    D342 Head to Block Clearance - Feeler Gauges

    I cannot find the clearance tolerance for the flatness of the block to check with a straight edge and feeler gauges. Does anyone know what we need to have before reinstalling the heads so we know if we're going to need to deck the block? I've looked and looked for the engine serial number but...

    B30E EGR Cooler Leaking - Replacement or Aftermarket Availability?

    One of our newer B30E's (BAT7333 SN:8785) has developed an EGR cooler leak. I am being told this is a nonserviceable part. I called around to a few of the google hits on searching for "EGR cooler repair" and everyone I've spoken to have said "no can do". The engine is an OM936LA. I don't know...

    Bucket Teeth Question

    We are die hard Esco bucket fans. Mainly for the ultra lock teeth system. However there is a premium charge to this affinity. We’ve had/have Hensley buckets but I am not a fan of their pin locking system. We took one Hensley bucket and swapped over the shanks to Esco. Are there any other...

    Phase Out of Non-Emission Engines

    Has anyone here lived through Californias regulatory spin up when they began to regulate off road equipment the way they do today? I’m curious to know how it was introduced and then implemented to the fleet owners. I do not believe where I am located is in any serious risk of seeing the same...

    We have a PC360-11 (SN:A35212) that may need to have a some work done to the main valve body. Other than the dealer, who could I possibly send the valve body out to for rework/rebuilding?

    ADT Scrapers Question

    Has anyone had much experience with the ADT mounted pull pans from Ktec and MTS? I’m interested to know how they hold up in the long run with drop boxes, transmissions and axles.

    Throw Back Truck Setup

    Just an idea but what would you all think if you saw an old school setup of a bottom dump and tractor running site work jobs like what I’ve seen in old videos from when they built the St Lawrence Seaway and the Garrison dam in ND? Kiewit has 9 Atlas dump trailers up for sale for under $12k and...

    HM300-3 Bed Drop Issue

    One of our 2 HM300-3 (SN:3040) trucks has started dropping the bed extremely fast when you press the lever forward into the lower position. I was watching them make round when I first saw it happen so I climbed in to see what was happening. When the bed is loaded if you raise the bed up and then...

    We have a Link Belt 3400Q long reach (SN:E718-9519) that sporadically will not resume hydraulic function when disengaging the safety lever in the cab. There doesn't seem to be any pattern to it. It will malfunction when the machine is hot or cold and from first start to 8 hours into shift. I...

    One of our HM300-3 has developed some blowby. Started with getting a crank case pressure error high that escalated from a low level alarm (L01) to a high level (L03) alarm over the course of about two-three days. We followed the manual on what items to service and in what order but maybe we...

    621B 8HC SN Service Manual

    Would anyone happen to know what SN prefix is the closest to an ex-military 8HC prefix serial number 621B to a standard 621B series SN prefix like 45P? I need to get a service manual and am unclear on which SN prefix would cover our machine. Our machine: 621B Wheel Tractor Machine Serial...

    AirBurners Trench Burner Thoughts

    We just wrapped up burning the clearing debris from about 20 acres and I rented an AirBurner brand trench burner. Over all, I wasn’t too impressed with the machine. The air volume moved was much less than I expected. We have an old Finn Fire Ball 2 that burned much more volume than this newer...

We have a leaking injector seal and our mechanic does not have the tool to remove the lock nut holding it into the head.

    How To Move A Dead D8H

    We lost something in the transmission of our D8H and she’s immobilized where she sits. Operator was in a straight line push and hear a loud pop under his seat and the machine came to a stop.
