Track Shoe nuts and Bolts

I got some ITR branded ones for the D9 $6.50AUD for the bolts and $3 for the nuts. I did them up to the tourqe spec in the book, can't recall the number but i had a 6ft pipe on the breaker bar and it took a bit of effort

Use some fine thread grade 8 bolts and flat washers/ Teflon lock nuts.

Hi Team,
yes, worn bolts and holes will allow track plates to re-loosen, BUT by removing the plates from the chains and cleaning the mating surfaces to shiny bright metal finishes will allow friction to help keep the plates from moving again.
Rust and dirt on the clamping faces will allow easy movement--picture a poor lubricant.

We always removed the paint from new track chain and track plate mounting faces to prevent loosening on new track components.
Paint, dirt, rust, mill scale, etc. between such hard working clamped metal faces will almost be guaranteed to come loose--especially if working in rock.

Cheers,
Eddie B.

U can use the crappy bolts but sounds like you are going to have to weld in place now .

get at least grade 8 bolts and torque to around 250 ft lbs---and as edy said clean the surfaces real good

Maybe I'll try to tighten them up quite a bit more than I had done. Sounds like I could just not have tightened them enough for them to really hold.

If the growers are worn down they tend to loosen the bolts

Unless I mis-read, you did not tighten the two rusted ones?
Takes all four to hold the pad on!
Double nut or do as Rome suggested. 👍

Hey, I have a pad or maybe a few that only have 3 bolts and they stay fine. 😛

Technically, according to geometry or maybe physics too, only 3 bolts are necessary.

It'll be quite a task tightening the rusted ones, I think. I once tried to loosen a track bolt and it just laughed at me.
