Re: [diesel_mercedes] Exhaust and Fuses

 

Hey Brian,

You may already have the answers to these questions, but:

I've found the exhaust pipe coming off the turbo pretty easy to manipulate.  I always remove the nuts and bolts holding the pipe clamp holder assembly at the transmission, though.

On my '79, the 2A fuse was in the yellow stripe inline housing.  My green stripe holder had a 10A fuse....

Can't say I've ever encountered a glow plug light that wouldn't go off.  Maybe the timer has gone bad in the interim?  Is there power getting to plugs?

Subject: [diesel_mercedes] Exhaust and Fuses

 

On the 5 yard line with the '79 300SD redo as mentioned Sunday. A few issues have popped up and I'm in need of a helping hand.

1. Exhaust. What is the (*&^%$# trick to hang the exhaust back on the turbo. Dear God...I may lose a finger on this one. Not having a lift is making matters worse. Do I need to mount it to the turbo first then shore up underneath at the trans tunnel support or set it first on the support then try to wiggle it up? Also, is it easier/preferred to hook up the mounting clamp and the connector to the turbo or to the exhaust?

2. On the W116 SD, in addition to the regular fuse panel, there are two fuse links (wires with glass fuses inside them). One is a 2amp, the other 5amp with the former being for the Automatic Climate Control (ACC) amplifier and the latter being for the Aux Water Pump. Finding the fuses has been the Magical Mystery Tour. My question is which is the 2amp and which the 5amp. One has Red w/green stripe on the wire, the other red w/yellow stripe. No, the fuses are not in there now :-)

3. Hooked the battery up for the first time last night and for some readon the glow plug light stuck on, never went off. Did not do that before the project. Not sure WTF is going on there.

Yeah, that was the original plant in Livonia.  The fire occurred in August of '53, and everybody scrambled for automatics; Cadillacs and Oldsmobiles got Buick's Dynaflow, and Pontiac got saddled with the original Powerglide from Chevrolet.  Nine weeks after the fire, the new plant in Willow Run was up and running, so everybody was getting trannys again.

Rolls Royce was in a good position; they were building Hydra-Matics on their own under license.

1954 was the last year for the original, efficient Hydra-Matic.  For '55, a second fluid coupling was installed, in place of one of the clutch packs, to smooth out that 1-2 shift lurch.  Combined with some engine changes (including a displacement increase), Cadillac Series 62s, for instance, went from fuel mileage in the low 20s to the mid-teens.  I don't know if the trucks, which used the Hydra-Matic til the mid-'60s, long after the cars switched over to the Turbo Hydramatic 350 or 400, ever got the dual coupling unit or not....

Agreed ! . this was a _fabulous_ transmission and way before it's time , it was used behind L6 engines too to great effect in millions of Commercial Vehicles as it had a 250,000 mile minimum service life.

Fuel efficient too .

Sadly , GM placed ALL their Hydromatic eggs in one basket and when that lone factory caught fine & burned to the ground , that was it ~ they couldn't supply them to FoMoCo for the Lincolns any more , nor the Indie brands that used them .

More's the pity .

Re: [diesel_mercedes] Re : GM Dual Hyr

 

Except on the original Hydra-Matic, the rear band required pressure to RELEASE.  Also, the front and rear pumps worked independently of each other.  (In fact, the front pump was variable output, and had negligable effect at speeds over 40 mph.)  If Brian never slipped the car into Neutral while coasting, he may have been able to get away with his stunt.  But, once the engine was stopped, pressure to the rear band would drop.  Going back into Drive would get the engine spinning again and the band would release, but only after the forward momentum and weight of the car had to overcome the friction of the applied band, which would take up to five seconds.  A few cycles of Neutral/Drive/Neutral/Drive, and that band would get pretty hot.

Also, they didn't have any sort of fluid cooling, other than whatever was cycled through the fluid coupling, which was minimal in the higher gears.

BTW, Mercedes transmission models 722.0, .1 and .2, the ones with the four-bolt oil pan, used up til '81-ish, retained the rear pump, and yes, ARE push-startable.

(Wow.  Got this back around to Mercedes....)

Brian,

I don't think you should think it is your fault.  The original Hydra-Matic had a rear pump.  It should have been able to deal with being operated without the engine running.

(Reality note - since about 1970 ? auto trans have not had rear pumps - they cannot be towed or operated with the engine running.  Most earlier trannys had the rear pump so they were less touchy.)

Re: [diesel_mercedes] Story Time Again (Topic Drift , delete now or don't complain)

 

Yeah, the gear selection was not the "PRNDSL" that's been Federally mandated since the mid-'60's:  It was "NDSLR", the reasoning, so the story goes, was to allow quick access between Low and Reverse to rock a stuck car out of snow/ice.

There actually was a parking pawl that would lock the output shaft when the engine was shut off in "R".  That, and the rear band needed pressure to RELEASE (just the opposite of every other band in all other transmissions) meant that transmission was pretty much locked solid once the engine was off.

(And that rear band is probably what got toasted on Brian's Oldsmobile, among other things....)

  I had a 1954 Pontiac Super Chief Coupe , it was a terrific car with InLine FlatHead 8 cylinder engine and a Dual Hydromatic tranny .


It has warped & burned valves so *very* low compression but once I got it started (that was always the trick) it ran just fine and went like stink , handled nicely too .

For those who do not know , back on those days , the GM Hydromatic automatic tranny didn't have a " Park " gear , what you did was to shift it into _reverse_ when the engine was off and the reverse gear slid over and locked up the driveline tight .

Enter poor 16 year old Nate and his latest saved from the crusher car (it really was a beautiful car !) , with this tranny and bad valves , I'd be backing up and looking over my shoulder as the engine chug - chugged along @ 350 RPM's or so , occasionally it would stall and then I had about four seconds to turn around , grab the shift lever and work it all the way back to Neutral or Drive before the tranny locked up with the 4,000 Lb. car still rolling backwards @ 4 MPH or so , this of course made the old tech Bias Ply tires skid and screech not to mention whipping the soft GM 1905's suspension to it's limits a few times, nearly snapping my neck in the process.....

Oh , those Halycon days of youth long gone past....

And herein lies another sad story. When I was a young 16 year old boy with my 1950 Oldsmobile Club Coupe, and being poor and frugal - I took my car up to Mt. Baldy for a day in the snow. With the gas tank at a 1/4 tank or so for the drive down the mountain, I thought I would save some fuel by turning the engine off and come down the mountain using the trannie to slow me down. Well, it was several weeks later when the trannie went south on me and gave up the ghost.  I was going to convert over to a LaSalle stick shift anyway, but I admit, I was a foolish and stupid young boy at the time.

Re: [diesel_mercedes] Re: The Frankensteining of Great Cars

 

That's right!  RR was actually making them in England under license, and so had the opportunity to make modifications.  My father told me that story eons ago.  I just wondered if it was really true....

I remember reading that RR destroyed a few Turbo-hydramatics by polishing the interior  channels, which were designed to have  irregular surfaces to create turbulence in the fluid.

Actually, the association goes back much before the Turbo Hydramatic 400, to the original, 4-speed Hydra-Matic of the early '50s.  In my opinion, an even better transmission; the only automatic battle-tested in World War II, four of them were installed in the little M24 "Chaffee" light tank.

(Hydra-Matic was also used by Hudson, Nash, even arch-rival Lincoln.)

[diesel_mercedes] Where's My Whip ?

 


I drove SWMBO's nice 84/85 300TD to work to - day , the right rear window stopped closing all the way shortly after I purchased the car , after work I took the right rear door apart to discover the motor & lift assembly were missing hardware holding it to the door frame , this meant the motor was over torqued severely and the cast aluminum bracket is bent like a pretzel....

Lucky for me , Rich had a set of spare doors and he sold me one so I had everything I needed to set it right again .

I cleaned off all the old gritty dirty grease , thanx to the DPM who'd mangled it before and left the plastic dust sheet out..... I cleaned out lots of dirty grease & re lubricated everything with White Lithium based grease then I cleaned the dust , leaves & misc. debris out of the inside bottom of the door before closing it back up again , as soon as I find a plastic sheet , I'll dip back in and repair the vacuum door lock the seal it up nice and tight .

Mercedes kindly made everything in the door adjustable , rather easily and even the lower rear window guide is simple to remove , this makes door service not the usual nightmare I hate .

There's a big round crash protection bar running front to back inside the door , nice work Mercedes ! .

Some people really should not be allowed to touch either tools nor Motor Vehicles ~ I'm flabbergasted they _PAID_ someone to beat the crap out of a helpless little Station Wagon .

He needs his butt kicked really hard .
