"It's the little room that can ruin a final! My expert advice: as you must remove the rear axis to pass this belt, do not do the work half way. Take the opportunity to inspect your shaft bearings and locks.
A little mechanic secret: always go up two belts on the axis at the same time, even if you only use one. Attach the second "waiting" to the frame with a small Rilsan necklace or tape. If the first break in the middle of the race, you won't need to pull out the complete axis to repair. You cut the break, you free the reserve, and you go back in 2 minutes! Also check the alignment of pulleys: a jumping belt is often the sign of a water pump poorly aligned with the shaft."
