I have just repaired the pins in the selector forks and I am about to refit the quadrant there must be a trick to getting the selector pins in the quadrant groves and the selector shaft in the inner bearing bush while compressing the selection plunger obviously I suppose I could disturb the end cover for the shafts and remove the selector pin and spring but all is well there and I am reluctant to do that. Is there a particular position of the quadrant ? should I take the selector fork spindle out and fit it after the quadrant? or is there a simple tool to hold the selector plunger out?
