Hey Dave, I've Got a Problem / Re: Broke down in Caldwell, KS with 9 dogs!
« Last post by David.e.atherton on October 08, 2018, 01:30:33 PM »
Hi welcome , MAYBE I can help you but you have a Caterpillar C-9S engine and your
Problem will be located within the regeneration system and many questions pertaining
what is going on is something diagnostic read out will only be able lead us into the problem
area. You have Foley Caterpillar that bought out Martin caterpillar so they have several service shops close by you. More than likely problem is within what’s called the ARD head that
allows the regeneration to cycle. If anything goes on within the regen system your engine will derate and will not allow you to start. Try at all possible to have a Caterpillar Dealer work
on your system and not a truck shop. Once you get a Caterpillar ET readout and print out
on what has taken place and email me copy than I can give direction. One thing Do Not
Sign Anything until we can review what is happening, and tell them want them to talk with your mechanic which is the Diesel Club Form team. Ask Dave, Dave Atherton Retired Cat Mechanic

Gentleman we all have good points on components replacement or not to replace until
Components fail. There are many of motorhome people carry extra parts with just in
case of failure. The down side to all of this how can we replace failed part on the road.
Another way to look at this picture, removing radiator and charged air cooler for service
and at that time replace fan belts , water pump, idler pulley, fan bearings etc. keep the
old parts for spares being they still work but lot of hours of operations. Owner can relax
and still carry the parts removed . Many ways to look at cases like this and again myself
Few extra dollars now at labor paid to remove radiator and charge air cooler person can
relax on the road being towed to unknown service and start over removing components
you just had off 5 months ago.

I don't think there is any set rule on when to replace components with a few exceptions. I have replaced water pumps and alternators with as little as 1000 hours and 35,000 miles and there is a lot of equipment out there with countless hours and miles on those components so I think it comes down to the circumstances involved. It your digging in to get to take care of one problem and the cost saved to replace a few common fail components is sensible but not a guarantee that you wouldn't have to go in to replace again a short time down the road.

Question. Are you changing out your alternator and water pump just because you have the radiator out or is something wrong with them?  How long does these two items normally last?
Mine are 11 years old,should I be thinking of changing them out?
There is nothing wrong with the alternator, or water pump. Likewise, nothing wrong with the fan bearing, or idler pulleys. The motorhome has 114,000 miles and is 13.5 years old. Access to many of these components is difficult with the radiator in place. It is all pretty simple now. I do all of my own work, and have an aversion to being broken down. That almost never happens, as I try to take excellent care of my equipment. My motorhome has been in a shop exactly one time. That was for a repair under warranty, which was actually a pretty simple repair. I have heard and read of all of these components breaking or wearing out in much less time and mileage than I have accrued. Sometimes with disastrous or at least expensive consequences. Likewise, I am sure that many of these components last considerably longer. It is a matter of comfort level, I guess. I have the ability to do the work, but I prefer to do it in the comfort of my own garage, rather than on the side of the road. I am sure a lot of people think it is foolish to replace still functional parts. And, MOST people probably wait until a part fails to replace it. I am not saying that is wrong, but it may not be economical or convenient.

Whether YOU should replace your water pump or alternator is not something I am able to advise on, other than to explain my rationale.

Captpar, Brett is correct the point is that they are there and cost to change out major component
Is very good business. The old saying if not broke don’t fix it  but figure today’s labor cost it is
extremely cost effective to change out major cost items like you have done so.

Captpar,

A reasonably complex issue. 

Basically, if you have to PAY RETAIL for labor, AND they are fair with charges, if components are over a decade old, probably makes sense to replace them as labor charge should be minimal once there is complete access to the engine.

Yes, that is several different questions.
