Well,,my Pin puller came today from the machine shop, so I go out and try my luck at pulling a brake pin. Alot of PB blaster, and apply the tool, I ran it down until it wouldn't move,  using a small ball pein hammer I start tapping the middle of the pin and outer housing,,,and I see my new tool relax,,I think,,OK,,I've pulled the head off the pin,,remove the tool?,,and,,  It MOVED!!!!,,knowing now,,I've got'er made, I just took my time,put tension on the tool,,and kept tapping the pin rather hard, each time seeing the tool relax, next thing I see, is the end of the pin coming through!  So now I KNOW I'm home free, so keep up with the PB Blaster, and tapping, and a 1/4 turn on the tool  And out she came!, The whole process took me roughly 1 hour, NOT getting in a hurry, and just letting the vibration of the hammer, and tension on the pin do it's thing.  Did not damage the head of the pin amazingly, FULLY expected that!,,I've heard stories,, but after wiping the pin off, it looks like the outer part of the pin is where she REALLY gets rusty  ,,,,NOW,,,the BIG question,,1 more to go,,can I do it again?,,THEN,,I have my WD to do,,,could I BE so lucky???!!! |

Larry did you dream this tool up, or is it a tool you purcased. It looks like the peach to have in the tool chest. Roger ------------- '64 B-10, '58 D-14, '60 D-15D, '58 D-17D, D-19, 170, 2-185D, 190, 68 D-21 11, 72-220, 7000,7030, F-2 G,w/5 Heads,L-2 G, 330 No-Till |

Thank you for the excellent pictures. Dad's WD needs brakes, and I've been stalling so far. He says he just drops the loader if he has to stop, and so far he's content with that. I'll definitely buy that tool when I have a go at them. Good luck with the rest of the pins! ------------- 1939 B, 1940 B, 1941 WC, 1951 WD, 1952 CA, 1956 WD-45 |

WJohn, and B170dr, http://www.agrimsontool.com/index.htm" rel="nofollow - http://www.agrimsontool.com/index.htm This is the place that has them on the shelf!,$175.00,,and money WELL spent! BUT, from what I've learned from guys here on the forum,,BE CAREFUL!,,cause this bad boy WILL pull the head RIGHT off the pin! Like I said, I just cranked her down fairly tight, didn't "jump up and down" on it, then took a 8 oz ball pein hammer, and knocked the crap outa the middle of the pin and kept squirting PB Blaster on it!

| Larry, a small tip. I know it sounds counterproductive, but once you get it out 3/8 or so, lube it up and drive it back in. The rest of the extraction will go smoother. Ya dun good and were patient doing the job, that is the key. |

| Larry great pic's ! thanks for posting. When you re-assemble clean the pin using wire wheel and then coat with anti seize not that you will ever take it out again but still the right thin to do I think. In the first pic it looks like you were able to get the brke rods out ok I have twisted the threaded end of those off but not as big an issue to deal with as those pins. In my opinion a brake job on these tractors is the hardest thing to do! |

Thanks for the encouragement guys! I'm thinking on putting stainless steel pins back in. will get the stock metal here localy and turn them out on the lathe at work.

All this talk about stuck pins makes em think I might be the only guy that ever had a brake pin fall out. My B's left brake just quit all of a sudden last year and I found the pin almost all the way out. I put a bolt back in cause the pin is too loose

CTucker! HA HA HA,,Dale Haymaker says ever now and then you'll find one that'll come right out. But from my understanding, that is the exception to the rule usually,,but I AM still learning here! I don't have NEAR the experance most have on here in the repair arena on AC stuff!

after doing those brakes on the neighbors tractor i added to the periodic maintenance chart and i quote. rotate pin with a vise grip and give them a shot of the good stuff at least at the beginning of each season and have mercy on the next fella that owns the tractor 50 years from now

is that tool specific for that diameter shaft or can it be tightened down all the way to say a 1/4 inch shaft if so that would be really really really helpful when trying to fix some twisted off broken stuck old rusted buggers that like a good fight to come apart and that is the theme it seems on the stuff people bring me

Allismanamp, it is just made for this application. It's two halves that clamp around the end of the shaft and lock into that groove,  |

| Got the second pin out tonight with the same method as mentioned above and without any tore up parts, now comes the REAL challenge, pulling the pins on my WD, hope my luck streak isn't over! |

Your on a roll. Do not get over confident.....take your time. I was lucky, both of mine came out with a little soaking and about an hours worth of pulling.

SUCCESS!!!!!!!,,pulled the hitch and brackets off to make it easier to get to the pin holes. just kept tension on the pins, and tapped them with the hammer in the opening where you can see the pins,  the lower pin in the picture was on the right side, and it came out easy,almost scary, thought for sure I'd pulled the head off, but the puller stayed on the tractor, so I just stayed with it. the pin in the top pf the picture, wasn't so nice,It put up a pretty good fight, but I won! now I've got to clean out the holes good, but I can start on the BIG project, replace the transmission gears!   couldn't be happier right now!!!!

I see new brake pads on E-Bay with rivets for somewhere around $15.00 to $18.00,,,any one know if they're any good? Or should I get them from some where else?

The first one I ever did was years ago, rocked the pin back and forth with a vice grips, put a big screwdriver in the pin undercut, and they came right out. No such luck with the WD I have in the shop now. Have an Agrimson tool on the way. LOL ------------- Most problems can be solved with the proper application of high explosives. |

That tool is a little salty but if you price out the pins it evens out, plus if you do more than one brake job it's paid for itself.. Great pics of the tool in action Larry. ------------- been there done that, not doing it again... |

I would think an impact wrench would work well with that pin puller. Dusty ------------- 917 H, '48 G, '65 D-10 series III "Allis Express" |

Dusty, two things about that, the first and BIG one is, there's no room to get an impact in between the final drive and the tool, (I thought that too though before I got the tool and tried it)
The second thing is, if you COULD get one in there, you'd probably break the head off the pin with the effort the impact would put on it!,,caution is the key there to successful pit romval is what I found!
