Manual T56 Troubles
 
4 Attachment(s)
Hey Fella's!

Below are some pictures(not in order) that show my shift fork within a inch of hitting my floor, floor, and trans tunnel.

I forwarded these pictures to "the vendor" and was told that there is nothing they can do. In which they recommended going hydraulic. I was also told that my floor was the problem. Also mentioned was the product fits the car, the car doesn't except the product and the customer service are the only things they can do. Note: I have original floors in the car.


Any Advise???

Appears the tunnel clearance is more than I have, what motor mounts are you using?

Does the arm make contact at any point through the range of travel?

Can you clearance the floor without any negative impact?

Sbc 383, The arm has 1" of clearance until it hits. What do you mean by negative impact? We would need to rework the side of the tunnel.

It would be helpful to know your entire setup - car, current engine, transmission model and mounting used, engine stands, motor mounts, bellhousing and whether a factory clutch pivot or adjustable, and so on. It looks like a '69 Camaro, you said small block, and you're using an adapter plate.

The pictures doen't show a clutch pedal - how far into mockup and testing have you gotten?

69 Camaro, SBC 383, T56, Xfactor crossmember, Poly Motor & Trans mts, Factory Linkage, Adaptor plate.

Pedals are mounted using a Zbar.

Thanks again.

Man, this is like pulling teeth.

Have you installed the clutch, flywheel, Z bar, linkage, pedals, adjusted everything, fired the engine and determined that there's an issue - i.e., that you can't disengage the clutch and/or get a good clutch pedal release point with things as they are now?

It also looks like the transmission is clocked, as if you had an adapter plate intended for a third gen or have the transmission mounted in the wrong set of holes in the adpater.

Finally, have you checked driveline angles. There appears to be a LOT of room in your transmission tunnel.

Go hydraulic. :)

Negative as in footwell clearance for throttle function.

FWIW - Here's my '69 SBC w/ T-56 Mag.

W/ Moroso solid motor mounts.

I did a fair amount of massaging of the firewall to clearance the QT bellhousing.

Thanks for you help but I think we are on a different page.:thumbsup:

Is this a hydraulic setup. Thank you for your help. Appreciate the pictures..

Vegas69 08-08-2012 04:56 PM

This is a common problem when you use a clutch fork that is the HIGH STRENGTH version.(Something to that effect) A stock fork is the only one that works and will be plenty as I use it.

#2 If you changed the relationship of the throw out bearing by using an adapter, that could also be your problem.

It's manual with a McLeod adjustable throwout. I've been very satisfied with feel and modulation. My concern with hydraulic is the car may not get driven for 4-5 months during the Oregon winters and I've heard enough about leaking slaves associated with lack of use that I opted for old school.

As previously stated by Vegas69,the problem is your clutck fork. We have run into this problem many times over the years in lots of installs. The clutch fork you are looking for is GM part# 03892632. That is what we always use and have had success every time. Hope this information helps.

Appreciate your photos, they have been a great help.

Thank you for the part #.

And be sure to set up the clutch pivot properly, if it is adjustable. Measurement from block to pivot ball should be 4.75" according to my instructions. The measurement worked perfect for me.

Cole 10-17-2012 10:46 PM

Too funny.... I was talking with Vegas 69 the other day. He made the same mention and we have been looking into it the last couple days. I'll keep ya posted.

Thanks gentleman both you and Todd nailed. Josh @ JEP installed the longer pivot ball and it seems good to go.


Gracias
