[MBZ] Walmart Lesson - Plan Ahead

2018-08-28 Thread Scott Ritchey via Mercedes
The 5-year old Group 26 battery in my standby generator died.  A little on-line 
shopping showed Walmart had them, in stock, for about $50 but the price was $80 
when I got to the cash register.  If I had bought online (for $50) I could have 
picked up the same battery at the same store and saved $30.  In fact, if I had 
been thinking faster, I should have cancelled the sale at the register, bought 
online with my cell phone, and picked up that same battery.  I had no idea 
there was such a disparity between online and store prices.

Not for the mix, so far as I know.  But propane is R290, and isobutane is
R600A.

That looks like a /8 (and from the date, it should be).

Re: [MBZ] White Whale Plan of Attack: Weak AC

2018-08-28 Thread Scott Ritchey via Mercedes
The mono valve has a replaceable element (called a lifting magnet).  When 12v 
is applied to the coil it closes the valve to stop hot water flow to the heater 
core.  In normal heater operation, the HVAC switches 12v on and off to regulate 
the temperature.  In cooling mode the coil should get 12v continuously to keep 
the valve closed.  The insert has a rubber diaphragm that can fail.  Also, use 
of coolant leak stopper can mess up this insert.  Normally, only the element 
fails and it's not hard to replace but it may be hard to find a new one.  I 
think MBZ recently made a new batch, going for about $50 each, as I recall.  
They were much cheaper back in the day.

Heater will always overwhelm AC.  Someone put a manual valve in the heater hose 
on my 300TD for that reason (always closed in summer).

It's a rare turbo with a very rare 5sp conversion. 
If it's rust free (seems to be) and everything works, it'd be great to have 
with good paint and seats. 
Alas, the paint is fried, and the seller seems to be reluctant to give us a 
good picture of the driver's seat. Which explains why the CL ad is 22 days old. 
Maybe Karl could pay it a visit and entertain us with the full story of what 
was done to this car over the years.

Testo manifolds are good too.  Fieldpiece has a nicer controls and displays 
(IMO) but Testo units are more compact and some have Bluetooth for remote temp 
sensors and smart phone interface.

I need to check but I doubt these units have pressure-temp curves for 
Envirosafe.

Going back to the White Wale, I think temp measurements at both refrigerant 
lines will be needed to know what's going on.  Automotive systems are 
complicated by the fact that the variable compressor speed and variable air 
flow/temp across the condenser coil.  Still, using the ES pressure-temp data it 
should be possible to see if the refrigerant is condensing to liquid, say at 
idle.

Here's another weird data point that may be a clue.  After sitting at idle
for about 30 minutes I finally get my daughter in the car / buckled up and
then back out onto surface streets so the engine speed can climb a bit to
2500 RPM or more, for the short accelerations between shift points.

Vent temperatures have gradually climbed while sitting from about 60 to
about 75 deg F, and once I get started moving (rise in engine RPM) the vent
temp briefly drops down a bit and then climbs way up to 100 deg F or so.
Fan blower is on maximum speed setting the whole time, lots of air moving
over the evaporator, and the electric cooling fan on the front of the
condenser is doing its thing, cycling on and off as needed.

Could this be explained by a refrigerant that is mostly propane now, or do
I have some problem with the thermostatic expansion valve (TXV), or ???

I'm pretty sure the TXV is not the original R-12 compatible TXV that came
with the car, so maybe it is trying to regulate for R-134 referigerant
which has a different pressure curve, and so it is flooding the evaporator
with too much referigerant in liquid form (hot liquid form) which spikes
the vent temperature.  This might also explain why at lower engine speed
(lower pressure on the high side of the compressor = lower pressure into
the TXV) the vent temperatures are lower than at higher engine speed, as
observed earlier.

Whose got a NOS TXV for a 124?

Beru, that's the "good" brand.  Bigger beefier "nut" part, and Beru
publishes a maximum loosening torque of 45 Nm IIRC.  I could find no such
torque published for Bosch.

Bosch are not as good as the other brand that I can't remember the name
right now.  Bosch was not the factory installed glow plug in the OM606.
