Need ideas for a clutch on a 91 TD motor

[8v-of-fury]

We just swapped in a TD to my bro's 84 jetta Coupe.



The clutch that came with the engine is slipping as soon as the boost realy hits in 3rd, 4th or 5th gear.

Obviously we're gonna need to do a clutch on this car, I want some suggestions on what to go with. I was thinking of upgrading to a 210mm clutch and jsut getting a stock clutch.. IDEAS PLEASE!

210mm FW
210mm 16V PP
200mm air cooled bug solid disc.
No hard pedal, no chatter, no problems with it in my truck.

  I just did the clutch on my td caddy.  Went with the 210 FW, 16v PP just like you, 210mm 8v disc for me though.   Interesting choice on the 200mm air cooled bug solid disc,  I didn't even know that fits.   What the benefit of the solid disc?  Better engagement?

Well the hub is nickel plated and seems to hold up better than the standard.
But yes, better engagement.
It was not like any of those on, off clutches that are solid hub types. Daily driving is perfectly fine.

the solid hub is stronger, and with a full circle clutch(not pucked) engagement wont be too bad.

the best part about the bug clutch discs is that they are really cheap(if you can get them shipped for reasonable prices)

I've got one with less that 5k miles on. I swaped to a 02J trans so don't need it. You can have it if you pay for shipping  .

so would a '91 TD come with a 200mm clutch factory?

I think maybe I will stay with the 200mm clutch so that I dont have to change out the flywheel and worry about the TDC marks

I mean the 200mm will have the clamping force needed for a mild 1.6TD.

solid disc seems good idea, same price really and a solid disc! why not. that with a new 200mm PP. what else do i need?

OOh PbS that sounds a good idea.. you have a solid BEETLE disc? what do you have? lol

The stock FW and PP is going to be 200 sence its a diesel and is a heavier FW. Maybe by '91 or '92 VW went to a 210mm. The other benifit of the 200mm disc is that if you use the 210mm FW and 210mm PP from a 16V is the better clamping force. I've never used a bug disc with the 200mm PP and FW. Try it and let us know.

I went with the sprung hub, not solid, 210mm 6 puck ceramic and I would NOT run a solid hub. I have to start rolling this like a tractor. Idle, let it out slow, engine slows enough to let it out all the way, then add go pedal. If you give it go pedal then let the clutch out it is violent. Pretty much on/off switch that twists the engine as much as the mounts will give. Hard to drive on hills with people that give you 2.54cm or 1" at a stop light without stalling or the violent launch.

my 91 eco motor has 200mm flywheel stock. I put a stock sachs PP and disk in.
Motor is turned up, K14, giles pump, fmic.
If I try hard I can make it slip.
I have a 210mm fw, pp and disc waiting to go in.

But if you are not planning any abuse a stock clutch is more than adequate and easier than sourcing parts and making new timing marks.

[theman53]

I did do 210mm *forgot to add that* and if you get one from the aaz the timing mark is the same

200mm units have the same spring clamping force as a 16v unit..

just less surface area to apply the force.

i like a 16v PP w/ an 8v clutch. sprung center..

havent had the need for a solid disk yet..

I just put a 210mm pressure plate/flywheel in an intercooled Rabbit 1.7GTD.
 It also got a wavetrac posi trany.
I chose the 210 because the stock 200mm was slipping @7psi and because I found an affordable used clutchnet 6-puk sprung disc that was for the more common gasser 210mm.

 I was worried it would chatter when starting out but it is really smooth.
 Went into second during a left turn and stepped on it, both wheels broke loose and the front went sideways.
 This disc is perfect; smooth start and great grab between gears.

I ran a sachs clutch, 200mm, in my 1.6td rabbit for 2 years of beating the snot out of it at hillclimbs...never had a problem at up to 20psi.

I had some slip before I put the sachs clutch in, but found that a rear main drip and input shaft seal drip were causing an oil soaked clutch.  Make sure you change both while the trans it out, it's easy and worth it...i've seen a couple of these cars come apart for a clutch, and they've had plenty of clutch left, just covered in oil.

[fatmobile]

Yeah, I didn't throw a new clutch in. Had a good looking used one around,.. the disc migtht have been slippery.
Got to agree, most clutches die because of a leaky trany seal.
 The mainshaft seal was leaking when I pulled the trany,.. but that doesn't get oil on the clutch as easily as a bad push rod tube seal.
 Might have been the reason it started to slip under high load.
 Mostly posted that last one as a review of the 6-puck clutchnet sprung disc. I was worried it would chatter on takeoff but is real smooth.
 The 210mm flywheel pressure plate I used had 2 pins, can't remember if that's 16V or 8V.
