Could be a few things
There is a spring that holds the difflock out with no air (should not stay in)
My Mack starts to clunk going down hill in low
Usualy it tells me that one set of tyres is getting a bit low.
The Mack rear end likes to have all the same size tyres.....Mark

The value liners here in OZ only had 1 aircleaner on the RHS
I have seen the econodyne's here fitted with 2 aircleaners
I bought the kit to do mine even had the air tube to connect into the existing system
but i sold it before........
The inside plate is easy to miss. You have to look to see it.
They are hard to get out of a wrecked cab as you have to bend it to get it out
and realy hard to put back in. It is a strange shape thing that fits inside the door pillar
in a U shape that's where it gets it's srength as it is bolted inside
.
I could never find one in the parts book.......Mark

When putting an extra air cleaner make sure you put the stiffner plate on the inside
they tuck inside the door pillar or it will crack the panel . Seen it happen a few times.
The air cleaner and bracket are heavy.......... Mark

Hi, I have found an air starter tank from a CH Mack, its 58inches long and 15 inches in diameter, where exactly does this sit? i know it sits inside the chassis, but where?
Grant
Ducky that would most likley be just an air tank.
I think all the CH macks, at least all the ones i have seen were electric start
All the start tanks were up near the fuel tanks on the out side...........
the air tanks go either side behind the gearbox or where ever they will fit....Mark

The engine was an out of chassis re build
Piston to liner height checked under spec
New liners pistons fitted ring gap checked
over boost? "standard fuel" runs 21.75 boost. spec is 21.6
Now pistons 2 & 4 cracked in 4100.00 Ks
it took up to 139.00 Ks to crack No5
How come pistons 1 3 6 are still good.......
If pistons were hitting the head i would not be asking questions
it would have dropped a valve by now. Keep guessing........Mark

Mike i will let you know how it goes. Should be good
That particular brand uses MAHLE brand, Google them up
very good brand. Certanly better than the other brand........Mark

Thanks HK.
I have been pulling my hair out or what's left over this.
They jus talk round in circles down a Mack now as they are non current item now
I have learned how to decipher the markings and serial No's on the piston tops
and the different suppliers. All made over seas now.
I put it down to a bad batch / quality controll on the day.
The set i have now is fron a different builder and looks a better finish itm
I'll put them in and see what happens. Thanks Mark

Picked up the Re build kit. It seems that all the 2 valve pistons
are of the later design. I am sure that it was just a faulty batch.
They seem to be a little better finish. After a lot of reserch i now know the
company's that manufactured them. Never had a piston failuer in 30 years of
Macks. The PAI Kit was $2772.25 AUD so not too bad. Time will tell.........Mark

picture sez it all it think

All the pistons that failed were at the steel ring land

Thanks Bollweevil Gleemans have a kit in stock
Skip don't know why your's pollished the liners
I use rx super and never had an oil related problem
My engine has 98% hone marks still in the liner
Its just crap parts. Saying that it most probably
was a faulty batch
pistons 1 3 & 6 are still good
piston 5 was still good til this week
2 & 4 cracked at 41833
2 & 4 replaced at that K's still good

Have been thinking of PAI rebuild kit this time
have used PAI in the past with no worries at all
if Mack can only supply the after market stuff
they have lost me.
Is PAI still made in the US? may bee they have better quality controll.
going at this rate i will have to put zippers on the heads........Mark

bolweevill thanks
Now the engine was fully Rebuilt
pistons rings liners whe whole deal Jan 07
ring gaps spot on
done 41833 ks cracked 2 /4 nov 08. put it down to bad luck
Now No 5 cracked in the steel insert, done 139455 ks sept 09 piccy later.
the thing is pistons 1 3 6 are still good
standard fuel pyro never goes over 4/12 to max 5 degrees C.
owner driven by me. Sitll 99% cross hatch marks in the bores.
Me thinks crap parts. Remember the original pistons were in there for
11 years and were still serviceable.......Mark
-
Hi fjh I have the target for the piston cooling jets. They were in the
spec and careful when fitting the rods down the bore. The brown stain
inside the piston is uniform on all........ Mark

Gday everyone, Im not sure if Ive asked this question before but I'll give it a go, Does anyone know if liners or cylinder kits are available for an END865/6? They arent available here in Australia, so I dont care if they are genuine, aftermarket or old stock in someones shed, any information would be appreciated. Thanks all, regards, Skip.
Hi Skip
Try Thompsons transpory/ towing. Mt Victoria NSW
He had a load of V8 Mack stuff at one stage.....Mark

We have put another R in the shop its all ready but the front suspension is all crapped up. It has one eye in front and two pads in back that sit in rubber. Every where I have tried I can't find the main wrap seperate only the stack. All I need is the main wrap because we are putting in a heavier front end. Does anyone know where I might find the main without the whole stack. Also wen't to spring service and they wont roll the wrap because he says he can't put the metal pads back on. Any help is greatly appreciated or am about ready to take on a new idea.
Hi meado
Unless things have changed Mack will not sell idividual leaves any more after a fatal accident
i think in the US some time ago. At least here in AUST that was the case.
It is always better to have the spring re set to match the new leaf anyway.
it is not good to put a new leaf in a tired spring pack.
I just had two new springs made 3 months ago same type pad and pin
Here in OZ and my spring maker has always had the pads in stock.
shop around any good spring maker should be able to put the pads on. They are only riveted on anyway.
If Your spring maker can't do that. He is no good. It cost me $1375 for two springs pins and bushes...Mark
