    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. There is a local outfit using MTS MT42 pull pans on 745 trucks and they look to be a great way to move big yardage...

    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...

    Revisiting Cat Pans

    A good friend of mine is working on a new power plant north of Tampa and they’ve moved in 2 MTS scraper tractors with Deere 20cy pans. So far he’s telling me they’re holding up but they’re only pulling singles and push loading with a D6. The last job I was on was also in Tampa back in 2012...

    Link Belt 3400Q - Long Reach Hydraulic System Lockout Not Unlocking

    Thank you for sharing. I was able to get my hands on a shop manual from Sawdustmaker and it's for a JCB of the same build. They look pretty dang close to being the same diagram. we're going to bring the machine in to the shop for a look over.

    Link Belt 3400Q - Long Reach Hydraulic System Lockout Not Unlocking

    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...

    9BL 963B boom hydraulics weak after a few hours of work.

    Locally Yancey is our dealer and their parts guys in the pump department were telling me that they had no availability on the pilot pump. The pilot pump shows as part number 107-4321 as a rear section. The pump group with both the charge pump and pilot pump come up as pert number 6E-6046. Says...

    9BL 963B boom hydraulics weak after a few hours of work.

    Wanted to offer a suggestion for another area to check on your machine with the hydraulic issues. We found that on our 963B that the pilot system was causing it to act up because the pump was cavitating. We had the pilot pump grenade and got to looking into what happened and found that the...

    621B Lost All Hydraulic Function

    I’ll look this up in the manual and show to our mechanic. Could be the culprit and sounds like an easy check

    621B Lost All Hydraulic Function

    I’ll have to find out. When we picked up the pump the shop owner has gone out of town for a month and didn’t come back into town until recently. We checked pressure on the pump and it was only making 300psi. Should he at 1000psi. He said to pull it off and bring back for him to look into it...
