Some of you may have noticed some hesitation of the dist. moving pin to pin . This could be be a sign of worn out dist. tubes. (070-006-004) a good solution is to flip the 2 tubes with each other left to right and right to left, you will see different wear spots on each one so you can get a lot of years more use before buying new tubes. It wouldn't hurt to have a couple of spare tubes in case you run into bent ones. If you have a habit of bending tubes Stahl's makes a super tough tube that wont get bent.
To switch tubes remove the dist. belt, remove the adjusting rod at the upper end , remove the 4 roll pins at the back of the tubes. Sometimes a plastic mallet is needed to seperate the tubes from the carriage. slide the tube assemby out of the rollers that way you won't have to readjust them. Take the assembly to the shop to finish swapping the tubes. Before knocking out the front roll pins put a block of wood under the front carriage so the trip arms don't get bent or the tubes don't get bent.
