our mack starts loosing boost right around 1600-1700 rpms. it flattens right out. has new turbo and air to air radiator on it. think injector pump is getting bad but hopefully you guys can help me out. It gallops if it sits and idles. been told if i remove cover off side of pump and theres brass pieces in bottom then its wore. dont know how true but hopefully i can get some help on this.

yes that is what i was told. and if you put seals in it and your shaft is pitted then it will tear your seals up.

thats what i was told by a few mack mechanics but idk

1989 rd690s steering box leaks and issues after new seals. looking to replace. new or rebuilt? i was told not to go with rebuilt. anyone have one? its a sheppard 492S5-6. thanks

idk dads has had a new duramax every year since 2004 and never had a problem. had a 2000 F550 with a 7.3 and it was a great engine as long as it didnt have electrical issues and didnt burn up

it used to be bomax where there building it.

haha there building the nice n easy on coffen street on road to beam mack. no wonder why its sitting there then. must be they do them all. haha

too late now.. haha oh well.

monroe mechanical from weedsport ny id love to have it.

they all said complete would take 2 months to make so we called our mack dealer and it was here in 2 days. with a mack symbol on it. others were aftermarket and wanted 150 more

just bought rad for our rd complete for 2450.00 because core was 1800.00 at all the places.

pretty cool idea.. i wanna find a single axle someday and redo it

okay. and yes it was. it was bought in new jersey and brought here. guy used it for a year and its been sitting since 2006. but it started right up with a jump and we drove it 30 miles.

lol thats what i went there for today.. haha price on brakes and a blower shield and stupid crap.

yah lol.. that was our parts truck we bought but nothing is same really. could use it but to good for parts i think.

more pics $9000.00 or best offer dont be afraid to offer a better price
