Check & Adjust Injectors

I see in my service schedule that "Check & Adjust Injectors 24 Months".  This is not a service they perform in Nac. 

Do people actually need to do this service on a coach that gets maybe 15K miles in 24 months?

If so guess best place would be a Cummins coach care facility, any one have an east coast location you've been happy with? 

Guess I could have cummins do ALL my coach annual service this year and save a trip to texas


Thanks for the input

Chris,
 
Like you, we too saw that scheduled maintenance item in our book.  We were at a Cummins facility for another issue and asked them about this.  Now, bear in mind that ALL Cummins facilities exist to make money.  We were told that it was not necessary until something like 200,000 miles.  I am probably off on the 200,000 mile figure, but we are at 110,000 and the guy told us to save our money that it was way too early for us.

You do not want anyone touching your actual injector nozzles unless they know what they are doing.

Ft went crazy on their maintenance schedule. You should also have a book for your engine and if you look in there you will see it is somewhere in the 200-250K miles range.  THey have you changing the rear diff fluid every year or so too.  You do not have to adjust anything till the CUmmins book indicates you should start to look at it.

Generally with the Cummins L10/M11/ISM (All same family) engines, most users like to do the head adjustments
about every 250K and at 500K,  new bearing insers on crank and rods and keep going.
It appears very few Motor home users will ever have to worry about either.

I asked the local Cummins dealer support man, if I should do the valves at 50K just for good measure, he laughed big,
said it would be a waste of money, wait at least until 200K.

I had Cummins do a valve adjustment at 90,000 miles out of an abundance of caution as the PO put 80,000 miles I knew nothing about.  It turned out that there were minor adjustments needed, but nothing that would adversely impact performance.

Is this, "as the Previous Owner had put 80,000 miles on my FT that were not shown in the odometer?"

Paul,
 
No.  The speedo & tach I replaced (2003) after purchase as these were "blinking" the digital display for miles/hours.  And as the coach had a 6 month/6,000 mile warranty, I thought it prudent to have Foretravel of TN stand by the failure.

Thanks. But please do explain what you meant.
