Heller Aller mainshaft

[Big Job]

Short story; at my sons farm one day the wheel found on the ground all bent up. The main shaft snapped
in the area of the shaft seal. So first I will ask here, nothing on ebay or the net. Its a Heller Aller 'Baker"
run in oil /Date of mfg. March 1973. Push comes to shove no choice, to machine one (I have a machine shop)
This week we finished the wheel and painted. Just a guess the shaft is about 2 ft long and a odd diameter
of 1.309 ? don't know we have not removed the mill from the tower yet. All paper work that came with it
is next to useless........thanks Sam

You might take it all apart to make sure what you need to make. On the head is "MOD 8" or something. That's the size of the mill, 6 ft 8 ft etc. I don't remember what the last one I took apart was, but usually ( for the most part) mainshafts in lots of mills are fairly simple, and standard size cold roll. If you take it all apart, you can look at the mainshaft in its entirety and make sure.
Also, as far as I know, the mill has no "bearings" per sae. The iron that shafts run on is heavy on the graphite if I remember.

When i rebuilt my Heller aller the pinion gears had tapered pins.they could only be knocked out one way

Yes tapered pins I have been into these mills in the past....

Is this an oil bath mill or the open frame? Wheel Size 8' or 10'?
Let me know and I should be able to help. Todd

HY Todd, its a 8 foot wheel, run in oil, it was delivered March 1973. My only holdup is setting a date when
my two sons are available along with the bucket truck. No way these ole bones going up there lol. Actually machining a shaft is freshman high school easy lesson. And next is the tapered pin, so I will need a tapered reamer, or I just may cut key-ways (shaft & the two gears with set screws) don't know yet till its in the shop.
Anyway one week with hammer & dolly with the wheel all trued up and painted so I saved 7-800 bucks for a new wheel then the shipping cost? Imagine my father bought this whole thing for $750 delivered in 1973.

Good for you! If you need any other parts, let me know...

[Big Job]

I sure will Todd 'still waiting for some young bloods cause my ole bones no way going up there LOL as far as machining the main shaft, thats high school 101 and then the tapered pins so that calls for a tapered reamer
that I do not have so I think it will be keyways with set screws .......sam
