A PK36 - M8 set for the smooth passage
The PK36 - M8 smooth roll triple set is prepared for the smooth passage of roller mills that combine a 36-rib PK belt with an 8 mm-pitch (M8) timing element. On a smooth passage the roll speed differential is low, and keeping that ratio constant throughout the day keeps flour fineness and sifter loads balanced.
The right order for fitting a timing belt
- Isolate the mill and release the tensioner.
- Remove the old belt; clean the pulley teeth and grooves with a wire brush.
- Check the pulley teeth for wear, burrs or breaks.
- Fit the new belt so the teeth fully engage, without forcing it. Never “walk” a timing belt on over the pulley flange; this damages the internal cords.
- Set the tension, turn the mill a few revolutions by hand and confirm the belt stays centred on the pulleys.
Why tension matters
A timing belt does not slip, so it does not need as much tension as a ribbed belt. A slack belt can jump teeth and momentarily upset the ratio; an over-tight belt strains the bearings, whines and shortens belt life. Staying at the belt maker’s recommended value is best.
Pulley checklist
- Are the timing pulley tooth flanks polished or thinned?
- Are the belt flanges (side discs) bent?
- Are the groove edges of the ribbed pulley rounded?
If any of these apply, renewing the set is recommended. Altınbaşak supplies the PK36 - M8 smooth roll set to suit your mill model, complete with bushes.
