Hi folks, Another question about my D15. I attached (I hope) a pic of the end of the loader arm. It's worn down to almost nothing at the bottom. I'd like to reinforce it. Can I just weld a 1/2" scab across the bottom, or is that fitting forged? Also, I'd like to replace the pins. The tops are easy at 1", but the bottoms are something odd, like 1.60". At least that's the bore of that fitting and the bucket too. Obviously it's worn a bit because nobody ever greased it, but does anyone know what size those bottom pins are supposed to be? Thanks!

1.625 ... would be 1- 5/8 inch what you can do is buy a 6 inch long piece of exhaust pipe, 1.625 OD , and use it as a TEST to see the size. ... If the sockets are EGG SHAPED, you can take a burr grinder and enlarge in one direction if it is a little TIGHT... that way you know how your new PINS are going to fit. ........... I think a 1 -1/4 inch PVC pipe is 1.660 OD ... if the exhaust pipe is too small. many people have welded up the end sockets.. so YES, you could weld up, or weld a plate over the end of the socket..

| Thanks Steve! All good ideas. The smallest boss on the loader is 1.55, so I’m assuming the pins are supposed to be 1.5, so some bores are wallered out. That’s a starting point anyway. I might reinforce the arm, and hard face the reinforcement. That oughtta toughen er up a little. |

40 mm pins are 1.575 inch 1-9/16 inch pin is 1.5625 inch I have welded up a couple bores and "hand ground" out 1/8 inch or more to get to a specific size... With a good air grinder and hard 1/2 inch bit its not hard to do. i have something similar to this ( 1/4 inch shank) with 1/2 or 9/16 cutter to grind out the sockets to size..  ------------- Like them all, but love the "B"s. |

A steel bushing welded in the hole would give it a lot of strength of course you'd have to do the bucket holes too.Machine shop work but it would really beef it up. |

If it's forged, it's steel. Welds like any other steel. I cast, it could be either steel or cast iron. The pattern of the sparks when ground will tell you. ------------- 1970 190XT, 1973 200, 1962 D-19 Diesel, 1979 7010, 1957 WD45, 1950 WD, 1961 D17, Speed Patrol, D14, All crop 66 big bin, 180 diesel, 1970 170 diesel, FP80 forklift.
