    Existing belt snapped & no numbers on it.
    Measuring the inside of the belt it’s 690mm

    Purchased new belt & now fitted it.
    On this champion mower the adjuster is…..lift up grass flap & you then see a 10mm nut, washer, spring etc on the threaded rod which it fixed to the axle gearbox.

    After fitting this belt the 10mm nut is done up all the way.

    When I was fitting the new belt it was hard to get it over the pulley wheel on the axle gearbox but once over it then dropped down, came back a touch & then sat in the pulley groove.

    So my question is, Do I go bigger or smaller in the belt size so the 10mm nut isn’t done up all the way as currently I’ve used up all the adjustment now.

    I’m thinking smaller would make it even harder to get over the axle gearbox pulley wheel where longer would need more adjustment in the 10mm nut.
    I’ve been thinking about it now for a while & can’t decide which way to go.

    Obviously shorter - new belts are always a bit tight to fit and stretch in initial service. A Google search will likely help dig up the spec. for the original belt.

    Undo the tensioner completely, attach the belt, then retension.

    Make sure the tensioner is still connected to the gearbox - they often come off!
    You’ll be able to wind the new belt on if things are a little tight.
    You’ll probably get a replacement from GHS Ltd.

    I did undo tensioner completely.
    Actually the it’s were in the floor.

    It’s connected as I fitted new belt.

    Just puzzled me which way to go with the belt thanks.
