There are three types of belts used in a Mark5/V headstock.
The motor belt(connects the motor pulley[floating sheave and fan sheave pair] on the motor shaft to the idler pulley[idler sheave and control sheave]) is a special length(25.5") belt that is slightly wider than a 1/2"(4L) 38° "V" belt.
The idler shaft and main drive shaft have either a Gilmer pulley or a Poly-v pulley.
The Gilmer belt is a cogged belt similar to an automotive timing belt.
The Poly-v belt is as the name implies and is essentially multiple mini v-belts side by side. An automotive 'serpentine' belt is an example.
All three are 'drive belts'.
The Mark7 / Power pro headstock drive belts consist of a poly-v belt connecting a pulley on the motor shaft to the idler shaft and a second poly-v belt that connects the idler shaft to the drive sleeve.

[/quote] Wait, db5, you replaced the drive belt with the link belt or did you actually replace the poly V belt with the link belt?[/quote]
Mia culpa. Thanks for the correction. I replaced the drive belt.
