A year or so ago, there was a thread showing thumb screws that were used to hold the grill in place on a d17. Enabled removal and quick access to the power steering fluid fill. Anyone know what size those are or what's used? Thinking stainless steel is the best ------------- D17 Series 1 Allis B- 1939 Allis B- 1945 |

| I think it should be 5/16 dia. Coarse threaded? Just try a bolt that size in the treaded hole and see if it works. I believe the early D series used different style head on the thumb screw than the later models. One was fancier. You can get them on ebay or most aftermarket dealers but they get a little pricey. I think my local ACE hardware store carries the plain standard kind for about a $1.50 or so a piece. |

All the D series tractors that we have, have wing nuts.The D-15 that I drove home new from the dealer in 1962 had wing nuts to hold the grill. I bought a large bag of them at Fastenel for a small amount of money. ------------- B, C, RC, 3 wc,2 wd,3 wd45, d15, d17, d19, d21, 190, 440, 7040, 918 backhoe, 12 roto balers, 7 60 combines, 40, 66,2 72,90 super, sp100, Gleaner E, F3, 3 L2, R62, and much more |

Thanks all. Tractor is down at the Farm and 100 miles away so was trying to nail this down so I can deal with it next trip. And, like Sherman Farms, I may need wing nuts instead (thinking there might be nuts on there now) JoeM thanks for that chart. It's the spade head stainless that I was thinking of. Gary, thanks for the parts no. I'll give it some study. Scott ------------- D17 Series 1 Allis B- 1939 Allis B- 1945 |

My D-17 (Ser. II) has 2 wing nuts on the top and 2 wing bolts on the bottom. i just looked in my parts manual and that is what is listed there as well. I believe I replaced the wingnuts years ago so they may not look original. The wing (or spade) bolts may be original but I can't say for sure. In any event, the bolt and nut sizes are both 5/16" NC.   |
