Rivnut hell!

well today I have been replacing these evil inventions. They seize up and rip the body to pieces when you try and separate the parts. I should have done them earlier, but I didn't have time. In the engine bay they are all 6 mm fitted in 10 mm holes. Some are Rivnuts and some are Jacknuts. Over 50 percent have failed on my car. This time I have retapped the surviving ones and put some copper slip in there. The rest I am replacing with new aluminium ones. I then have to repair the engine surround which will require some fiberglass work. Not that time consuming but another one of the less desirable must do jobs.

I was lucky and got an original engine Undersheild. It was missing on my car, guess what it's held on by Rivnuts! 😡😡

Then it's onto the fun part, the engine! 😀😀

Oh, one more driveshaft left to do. The VW half moon washers come today somI can see if they fit.

Fabian, going by the pics of your mirrors, I might just have one, they came in a box of parts I purchased for an old project couple of years ago. PM me with full pics so I can compare.

Thanks John, have sent you a PM.

The T2 Vw capervhas a smaller radius driveshaft. I'm checking whether the VW Jetta driveshaft washers will,fit.

I have swapped some of the silicon pipes for rubber. Despite having matched the diameters I'm not convinced sone of the silicon pipes will seal properly because of the manufacturing tolerances of the original pipes. IMG_5884.thumb.JPG.25eab1597b80ef65b4586c1f92a8f1c5.JPG

They look the same, thanks. The only trouble is Ferrari prices! I now have the Audi boots which are £3.99 each. The trouble is sourcingbthe bolt spacers as the are slightly different in design. I may have found some but am just waiting for conformation. The VW cv joints on the T4 appear to be 108 mm, whereas all the older VW stuff is 100 mm. It's frustrating as the pole of unusable parts is increasing. I will find the solution eventually!

Was it a particularly difficult divorce, Fabian?

It's not happened yet, but Ive got a feeling if I mention ski racks that  might be the final Straw!

Superformance are the SJ Sportscars of the Ferrari world and prices are pretty good generally , for example timing belts : £8

The CV washers at £7.95 are not that brill though have to admit. Must be available somewhere cheaper.

I have started to think what is the purpose of these washers? Are they to apply equal pressure to the cv boot holder so it can't distort and let grease out? If so the new A3 design boot has reinforcement  built in so the washers would not be required. On some other VW forums they have been fitted without washers. 

Or are they used to help prevent the bolts from moving under vibration, so they don't wear a flat spot and undo? Judging by how difficult they were to remove ai dontbthink this is much of an issue!

With the new boots I have the original washers won't fit because of the reinforcement bulge in the Lip between bolt holes.  . Vw do a shaped washer but so far I can only find one for a 100 mm cv joint. Some T4 transporters use a 108 mm CV joint. The hunt continues. Anyone got a source for these?

Defo would not leave them off, they are made from a hard steel and spread the load of the bolt heads which are quite small. The boot holders are just thin mild steel.

Its interesting that on the Esprit with inboard brakes the CV joints are loaded both directions. This is quite unique. Normally the advice on driveshafts is they should always be fitted back on the car the same way they came off to avoid reversing the load but this happens all the time on these cars! Doesnt seem to cause any problem though.

thanks Andy, that's what I thought. There's a lot of rubbish on the internet!    

Well I think I may have a solution. I will confirm when the parts arrive. Just Kampers sell the T4 boot for the 108 mm CV joint. The T4 has a 100 mm or 108 mm cv joint, so be careful you order the correct one.  They may get the spacers in, but at the moment don't sell them individually. I mention if they did Lotus people might buy them! I believe the spacer is part 1K0407-357D available on eBay or VW directly. It's £13 for six. I have ordered them and will confirm if they fit.

Engine

Well I have started. The engine has been rebuilt before. The whole bottom end. All I have is receipts and no pictures. As the engine is already out I have decided to take it all to pieces and check all of it and rebuild anything that is required. Many parts are new but I don't know who did it. With a rebuild taking about 42 hrs it's small fry compared with all the other jobs so I have started to strip it. Quite easy as it's all been apart recently! IMG_5903.thumb.JPG.b1510387afcc67079af16bb3e7660746.JPGThere's a lot of dust built up. Everything I can getboff is going in the Ultra sonic cleaner after a parts bath. Shouldn't  take too long to do it all. Plus this job is fun! I want it pristine otherwise I won't be happy.👍🏻👍🏻

Hi Chris

Its a GT sonic 9 L. This is about the smallest you can sensibly get away with. Used with carburettor cleaning fluid or soap and water. It's really good! Supplied by Mr Bezos, via Amazon.IMG_5922.thumb.PNG.c21c4c33063f512ee787e013688679ee.PNG

With the carbs you can get all the parts from Eurocarb on eBay. They do a Dellorto rebuild kit and sell all of the parts so if screw heads  are damaged they can be replaced.

Graphogen grease forvthe rebuild eBay. 125 ml more than enough for the  job. 

Engine rotation clockwise when viewed from the front belt side of the engine. No 1 piston closest to the pulley wheels.

That and the manual with some specialist tools and you can rebuild the engine.

Glad the ultrasonic is getting lots of use Fab. Here's some simple solutions to use with different parts.

3:1 Ratio Pine Sol and water carbs/aluminium parts 30-60 minutes

1:3 Ratio Lemon juice to water for brass 30-45 minutes

1:4 Dawn dish soap to water for steel 45-60 minutes

I have half a dozen 1 pint plastic cups I put the solution in then put them into the water bath in the cleaner. That way you can do different metals at the same time.

Thanks Roo, excellent info! 

I like the cup idea. Someone on line was using freezer bags but I havn't tried it yet!

Alternator

my original is perfectly ok but looks tired. Has anyone sourced a replacement on eBay? If so can you please supply a link to save me the time if researching it. Thanks.
