Installation (User Guide)
Couplemate 65mm Round U-Bolt Kits make trailer spring maintenance easy.
- Place a U-shaped curve over the axle beam.
- Align the centre spring bolt and U-bolt legs with the fish plate holes.
- Secure the fish plate to the leaf spring through the supplied washers and Nyloc nuts. Tighten nuts to 100Nm with a socket.
Important: Check U-bolts and re-tighten nuts after the first trip and every 250 km thereafter.
Safety Precautions
Do not re-use Nyloc nuts. Nyloc nuts are often less effective after the first use. This is because the nylon material (the key component of a Nyloc nut) has already once conformed to the thread profile.
Do not use a rattle gun to tighten. Rattle guns often tighten u-bolts too fast, too tight, and unevenly. This can cause nylon to overheat and risk undue wear.
Ensure the axle has welded axle pads. If not, use the axle pads supplied with the spring U-bolt kit.
