense - thanks POD and Risk130

    I would not have thought of using grease but it makes perfect sense when you think of it.

    Will be doing this tomorrow am when fitting the lines!

    Yep, I was taught that trick as a young apprentice waaay too many years ago.

    So long in fact I've started using sentences like "back when I was a young fella..."
