MK2 Golf/Jetta and Audi 5k / Re: AC and PS v-belt configs

« Last post by oblique on May 05, 2026, 05:08:16 am »

thanks for the reply but its hard to visualize.

I found this on cabby-info.com..the later styles seem very similar to what the 1.6td looks like.

the full setup (including dual waterpump pulley w idler):


here we keep AC but remove PS...the compressor does not appear to change location and neither does the Alt...we just move Water Pump to single pulley.


removing AC but keeping PS the Alt DOES seem to shift downward slightly:


Its finding the required brackets and hardware that I want to know.

 There is a 1/2" belt that will go from the crank> waterpump> alternator.
In fact I think it's the same one as the stock AC setup.

 When I use the MK2 AC alternator bracket and alternator on the MK1 non-AC setup I rotate the alternator down as far as it will go.
 Then I see where it touches and grind some away, from both the bracket and alternator, so it will rotate even farther down.
 This keeps the belt shorter, makes it so you can reuse the stock belt.
 It also requires the ford double alternator pully.
 I swear someone on here has a picture of it as their avatar.

Oh and there is one more trick.
 The adjuster bar. I use 2 pieces.
 Rotating the alternator down, put the adjuster bolt hole on the far side of the alternator.
 I don't know how many old alternator adjuster brackets you have.
 I used a short MK2 gasser bracket, it has a hole near the end. I bolted it to the holes using a (head bolt?) washer as a spacer.
Basically move the adjuster hole to down underneath the alternator.
 Then I bolt a curved and slotted brace to the lower bracket hole.

I thought the info was in the FAQs but couldn't find it.
 Thought I would have a picture somewhere too but I'll have to take one.

MK2 Golf/Jetta and Audi 5k / AC and PS v-belt configs

Hey folks
Is anyone running AC with a manual rack? I want to convert my factory AC/PS 90 1.6TD Jetta to manual steering...just had an 86 Westy rack rebuilt but cannot find the v-belt diagrams. I could've sworn I've seen parts diagrams with all the different accessory combinations but cannot find anything...ideally I track down all the pulleys I need for a factory setup. Currently have the dual 'idler' style water pump pulley.

Also have a buddy who wants to ADD PS onto a non-AC 1.6TD 88 Jetta. Already have a good rack, pump, lines, etc. Also wants a clean setup. Whats the best route to go?

General / Internally Balanced Crankshaft?

« Last post by 1.6Lmarine on April 30, 2026, 04:53:52 am »

Good Morning,

Just a quick question today.

Is the crankshaft on a 1.6L TDI ME from a 1987 Jetta internally balanced?

Thanks so much!

Craig

I think the adjustment is good.  12-14 psi @ 4300 in second.  Shifts between the gears seems better as the turbo holds the spool up better now.  Not going to futz with it anymore.

30psi boost didn't make me go faster. I think due to back pressure.
 I actually have more power with around 15-20 psi with the 1.6D.

I had such trouble with previous heads that when I finally got the hydraulic head I wanted to cautiously approach the boost level.  Now that I am confident that the head will hold pressure I will tweak the level up.  Will I be doing 30 psi?

Likely NOT!

You will be wondering why you didn't do it sooner!!

OK,  If it doesn't rain too much on Sunday, I will pop the hood and torque on a couple of those adjustment thing-a-mah-jiggies. 

If I bump the boost up, I might not need to shift in the middle of the grade, doing that generally puts me in a no boost zone and in third.  Not great performance at that point.

Yep!! My 1.6 TD seen alot higher than that... My 79 would climb some steep hills around here.
