The machine has a few broken grease fitting. So I went to Napa and matched up a few sizes sSAE and metric. Both of them only screw a turn then stop .. I can force them in I am sure but would like to know the correct thread pitch. Recommendation? Machine JD 310 E
Are we somewhere around the size of 1/8" National Pipe Thread fittings?
Willie59 I think you are right on the NPT totally forgot that one.. They are 1/8",, I will double check them in am!! Thanks
Well, I'm not sure what Deere used on those machines, but there's three types in around that size; 1) 1/8" NPT, very common at a parts store like NAPA 2) a metric thread, I think it's 10mm, don't recall the pitch, still a fairly common fitting at a parts store 3) 1/8" BSPT, not easy to find in a parts store BTW, none of these three really interchange with the others, they come close, but no cigar. If you have a Deere dealer near you, pick up one or two of the proper fittings, then you can match them up to parts house fittings.
