reversing tracks to extend life on a D4 ????

No, you need to have the pins and bushings turned. This will make up for internal wear and give a new outer bushing surface for the sprocket.

thanks bob .

this is for farm use, and not much at that.
not or put back to everyday use.


what sort of pressure do you think i will need to press out the pins and bushings.
has anyone made their own press for this.?
i have a decent lathe and mill, making something does not bother me.
i have a couple of 30 t bottle jacks sitting there.
that or i could use the dozer or one of the tractors hydraulic pump to drive a ram.

If the bushings have been turned once, then you ned new pins and bushings, do yourself a favor and take it to a track shop, or find a better used set.

Putting the tracks on the other way round will wear the bushes, and sprockets, much faster, measure how much 'stretch' you have to see how much life is left in those chains, as it will dictate how much longer they will last before destroying the sprockets, which is expensive, then decide when to buy new or some good used chains.

In previous threads on "Pin Pressing", it pretty looks like 100 tons which when the move, they come out like missiles.
I would be leery of building a press.
My 2 Cents,

My dad rebuilt the tracks on his D4 30 years ago using a Hein Werner Porta-Power. He used the King-pin press attachment which was basically a large C-Clamp. His unit has 10 tons press and 6 tons of pull. This worked great when it came to pulling the master link pin, he just screwed a bolt into pull the plug out and ended up with the entire pin. At that time he was turning the pins and bushings on a set of rails he had purchased because his were completely trashed.

Must have been some loose fitting pins to get by with 10 ton on the D4.
I get by with 30-ton (just barely) on the D4 but if the pin ends are smeared from rubbing on the guards I have to get out the 60 ton cylinder. Don't think I'd build a press with less than 100 ton capacity if your doing a variety of track.
