It’s important to bolt up your track group properly because an improper bolt up may result in your shoes coming loose, if they are not tightened immediately, they will flog out the bolt holes and make the shoes unusable as they will never stay tight again. You can also damage the chain if you use the shoes when loose for a long period of time resulting in the pins and bushes becoming loose in the rail.

Not to discourage you though, because when correctly done yourself, you can save a lot of money. So, all we recommend is following each step closely and if you are ever unsure about anything, please give us a call and we’d love to help out.

 

Tools you will need:

  1. Heavy-duty crowbar
  2. Wire cutters
  3. Grinder with around 36 grit sanding disks
  4. Impact Driver with the correct socket according to the size of the bolts
  5. Torque Wrench
  6. Lubricant
  7. All safety equipment required for the tools

 

Stage 1 | Unroll the Chain

  • First, begin by unrolling the chain.
  • Put the Master Pins aside.
  • Once this has been done it may have kinks in it, if so, you will need to flatten it out. (The reason you have to flatten it out is that when you come to sit the shoes on the chain the bolt holes won’t line up)

Stage 2 | Preparing the Chain

  • If the rail’s with the bolt holes are facing down, turn the chain over so that it’s sitting with the bolt holes facing up.
  • Sand the surface on which the shoes will sit on with a sanding disc preferably around 36 grit. See the picture below.

Stage 3 | Prepare the Shoes

  • Begin by placing the shoes upside down on the chain.
  • Sand off the paint, so that there is a clean metal strip where the chain will sit. (The objective of sanding, is to remove the paint so it is metal on metal)
  • Once all shoes have been sanded, flip them over and line up the holes, be sure the shoes are on around the right way. The edge with 2 lugs cut out go to the widest part of the chain link.

 

Bolt up using Final Torque Procedure – (If preferred check out, Bolt up using 1/3 Turn Torque Procedure’ below)

  • Start by oiling the bolts with lube spray, and put them through the holes
  • Install the nuts the correct way, (rounded corners to chain face) Then tighten the nuts on low air pressure or with a battery rattle gun.
  • Check the chart for the final torque setting and adjust the torque wrench accordingly.
  • Never tighten up one side first, always tighten to the number sequence shown in the picture below.

 

Bolt up using 1/3 Turn Torque Procedure

To make it easier to tighten the bolts accurately, paint or mark the outside of the socket with alternating white lines at every other corner of the Hex.

  • Tighten the bolts to the specified pre torque.
  • Give each bolt an additional 1/3 turn.
  • Do this in sequence as the chart below.
