Hello. I'm working on a 175 and on page 313, reference #18 of the AGCO parts book it calls for a "special" bolt. The ones that I took out were regular bolts with the heads ground down from a previous repair, so I'm assuming that's what is different about them but the heads are pretty shallow and would like to know the specs on these bolts so I can make new ones as I can't seem to find new ones for sale. Also on this auxiliary hydraulic pump there is a screen on the suction, same parts page reference #3, part #886745M92 that I can't seem to find. Anyone know where I can get a new one? Thank you.
