I try to complete WLA motor cases. I have a problem with screws in gear cover. Part List shows that for relief pipe there should be 10-32x1/2" (catalog number 036) and for shaft timer 12-24x7/8" (part number 044). When I try screw this sizes it does not fit! For timer shaft ideal are 10-32 and for relief pipe I can't figure out. What sizes of these screws do you have? Is there a mistake in parts catalog (TM-10-1482)? If there would fit bigger screws that these supposed to be I would think that somebody increased size because destroyed thread. But in my case there fit smaller size! (sorry for my english, I'm Polish).
