Hi all,

W123 300D 1980. I pulled the motor body off the fan body to clean and re-grease. I didn't look carefully enough when I pulled it.

When I was putting the motor shaft/body back onto the fan body I wondered if there was a washer of some sort between them so as to not have metal fan spinning against motor body metal. It looks as if there should be but I don't know. Can anyone help advise? It is the bosch type motor.

Thanks

There is no washer, if your fan is rubbing against the motor....you need to pull the fan up a bit and tighten the Allen head grub screw....

Thanks cooljay, much appreciated.

No prob, have you done any of the other repairs to your evil servo unit?

Do you mean by the servo unit the push button controls? If so my car is a euro and only has a dial for the air con and sliders for the vents. I need to do the whole air con system but that is another day in the future. It works but only poorly with an R4 compressor. Will install new hoses and check the adjusting screw for compresssor cut off on the air con dial referred to above.

Yes that is the one, well your lucky you have a euro and don't have to mess with an evil servo. Though it is truly a fun experience yes my ac is in my future to do journey too....my list got to long so I switched to a journal lol

Putting the backing plate on the motor housing and the little metal lug parts that bend over and hold the plate wont grab the outer edges well enough. I must have been too forceful in pushing them back.

What do I do? Soldr if possible, use Oz equivalent of JBWeld? Suggestions please.

I worry if I use JBWeld vibration over time will break join but don't know?

I doubt jbweld would work on that...seeing as all the weight of the motor rests in that once installed and then when it spins...

You may just have to spring for a new motor....when I was looking they were only a 100$...

Thanks Cooljay,

I got advice to build up the damaged burrs with TIG weld then reburr them over as original. Failing that, make up a bracket that screws into the body holding the plate on. I have a spare already but want to see if I can succeed with this first. A challenge I suppose.

Cheers

Hi cooljjay,

I struggled to find a local doing TIG welding that could fit in with work time etc so I went with a metal putty that has carbon fibre as a strengthening agent. There appears to be enough surface area over the whole baseplate to bond it securely. To add to the strength of the baseplate bond, when the metal motor housing is inserted into the plastic fan housing body, this plastic body is bolted onto the metal baseplate. The motor housing also sits snuggly into this plastic housing. This will reduce rattling vibration so the bond should not likely crack. If it does I will post back and say this is not a doable method.

Cheers
