Mantle, concave, jaw plates and blow bars for Terex Pegson 1000, 1300 and 1550 Maxtrak, Premiertrak 400 and 600, and XR400.
Maxtrak cone machines and Premiertrak jaw machines, six models. These are contractor plants: they move between sites, they run hard, and they are usually maintained by the operator rather than in a workshop.
That single fact changes what a good wear part is on this brand.
On a machine that is maintained on a site with a telehandler and no machine shop, a liner that needs less fitting wins even at a higher price. We ask who changes the parts and with what equipment before recommending a profile, because the cheapest casting is not the cheapest change if it needs work to seat.
A Maxtrak cone is usually run as a secondary behind the jaw on the same chassis train, so its feed is consistent and its liners wear predictably. A Premiertrak sees whatever the breaker produced, including oversize, and its plates wear asymmetrically. Reading those two wear patterns is a different job and we ask different questions for each.
Wear concentrated on one side of the circumference means the feed conveyor is not centred, which on a tracked machine is often a belt tracking issue rather than a chamber issue. Replacing the liner without correcting the belt reproduces the pattern. We ask for a photograph of the worn part and, on repeat orders, whether the belt has been re-set.

1000, 1300 and 1550 Maxtrak, Premiertrak 400 and 600, and XR400, listed with parts in the table above.
Yes. It is a smaller frame than the Premiertrak 400 and the plates do not interchange, so we confirm which machine you have rather than assume from the name.
We can quote to the drawing so it goes straight in. Tell us it is a field change and we will say plainly if the casting we are proposing needs anything beyond lifting it into place.
