Thread: 300tdi Aircon clutch wires repair

From what I can find out you cant remove the clutch unless you have a special puller to get it off, and installation tool to get it back on :-(

Is this something that the average auto-electrician would be likely to be able to do?

Alternatively, any suggestions on where to buy a puller to do it myself?

Steve,

I have nevwer had to use a puller with these, just remove circlip from memory and pull the clutch off. I have had success repairing these wires on many occasions, cutting back into the insulation reveals enough usually to solder to.

This cannot be done with Tdi Defender type Sanden compressors, only the Nippondenso Disco ones, as the Sanden compressors clutch isn't removable without degassing etc from memory.

Thanks Justin - that's what I wanted to hear

I'm confident I can repair the wires once I get the clutch off and have some decent access.

Just had a similar problem currentley on the road driving to Qld and was able to use a wire joiner as a quick fix until i get a chance t o solder it, Fyi

Well, it was easy to get off:
1. Remove the bolt holding the drive flange on
2. Remove circlip retaining the pulley
3. Remove circlip retaining the clutch solenoid.

The soleniod is just a sliding fit, but has a dowel to prevent it rotating.

Looks like its going to be a bit more difficult to solder back on than I thought. The belt has worn away about a third of the connector block. One wire has enough to solder to, the other I'm going to have to file away a bit more of the block to get somethign to solder onto:

done a few jobs like that in my time and I try to build up around the new joint with a bit of epoxy or such like stuff, I believe it makes a more permanent job as it reduces the stress and vibration on the new joint

All back together now and working fine.

I didn't use epoxy, but I did put a decent blob of silicon around the new joint once it was all back together. Should do a reasonable job of supporting it. I managed to pick away around the broken contact and get a good solder joint so I'm pretty confident it will be OK.

Hi all,

I did exactly the same thing with mine a couple of months ago, I removed the part and took it a good mate who can solder. After refitting I can't switch the a/c off, I tried reversing the wiring but it still ran on, I must have left something out when refitting: however I was really careful and thought I did it right

Can anyone help me out with this please?

Regards to all Jim.
