2. Adjusting the V Rollers
The picture shows a 3 V Roller arrangement, Two of the rollers are fixed, just a bolt, round
spacers etc. holding the roller bearing.
Others have a nut for a spacer. This has the top and bottom holes offset from the centre so
that as the nut is turned the roller is moved into or away from the profile groove in which it
runs. This allows the pressure of the V pulley against the profile groove to be adjusted.
●
If there is play present, the rollers are too slack, rotate the offset nut to tighten the roller contact so removing the play.
●
If the rollers are too tight not only will they wear much faster but it can also cause sticking at various points along their travel.
To adjust
●
Make sure the profile groves and the surface of the V Rollers are clean.
● Slacken the bolt securing the adjustable roller slightly, if necessary.
●
Use the included spanner to rotate the hex spacer until the contact of the V rollers with the profile groove has minimal play but
is not too tight.
●
Retighten the bolt.
Re-check for play and re-adjust if necessary.
