Hi Charlie
if you gave the shop the correct model number for your machine they will have given you the right belt,
Greenfield have always put the part numbers for belts and blades on the body of the machine, so if you give the right info it will be the right bit.
if you have the same carrier as SD has shown, then that carrier will slide to the rear for belt tension, make sure you put the belt on EXACTLY as the old one came off, should be no problem!
