Looking online at a couple petes that Sullivan has at an auction at Chariton Iowa going on right now. The list a model with a Last I looked it was over 18, online and hasn't even sold at the sale yet. Would that be an E model Cat?

Also listed a with a Was over 4 grand last I looked. Would that one be a B model or C model Cat?

year should be a E. unless swapped out.

'87 should be a B model


Central NDYou seem surprised at that price? If it's a decent it's got $10, to go yet

I agree, but be forewarned, that "could be" a PEEC model {= CAT's first attempt at an electronic controlled engine with "not the best" reputation.}

It could be a typical mechanical governored engine, also. (pretty good reputation)

 

Need to see the fuel injection pump and governor and/or engine serial number to identify, between the two "B" model engines.

I thought the PEEC motors were on the C models which would have been out for a only a year or two before the E. Like ish.

Here are serial number prefixes and dates, for PEEC. (notice how only the bottom line is a "C" model = "4CK" prefix)

Thank you! I didn't realize they made the early electronic throttle control for so many years.


Cleveland, MS. Own small farm near Booneville, MS

FWIW, I drove a International with a B for a couple of years. The only electronic problem I had was a speed sensor went out once. Other than that it was a great engine. Set at hp it would out pull the 60 series Detroits in the fleet that were set at / hp.  Both were running the same rear ends and transmissions. The Cat had a throttle linkage from the pedal through the firewall. The throttle sensor was mounted on the firewall. Later models went to the "fly by wire" system where the sensor was mounted directly under the pedal. No linkage, just wires.

Would the 94 have been the start of E models?

Our 93 has that serial number that starts with 4CK. Freightliner told me its a C model according to the VIN. But it has a B model injection pump on it I'm pretty sure. Has a mechanical linkage going from cab to governor. It also has switches in the dash for cruise but it don't work. I'm assuming because there is no longer electric throttle controls.

Sounds like your truck, was originally a PEEC "4CK" engine, that someone swapped over to a complete mechanical fuel injection pump, governor and timing advance unit.

(Note: Visually, you wouldn't be able to tell the difference between a B mechanical fuel injection pump VERSES a C mechanical fuel injection pump)

 

E models started in late , but the C models were still being produced also(for semi-trucks) = Customers had their choice of what engine model they wanted until at least or so, then the C model was dropped, from the Over-the-Road "new engine" line-up.

Id say you're right on the pump swapping thing. Guy we bought it from said he just had it replaced and there is paperwork in the glove box for it. Don't know if the C pump was removed then or previously. Wasn't done at a Cat dealer. Probably couldn't get Cat to do that anyway. They would probably have to go back with a C model pump.

  3. in my experience, tops Why is that?
    &#;s are "intercooled" where the is "air to air"..

    With a "charge air cooler" the volume of air you have to fill before pressure is seen at the intake manifold is far greater..

    The benefit is pulling long hills with lower exhaust temp..

    So.. You may beat a through the gears..
    But when you get down to buisness on the mountain..
    It will be a sad day for the &#;s..
    :biggrin_
  4. Well no thats not quite rightMy Cat was air to air too. I&#;ll never forget the time I was in NM going west and a couple guys were patting there self on there backs(via the CB) as to how well they were going up 9mile hill on I40, I know one of them said they had a Series 60 Detroit and the other was a Cat, both had reefers. I never said a word as my little tanker yanker went around them both at the same time.
  5. Mechanical wont adjust timing and fuel for elevation changes, etc. E model hands down, way better engine, bullet proof and will put down +hp without breaking a sweat. The B model is a liability past whp, been proven. Better millage, dont have to worry about bearings every k. Not trying to say the B model is bad because it is bullet proof but at hp, not ( over and out)
  6. No passing Detroits aint a big deal, unless the one your passing thinks there doing a hellva good jobreread my post.
    I do believe your vast carnal knowleage of Cats has failed you, Late 80&#;s vary early 90&#;s all Cat&#;s were air to air including the In I had a 3ZJ C Cat that was in fact air to air and would out pull most any other stock
    No where in my post did I ever say I had a "B" model Catpay attention Junior

    Unless you fancy having your dress pulled up over your head.. and getting bent over in public.. then you really need to learn what you are talking about before you post..

    I am pretty sure you must get off on it though.. because this is twice that you have disputed my post with nothing but pure BS for backup..

    So either produce a engine serial # for a 3ZJ ATAAC # hp.. or be humiliated everytime someone reads this and has access to SIS..{where Caterpillar keeps records of all engines}.. and you also will have proof that you are retarded.. and then you can give up truck driving and get your disability check started..

    Also.. if you were "sucking the fuel out of the tanks of the &#;s as you went by" you were in the right lane with a large straw in your mouth.. :biggrin_


    New Dynamic Fuel Ratio Control (FRC) Settings Provide Improved Engine Response

    SMCS -


    C (3ZJ) Truck Engines
    There have been some performance complaints on and model year and hp ratings. These complaints, in most cases, were tied to engine response rather than actual engine horsepower. Caterpillar now has new EPA certified FRC settings for the hp standard torque rating for There are also new EPA certified FRC settings for the hp standard torque rating and the hp standard and high torque ratings. These new settings are included in the chart that follows. These setting changes will improve the rpm engine speed turbocharger response by fifteen percent. Under some operating conditions, the setting changes will improve the rpm engine speed turbocharger response by thirty to forty percent. An engine with perceived low power or poor response may have the FRC settings changed to the new values.

    When a timing advance and fuel pump are set right to begin with.. it is already where it needs to be.. the only adjustment would be backwards.. so if you can use your right foot and read a gauge.. there is way more to be had than with most ecm programs.. This is the only reason I don&#;t like the E&#;s..

    I&#;ll agree with you that over time the was beefed up.. There have been some good changes.. but not always for performance..
    If whp from a working truck is not enough.. then you will be spending money on either engine.. You should know better than most that the price of playing goes up with the year models and emissions laws.. and you can beef up the B model rod and main bearings.. you can even go electronic if you wish.. but I have yet to see the need for either..

    Also.. the electrical wiring and sensor issues with ecm engines will shoot holes all in your bullet proof theory way more often than spun bearings ever even thought about it..
