Hi all, I just got an AC self-unloading wagon (power feed box) with a non-working front apron. The main apron that draws silage forward works fine, but the smaller one that pushes stuff out the side outlet needs to be fixed. For sure I need to replace the chain that brings power over to the gears that run it (not the apron, but just the chain), and the bevel gears that send power to that chain also are mashed up. I'm looking around for even a parts catalogue, but I can't find anything. Does anyone have any recommendation for how to find replacement parts? I know these wagons aren't common anymore. Thanks so much!

I have a hard copy parts book for the self-unloading forage wagons and power feed boxes, so if you can post a pic of the parts you need, I can hopefully find the part # and Mike, myself and others might be able to come up with the parts for you. ------------- www.awtractor.com A&W TRACTOR 920-598-1287 KEEPING ALLIS-CHALMERS IN THE FIELDS THROUGH THE 21ST CENTURY |

OK thank you all so much- I really appreciate your help. I'm attaching a few pictures to show what I'm describing - there are the bevel gears that are gnashed up, and the chain (which is powered by the bevel gear and transfers power to the unloading apron) has broken. Do these look replaceable?   uploads/16450/gnashed_bevel_gears.jpg" rel="nofollow - uploads/16450/gnashed_bevel_gears.jpg |

Soildground, Nice older AC power feed box. The first AC power feed silage box (supplied by Calhoun Co., Cedar Falls, Iowa) production was marketed from about 1959-1962. It was usually monted on a 7 ton gear. 1964& later Power feed boxes were built by AC at Laporte - courteous Norm Swinford's 1914-1985 AC Equipment book. If your wagon sits on an AC running gear, it should have an ID tag located on its rear frame. If you tell me the numbers from that ID tag, I can tell you which gear it is. IMO, your wagon’s bevel gears don’t look that bad. That looks like typical wear on bevels. If you haven’t tried running them, attach some 2040/2050?? drive chains to it’s unloader & given it a turn by pto. Buy “A”(USA made)not “I” (Import made)replacement chain. US last longer, Import stretches quicker & wears out sprockets. Web links below. It’s unloader chain & slats looks like it uses a common “steel detachable chain”? Maybe 55 size - 1.281” outside width.?

If it’s bevel gears are worn out. Their original AC part number is 515366. They are 18T & held onto their round drive shafts with a woodruff key part # 905845. It’s unloader conveyor uses a 55H detachable chain, part# 921052. The conveyor drive chain part# 918563(108 links). It doesn’t mention its size. If its sprockets measure 1” between teeth(centers) then it probably uses 2040 chain. If it’s sprockets measure 1.25” between teeth, then 2050 chain. If teeth are 1.5”, then 2060 chain. |

Wow, thank you all so much for this information - I'll measure the chain to best match it. And yes, it does have an ID plate on the back. It says: Cat. No. 2013847 Serial 7 5999 Allis-Chalmers Mfg Co

This photo shows a picture of the apron's conveyor drive chain configuration near the bevel gears. Thought that might help Solidground know how to route it?

 Parts (2) of number 5 are the bevel gears located on the backside of it's pto input shaft.

Nice looking floor yet on that discarge, I take it that rope is for opening and closing the box into the discharge chute? Must have been parked clean or had no silage in it to not be rusted through. ------------- "Thank you for your service Joe & the Ho"-----Joseph Stalin |

Soildground, I curious - what did your wagon’s conveyor drive sprockets measure between their teeth? Mikez, that’s amazing that you might have those bevel gears in your old new stock. you said, "have card on 515366 and have a box’s different of chain ." So I'm thinking that your part numbers are listed Numerically by card catalog? If that's correct, here are ALL the part numbers for the AC Power Feed Box. How many of these might you have in stock?  |

well ac7060 the bevel gears I was thinking of fit an all crop harvester but yes the cards are the index filling cards. And have one one the number you posted. And one on the chain 921052 and it’s a-2050 and on box written a farmers name and “forage box” . I’ll check out what else from your parts book. Are you looking for something also.

Oh and the old roller chain measures a pitch of 1 1/4 inch, with a inner width of around 3/8 inch. So that's the standard 2050, I think? |

I have a neighbor that has an old AC forage box sitting in his pasture that I bet could be had for almost nothing. I am about 4 hours north of you. They were a very good box. If I remember right the bed apron (lags) ratcheted like many old manure spreaders, rather than a worm gear drive.

Mikez, So these index filling cards that you have, were they used in conjunction with a microfiche machine(scanner) like the dealership had back in the 1970-80s? No I'm not looking for any power feed box items. I just thought if it would help anyone, I'd share it's whole listing of the parts numbers.

| no these were before that. I think iv see 1956 on some of them. You had the counter top parts book set up and of course the stacks of books under the counter lol. Then you look up what the customer is looking for and get the part number then go to the index cards, ours are in a wooden box also on counter and find part number which tells the bin location, simple description and how many on hand. Then your supposed to mark what you take out or add into stock. |

Hey all, Thank you again for the help on figuring out our wagon issues. I've finally gotten around to starting this project, and I'm hitting an issue that I hope you can give me advice on. I've got a new bevel gear (part number 515366 - it's #5 in the diagram you gave, AC7060IL). Now I can't for the life of me figure out how to replace it! The two gears are at a 90 degree angle - I can't remove either because they block each other. So I was thinking that the solution is to pull the whole shaft out the front so the gear can just drop down? But I think the woodruff keys (which I can't remove) are hitting the bearing assembly or something. Suffice to say, I can't pull the shaft forward, but I can't pull the gear backward. How do I remove it? Thank you so much for any insight - I feel like the solution must be obvious, but it's not occurring to me. )AC7060IL

To be clear - here's the diagram again that I'm referring to. I'm trying to remove the #5 gears, but they block each other and they each go through same L-shape bracket, holding them together. What's the trick? uploads/16450/ACpowerFeedBox_gear_parts.JPG" rel="nofollow - uploads/16450/ACpowerFeedBox_gear_parts.JPG

Drive shaft in through gear till you can get the key out then pull the shaft out.

Yes, I see it now, thank you so much! Push the perpendicular shaft in to get the key out, then pull it out and the gear drops down. Then there's room to pull the gear off the PTO shaft. Thank you tadams!
