barclay Report post Posted April 9, 2023 Hi All, Happy Easter. rebuilding a 345 and have the pressure bar out. Now how do I get all those pesky ball bearings back in the sleeve inside the guide bushing? Is there a trick? barclay Quote Share this post Link to post Share on other sites
1hp Report post Posted April 9, 2023 have you tried holding them in there with grease? Quote Share this post Link to post Share on other sites
barclay Report post Posted April 9, 2023 Have not tried anything yet, but grease would be my first choice, working my way down or up from the bottom so I don't lose the buggers. I think i will try your idea and see how it goes. Should I paint the head or leave it original? Quote Share this post Link to post Share on other sites

Another tip I saw a couple days ago is to put a rare earth magnet next to where you are removing or replacing small items like c-clips, screws, etc. so if you drop them, the magnet will grab them saving you from searching all over the floor and benches or furniture where they like to hide.

barclay Report post Posted April 12, 2023 I think i am not going to paint it, keep it original with the original decals, one from Willcox and Gibbs sales and service. So putting it back together. Quote Share this post Link to post Share on other sites

The part number is 91-087951-75/995, costs about $20 US and is a part of the Arm Parts. This type of bracket is also used on other PFAFF machines like the PFAFF 337 to mount such things as needle positioner, speed synchronizer. The video at 0.24 shows such an installation ( www.youtube.com/watch?v=SateU14ZlKI ). kgg Quote Share this post Link to post Share on other sites
jannickz Report post Posted March 5 (edited) Unfortunately, reassembling the pressure bar with the Ultra high-speed angular contact ball bearings inside the guide bushing on a 345 can be a tricky and fiddly process without a specific tool or technique. If the ball bearings are magnetic, use a strong magnet to carefully guide them one by one into the sleeve through the opening in the guide bushing. Be patient and precise with your movements.
