Hints & tips


Fitting a new hinge or HT Joiner
Fitting a new K-Type Joiner
Accurately measuring important dimensions on a web
Fitting Instructions
Fitting a new hinge or HT Joiner
Cut through the end of the hinge
Remove the old hinges by drilling through the rivets
Fit new hinge over belting, making sure that the holes line up with the original rivet holes
Tighten rivets so that the back edge of the hinge nips to the belt
Fitting a new K-Type Joiner
Remove the bolts holding the hinges with 10mm and 13mm socket spanners
Fit the new hinge over the bar end holes and the existing belt holes
Tighten bolts through the belting into the threaded back plate to obtain a good grip on the belt
Grind excessive bolt thread flush with the backing plate
Accurately measuring important dimensions on a web
Pitch:
Place tape measure from centre of first bar to centre of the 11th bar thus creating 10 spaces. The pitch measurement is then taken from the whole distance divisible by ten. I.e. if the distance from centre of first bar to centre of 11th bar is 400mm then the web pitch is 40mm.


Finding the width of the web:
Can be done by simply taking the full width from the outside of the belting, however for spare joiners or better accuracy, the following measurements are useful:
Width of belting
Distance centre to centre between the outside hole centres
Distance between outside whole centres:
Measure centre to centre of the hole centres on a section of the outside belt
Thickness of Belting
Measure the thickness of belting at the thickest point on the tooth
