I have a wonderful old Riccar 2600. It is clunking and not shifting. The repair shop I took it to said they cannot repair it. The top Gear is cracked and they can't get one. The bottom belt is also cracked in several places (I haven't used it for about 5 years), however they can get that. I temporarily don't have the manual and need the name and or number of the top gear (over the right side of the machine) so I can look online. Thank you.
