1010 sprockets VS. 440 sprockets

Post by 58440IC » Fri Feb 14, 2014 6:47 pm

I bought my old 1010 for just the rollers and sprockets. I did not realize there was a difference in the sprockets until recently. I see the 1010 has a much narrower face width. The guy I bought the 1010 off of mislead me on a lot of things so I thought the sprockets were the same. I already put a 1010 sprocket on the 440. It looked good but now that I just got around to the other side, the other sprocket is not so good. So now I am facing using the 1010 sprockets or go back to the 440 ones and flip them around. Any suggestions or input? Thanks. Walt

You have about an inch problem between the 1010 and early 440 sprocket. Late 440 with the beefier final drive uses the same sprocket as 1010 or it is darn close. I think this is a late 59 and 60 models only 440 that have the beefier final. So I am guessing your 1010 sprocket is rubbing on the inside of your bottom roller.

So I had the same problem once, had a better set of 1010 sprockets laying around and needed them on a 440. I just made the 3 pins on the final longer (used bolts and nuts instead of a stud) and put 1 inch of washers behind it. I then put washers behind all 6 bolts between the sprocket and final hub. You could make spacers somehow instead of washers, I just made sure I centered the sprocket in between the bottom roller.

Was it the right thing to do? Probably not, but it worked just fine until I found a good set of 420 sprockets and it didn't do any permanent damage and was easily reversible.

I'm sure I'll get some flack for what I did from other members, but when money was short and I needed it to work I made due with what I had.

The difference between the two is the offset, not the face width. If the face width is different, likely the sprocket was run a long time on a bad final.
Late 440 and 1010 use the same sprocket, what I will call the narrow dish sprocket. This same sprocket was also an option on 420 and 430, so they are out there. Another option is to take a deep dish sprocket, cut off the rim, and weld it on your old centers.

X2 on what the about guys said.
The washers aren't a bad idea, I would've made the spacer out of a full plate so there was a little more contact area when tightening things down.
I actually may have to do this because my left rear sprocket just barely bumps the inside of my rear roller sometimes. The right way would be to move the track frame in on the adjusting tube, but there's not way it'll move so I may make a 1/4" thick spacer to bring the sprocket out.
