MX6 & MX6 Elite Pool Cleaner Pulley Drive Assembly.
Zodiac combined the older style Drive Pulley R0595100 and the Engine Coupler w/Shaft R0567100 into one item, this R0595101 MX6 & MX6 Elite Pool Cleaner Pulley Drive Assembly.
So again, this item R0595101 consists of both R0595100 and R0567100.
The drive pulley coupler has been updated. It now enables you to connect it to the engine coupler w/ shaft, which also connects to a bearing, enabling it to rotate with ease. It sits in between the middle engine housing and the lower engine housing.
