on a ch613 do you change the valve from in the cab ? i can see it on the firewall. mech cross threaded it changing hose.

we have a 93 cl713 in the shop for rear end repair.our driveline guru says it has 55k rear ends.seems kind of heavy duty to me.also top speed is 92 mph.could one of you decoders ( barry) tell me what rears & gear ratio we have here? serial # 1m2ad38y0pw001382. thanx in advance!

leaks with brakes on or off .have to try trolly brake on.cant trace it. it goes everywhere, into this block or valve or switch into that one,on and on and on..................

ive got a short piece of synflex that comes through the firewall to nowhere. it leaks air all the time. on the cab side it runs to a block of some kind that has 2 more lines coming off it to who knows where. dealer said its a parking valve leaking but all 3 have bee replaced in the last year. had a r model that did the same thing but not this bad .driving me crazy. thanx in advance..

i had the same thing with my 97 427.after going through everything fuel and electrical at the dealer,it turned out to be the sensor that times the engine off the back of the flywheel.i forget what its called but it took along time to figure it out.

i have the same problem. 97 427,dont have the pot and breather on rh front.i do have a blowby tube from the valve cover,that smokes just fine.

my 97 ch 613 weighed 17020 coming off the assembly line. with a 40ft stretch trailer she weighs a lite and lively 35860.........

Thanks for the help, I went with the Baldwin filter. it cost me 12 bucks. I cant use the mack boxed filters because I am using the B-model fuel filter.

baldwin and hastings filters have merged or something like that. weve used hastings for years.never a problem............

someone else drove my truck. now when i shift from the low side (4th) to high side(5th) it grinds like crazy. synchros gone bad, air problem ?its a 18speed fuller. i hate when someone drives my truck !!!!!!!!!!!!!!

72 was popular 10 years ago in quebec and still a bit now in Ontario, most use is 60 right now.

my ch 613 has 60in.spread ........

I have a 2002 Mack RD688S with an E7 engine in it. When you turn the key on, it powers up and everything seems fine, but when you go to start it, it wont start. We changed the ECU with one that works, and we checked the VECU also

transfer pump if it has one. been there done that...............
