440ICD Track shoes on backwards

Post by jimmydiesel » Sat Aug 13, 2022 6:30 pm

I bought a 440ICD 602 outside dozer earlier this summer. The previous owner had replaced the track shoes and chains with some with better chains from a 440IC 831 track loader. The master pins had been replaced with 1” bolts. I ordered new master pins from Lavoy and installed them. After I got it back together I noticed the track shoes were on backwards. I checked the chains and they look to me to be on the right direction. I have done a couple hours of dozing with it and not had any problems.
If I turn the tracks around the chains will be backwards. I really don’t want to reverse all the track shoes if I don’t have to.
So my question is can I leave it as it is or turn the tracks around or is it best to turn all the shoes around?

The way the pads are now, they will tend to push dirt and small stones between the pads. Hard to visualize, but look at the pad on the ground, and look where the pads interact. The way it is now, it tries to scoop up stuff and jam in between the pads.

Is that like the nice way of telling me that I need to stop whining and just rotate the shoes. 😀

No, just an observation. I have a set on a 420 that is the same way.

Can you just 180 the track or does the chain have to run one way? Not different than backing up?

Chain is supposed to run in one direction.

Hi,

The idea is you will be putting a lot more force into the chain going forwards than backwards.

No doubt more force forward most of the time. I'm still looking at the chain picture and try to grasp why it makes a difference? Either way, you're pulling on the links. I was trying to see if it was also a factor of getting dirt in there.

Hi,

In forward, the force is on the first two teeth. In reverse, the force is on all the teeth fairly evenly. In forward, there is greater force because there is greater load. Unless you are just going to drive it around at shows and not use it. Then it won't matter. As they are now, more force trying to press the bushings loose in forward. They are pressed into place in the links. So this is why the chain has a direction.

To better understand this stuff, there is a link for a PDF on all this in this post:

Thanks, I didn't think about the pressed in bushings. Makes sense now.

Hi,

I think it won't matter if you don't work it hard. And there are lots of things to bust on these old machines if you work them hard. If you are in softer dirt, then the pads act like shovels, as the tracks tend to spin. If you are on firmer dirt then there is more force into the bushings because the tracks don't spin.

I also think you will know if you need to flip them as you use it. I would flip the assembly though, not each pad, if it came down to it.

Unless.... I can't tell in the pic.... If the outer part of the bushings are worn quite a bit and they were flipped to make use of the other side. You know, rather than pressing them all out and turning them.

Thanks Lavoy and Stan
Since I first posted this I looked in the shop manual. The manual agrees with what Lavoy says about the shoes. It also shows the chains on the direction they are on now. Stan- thanks for the Dresser link very good info and answered some of my other questions.
The chains on it now are 60-70% I will leave them the way they are. I will put reversing the shoes on the “things I need to do” list.
I have looked at over a dozen dozers and excavators since my first post and the chains are all on the way mine are and the shoes are all opposite how mine are.
