    the T300 is a smoother shifting tranny, with shorter gears.. as you know.  It would be cool if you had access to a 7 speed for practice to see if you like it..  When I drive them, I count in my head, 1-1000,, 2-1000, shift. I double clutch so so when I come out of gear I say 1-1000, (nuetral) 2-1000 into next gear... it's silly but it works for me,,, then after a few minutes i'm back to having a decent rhythm I still scrape a gear here and there.  The blue button on the shifter for the 7spd. is for low and low-low. you start in low-low, then go to low. if you need to use low range. then when you change the range you have to flip the blue button up as you pass through nuetral, because it is not synchronized...  like the 9 spd. you have...  

    I have gotten where I only use the clutch in that 9 speed to take off. It took a while but I got the hang of it. So it seems that 7 speed going to be a lot pickier than 9 speed. 

  2. I don’t mind slow either jojo. I get passed all the time in my Toyota Tacoma. I’m just not in any hurry. Where I’m from we have quite a few curves so going over 50 loaded is going be average.

    is this a big difference from that 9 speed T3901 I’m using now. Since I have never driven a 6 speed where is the difference. If that’s a fair question 

  3. This is just a post for information. Saw an ad for a low miles 2000 rd690s with a seven speed. What little information I can find, not many people like the seven speed for a dump truck. Where these trucks mostly day cab trucks that were converted to dump trucks. Shows double frame,  em7 300 horsepower.  looks like a nice set up all except the seven speed. Just gaining knowledge so appreciate the information

  4. Some of these 90’s model rd688 are showing 200,000 to 300,000 miles on odometer. You would think they have rolled over. At what point is the mileage to great of a risk. Say a 1.2 million mile Mack rd688 that has had motor rebuilt.  At what point does it become cost prohibitive with the transmission and rearends

    You can actually see the bushing out of center in that one picture and the leafs are worn into one another. Time for some new springs and you'll need someone to either find you the heaviest to fit the chassis or add to it like someone already did.  They're only rubber bushings and not very good at taking the pounding  greaseable pins and bushings will .

    Where do you see the springs worn into one another. I can’t see what you see.

    Sir ,what you are describing in my opinion are the bushings as you have suggested.our 2 mack chs have this problem.since they were over the road and since converted to dump truck the rubber bushings don't hold up.. usually we can get a year out of them.they are not greasable ,either in the front or the back at the spring hanger.They noise is most easily heard when turning loaded.see if upgraded polyurethane bushings are available in your area.. polyurethane usually last longer.. picture above from onyx is from an axle that has threaded pins and are greasable...and a later year model to yours ..indicated by the 3 holes on the pin,which I believe is a Volvo design.

    Red.

    What do you guys replace your bushings with? Have you guys upgraded your springs? If so what with or do you still run three leaf that came on truck.

  7. Thank you guys for your response. I appreciate the time and information you guys have given me. Again I really appreciate your time and patience. 
     

    is this something a guy with some mechanical skills perform? I’m talking replacing the springs and bushings and pins. I have replaced a few leaf spring packs on Toyota tacomas but Never have owned a big truck or been around them much. Bought some land and needed to build some roads and move a lot of gravel. So bought this truck and a excavator and just started doing it. The biggest tools I have are 1/2” drive and a Milwaukee 1/2 impact.

    Good solid piece of wood and how ever long you need to to get between the tire and frame. Once you turn the wheel into it the distance will close. Your just using the power steering to help you move the axle beam which would show a loose spring pack or bushings If worn. It won’t hurt anything as long as the wood isn’t on like a abs modulator valve or something haha. 

    Onyx610 I just don’t see where to wedge a block of wood at to turn steer tire into it. Like I said never seen it done so having to visualize it. The brake can in the way on top and nothing to wedge on the bottom

  9. Sorry guys but my son is down wiring up my shop. It’s gotten real cold here. I took this photo of the drivers rear spring bushings.

     

    something is definitely loose because when I turn and truck shifts weight to say passenger side I hear and feel a loud clunk. I feel it in my feet. Same when weight gets shifted to drivers side.

    I'm guessing you have #14,500 front springs, 3 leaves...  the band clamp on the end of the spring pack is basically an indicater for shifting spring's.  Are they shifting? if so ...  jack the truck up and support the frame. crawl under there with a sledge hammer and try to straighten the spring leaves, if you do... they are loose..  probabley 1 1/8" socket put the toughest 3/4 gun on it or 500lbft  or whatever you can pull... test drive the truck "at work" and re-check e'm....  jojo

    Here are my springs. Only band on the set.

    You can put a piece of wood on the inside of the top of the tire between it and the frame. Have someone get in the truck and turn the wheel into the wood and you watch the springs for movement. If the spring pack jumps or clunks it’s the bushings 

    We talking a 2x4 piece of wood say 3’ long. Sorry to be anal but I have never seen this done so I’m trying to understand.

    Jojo when you say straighten the springs I’m guessing your thinking one end is bent toward opposite tire. (Just an example) and if that’s the case knock it back in line and then tighten the hell out of nut. 
     

    what do you mean band clamp is an indicator for shifting springs? 
     

    sorry guys this is my first truck and I’m about as green as a gourd.

  13. Jojo I read a thread where you were going help someone hook up shop air to their dryer but they didn’t think they had one.  With that said what do I need to do this? I have chronic tinnitus so looking for air leaks without the truck running is a big plus for me. 

  14. Ok I got a chance to look at another Mack CH and I saw the two brackets you guys are referring to. I definitely don’t have them. I will work on finding them to install. 
    When I bought this truck I knew it was a little rough. I’m basically fixing up some property that’s been in my family and building roads for the property. My ABS light is on and I’m thinking most of the wires to the wheels have been cut. Would you guys hook the abs back up. I personally don’t use it much on the road but to get fuel. More than likely I will be putting farm tags on it at renewal. With that said I also want to be safe and not cut corners especially if it keeps me out of a wreck.

  15. The bottom photo shows it running along the transmission and top rail by exhaust. I don’t see anywhere to attach it to the top of transmission. Do you guys think this will be ok with the exhaust this close. My only other option is to drop it down when it leaves the compressor and run inside frame rail to dryer but I’m thinking it will create a low spot this way.

    IDK how long they're required to be, but they're like that on account of the heat. Even the P clamps are lined in Teflon ( usually white on a Mack )  lots of them switch to something else with a fitting that is bolted to the transmission.  

    Mark what do you mean when you say lots of them switch to something else?

  17. Jojo got a question for you. Had an air leak on the 2003 ch613 and it was in the ss braided hose off the compressor. The guy before me had a 4’ ss braided 1/2”I’d hose connected to a 6’ hydraulic hose that was connected to dryer.  I know the hydraulic hose was wrong. If I understand you correctly that -12 fits a 5/8 nylon braided hose correct. 
     

    I’m  wondering if I go to a Napa parts store they will know the correct hoses or do I need to go to a Mack parts store? Thanks Ricky
     

     

  18. I have a 2003 Mack ch613 that was converted to a dump truck. I’m replacing the line from compressor to dryer and it’s 80” long. I understand I need ss braided hose when I leave compressor but instead running whole length in ss braided is there something cheaper I can run after I leave compressor. I will run braided if needed but seems like overkill to go total run with braided. Thanks Ricky
