Re: [MBZ] ML550 Starter

[Allan Streib via Mercedes]

Working with the lathe wearing long-sleeve robe-like clothes was eye-opening.

And the bare feet/sandals in the shop

I saw a kid drop a 25-lb weight on his foot at the gym. Split his toe open, and 
he was wearing shoes.

Great little video... I didn't see the OSHA inspector doing his mandated
walkthrough safety inspections... and I note that all the workers have
their safety protective equipment in place, as well...
High pay, short work days, union shop, with good health insurance, I'm
sure..

Thanks for the pics
The planetary gear set grease is certainly "well used" isn't it.
It looks like the design is programmed for failure.

There are videos on YouTube showing how these starters are "rebuilt." 
Basically, with a few hand tools and can of spray paint, in a dirt-floor shack 
in Pakistan.

Starters are un-fused.  I think they always have been.
Something about it being difficult to put a fuse on something
that draws 1000A+ (briefly) and settles down to 200-400A
during normal operation.

If the starter was being fed by Grand Coulee Dam, you'd still
need a fuse.  But the battery feeding it will exhaust itself before
it could catch the starter wiring on fire, so the primary purpose
of a fuse is unnecessary.

Also, depending on exactly what/where the shorts are, starter
current merely goes up, as does internal heat generation, while
starting torque goes down.

And, if the shorts were causing the starter pinion to not engage,
the massive current normally induced by the torque load on the
motor is not there, so the starter's drawing much LESS current
than normal.  So, no fuse action even if there was one.

So, attempts to make it smarter, in this case, are likely to be
counterproductive.  As my boss is fond of saying:  "IBM".
(It's Better Manually.)  Don't try to automate stuff that doesn't
really need it.  In the case of a starter, it's pretty simple:  Does
it crank?  If not, fix it.  The diagnostic process is simple, just
one current test and a couple of voltage checks and you have
your culprit identified.

Because Grant put the idea in my head to do some failure analysis, I had a 
couple of minutes to spare so I tore into the failed starter. I’l post some 
pictures in a little bit, but suffice to say I was surprised!

It does have a planetary gear set that’s internal, which was pretty cool. Based 
on what I saw, the front edge of the armature windings were rubbing against a 
metal spacer or cover between the armature and the planetary gears. So much 
wear that the varnish was worn off the windings, meaning they were shorting 
out. I couldn’t determine what had caused the end play in the armature to allow 
it to move against this plate, but it’s clear that was not a good thing.

I couldn’t get the solenoid off of the main casting, as the phillips head 
screws they used were driven in with an impact or may have had thread locking 
compound on them. I’m pretty satisfied that the armature was shorting to 
ground, causing enough of a voltage drop that the solenoid wouldn’t pull in, 
letting the motor freewheel with the armature rubbing the metal plate, which 
was the source of the noise I was hearing.

Re: [MBZ] ML550 Starter

[G Mann via Mercedes]

Congratulations on your success...
It would be interesting to do a teardown on the kinked starter and see what
failed to have it lock up..

The 642 is shorter so less room I would assume requiring the mount to come out.

Re: [MBZ] ML550 Starter

[dan penoff.com via Mercedes]

Starter has been replaced. Huzzah!

I took my time and spent some time fiddling with moving harnesses around to 
gain (better) access to mounting bolts while doing this in the middle of my 
driveway. I would say it’s an hour’s work on a lift. On my back in the driveway 
added maybe 30 minutes, as well as having to walk over to the garage every time 
I needed something.

No need to drop/move exhaust. I didn’t mess with the engine mount, either. With 
the starter mounting bolts out, you can move the starter around to the point 
where it is pointing straight down and out the opening. I brought it out 
terminals first so I could remove the wires, then put it back up and flipped it 
over. I would liken it to removing or replacing an ETA (throttle body) on an 
M119 engine. There seems to be a lot of room, but there’s only one way you can 
turn the ETA for it to clear everything.

Not original - a Bosch remanufactured starter. Hmm. I haven’t looked it over to 
see if there’s a date code or something to try and figure out how old it is. 
Attempts to turn it by hand were not successful. It’s definitely borked 
internally.

Orienting the lead to the solenoid is not fun - it sits precariously close to 
the engine mount heat shield. Lots of cables and stuff in the area aft of the 
starter which can prove challenging for getting at the star head starter bolts, 
but like doing a starter in a W123 as I recall, a bunch of extensions and 
swivel joints are helpful. Getting the bolts started back up wasn’t difficult, 
although the bottom bolt seemed sort of tight. I took it out and looked at the 
threads, which were OK, and just figured the tolerances must have been off the 
day they cut those threads. It cranked down just fine all the way.

Car started right up and was able to drive it into the garage. Time to cool off 
then have a shower.

Re: [MBZ] ML550 Starter

[dan penoff.com via Mercedes]

Will do.

If there’s detritus in the bellhousing it should be at the bottom. Unless the 
starter remained engaged and went overspeed, which I doubt because I never 
heard anything indicating a failure) I suspect an internal failure and no 
shrapnel. I hope.

I’m going to go out in a little while and drop the belly pans and have a look 
at things in general.

Post removal teardown should be "interesting" to see what exactly failed.
Please let us know what you find... and if you find all the bendix parts if
it came apart inside the flywheel cavity... [worst case, not likely, I
think]

No joy. It sounds like the bendix has completely failed. I’m not getting 
grinding sounds out of it, I’m getting no engagement and a sound that’s like a 
coffee can full of nuts and bolts, which I expect is the remains of the 
freewheeling clutch in the bendix.

I’ll be tearing into this tomorrow unless the weather is bad (don’t think it 
will be) and I’ll know more at that point.

Re: [MBZ] ML550 Starter

[G Mann via Mercedes]

Jack up the car, high enough to gain access to the starter, [use
jackstands so you can get under it safely... Once in position, give the
starter a good smack with a good size hammer.. Then try engaging starter
again..
If the starter bendix hangs [and they do] it will fail to extend far enough
to engage the flywheel ring gear, and since the gears don't engage, give a
gear grinding noise...
If, after the hammer whack, you get engagement, move the car to where you
want to work on it, to remove the starter and repair the bendix [clean and
lube with never seize so bendix moves freely.. or replace with rebuild,,
your call...

Check out the W221 forums. Won’t have the nuances of your car but a 4matic 550 
would probably be about the same

[MBZ] ML550 Starter

[dan penoff.com via Mercedes]

Went out to Lowe’s to buy some landscaping stuff for the yard. Backed into the 
driveway to unload. Got back in the ML550 when I was done, hit the start button 
and got a medium pitched squealing/grinding noise. Ran the Chinese scanner on 
it and found nothing. Did a “listen” test while oldest son hit the button and 
it’s definitely coming from the starter.

Almost nothing about this on the Internets. I found a few references to the 
W164 V8 starter in online forums, but nothing of substance. There is a YouTube 
video of the job but it’s potato cam stuff and the guy is a hack in that he 
took a Sawzall to the exhaust.

I’ve got to fire up my computer with the WIS, but it appears that the exhaust 
has to come off to access the starter. I’m hoping that’s not the case, as this 
isn’t the sort of work I want to be doing in the middle of the driveway…

On the positive side, at least it puked in the driveway!
