Hi. I'm new to this forum and live in UK. I'm restoring an old (1990) Morrison and have to replace the double sprocket that drives the reel (or cylinder as we call it over here).
I sourced a spare from Spares in Australia (cheaper than buying it here even with shipping). Unfortunately, when it arrived, although it looked identical to the one I was replacing, it did not screw onto the shaft properly. After a couple of turns it got very stiff. Initially, I wondered if the thread pitch had changed between 1990 and now but the part number I ordered is the same as shown on the "old Morrison" parts list I downloaded from this Forum.
I therefore believe the replacement part has a defective thread. Before contacting spares supplier I would welcome any comments - particularly on the possibility of the thread specification being changed. I have emailed Masport with the same question but previous experience is they have limited information on these older machines.
Thanks.
