How did the coach run going to the rally? Did this just happen on your return route?

I called and talked to Ken about this a few hours ago.  They had stopped for the night.  Ken said he can keep it from overheating if he keeps it under 58 MPH.

I really had no help for him.  Their coach wiring is not like a regular Dina as their coach has been rewired to all 12 volt with no 24 volt remaining.  I saw their fan clutch at Arcadia and it sures looks identical to mine.  From the wiring diagram for my coach I think the clutch might be 24 volt, but not sure without actually checking mine.

I can't see any place on the Dina clutch to put in a bolt, but I could be missing something.  The maintenance manual doesn't say anything about a bolt.

I'll check ours tomorrow and tell ya where the bolt is/goes! (it's sorta hidden from the back side if I remember right!)
I hope it's something simple, but if your luck id like mine it won't be.

I still suspect the incoming air supply.  (Brian remember yours had similar overheating problems from the bird nests in you intake?)

I'm with BK - restricted intake - richer mixture - unburned fuel - Do you have any tell tale exhaust? Can you see it if you do?

Ken replaced the original Dina air intake with something new.  He could still have an obstruction, but not in the usual place for a Dina.  He said it was running fine the first part of his trip.

I do see where a bolt could possibly be installed to lock up the clutch after I looked closer at it.

Brian,
I know Ken replaced the original air intake. IIRC the "tailpipe" on the right is for the air intake. If the "tailpipe" is the ONLY place the filter draws air from, it is highly possible that it is too restrictive.
Again IIRC most stock intake ducts/pipes/hoses/etc. are 8-10" in diameter. Those pipes coming out of Ken & Ruthi's appear to be standard 4-5" stacks. An engine has to be able to breath to run properly.

I'm not saying that it is definitely the issue here. As I really don't know and can't tell just from pics.

But (again) IIRC it took some convincing on my part for you to believe that yours could be blocked the way it was, or that it could cause yours to run warm also.
(I ain't always right once I thought I was wrong, but it turned out I was mistaken! Grin)

There are numerous other possibilities that could be Ken & Ruthi's problem, and in time we will be able to help them diagnose and fix the problem. I just like to look @ the most common areas I personally have experienced first.

BK, Ken stopped and opened up the intake to see if that was a problem, it still heated up. Think it is a clutch problem. Can you describe to us where to find the place to lock it up? Thanks

Ruthi, most of the Dina's your year model had a switch to turn the fan off and on have Ken check and be sure the switch is on if he has one some were controlled by electric over air also 


good luck

Ruthi,
On the back side of the fan/clutch assembly (radiator side) there will be some holes and if you spin the fan you should see where at least two holes will line up. Take the appropriate size bolt and thread it in and snug it up!

Now that said, there is a way to see if the clutch is working at all on a DINA that many buses do not have the option of!
If the rear switch panel is original, you can turn your battery power on (leave ign switch off) and flip it to rear start. You should hear a "clunk" or loud "thud" as the solenoid kicks in to engage the clutch. Once you hear this you should not be able to turn the fan! (unless it is slipping in the clutch or on the belts!)
Let me know if you need more details. I will go down soon and verify the bolt locations and bolt size on ours right after eating brunch which is being cooked right now!

Thanks BK. We are 45 min from home, so, Ken will call you when we get home and have the tools to work with.

I hear that clunk when I turn my switch to rear.  I unhooked the clutch connection to measure the voltage this morning and now it doesn't lock up when I turn the switch to rear, but the clutch still makes noise and it is still cooling fine.  Ken and Ruth's bus has been completely rewired to 12 volt and I wouldn't be surprised if the rear start is gone.

My air intake originally was blocked, but not totally.  It was one of the first things I thought of when I was overheating.  I pulled the elbow off the air filter and it still overheated.  My overheating was fixed with a new radiator core.

Ken and Ruthi, given your intake plumbing, I would install a vacuum "tattletale" before the turbo and see if it is pulling more "vacuum" that it should.  They are cheap and easy to install (if you have a threaded port).  For sure, that would tell you if you have a restriction. 

If I picture your route correctly, you do not  have all that many hills between Arcadia and your home.  If that is the case, then air restriction would not be an issue.  The  only time you need big flow is when you have to be heavy on the throttle.  Then you can always back off and see what happens. 

You have a DDEC and I would think it would adjust for the lack of air by cutting back on the fuel. 

My bet is the fan clutch.

Random thoughts.

Ruthi, I want you to understand how sincere I am when I tell you this.  I want to offer to you and Ken the use of your old bus until Ken can get the new one where he feels comfortable.  What I am saying is, I know that your running out of time to get back on the road with your work.  I have the old girl fueled up in my shop ready to hit the road.  If Ken wants to fly to Tulsa, I will pick him up and take him to the bus and he can drive it back to your house and use it on the road working until he can get back to the new one.  I would not do this for anyone but you two.  You two were nice to me, when I flew down to buy your bus, that   I wanted to offer the same back to you and Ken.  I trust you guys.  I know how well you take care of things.  Sincerely,   Aaron Veale
