I have replaced the transmission the other day and was thinking maybe the RPM sensor on the flywheel housing maybe?

I still I have power to the cab, the a/c and lights are operational but the RPM gauge goes straight to zero.

If it is a total electric cut out. I would look at wiring issues, or even hot relays. They are in the panel on the right in the cab fuse panel.. I should have mentioned the ground connections...

Hello, my 2002 CH613 is cutting out and dies while i am driving. I can cycle the key and it will start back up but not an ideal situation in traffic.

They called Mack .....Gabrelli and said to send somebody down we want to buy tri-axle's.....wouldn't come ......But CWPM still buy's Mack's have no option Garbage truck's

Bob, how did they look in Allied Van lines colors those days? Bright orange all over? I like the look of them H's.

H-65 - a non-sleeper cab? Or am I wrong?

Also, I was wondering what year tow drivers started removing the driveshaft

Forgot to mention, they were all painted Allied van lines, colors, and all in really good shape like they had been restored

I don’t even recall ever seeing one on the road when I was a kid I’m sure I did, but when I moved to California and used to go to the Bay Area quite a bit I believe it was Allied. Van lines had a bunch of them running around the bay area all cleaned up middle 80s. I don’t know what was up with that and I don’t know how many they actually had, but I used to see at least one of them all the time around Oakland. Still working… Aaaaahhhhh good old days.

hope it wasn't because of a calendar LOL. speaking of which I did a visit recently to one of my yrs back customers. a guy who threw nothing away; some items were Mack calendars back to the '70's and up . I quickly looked for the controversial HI/Ho == O&G picture; not found. 1- I don't recall the year= had to be mid late '70's -early 80's. 2- some calendars were brittle , didn't want to ruin. will keep searching the pile one day. he's not getting any younger ; kids will call in a dumpster 😨

wasn't Manafort tied in with Arute some how ??? there were a few fleets back then having the black/white striped "safty" front bumper paint scheme.

one thing I can tell you about the H;; if your in one on a cold winter day ;it don't start so you are being towed by a diamond T wrecker having a pull plate of 2 in steel in the upright position::: MAKE SURE THE DUPLEX TWIN STICK IS IN BOTH MAIN AND AUX.!! with no air built up and a hand brake which is frozen not much to do when the wrecker stops for traffic and the H model doesn't stop till the crash of the wrecker pull plate modifies the bubble nose of the H. this all takes place while the service manager and 3 prospective buyers watch. main was in gear aux wasn't. new rules took place after that.. pull plate down to bumper height/ air will be built up in towed unit . LOL

H-65 were made '55- -'58 total number produced =====63.also produced WERE::: H- 60 /62/ 64/ 65/68/69/613 -only 3/628 -'55 only 2/633/653/673/693/81/813/6-8WC in'56 only 10 .... interesting... H-61 '52-57==484 made ///H63 '54-58 ==4091 made (hot seller)///H-67 '57-'62==5954 made (real go getter).

My pictures posted out of order. look at the tes numbers to follow the steps correctly..

Here is what is in the V-MAC III Book

lol beats me I don’t know anything about them. I’m sure somebody else will chime in

Volvo must be pissing their pants-Mack orders and market share were higher than Volvos recently!

H-61, H-63, H-67, What happened to the H-65?

H-61, H-63, H-67, What happened to the H-65?

Manafort another Mack user gone to Paccar

What HE SAID! I am feeling every trans and drive line and main bolt I have ever torqued every day! Every joint hurts ! I think it lowers the motivation some what !You Got to just over look iT If you want to get stuff done ! Ignore it and power thru! 4hrs at a real slow pace is about all I can tolerate these days! Count ourselves lucky were still able to do this stuff! Could be alot worse!

So investigate this! On startup turn the key on observe the pistion on the VGT ! Is the vgt doing its self check? Is it going full stroke ? If it does not stroke out both directions it may be that the vanes are sticking and not allowing the turbo to regulate properly!
