Hi there, i would love to help
They are all about the same process to remove the walk belt, each one just has a few diff ways of doing it
You will need to remove the rear plastic roller covers, the front motor cover front and rear rollers and deck
you can sometimes get away with just taking the right side set of screws out of the deck and front roller and just lifting up and sliding the belt out, then back in
that should be your tread, its an exploded view it may be easier to see what you need to take off
if that was helpfull please hit accept and and leave feedback, if you have any other questions after you hit accept i can still help you on the same topic for no extra charge, thanks!
