RY4CPH Ryobi Trimmer - Instructions

Removed the 2 bolts holding the gear head to shaft. On my model I had to remove the complete trimmer head, then using 2 wrench take the trimmer head adapter off the gear heD. One video showed simply putting a screwdriver in the notch behind trimmer head and unscrewing complete head. Mine of course was slightly more involved but still quite easy once I saw what needed to be done.

Remove air cleaner cover and filter, remove air box base (2 bolts). Simply reverse order to reinstall. Side notes: 1) The air box itself comes complete with a new filter, so no need to order that separately unless you want some spares. They're only $0.86 each anyway, so you might as well while you're at it. 2) Part was perfect in fit and function. 3) The prices here are so ridiculously low, I don't know how they make any money. I'll most definitely be back!

Remove carb cover, remove 2 t25 torx head screws. ( they are loctite in so they may be difficult). flip up carb, install new carb. swap gas fill and return lines to carb. choke and start, go to work.
