How do I change the spring pins?

The spring pins are made to snap if, for instance, something is caught in between the shovels and the drum. This way, the drum and gears last a lot longer.

You can purchase a complete spring pin set at your local SoRoTo® dealership.

The set includes:

• 4 pcs. spring pins (consists of 12 smaller parts)

• Drill guide

• 3 pcs. drills

• 1 pc. rubber top

Other than that you need:

• Angle grinder

• Hammer

• Drill

How to change the spring pins:

1. First remove the broken spring pin(s). This is done with a angle grinder leveled with the axel. (Pic. 2). BEWARE: Make sure you leave one spring pin in, to lower the drill guide over.

2. Lower the drill guide over a single spring pin and the axel. (Pic. 3-4).

3. Drill new holes for the spring pins (they need new holes; do not try and drill the old pins out). Start with the 4 mm drill and then use the 8,1 mm drill (Pic. 5-6).

4. Hammer the spring pins in as shown on pic. 7. Start with the largest part.

5. Now you're ready to lower the mixing system over your axel with the new spring pins, and return to work.

The 10 mm. drill and rubber top is for drilling holes in old mixing arms that were made with only 2 holes for spring pins.
