Jura Capresso-Impressa C5-C9-E8-E9-F7-F8-F9 Brew Group Drive Shaft
The Drive Shaft, or Brew Group Guide (Part #841),provides the connection of the Gear Motor to the Brew Group. The Gear on the Gear Motor engages with the Brew Group Guide during the brew process, causing the Brew Group infuser to rise, compacting the coffee into "puck" form. The teeth on the Gear of the motor and the Brew Group Guide can become worn over time. If you are experiencing problems during this process, check these two vital parts first.
