PostPosted: Fri Nov 23, 2018 5:15 pm    Post subject: Distributor refurb Reply with quote

After reading several threads on the distributor belt replacement I decided as a matter of caution to check mine.
After removing both caps it was soon apparent my distributor was in need of a total refurb.
The secondary shaft had a worrying amount of ‘play’ so new bearings required there.
I was also surprised with the amount of a surface brown dust / rust build up around the inside casing, surprised because the car in all my yrs of ownership has always been garaged, and rarely been out in the rain. So car washing water / condensation must play a major part in producing this rust, and slowly but surely destroying the bearings.
The car has travelled 110k miles and l’ve no record of any past work being carried to the distributor, other than new caps and rotors. So I’m assuming everything was original.
After timing up the engine the distributor was removed, packed up, and sent out to Diddi in Germany.
Diddi kept me up to date with photos as the work progressed.
I’m going to post these photos for you to see the quality of his work, I could not believe the transformation, his standard of work, attention to detail is nothing short of perfection.
The distributor along with new caps/rotors and spark plugs, are now fitted to the car.
I was always impressed with the performance of this car, but now it’s transformed, noticeably smoother, more responsive and just sounds a whole lot better.
I am one very happy 993 owner and I owe a big thank you to Diddi.
If you need to go down the route of having this work carried out, I cannot recommend this guy highly enough. Superb.
Thank you to Endoman for the recommendation in the first place.

Would you be willing to share the contact details of your refurb man and also give an indication of the cost?

Its on my to do list.

Cheers

Diddi is a member on here, his email :- D964@gmx.de
His work is of the highest standard, he gave me a quote before sending the unit to him, he had to carry out more work than he first thought, and to be honest, I think I knew that would be the case when I remove the unit.
Having said that, he was still prepared to honour his initial quote and I was more than happy to give him extra towards a charity of his choice !
Email Diddi and he will be happy to quote for you.
One warning I have for you, and anyone else....DO NOT use DHL, I had a nightmare with them, read the reviews, I wish I had.

well worth doing, a very cost effective insurance job, given the risk of failure.

Very true, I think the bearings would have failed before the belt.
Think I’ve been lucky on this occasion, here’s a pic of one of the bearings.

He has, considering everything is new it should last a few yrs before needing anything doing.
If anyone is thinking of having this work done, the distributor isn’t going to pull out of the engine without a fight (unless you’re extremely lucky !) a little tip to getting the distributor out (once the engines timed), use WD40 or similar and spray round the base of the dizzy shaft, I then put a strap under the distributor body and pulled up on that, you get far more grip than just trying to hold the dizzy body.

What do you mean about ‘timing’

You need to line up the engine timing marks before you remove the distributor, the idea being when you put the distributor back in, everything is in exactly the same position.
There is a timing mark on the crankshaft pulley which you line up with a mark on the engine casing, if the rotors on the distributor are lined up with corresponding marks on the dizzy casing, the engines at TDC.
Hope that makes sense, and i haven’t taught you to suck eggs

Hi Diddi,
Thanks again, appreciate the great work. Next time it’ll just be the belt to change !
I put this job right up there with the other jobs to check on these cars, the chassis rails and engine wiring loom.

Jack D[/quote]Thanks for the clear explanation. Sounds similar to my 1964 Land Rover where I’ve removed and replaced the distributor without a
problem. I will give it a go - so far I’ve done no maintenance on the 993, having left everything to Cameron Sports Cars in Bath to handle. The only thing I’ve done so far is buy the Bentley manual. It needs to start earning its keep

Hopefully the link below will work.
I was going to attempt the work myself, Replacing the belt is doable, but I knew more was needed, and to be honest, when there’s people like Diddi who can rebuild these with his eyes closed, why attempt it ?
His costs are more than reasonable, just look at the cost of refurb units from eurocarparts, design911. It’s a no brainer.

What's the best way to get the dizzy out? I've tried an impact puller with a strap but no joy. Glad I didn't wack the secondary like that.

Either pulling helps and shaking back and forth, or one helps with light blows, e.g. with a rubber hammer, until it "comes". Attention: The distributor housing is die-cast and not really resilient. In case of brute force it will break or tear. So: patience! I

spray with WD40 (2 days before) beforehand also helps !

or use a screw clamp - place the angle under the DZV and tap on top - always with Feeling !
