SLEDOG

No work done on carriers and wheels spin freely…..

Not too sure Mrs Mack…

finally got a chance to talk to my tire guy and he said they do that all the time on a Mack with no problems….

 I still think I have a problem with power divider somehow and I know it’s not permanently locked in….

Sledog

Same supplier on recaps but I am going to check with them tomorrow to see if they changed compounds or something….

I didn’t try rotating yoke on driveshaft….

I don’t see the locker is shifting in and out properly when air is applied ….

Thanks tjc I’ll check that also

Ok Joey I’ll look into that….

The air acuater for the pier divider lockout…is that supposed to slide off when bolts are removed? I can only move that back an 1/8 inch when trying to pull that off too check it out 

Torque arm bushings look ok…box rubbers look like they may be coming apart….new trunnion bearings a couple years ago so I HOPE they are ok…

It does dog track a little….

Camel back 

I installed a set of new recaps across the front tandem on my Granite triaxle dump truck. 
in 8000 miles I’ve lost about 80% of tread.

Is it possible the power divider is not functioning properly to cause this problem and how do I check that?

Got it running today….

Bad connections at a few key fuses at fuse block in cab.

Starts well but no throttle control . will be checking that next..

Thanks…. I have now realized that there IS a self-diagnostic test I can perform on this.

I will be checking this afternoon to see if any faults are stored.  I have noted that a bad crank sensor won’t throw a fault…

I watched that BobWhite…I don’t have the scan tool…I see where there’s a big round plug on the dash for it.

thanks 

It’s the T444 motor which evolved into the 7.3Powerstroke as near as I can tell…

I realize this is not a Mack but you guys are good so here I go….

Crank/no-start . Obviously some electrical issues at fuse panel on driver side.

power box with fuses under hood test ok

I believe I have fuel pump issue as well but want to check all electrical first.                    I  have no fuse or electrical diagrams.

can anyone help?

thanks

Ok thanks Onyx 

It looks exactly like the pic from RED’s post.

back of pump… upper left side of engine…

Which way do I orientate the check valves when I install them into the filter head?

Ok thanks Onyx…I’ll try those numbers!

Don’t know Joey…how can I tell?

I just came in late on this convo but I used to own a 97 RD 10-wheeler spec’d-out like you have…double frame and everything on a dump truck with aluminum box….great truck and would out pull my 460aset any day of the week!

Good choice putting the 18 speed in there…

I have realized the filter manufacturers list a coolant filter for my aset/ai motor.

My Mack main/lube book states that this is an option on these motors.

 I guess I should find one and bolt it on there right?

Can someone please post a pic and part number on here. Thanks.

Is there a way to check for proper operation of jake brake on a AI-460 without removing valve covers?

 Thanks - Sledog 

Ya Joey it was right behind the control board on the right hand side. It doesn’t look like it popped off by itself…. Probably was swapped with her sister truck and never got hooked back up…. Pretty sure it’s been like that since I’ve owned the truck……

Sledog 

I found it…the rod for the flapper wasn’t attached to the lever for the control knob.

reattached it and all is good.

thanks for response guys.
