wanted: throttle body from 164

[Paul]

I'm looking for the throttle body assy from a 3.0L 24V Alfa if anyone has one in decent condition to sell?

Regards
Paul

I think I have. I'll check.

[tipo158]

I might have one Paul. I'll look.

[Paul]

thanks guys - let me know if you come up with something. I had a bit of a snafu the other night and managed to damage the existing one - it can possibly be repaired but a replacement would be a whole lot easier. Yet another reminder not to work on the car late at night when tired....
(at least I can console myself that a) it's an easily detachable part and b) no hammers were involved)

[ChrisCar6]

Is this the one?

[strat24v]

that looks very much like an airflow meter to me??

[ChrisCar6]

Oh yeah,right errrmm.......I may have one of those too. I'll be back.
:mad:

[Paul]

I didn't know what that was, but knew it wasn't what I needed!!

Got a 12V - are they significantly different? - fly by wire rather than cable?

[Paul]

The 24 valve version is cable operated - here's a photo of the culprit I damaged:

9159

What happened (and I hate to admit it) is that I mangled the threads on the shaft with the lock-nut holding on the cable pulley when I was changing it out for a smaller pulley that I fabricated (to shorten throttle pedal travel distance). Initially, I thought I'd bring it to a machine shop to repair, but when I started dismantling it to remove the shaft, I had second thoughts about forcing it out of the bearings holding it on each side so decided to see if anyone had a complete unit instead. Worst case, I can probably revert back to the repair idea

[Darkspeed]

That looks very much like the 12V unit - I am just off out for the day but tomorrow I will get it out of the box and see if there are any numbers on it - I think these are also similar/The same as the 2.0L twin spark unit - but it has been a while since I played with those.

If you can add a couple more pictures, top and side plus any numbers I can compare with the one I have. As it owes me nothing that's all I want ;) Chances are the shaft is the same even if the castings have differences.

Had to go in the shed to get something and the body was right in front of me = It looks identical apart from maybe having a larger return spring.

Solex made in France - Part No 195320806200 will take take snaps later - gotta go.

Am I getting warmer?

[NoCorseChris]

The significant difference between 12v and 24v cable operated versions is that the 12v has a throttle switch, the 24v a pot. Unless you are using an OEM 12v ECU I'd guess you'd want a pot, not a switch. You can retro-fit a pot, but it's messy.

[strat24v]

think the 24v body is a bit bigger too iirc?

[Darkspeed]

12V one I have looks pretty much the same some differences being Solex and not Dellorto, same Bosch throttle pot - no switch to be seen - Size wise the bore at the spindle is 70mm. looks like Paul will be sorted with a 24V one so this can go back in the shed.

The one above looks to have a switch and the pot - no switch on mine.

[strat24v]

switch looks just like a pot and in the same place. If anybody needs a pot, I have a stock of used weber pf09's, 20 quid each plus post to club members.

[NoCorseChris]

Just remembered, some of the later cars had a pot. My 155 V6 had a later ECU than the 164 and of course there are other engines out there of the same vintage with a pot on a 12v.

In other words, I was talking bollocks! For some reason, had 164s stuck in my head, not V6 engines in general. Apologies.

If it clicks when you open the throttle, it's the switch type is probably the easiest way to tell quickly.

Chris - what I have looks similar to the photo you posted, but it is made by Weber and does have a pot. Now that I'd a bit of time at the weekend, I've been looking more closely at the damaged shaft and will try and rethread it today. It was M8, so I'll see if I can get an M7 thread on there. It's a bit tricky to center the die because the shaft is not circular - it has a flat on each side, but with a bit of care (unlike first time round when I damaged it), hopefully I can rescue it. Will update later

OK Paul.
This TB appears to have a switch that is activated by a cam on the quadrant of the throttle cable actuator thingy, and the 3- connector Bosch gizmo which I take to be a potentiometer attached to the spindle.

[Paul]

That's the same one all right - only difference is that I don't have the switch. I can see the mounting points for it, but it's not installed - must only be needed with some ECU's.

I did successfully rethread the shaft today, so looks like I'm back in business - thanks Chris and everyone else that helped. At least we've learned a little more about the different versions used.

I now have a smaller offset cam installed for the the throttle cable - the problem was my pedal travel was too much - the throttle pedal was actually higher than the brake pedal causing me to hit it sometimes when braking! Travel is now reduced to about 70% of before so pedal is now safely below level of brake

Just for info, a 164 24v throttle body doesn't bolt up to later 156/166 or gta plenum's, inner diameter and bolt centres are different. If you have a later plenum, you have to either fit the 164 version or make an adaptor.

Here's the type of adaptor John is talking about (on the right).

[turbonutter]

Pretty sure I still have one of those adaptors that I made for my GTA plenum to i think a 24V 164 throttle body - I think i still hav ethe throttle body as well if anybody wants one. I only changed it as i went DBW.

The adaptor is anodised black now...
