Small jobs now but they will take time e.g. A headlight screw that won't hold as the thread on the tab is worn out. Plenty of options on the Net but I'm not sure which way I will go.

I wonder if we could try and put a heli coil in that headlight tab, I have a set at work.

Apparently the best option is to drill the hole out to 7mm and fit a rivet nut.

A slow weekend on the refurb as I had places to go and people to meet. To keep things moving I cleaned the carpets and seats (one is modified to have my 6' 4" frame fit with a helmet without touching the headliner), plus fitted a banner for the upcoming Porsche Festival. The interior is not much changed from before. Mod 07 wheel, Cobra seats, techequipment gear **** and handbrake.

Rivet nut and tool sourced however I have to get the 7mm drill to start this.

Specialist Components ECU in place and the vacuum reservoir has been fitted to a simple L bracket bolted to the stub from the removed air filter. That's 20hp back where it should be.

Looking good John, can I ask, what finish are your RSR seats please?

Vinyl and fabric (Corduroy style). I bought them locally in NZ so had no real choice. They are holding up quite well, but I would have preferred a better quality fabric at least. Being of Scottish heritage I could try Tartan but the clan one is not my first choice for a car interior. I find them comfortable and good for a 4 point harness.

Success. A practice go first, then drill 7mm hole, a small coating of flange sealant, then bend the tab slightly forward and fit the rivnut. It holds very solidly now.

Great work John

Thanks Rob. Unfortunately I have hit another snag. The alternator shaft is heating up very quickly on start up. I have a new fan with the double bearing so I suspect it's the bearing on the alternator. I'm going to have to think fast on this as there is a Porsche track festival in 3 weeks.

Update: I have ordered the two bearings in case I can't get a shop to rebuild the alternator in time I.e. I will do it myself.

If you can, double check the sizes of the bearings you have against those you've ordered. I ordered new bearings for mine whilst trying to eliminate a low speed whine only to find that one of the replacement bearings had a larger OD than the one it was replacing. (Can't remember if it was the nose or tail bearing)

I ordered the ones from the Pelican thread: AS-6303-2RS and AS-6201-2RS. They have the same dimensions as the writer posted. We will see. I have no time to pull the alternator now and Xmas in NZ makes it impossible to get things done. For a moment I wondered if the two pulleys were bound and the outer one was turning at the wrong speed, but I think I had the orientation right. At least the engine runs sweetly.

YaHoo!

Check the orientation of the spacer just inside the rearmost pulley. If put in the wrong direction it can heat things up quickly back there.
The proper direction is not exactly intuitive by the way- it can appear that it's facing the proper direction when in fact it is not. I did this some time ago and ended up toasting a belt while idling in my garage.
