[diesel_mercedes] Heater Blower Repair

 


Dang cheap German cars ! you'd think being in the land of cold & snow , they'd build a decent heater but Nooooooooo ~ after only 28 years and 281,000 miles , the brushes wore out and it stopped working =8-^ .

I ordered up new brushes from Kent Bergma @ Mercedes Source in Bellingham , Wa , removed it and began the fun ~ as this car had been completely filled with dense choking clouds of Diesel smoke (oops) , it was pretty nasty in there , I took some pictures of the cleaning and repairs , Tom was busy to - day so I didn't get pix of the important difficult bits but I will when we overhaul his fan motor , I have a lead on affordable brushes working now , IIRC Kent gets $9 , not bad but being able to get them locally would be nice .

Sadly the commutator on my motor's armature wore at an 4° angle and I thought it beyond salvage but it works just fine and the new brushes should wear in fairly soon .

Most of the work was the cleaning ~ whew ~ that took patience and diligence but was worth the effort ~ electrical devices don't like heat and dust covering everything is a dandy insulator .

The commutator end bushing is the self aligning typ ~ a very nice touch , I put three drops of oil on it but it may well be designed to run dry , I can't tell but it spins freer now .

[diesel_mercedes] Fan Motor Repair

 


Dangit ! .

I had a long detailed message about fixing my fan motor to - day but the 'puter ate it =8-( .

I have fat fingers and occasionally press the wrong key and loose messages .

Anyway , it's DIY Do-able , I got some pix but not all I needed / wanted , there's a few tips Kent's How - To Booklet doesn't cover and I want to make a tutorial , when Tom brings me his dead fan motor I'll have him take more pix and create an album .

It's nice to have the fan again , even with no AC or heat on , I like a strong breeze of fresh air all the time and opening the window is too noisy .

Rotten leaves & walnut shells ~ I guess they left a window open in a car port or open garage....

It's been a while since your last report , how's it coming along ? .

Re: [diesel_mercedes] Junkyard FUN !

 

Two things - a) The empty row in Ontario PAP was filled with non 123's, lots of Volvo's, couple of 126 gassers. b) They have installed a computer database near the entry where (supposedly) they can punch in the part you are looking for, and see if they have such a part in the yard. Allegedly this same database system will be in Monrovia and other yards owned by this "PAP."  I went and looked anyway, but on the way out I gave him my specs, i.e., "turbocharger for a 1983 MB 300d" as I did not see any w123 300d's. The mystical database pulled up an "option" which was a 1981 116 300SD turbocharger. I have not cross checked to see if they interchange, but if they do then this database could be useful.

Yesterday Tom came by after work and we went off to my favorite local Self - Service Junkyard as I desperately needed the walking exercise and his SD needs glow plugs (yes , we're poor White Trash who use used hard parts , get over it) ~ I quickly found a _RUST_FREE_ 1979 300SD that still has the European headlights in it , it also had some very new glow plugs and injectors , too bad I didn't have my injector socket .

Then Tom found a complete AS-NEW toolkit in the rtrunk of a W-126 560SEL I'd walked past as I never find any dang tools =8-^ .

He also found the remains of a very nice cobalt bule 1980 300CD , there wasn't much left as this car was clean and shiny , I did manage to get the new taillight lenses off it for a wopping $ 27.98 the paur .

I also found a 1979 W-123 240D with the hard to find black matte finish panel around the gearshift lever , that cost me $4.99 .

It'll soon be cleaned up to look new and join the matching dashboard switches cover on SWMBO's '82 240D as the wood in it is beginning to die and it's easier , cheaper and IMO _better_ to have the black covers as they never wear out unless you break them .

Apparently the Pick-A-Part Corporation was just sold to some outfit in Chicago called LKQ , the P-A-P Employees told me they're being treated well .

Tom got a perfect saftey triangle for $1.00 wow .

After we left , we stopped in a local gas station with good cement and passable lighting , I took my hear blower motor out of the car and part way apart , the brushes are dead worn away to nothing and the armature doesn't spin freely ~ now I guess I know whay the heater alwaysdragged down the charge voltage so much .

I'll soon clean it up and open it up , try to lubricate the bushings and replace the brushes with new ones from Mercedes Source in Bellingham , Wa.

The brushes are soldered into place and the leads should be carefully routed so they can't touch the edge of the whizzing commutator , Fritz apparently wasn't feeling too good in 1984 when they built my Coupe as the braided brush lead has rubbed against the commutator and wore part way through , it's a good thing I'm fixing it .

After washing up in the squeaky clean rest room , I changed my shirt and we went off to a nice dinner @ The Souplantation .
