    What rear axle ratio do you have in the truck? What Engine do you have in the truck? What size tires do you have?

    An E7 427 as far as I can tell is the best that Mack had to offer. When these trucks were new their was some tuning the Mack garage could do to pull better power out of them. Looking back at your post this truck being a 91, it is a mechanical engine, you are better with that engine than any other. As for parts: Iowa has a lot of options for truck parts, But compare prices, some truck dismantlers are higher priced than others.

    Lets have a picture of the truck, maybe that will help with what we are talking about. Some of the best trucks made are from about 85 to 2005, your truck is right in the middle, and in the 90's Mack engines ran well for short money. An E9 is cool, and if you have a super liner with an 500 that is cool, but there is alot of money to keep one going and you have to be careful how you run them. A 400 E7 you can run all day every day cheap.

    Seems to be random, one morning it will fire up right off, another it will crank for a long time. And warm or cold makes no difference. I did pump the primer hard one morning when it was doing it and no difference which had me scratching my head. I will look into the sensor issues, are the cam and crank sensors easy to locate, assume the crank sensor is above the harmonic balancer?

    I have an AI 400, not sure if that is a "E-Tech", but the 400 falls on its face below 1500 Rpm, which is the complete opposite of what the old tride and true Macks of the 80's and early 90's did. The transmission can make a big difference if you have some gears to work with, and multiple posts on here about solving some of these power issues.

    Sometimes turn the engine over and it starts right up, sometimes crank it over multiple times before it will take off. Changed the fitting on the side of the block thinking it was not holding fuel pressure, acts like a check valve that is not holding its prime.

    Take the line off the range cylinder and put some air tool oil to it. This may help an old dried out O-ring.

    This is similar to the sequence Cummins uses for injectors.

    Pretty sure the buzzer died, the dash light says low air pressure but the buzzer doesn't come on, switching the power divider lock on or the turn signals on doesnt make it buzz either,( they use the same buzzer best I can tell) The buzzer sounds like is integrated into the dash cluster and is almost a grand to replace. So working on hooking up a regular buzzer from napa, the advantage is no buzzer when turn signal or power divider in. But which switch is for the low air buzzer to tap into?

    It is a Mack transmission, It was advertised as an 8LL, However it is not, It is an 8 speed with a low, no extra blue button Low, just down to the left low. The tachometer, reads pretty high, and has various colors on it that it states are good for engine brake. If I remember correctly the 310 is a version of the 18 speed Mack transmission. Last 18 speed mack I had apart to repair the Hi/lo, the repair parts were almost the cost of a used Fuller 18 speed.

    My 2 cents would be to look at it as 2 separate shifts, one to pull out of gear and one to put it into gear. Personally I tap the clutch to pull out of say 5th gear when down shifting and float the transmission into 4th gear.

    Just bought a CV713 Granite dump truck. I was looking for a fancy Peterbilt or Western Star with a C15 Cat or N14 Cummins, but those are big money. I have a few customers in my mechanic business that have 03 Macks and they seem to get good service from them and day in day out they just haul dirt without the flash, so I followed their lead. Coming out of a truck with a Big Cam 400 and a 15 speed, this Mack E7 400, Mack 9 speed is a totally different truck to drive. Any driving tips for RPMs and such appreciated, also any issues I should be looking out for. 18 Front, 44 mack rears, Chalmers suspension, Mack 9 speed, single frame.

    First I would like to say engineers are stupid, whoever designed this should just quite, and go sell kites at the beach. Second is this normal? The plate is offset from some of the pins, says nothing in the service manual and I have twisted this plate until i was blue in the face, figure it must twist when shifted. Bought the "Update Kit" with new synchroniser plate and gears.

    The owner of the truck insists on Mack parts, and I think the down time for him is the bigger cost right now, tore it apart saturday, put parts order in this morning, could have parts Tuesday, fingers crossed. My fear is forgetting 1 oring that will hold up the whole job. Judging by your comment puchasing the injector cup tools for C15 last month was a good investment.

    I always thought Mack Transmissions were wicked rugged, 6 speed and 12 speed especially, figured 18 speed would be similar, didn't think you could break one.

    These allen bolts were loose, took off with my fingers, looks like they hit the plate.
  17. DieselDog5.9
    Snap ring broken in outer groove.

    Broken Shit

    Low Range Clutch Smoked.

    Yes, took me a minute to figure that one out, moved the gears a wisker to line up on a gear flat, they could have designed the tool with the bolts 3/4 inch lower, got your message when I got home was glad to get verification. This picture shows the tool in place and the rear box off.

    On ATHS website, may be an old listing.

    H Hopefully these will do the job

    Sorry not sure how I did this but truck is a CV700, not a CL. Yes I agree on the bell housing, just changed one on a W900 last week, actually had a cast iron Halo bell housing that broke, not sure but feel like W900 may have been wrecked at one time.

    No ISX here, In Northern New England we dont mess with macks and do funky new age stuff, Macks are Macks, E7, Mack Trans(12spd prefered), camelback, with spoke wheels, once in a while some hippy will have an 8LL Eaton Fuller. I would guess within 30 miles I have the largest concentration of E9's in the country. One retired logger I know has a marine E9 they put Jakes on. The publication number is 10-701, hard to find things on that site but I looked at the kent moore book and got the number.
  25. DieselDog5.9
    We did think about switching to an Eaton Fuller 18 Speed, but need to get back to work without the BS of extending the driveshaft and other associated bs that would need to be modified. She is an ornery shifting bitch.
