Nonexistent clutch slave cylinder bracket and release arm 4 Speed Muncie (Page 1/3)
lyleap-gmc AUG 14, 10:57 AM
Hi,
I'm still stymied by the nonexistent Clutch slave cylinder bracket and the throw out arm. This is for an 1984 Muncie 4 speed with a four cylinder engine.

What are the alternatives to these parts or am I going to have to start the engine with the clutch engaged and the transmission in gear. How long until the starter or its mount breaks?

Is there a hydraulic throw out bearing that could be used? That would eliminate the search for hardware that is nonexistent.

Were there other cars that used this bracket and throw out arm? I know that is a tough question.

I could swap the transmission to something that the parts are available for. That would be lots of work and some considerable amount of money. For me, any amount of money is considerable. PullRParts transmissions are reasonably priced but the work space is very lacking! Dropping a cradle in a sand lot isn't my idea of fun let alone even an accomplishment.

I'm stuck with an unusable car until I get some solution to this issue.






Thanks for all your input,

Lyle

If you're low on money/resources, talking about swapping transmissions and retroffiting an HTOB are the most bass ackwards ways to go about getting your Fiero fully functional.

You do modifications like that when you do a bling-bling megabuck build and are planning a lot of downtime for the car.

Seriously, just find stock (or equivalent) parts. They built 136k 84 Fieros, so there are a bunch out there. Also there is some interchangeability with the 85-86 4-speed transmissions.

Just find a u-pull-it junkyard with a 84 Fiero (85-86 is worth looking at too), and take what you need.

You can even drive your Fiero to the junkyard. It's not unuseable... it's just a bit less luxurious. From my (at the time) home in Valcartier, QC, I drove my Fiero with no real clutch release functionality to:
1. Saguenay, QC
2. Montréal, QC
3. Plattsburgh, NY - I crossed the international border. In this instance my clutch master was sitting on a shelf at home, absent from the car.
You can check how far I went using google maps.

If you have to drive 6 hours to find the right u-pull, well, maybe that's what needs to be done if you want to keep this car.

Staying stock is pretty much always going to be the most economical and expedient manner of getting your car fully roadworthy again.

Rodney Dickman's slave bracket might work on an 84:

Ask him what he thinks about fitment on an 84. Doesn't mean the bracket won't fit; maybe he just didn't test it on an 84 and cannot guarantee fitment.

Post in the Mall section asking for Cast Iron clutch arm and slave cylinder bracket for Muncie 4-speed.
Someone may have a parts car with what you need.

I don't recall the 84 slave bracket looking like that. I know the one you show is for the 4-speed V6 applications.

That is very likely correct. I needed some sort of image to show what I was looking for. The '84 used a Muncie four speed. Later years used Isuzu or Getrag even behind the four cylinder.

Good point. Here's the slave mounted on an '84.

No, the Getrag 5-spd was only ever used with the late '86-'88 V6. (From '85 to early '86, a 4-spd Muncie was used with the V6.) All '85-'88 L4 Fieros used a 5-spd Isuzu.

It may still be possible to bolt the V6 stuff onto the 84 case, but I am not sure.

About 3 years ago when I was building a FrankenMuncie, I don't remember there being major differences between the cases (other than the obvious ribbing). However, my memory of that is fading away.

I didn't keep a smooth case in my (too large) parts stockpile.

Does anyone have a picture of the 1984 clutch slave bracket? I am confusing everyone and I am getting confused as well.

In looking again at the transmission I see no bolts or bolt holes other than the transmission to engine bolts. Is that where the slave bracket mounts?

Please help me understand.

The original '84 slave bracket is in that picture I posted above.

However, I believe it was a rather poor design, prone to cracking. As has already been mentioned, you might be better off going to a later style slave and bracket.

Contact Rodney Dickman and ask his advice.
