Genny drive belt

[stink]

I have an onan cummins 7.5 kw genny in my mh. It's not on a slide. Anybody know how to get to the water pump belt on this genny without removing genny from mh? Unit has 2200 hrs and I don't think prev owners bothered with the belt.

Unfortunately you need access from at least 1 side and the top to change the accessory belt. There is no tensioner so you need to unbolt the pulley to get the new belt on.

Accessing the rear end panel is a must to replace the belt. I would highly recommend pulling the genset and doing a complete belt, hoses, thermostat (& gasket), water pump replacement and change all filters and fluids. Bench test and check valves for proper lash clearances; they may need adjusting if never done before. Good luck and keep us posted.
