Couple sets of AAZ injector hard lines in the parts score. One set really rusty and did some chemistry test on them first.




UGLY


Did use the ultrasonic cleaner


Heated and did make some black phosphate on surface. But no rust anymore.

I'm going to keep the notched crank timing pulley as is. Not going to have any substantial weight on crank snout and also only going to have one V-belt to drive. I DO have a New 6 point longer 10.9 grade bolt ordered.

Crank bolt differences


A Few parts cleaned up.

Good. I think you can broaden your search to include AHU parts.
 Which are often easier to find.

I Think I am OK with everything for now. Lotta SHTuff picked up from Rabbit Jockey and new pistons should be here in a couple days.

I think you should use the later TDI crank sprocket.
With the flat spot.
 Those crank sprockets were a known failure point for the AAZ and 1.6D.
You'd have to make a flat spot on the crank but I can send you my special tool for doing that.

  The AHU came with a serpentine belt setup. I'm not sure how it works with a non-AC setup.
Otherwise I would use the MK2 alternator setup because the alternator is a 90 amp one.

The weekend is over so I'm going to start pulling the 1.9 apart and swapping it over to the 1.6.
I'll start a thread on the topic take some videos and pictures.

Also need to get the rest of the garden in.

Mocking up parts to block to get an idea of whats Not going to work

No harmonic balance damper pulley. I have a V belt damper from 1.6 TD but pass. The 1.6 I'm running now I did not use one either.
VW logo INA T-belt tensioner pulley found in the hoard. Think the WP pulley is NOS too, 068***K I believe is the number on it.


No non AC alternator bracket to mock alternator but have crank and WP pulley alignment sorted. Hard to get the cast iron ones anymore. May need to just use the one on car currently that I fitted a 90A alternator on.
Think the 30mm WP is Graf, says Hecho in Germany on it... seriously, it does. Metal rubber later gasket to housing and stainless bolts.


Dug up a really nice set of 1.6 TD injector lines. And as predicted, they don't fit. But if one needs to mod earlier lines, these would be it because they have places where some length could be made. More squiggly's or service loop length than NA 1.6 lines.



Ordered a few N90577101 crank bolts (47mm), 12 point  with the Nub on end. About $3ea from AutohausAZ, Only to realize they used the older 1.6 TD crank bolt previously and it is 56mm long. Head is hammered from impacting, on/off a few times in it's life. But I think I am going to use the Earlier bolt again, saw a new one on ebay for $15. The couple I have in the stash are just as hammered as this one. This one also took the Big Boy M18 Milwaukee to get it off.
Even with the early HD bolt and being stoopid tight, I can still see signs of movement. Also looks like the mating surface on crank gear is Not flat. MIM or metal injection molding flaws, mold flaws, just wear? I dunno.


Found this 068105263C crank gear in the hoard. It is identical in every measure to the 028105263 I took off. Got it... Use It.


Did some deep digging and I came up with a new set of pistons, here in USA! Correct 24mm pins. NPR Europe brand. I have used the brand before and Shouldn't be made in China. Beat PPI price by around $100 to my doorstep.

You going to put a turbo on it?
Absolutely.
I was prepping TD exh manifold and a 171 TD down pipe last night.

 I think the pully looked good on the 1.9 I'm taking apart. I'll check.

Your alternator is different than the ones I work with.
 Kind of looks like it's for a non-AC MK2.
 That lower bolt hole is right there where an adjuster backet can get to it.
Usually those 2 holes are way on the other side of the alternator.
 So now you just need a curved bracket with a hole in one end, to mount to the lower alternator bracket hole.
 And a long slot in that bracket to slide the alternator bolt on.

 And if you can grind on the alternator and bracket a little near the top where it's touching,
you can bring the alternator down far enough to use the old AC belt.
Shorter the belt the better I think.

 Seems like I sometimes have a problem with that top alternator pivot bolt trying to come loose.
 So I use a longer bolt and put a nut on it too. Double-nut it.

 And I'm thinking belt 2 goes around the crank, waterpump and power steering.
 There should be another pully on the waterpump maybe.

Doesn't look like the double-pully ford pully on the alternator so it might not line up with the crank and waterpump pullys.
