Cummins 8.3 Servicing question

New rv guy here...what can i expect to replace during a "Full Service" besides the obvious, oil, filter, airfilter, water seperator, any worn belts and hoses...and what is a fair price for the service? Looking at an older Monaco Windsor with the 8.3/3000.
Thanks, in advance for any advise!

Air ride/brakes?
Air dryer canister should be replaced.

No idea in reasonable cost, as I do my own servicing.

Anytime the main accessory drive belt is changed the belt tensioner should also be replaced.

So much depends on where you get it serviced. I have found a Over The Road trucking service company near me does good work at a fair price compared to a Freightliner dealer. When you say full service are you also looking to get the chassis greased?

What about the generator? Has it been serviced?

Cost? I would check with several places to get estimates. On my coach, with me performing the labor, I would guess parts alone (engine, air system, generator) for everything is probably around $300.

Cost will vary widely depending on who you use:


The list will look something like this:


-C8.3 oil and filter change (use the newer LF9009 oil filter) annually



-SCA check and Water Filter change if needed (every six months)



-Both Fuel Filters changed (annually)



-Complete chassis lube including drive shaft slip-joint, slack adjusters and steering box (annually)



-Air filter change(every 2-3 years)


-Generator Oil, Oil filter and air filter change (annually)


-Generator Fuel Filter Change (every 500 hours)


-Air system dessicant filter change (every 3 years)


-Allison transmission fluid and filter change (every 3 years or so)


All services listed before the air filter change plus the annual Generator service can be done by Speedco for less than $300. All other items will be subject to a wide variety of prices depending upon the shop.

You may also want to submit an oil sample to a lab for analysis. It can identify problems that may be developing but show no symptoms. Like dusting.

Don't go light on the air cleaner. The PO of our coach relied on the vacuum gauge alone, BAD IDEA!! The air cleaner was almost 10 yrs old!



After dropping $26K into an engine swap due to a dusted engine, that $175 air cleaner doesn't sound too expensive to change often!



Why did I buy a coach with a 10 yr old air cleaner? Well, as they say, you don't know what you don't know. If I knew then what I know now, I'd have walked away. Quickly. We do like the coach a lot and have added 11,000 miles in our 1st year.



Live 'n learn. Expensive education!


Our recent full service cost ~$1600
  • Oil/filter change, main & gen
  • Fuel filters all
  • Air cleaner
  • Trans service- fluid/filter
  • Air dryer
  • Chassis lube

cost of regular service

We purchased our coach in February this year with 42,000 mikes on it. I had zero knowledge of any prior maintenance that had been done, so I took it to a heavy truck shop, Neely-Coble, Nashville, TN. I asked if they could look everything over for me along with changing oil and filter, both fuel filters, air system filter, chassis lube, complete service of the generator which included oil filter fuel filter air filter etc. The shop suggested that i allow them to do a DOT inspection( something I believe they do on the big trucks). They did check the anti-freeze coolant to verify it was still in good condition and all was well. The only problem I had was a leaking power steering hose at the steering box, I thought they may need to replace 40 feet of hose but as it turned out, it was the low pressure return line. Luckly they had some slack so they trimmed off 3 " and buttoned it up. All this ran about $1500.00-expensive to me because I normally do all my own maintenance on cars, but I wanted to establish a baseline for maintenance and have knowledgeable mechanics inspect to make sure we are safe and to also protect the coach. These forums are essential in gaining the knowledge you need to keep everything functioning as it should-thanks to everyone that contributes!

Consider an annual day trip down to Red Bay, AL. The diesel shops are great and are about half the price of the Neely Coble quote I got recently in Huntsville.

If you're on a Freightliner chassis, they have maintenance listings based on mileage/time. Give them a call at 800.ftl-help.
