sorry yes front drive axel and single frame and air ride

My R frame has gotten very thin under the fifth wheel,so want to replace both sides its a sleeper truck.Was looking at Mack body builders it shows the further ahead you go of front drive the downward weight increases,so i was thinking of replacing from the back to just ahead of front axel then put 4 foot inner sleave in,the frame is good otherwise just under the fifth wheel.Any thoughts/advice on this.

83 year old guy was wanting to sell and retire but changed his mind for now he ordered it new thats all i know just talked to the son inlaw guess has afew other mint r models.i pull around 90000 pds.

whats your thoughts 03 mack 460 with 10 speed is that a good combo for heiver loads.

mines a 87 had mine replaced as didnt pass saftey the shop didnt have any problems getting one

mine has this works very well in -30 C has toggle switch on the dash still have to have butter fly window open about an inch to keep windows from fogging up.

My E6 4V did it to but sounded like from the side intermittent at idle was doing it for couple years,Don't recall hearing it after new injection pump.

Looking at 87 mack superliner RW 75 are they quit a bit heavier than the 600 superliners this one has 3406 cat 9 speed maxi torque.

Its doesn't seem to be pumping oil builds air a bit quicker.Mack mechanic told me a guy replaced compressor on cat engine he let it run 1 hour to break in he said compressor was so hot.

yes forgot to mention mine has a splitter on the side.thanks

yes mine just has dir and lo

replaced with new one was told to open tank run at 1100 rpm for half hr to break in the rings thanks for the replies.

Thinking about replacing my old 13 speed fuller shifter knob has two speed splitter not 3 to new style is it just a swap or is there more to it than that.

keep air filter serviced.Good advice tho wouldn't have thought of that.

i've put two rebuilded air compressors on my mack E6 350 both pump oil was wondering if getting one from Mack be better.dryer leaks oil have to change cartridges quiet often.
