Re: [diesel_mercedes] Re: Vacuum Leaks

 

Nate,

I bought the Harbor Freight imitation of a Mity-Vac - it was $15 cheaper.  It seems to be better quality - brass and steel, rather than plastic.  I have not used it on my MB, but on other projects it has performed as expected.

<http://www.harborfreight.com/brake-bleeder-and-vacuum-pump-kit-92474.html>

<http://manuals.harborfreight.com/manuals/92000-92999/92474.pdf>

My prior Mity-Vac went bad when I got gas in it.

<http://manuals.harborfreight.com/manuals/39000-39999/39522.pdf>

I seem to remember the Mity-Vac could be re-arranged to do pressure as well as vacuum.

O.K. , go buy a "Mity-Vac " (brand) tool and 25' of the _correct_ Metric sized vacuum hose and some golf T's too ......

A new pair of good quality Dykes too , not those $1.50 ones from Harbor Freight .

[diesel_mercedes] Re: MPH & Fuel Economy

 


That figures ~

I begged you before and now you want rid of them .

Be aware that all these little Motos get terrific fuel economy but , the Scooters , by design , are deadly machines , mostly due to the tiny wheels .

I love old Tiddlers , especially old Honda 90 & 125 C.C. ones , they're perfect for commuting and long distance touring too as they have 17" wheels and good seats .

Yea, I've got 38mpg and 37 mpg on two tanks before. Untill I figured I must of screwed something up in my figuring. Max

I run 4 psi over max inflation,gives better mileage and tire wear.

Couple other factors that may play in.

Correct tire preasure with the new tires, a bit low with the old ? Do you check it often ? Also tale a look the DOT ratings.

300-AA-A vs 700-A-A the Nikians are rock hard, a lot less rolling resistance.

The other thing is, you need to chek the milage over a couple tanks, as there is also the placibo effect, maybe you where paying more attention to your driving habbits due to the new tires and did not realize it.

[diesel_mercedes] Re: Back in Good Hands

 

Nate,

I would love to have that post if you can find it again. I am going to need that kind of help.

As you may recall, I put the car in this guys hands initially to fix the AC, which he did by changing out the compressor, evaporator, ect.
But, the vents did not work do deliver cool air and that is when he decided to pull the dash. I have to think that is where my problem is.

Other work that he did was to replace the starter, radiator, center bearing and steam cleaning the engine.

As I had stated before, the car was running great when I took it to him. He actually returned the car thinking it was finished to a friend of mine in NC, who had driven my car before. It was then that my friend called to tell me that the car was not right and had no power. The car then went back to this guys shop to be fixed.

He kept trying things to fix the car. Apparently the transmission was not shifting correctly and he replaced some vacuum devise on the transmission. Again, the transmission has always worked fine on the car up until now.

As last I talked to the guy at the garage he was having trouble getting my car to shut off. It has done this before with me as vacuum lines came loose but that was always simple enough to fix.

So....it seems to me it has to be in the vacuum system. I'll know more in the next few days when I get my car back. At that point I will certainly update you guys and be asking for lots of help.

There is this German garage here in Houston that works on nothing but old Mercedes diesels and I have been in to talk with this Austrian guy who was trained by MB at the factory. No question he can probably fix this, but I want to have a go on this first myself.

Thanks in advance to the board.
