drive pulley so that the tool lies squarely within the

31. Rotate the too so that it faces to the right side of the
hydro belt alignment_a
machine. Hook the end into the hydro pump drive
pulley on the front of the engine. There is a raised
contact area on the tool. Loosen the gearbox input
pulley and locate it so the outside of the pulley just
makes contact with the raised contact area of the
tool (Fig. 290). Since the distance between the
clutch sheaves and the hydro pump drive sheave
on the engine is fixed, the tool uses the hydro drive
sheave for reference for doing both belt alignment
procedures.
