    If you have work for a 99k gcvwr then buy a rig rated for a 99k gcvwr.

    Illinois roads

    JoeH posted a question in Mack Truck Q & A

    My parents are driving our MR688 from PA to Indianola Iowa. Everything they have heard is that Illinois roads are awful. Can anyone give us feedback? A couple route options: Rte 80 Rte 74 splitting to either 72 to Missouri or staying with 74 to Iowa. Anyone know what shape these roads are in? Remember truck is a cabover bobtailing on 20k steer axle. It rides like shit, and my dad is nearing 70!

    That you have it chugging along somewhat means the EECU must be working to some degree. Pull the valve covers, time to check mechanical bits. Check slop on rocker arms. Bent pushrods? This engine could have been over revved. Oil pan gets you a view on bottom of the engine: camshaft, debris in bottom of pan, etc. Valve covers tell you what's going on above.

    Measure how tall the frame is. I think 9" is a tractor trailer frame, 10" or 11" is required for dump truck work.

    The screwdriver trick I learned for motorcycles. Minor size/noise difference.

    Go to your dealer and order book # 8-211!

    3-4 is engine position sensor, located on the timing cover. Camshaft.

    Appears your VECU power is dropping out. This is likely the trigger for the 6-3 code, as the VECU dropping out will obviously disrupt data communication.

    So some Mack camelback trucks have a torque arm on the rear differential going to the right frame rail. It prevents the axles from walking. Check to see if you have one, check condition of the joints at either end. Replace if worn. Also, elephant pads aren't a terrible job, doable in a day, but they do take some serious torque to tighten down. Expect to replace all bolts, you will likely be torching some off. Few different styles of pads I believe. Some use a metal side insert some don't.

    Remove one side, separate, sandblast/paint, bolt back together, install, shift cribbing to other side, & repeat.

    This is the second truck I've done this to. Leave one side in to hold alignment of everything. Put jackstands/cribbing under everything on the other side, and pull the supported side out. Separate by driving a long 2x6 (cut the one end into a wedge) into one end. Lots of hard work involved, be careful you can kink the rails if you try separating them like a wish bone. If it's a dump truck you will have to pull the dump body off. First truck we did was an RD model, the cab had to get jacked up pretty high to let the frame clear. This one I linked is an MR, the cab tilts forward giving tons of room to work.

    Also that motor/trans has a lot to be desired for on hp/gears for 99k.

    If you want to haul heavier then hold out for 55/58k rears.
  18. JoeH
    You want 44k rears. Simply not worth investing in an underrated truck. The 38's will hold up for a while, it'd do the work ok, but potholes will beat the truck up. And you will be getting redflagged by DOT for being over the rated capacities of the truck.

    Where are you located? You might have an expert on here not too far away....

    Does it make a difference what gear you are in? Hi range? Low range? If you put your foot on the clutch pedal and apply gentle pressure to the throw out bearing (without disengaging clutch) does the noise change?

    A screwdriver is what I learned to use! Put the tip of the screwdriver on the engine or trans and cup the end of the handle to your ear and it's like a whole symphony suddenly comes to life.

    Call your dealer and get the part number from the heads for your truck. Use VIN from other years/models to check compatibility. Chances are your head # supersedes to another number, so make note of that number to see what else might have it. VIN #'s can be had easily from online auction/sales sites.

    Door lettering. Since we're buying our first brand new volumetric concrete mixer since 1967 from a company we have never used, I couldn't help myself. Had to add when we started into the business. These mixers were invented in the early '60s, so there can't be very many companies with as many years in "the business" as us. We're tiny, don't get me wrong, it's just my dad and I. Tons of businesses much bigger than us, but we love what we do and are quite happy being small and paying our bills.

    Yea I completely brainfarted. I've been 100% focused on getting our mr688 ready for Iowa. Stress is through the roof, we function quite happily in a 15-20 mile radius. 1,500 mile trip on a truck we have put about 25 miles on test driving since Monday! Fingers crossed no more hiccups! This truck leaves tomorrow morning!

    Coopersburgs Kenworth had a rare? used heavy single frame MR, 2 customers got into a bidding war over it. Heavy single is such a bonus.
