but I really wanted a nice, easy to use 'first step' that would both work well and look good on the machine!... I pondered... looked under a bit, but no real time on project... other things to do. so other week, I did take the time and low and behold... I found the center implement bolt holes cast into bottom of the diesel tractors heavy massive manual transmission.
and
! but metric no doubt, but what size?
so I went to Lowes and got 6 metric bolts about 7/16ths SAE and figured one would fit. and one did. easy screw it in!
and so I now had my location point and soon had it all figured out how I would make a cool new aux step for my new tractor... not for $800.00 but for about $10.00 or less!
yes, $10.00 or less...
here is my design. I first made a pattern to the bolt holes in trans. cardboard and small ballpeen, tapped the hole areas and made a congruent replication of the pattern, no measuring required. I will trim up an 18" 4x6 and then a 2x6x55 to reach out past the tractors sides to make the step pad. the center bolts are 4 M12-1.75 and I need 160mm. so had to go to specialty fastener store... got 4, flat and lock washers, too. out to the ends of each side of the 4x6 I will use 2 per side 5/16ths lag bolts to further secure the 2x6 to the 4x6...gluing the 2 together with Lock-Tite III wood glue. (waterproof) then once holes drilled, etc will sand, primer and trim out in a New-Holland blue, adding foot step pads at each end. here some pix of work parts, bolts and design-in-progress. I bot a 10 mm hex socket for the socket bolts, but prob will just use the one I made up... 3/8ths with brass shim. besides the store bot 10mm is a loose fit and the one I made is nice and snug. I like snug!!

M12-1.75 x 36 mm thread ID finder... screwed right into the trans underside bolt holes like the 'magic key' for curtain # 3 and... started the car lol...

bolt place said they had cap screws, 17 in stock, but at counter had -0-!
so a hex head socket needed... $7.00 at Lowes... but maybe I can make one... or adapt it up well, so I did. that is brass shim stock .003 cost me $12.00 for the roll back in 1988 or so. I have used that stuff to shim up more than just a few sets of rod bearings on v8s... OHV cam set ups... and main bearnings... the stuff is awesome... bulletproof! time consuming... but beats a new engine. rattling rods at 145,000 miles?... shim em up... dress them out, reset to running range .0015 to .0025 and good for another 50,000 miles... easy!
