Ive got a 1000hr 2008 model 804b. it wont crank over with the master control switch. I have run thru all the diagnostics found in the TM. all relays test out good, starter is good, master/dead crank/ emerg.stop switches, and al three breakers test good. I can apply 24v to the starter solenoid...

Please delete.

i beleive all the issues the thread originator has had would have been mitogated by a painstakingly thorough inspection of tge truck, with the idea that every bolt may be hamd tight, and hoses may be routed incorrectly. Every single truck I have owned has needed this. You just never know what...

I have seen this before also! that was my thought too.

I owe you a public apology. You are correct on all counts, the unit was super crusted on there. I apologize and stand humbly corrected!

About 4awg.

My numbers are pretty inline from others ive spoken with. Mine are in a 1078. I was getting 5-6mpg prior. The old gears will kill these trucks at hwy speeds. Here is a photo of my gps showing 74 vs the tach. Ive hit 76mph but didnt get a photo with the tach.

Again, no. Look at my photos. These are lmtv pattern, with a built in Ctis regulator. Jeez. They are part of the wheel. The internal bits of thevalve can be unbolted but the housing is cast in. They are very slick.

Any idea what they were used on? Curious what the ctis looked like.

Wes, these CTIS do not unbolt. They are cast part of the wheel. Also, this pattern is standard budd lmtv pattern, i had it bolted on. The lugs are a tapered hole. I am familiar with the wheels you are talking about, They are not the same as this one.

Standard 10 lug (FMTV) pattern, aluminum hutchinson. Built in CTIS valve.

Not sure what you are getting at. Are you meaning to say that a tire rated for 9370lbs and 81mph, is not working within its perimeters when loaded at 5000lbs (or less), set at 55psi, and spinning at 75mph? Or are you just splitting hairs?

Goodyears are rated at 85mph....

Coachgeo have you ever driven a truck thats been re geared? Its a simple consideration of powerband. These engines make plenty of power.

I think you may be worried they dont have power for gears and tires. the fact is, These motors feel gutless because they are wrapped wayyyy out of their powerband with too high a gear for hwy. my truck feels at 65mph, how it did at 45mph before. The shift points have smoothed out considerably...

No. 225. I will be pumping it to 290hp soon however.

Sure are alot of 102” flatbeds running around.

The dimensions of the ring are irrelevant. In fact, by taking it down more than just opening the top, there stands a chance it wont load the pinions the same from warping when bolting (hypothetically). I simply took the top off a cap with a cutoff wheel, then faced it on a mill. It only needs...

Im more concerned with leg room than head. It did seem there was plenty of air coming out the bottom vent. if I could even get half that from the defrost well then..... Im going to poke around under there in the next few days.
