Anyone install a 4 Speed or Manual Trans in their car recently?? if so, take a look!
 

I have seen a lot of people putting transmissions in lately in threads on here, so thought I would post.

I have never done this incorrectly, thank god but have seen it done incorrectly countless times - just the other day was buying some 68 Camaro parts from a guy we know, he built car from ground up, knows what he is doing, he had the transmission out, telling me about adjustment problems he was having with the clutch, just didnt 'feel' right, he had everything out on the floor...guess what, throwout bearing was on fork wrong.

It is a simple mistake and if you make it, the clutch will not work correctly.

good to know / thanks for taking the time & effort to post...... :thumbs:

No problem and if it causes a few people to say 'uh oh' I better pull my transmission back out before I drive the car...better than if they didnt know and let it be

I worked at a speed shop all through college, sooooo many people came in, putting a new clutch in, brought their bellhousing in etc, time after time bearings on forks wrong whether it was a 5.0 Mustang, Dodge Charger or Chevelle....

That was something that almost got me when I did the swap.

It just didn't "seem" right but it was. I read through the instructions several times and almost refused to believe it.

thanks for the refresher.

it is easy to mess it up.

:thumbs:

bump...for a tech tip reminder

I learned that one the hard way, too. Thanks for maybe saving someone alot of time and cursing :lol:

Hi BC,
What happens if it's in the wrong position ?
Does a person know immediately once the engine is started? Or is it more subtle?
Regards,

What it will do, it will squish the clutch basically, rather than throw it in, typically will get a stiff pedal, especially at higher RPMs and notchy shifting....it is not easy on the bearing itself of course and can lead to other heavier damage. as the bearing can not really pivot on the tabs when mounted incorrectly, the bearing will travel at an angle, rather than straight inward, so force can be exerted on mainshaft collar, binding as it moves rather than silky smooth

the inside collar of the throwout bearing, the tabs on the fork and the collar of the trans should have a very light coating of grease, have done it like that for years, have raced cars HEAVILY and never had any issues

I'll be doing this soon, so thank you for the pics.

I'm installing a new engine and will be having the Muncie freshened up a bit, it was suggested that I purchase a new clutch fork, is that really necessary?

I have not done one in years (current 71 is auto) Now I am wondering...must have been right never had a problem. :cheers:

Thanks will be doing mine next week

I would not get a new fork unless obviously bent..which in most cases, it would not be.

It doesn't hurt putting a new spring tab on the fork, if the parts are well worn..the tabs are cheap, Willcox etc should have them...

A lot of times, they can be set up incorrectly.....and for years, not knowing the damage it is causing, maybe the pedal just feels 'not right' on occasion etc, the issues at hand might not be in your face obvious, but then during the next tear down years later, you may find a collar gouged, oddly worn etc etc

Great info. Thank you as I will doing a swap soon and will use this a reference. Cheers

bearing
 

Boy I wish I was to that point but I will remember that when I do set the bearing. Very important info. BIG THANKS

another bump

Just did this job last year and almost made this exact mistake (thankfully I happened to be out bench racing with a pro-mechanic buddy)

So one more bump :)

Good to know, I need to replace mine now (72). Quick question, do you need to remove the bell housing to swap the throw out or simply remove the trans??
