Cat C-7 belt replacement

Do you access the belt for replacement through the closet in the bedroom?

Yes. Our closet floor had 4 or 6 large flat head, course thread screws to remove, but I also found some drywall screws in the corners. Not sure why they needed both types, but I did put them back in. I think you will need a 1/2" large break over bar to move the tension idler over to get the belt installed. Possibly a 1/2" ratchet with a pipe to extend the handle will work also.

There are 2 belts on your unit...The serpentine belt is a Freightliner part and runs everything except the water pump...The water pump belt is V belt and a Cat part...On my mh I can access the serpentine belt from the top and the water pump belt from the bottom...This is assuming that you have a rear radiator rig...It is tight but doable...

I can buy both the water and serpentine belts from Freightliner.
And I can do both belts from top on my rig.
It helps if you have a 1/2 deep socket and a Off-set Box wrench for the water pump idler.
The spring tension pulley, is required to be swung away. Use a 5/8 wrench/socket to loosen the main bolt. There is no need to remove the bolt.

Well Sir,
To be able to give you a more accurate answer, we'd need to know the coach/year/model/etc. That would give people that have the same coach, the ability to tell you what you're up against. The C-7 was placed in many years/makes/models of coach which, all have different access capabilities.

On our coach, an '04 Itasca Horizon, 36GD with the C-7 330HP CAT, I replaced the belt(s) when I pulled the radiator for some other maintenance. That made it way easy but, pulling the radiator was not a ton of fun. But, I do all my own maintenance anyways so, it was par for me.

Sorry about the minimal information on my MH. I use the Forum constantly for reference on work I'm doing on my rig but seldom need to ask a question that hasn't already been answered. I'll add the info to my signature. I own a 2006 Fleetwood Providence with the Freightliner chassis and the Cat C-7 350HP.
Thanks for all the info. I think I'm ready.

Thank you Sir for adding pertinent info on your coach. It's just one of those things that helps when and if, any questions are asked. Without knowing your particular coach and, it's bedroom layout, it's hard really advise on how hard it's going to be to access the front of the engine, to gain access to the serpentine or, water pump belt. Not many folks would pull the radiator to do the belt and or, any other maintenance on the front of that engine but, I would.

I know, 'cause I've already done it. And, knowing what I know, the job would go about at least twice as fast as it did the first time. But, while the engine access (at least the top side of it) is fair on our coach, trying to change that belt and any other maintenance from hanging over the engine, would be pretty darn tuff for me. Anyway, below is a pic or two of how your engine looks, without the radiator and CAC in the way.

Just did this a couple of hours ago today, and it took two of us to get it done since neither of us had an idea. We found if you push the belt in between the blades then work them back out there is enough room for the belt to pass between the blades and fan shroud, then run the belt as normal. This is a pure pain to do but can be done. just ask Paul's Roadside Service!
