going off topic a tad. short version;; yrs ago i go to truck dealer i once worked for. new kid in parts room. i'm looking for an  oil pump pick up tube gasket for a 6-71  i put together, i can make gaskets ; NOT that one, too important. kid says i don't have that gasket. i know that parts room  i been in it. ' i says = you don't have an engine kit in there( i know he did) . take out the gasket and replace it later" he says i can't do that its not in the computer system. i took the pick up tube and said you want this pipe around your neck. i was p--sed .  i got the gasket and paid for a number he had on the computer system. older manager had been there it would have been " take the gasket , i'll mark the kit  and call you when gasket comes in and you can pay.  so different times

this is one of many reasons i'm from the "grumpy generation" , i (we) know what our parents and grandparents had ;; not much. we see the next generations have so much (except common sense) just can't understand. If =when the electric grid is shut down this world is in a heap of trouble.

Yea we had a HO-JO nearby when I was growing up , I wish it was still around!             I also have a parts LJ that was Green, it has had the door frames painted White?? Never noticed this on old trucks until I started thinking about trying to repaint this to the original owners color . 

a little off topic ,  being i'm as old or older then the truck in picture and brain cells are same as paint on door;;FADED ! question is what is the duct work on right side of hood??? new and improved air conditioner inlet, 😀LOL

look for the obvious first. tracing the cables not only looks for a problem but can also be a learning experience to see what makes the truck run . either way, hope there is a follow-up to let the members here know the end results. was a response given as to the unit having a generator or alternator ?

Didn't all the 24V starting system trucks use the manual push button to activate the series starting circuit?  Seems like all the ones I saw did.  Turn on the key then push the button.  All the 12V starting systems I ever saw just started with the key.

Maybe that's a way to tell if it has a 12V or 24V starting system.

If it IS a 24V start, then that unit would definitely be a good place to start.

I never gave that a thought . All the older series =B's, L's, some very early R's etc had button start. another factor is in the day a key was on/off ONLY. no acc position. key was one wire in one out.  newer key switches gave the acc position  no need for button start . B's didn't need acc position to turn on the AC !

So a while back I posted pics of the beginning of our new firetruck, being built by HME/Ahrens Fox out in Grand Rapids, Michigan. Yes- Hendrickson who still builds crane and heavy application chassis but their main bread and butter these days is firetrucks. I meant to post pix of it as it went through construction but forgot to keep up I mean got really busy with work and family obligations. So here are a few selections for your approval. I mean, it would be nice if you approved but just in case you don't approve I will not lose sleep because I approve. 

First up is the chassis. The frame, all crossmembers and the torque box and outriggers for the aerial ladder are all galvanized. The engine is a Cummins X15 set at 600 with a Jake. (We spec'd a 565 but the offered a 600 at no cost so who were we to say no?) Transmission is an Allison Worldseries (I think an AVS4000) 6 speed. Rear suspension is a Raydan air-bag assist walking beam and Meritor axles and disc brakes all the way around. 

Here is the rear suspension- the Raydan air bag walking beam and the disc brakes. 


Here is Jessica.


The body is bolted, modular stainless steel. Here is the right side. 

 

 

ALL the pictures are fine.. can't post anymore "likes" so my approval is there. the use of disc brakes on such a large unit better in todays world ?? another example of changing technology  i'm guessing. did brakes on daughters car  couldn't believe the tiny little brake pads.

the picture is not wide enough for me...  I think the oil on the spring is coming from the steering box and not the overboard breather..  I bet it runs fine, just needs more frequent maintenance,  if hes not going to roll rods and mains and a new oil pump...  jojo

i second the motion!!  motor oil dripping should have the "wet look". spring had the heavy gear oil (steering box) mix with road dirt etc. i would concentrate on the oil pressure. might be within spec. even oil gotten complicated. and $$$$$  . wifes car runs 0-20. who the hll ever heard of 0-20. higher vis oil might help the pressure on this unit with shorter intervals . nothing else shorter intervals might show improvement. no improve go back to 200 + hrs.

looking at the first picture, doesn't  seem to show the white milky color on the cable or spring assy that would  indicate coolant mixture . post also didn't say using coolant , as with many post, not being there to physically observe challenges. inside of vent tube should have milky film. i've seen brand new trucks with blow-by. not saying it's ok just lesser of the two evils.

what type of maintance are you doing to it  in terms of oil change intervals?  blow -by not an issue . possibly shorten the oil change interval  up grade oil type with hopes of raising oil pressure.

don't remember for sure ,  i think on those "new trucks"LOL  ground  cables go from batteries to frame rail. at engine area short cable goes from frame to  starter.  not like older units that ran a cable  entire length from  batteries to S/P switch. corroded cable end behind battery box usually first place to check. enough of  connection  from frame and cable too get very little voltage    possible

back to original situation, i would consider a faulty S/P if all cables are ok. NO  S/p switch just two sets of batteries; a connection seems likely. a cable ::1 would still carry voltage; 2 - putting a charger on it  shouldn't make a difference  having a bad cable . power can go from charger to starter, should go from generator/alternator to battery set .   was a voltage check done at both battery boxes AND off the gen/alt output. 

all right answers ; just said in different ways. two 6's per box cabled together in series  + of one to - of other equals a X factor= 6x2=12volts per box.purpose of series parallel  switch  take the four  big sixes(12volts each per set) put the two sets in SERIES making it 24 volts to starter ONLY. the unit should be 12 volt positive ground. does it have a generator or alternator??? one set when a S/P switch involved always gets less charge not that noticeable like your though.   with all the new stuff today 12 volt start . batteries parallel to each other + to+ to + can go on endless no matter how many connected its still same voltage. 

A '59 B61 was it converted to negative ground. you stated the neg goes to starter ground. positive ground was common then

If I remember he posted a while back something about he was building air and the air built up and the selector valve was in gear and messed something up in the transmission. Must not had it in neutral 

must be me and old school way of thinking. when ever someone started a truck with manual trans, always push the clutch down and check shift lever for neutral so clutch pedal could be let go. not condemning  any situation ; maybe 15 speed was in stock . never had air problems with the quad.  i know it's just difficult to accept these new air transmissions and many other "advancements". but then the all manual trans have short comings (rarely).

while 3 possible buyer watched ; myself and another mech  were in the process of tow-starting a H67T one cold day . he had the wrecker, i had the H67. -with a twin stick duplex. no air built up and only a hand brake (found out it didn't work) . he stopped quick i let up the clutch-- BAM  right into the boom of the wrecker. point is ALWAYS make sure both sticks are in gear, compound was in neutral  LOL

might be interesting to hear the meaning behind "I broke my 1070 12speed. " misuse , old age , bad shift ????? . 12 speed broke   what's stopping the 15 from  breaking after all the change-over. just wondering . i know things break; that;s what kept me with a pay check for 50 yrs.

I'm so sorry...  I have only done 3 bull gear replacements, and yes it is a big, EXPENSIVE job.  the last one I did was in a GU rolloff trash truck.  I pulled the engine on that one. I also had to do a harness, rods and mains, and a valve adjustment. So I decided to pull it..  When my servivce manager got back from training and saw the engine on blocks, he flipped out and looked at me and asked what was I thinking, and said we dont need any Mavericks here..  I just finished my work, and when the time came to test drive the truck, I didnt have to go back and re-fix a damn thing..  anyway, a bit off topic, just wanted to share some history..  jojo

it's amazing how there are those that put time vs quality on a job. do it right the first time makes more sense ; then there won't be a second time for the same situation.

Get this I hooked up one of my welders and started playing with a chunk of sheet metal burning holes thru the steel and overbeading and lotsa rod sticking spent alotta time messing around pretty quick i noticed I was getting addicted to this and couldn’t put it down until I got it somewhat together lol going out this morning to have some more fun .. also noticed the more I do the better I’m getting at it…Bob

i said many times i'd rather have a welder in my hands than wrenches. no limit to the fun and experience working with welding. in the days of my small shop, i had 5 welders. from a little 120 wire feed . two 220 buzz boxes, 1 wire feed and the big lincoln I mounted to an air compressor   chassis and towed behind the F 350.   as discussed in another topic;;;;DON"T forget ear plugs.   i always wanted to spend more time with a TIG machine, there was one in plant maintenance where i worked, never enough free time

I'm looking forward to getting back in the shop to start working on the sheet metal but it's too cold.  It's 32 degree's and a 20 mph wind. I guess I'm getting too old. 

Your not getting too old  it's just time is going by too FAST.

i like the "Perfeshaminals" that have to shift every damn gear in an 18 speed.......bobtailing. 

 

a short version of a comical story. years back working for waterbury Mack, we took two new trucks to new haven truck rental ; picked up two for warranty work ,  i took the DM611 with quad heavy 24 in rubber frame rails half way to center of the radiator  R model other guy had. he was behind me pulling out of driveway. unfortunatily i have to mention he was half shit housed from the beer he bought on way down. point is i was still teaching myself the proper way of shifting a quad, no brakes coming to stop sign;; downshifting instead. dopey behind me didn't see brake lights  - he put the DM frame rails into the R's radiator.  so there comes a time when shifting ALL the gears has a side disadvantage. LOL

O&G should be over this by now. May be they are and they just don't care for the Volvo product.

 

If the old timers were still involved with the purchasing at O&G  Mack might have stood a chance in todays world. we all know new england hasn't been Mack country unfortunately for yrs. you should have seen the look on my bosses face when i delivered the new DM to O&G. the guys were trying every way to open the hood. i walked up and  said" guys hold on this isn't a horse on the hood it's a bulldog. every part of this truck is functional. " i walked over grabbed the bulldog and said " you pretend this dog is your boss, put your hand around his neck and pull. " thought i was going to be fired on the spot. think i was saved due to the large amount of laughter. all honesty, would you consider a mack today over other brands?
