MC8
« on: November 12, 2008, 06:16:47 PM »

I have been looking at 2 different MC8s to buy for a conversion. I had them both go into the shop (detroit diesel/ allison)


This is what they found:
MC8 #1:
right front clearance light not working
right side front turn signal not working
coolant at +10F and needs to be replaced
many engine oil leaks
Trans leaks at filter head, cooler fittings leak (all 4)
trans dipstick tube at the pan leaks (needs brazed) and output flange leak
power steering has a leak
lots of oil comming out of the air dryer (mans the compressor needs to be replaced)
pinion seal and gasket leak at the diff




MC8 #2
Front axle wheel seal needs to be replaced. (oil is contaminated with water)
replace air dryer cartridge and purge kit (water in air system)
Front and rear trailing arm bushings warn
reseal rear pinion seal leaking
replace rear drive axle fluid
air compressor feed line leaking air
engine blower motor bushings are warn
radiator showing signs of leaking
engine oil leaks
trans service harsh shifts 1-2
power steering leak at tras area
tune up air filter


Please let me know what here is REALLY bad. Thanks.

I own an MC8 and if I had to choose I would take the first one.

Replacing the compressor is not a bad or expensive job.

I'm not sure how much of a problem the pinion seal is.

OIL LEAKS it's a detroit. I have been told if you paint an anvil detroit green it will leak oil -- they can be fixed but you have to really want to fix them.

Before I would buy it I would get an infrared thermometer and when it is up to operating temp check both radiators at multiple locations to be sure that there are no blocked tubes and the cooling system is up to speed.

That was the single biggest problem I had was overheating but I live in the southwest and at altitude.

Just my opinion and you know how those are.

YMMV

I will save somebody some typing, and state the obvious. Also a lot depends on the price.

#1

"""right front clearance light not working"""      No big deal

right side front turn signal not working"""         No big deal

coolant at +10F and needs to be replaced"""    No big deal

"""many engine oil leaks"""   Might not be a big deal... Depending on where they are from. A lot of them just take a little maintenance.

Trans leaks at filter head, cooler fittings leak (all 4)""" I'm not sure, sounds a little worse...

""""trans dipstick tube at the pan leaks (needs brazed) and output flange leak
power steering has a leak
lots of oil comming out of the air dryer (mans the compressor needs to be replaced)""" Routine mantinence
pinion seal and gasket leak at the diff"""         Some of these issues might be a little more major. Biggest thing is how mechanical are you? If you need a shop to do all of these it might be in a different category.


 
Bus #2

I don't have time for... Right now. Grin Grin Grin By morning, if nobody else responds, I will finish up. I just didn't want to lose this part.

God bless,

John

Unless they are free, I'd run from both. 
Both are bad sick.   No one issue is show-stopping, but the list is going to get expensive to repair.
Be especially wary of pinion seals leaking.  You may have more than a seal failing.  Pinion bearing failure cost more than the bus is worth to repair. 
Same thing with radiators.  Cost big. 
Too many issues on those coaches.   
There are a good many decent coaches to choose from if you'll look around a little.
A good 2 stroke won't leak much oil.   All those oil leaks indicate a total lack of maintenance. 
Be careful!  JR

It all depends on the price point.

MC8 shell or seated coach are pretty much done, value wise.

Nothing above scrap value unless the coach is lovely and ready to roll.

And I have an '8 and a parts bus too.....

happy coaching!

Good idea, having somebody look at them. Personally, for number one to be right, the price would have to be great. You might want the shop to quote getting those issues fixed. You will also want to decide how much you want to spend getting it going. You might find a steal of a deal, sometime, but usually you pay for what you get. Even with our 95 DL3 (MCI) we have sunk a busload of money, to get it into pretty reasonable condition (We did a lot of the work ourselves (parts are expensive), since our DD and Allison shop is too expensive. I think that its up to $135 an hour now!!!).

That's my .000002, and JMHO.

I think you should tell us the two main parts to your Delmer,

1) How much are they asking for each coach?
2) Can or are you willing to work on your bus yourself?
3) What part of the country are you from.

John, I will do the normal, and state the obvious (which I am really good at) Grin Grin Grin. I think that he is from Oregon. Not that I know this as a fact, but I will go out on a limb and make this assumption Wink Grin Grin. The other questions I'm not sure on.

God bless,

John

How expensive are these to fix from the first bus?


The first one shakes A LOT in the back when not in fast idle. Is this ok?

Waaaaaayyyy high!  Run screaming in the opposite direction!  Just take a good long look at the e-place under "buses" and see how many have no bids.  The bottom fell out of the bus market at about the same time the housing market tanked.  For 10K, you can end up with a nice finished conversion and modify it to suit your needs.  I'm glad to hear you took them to be inspected.  Keep looking.  There are plenty out there with desperate sellers!

Here is a big list with some MC-8's even.  I think its a bit dated but the prices are about right if the buses are represented correctly. http://frontlinebuses.com/a5-8.pdf
