Is there enough meat there to drill and tap for the next larger size?
Don't know yet. I can tell you the bolt head size can not be increased without going to a different style fastener.Is there enough meat there to drill and tap for the next larger size?
The one that hold the deck plate to the gear box. This is the top picture. To much stuff to move to turn it 90° for the bottom picture. Right now its all dirty on count of the gear grease leaking out.Which holes exactly are we talking about? Pix?
Sorry but not happening this evening. But yes I guess it needs to be done if for no other reason than to check to see if this is truly a housing thread problem and not just stripped bolt threads.While appreciated, that effort is not particularly informative.
You need to flip it, get the bolts and deck off and show us what kind of meat we're working with.
But from what I can see I highly suspect there's room to go a size larger.
