Need help with 523 swap

[Turbo224]

Asking for a friend. He is installing an A523 in his 86 turbo z Daytona along with an 89 dual pivot k frame. What does he need to do? I believe he already has the shift linkage figured out. I know the bobble strut bracket needs to be moved. What else do we need to do?

[Dr. Johny Dodge]

if the 89 K frame is from a std trans car that will line up ok with the bobble bracket

in the interm , a piece of pipe stuck between the ears on the 86 K frame would allow you to bolt the bobble bracket against the side of the inner ear - I've done that with an 85 daytona / 555 trans and it worked out ok

need the newer clutch cable or swap the older clutch fork arm - the t-o bearing has some differences , slight so the fork swap might or might not work with what's on hand

shifter / cables
mod bolt hoile on trans mount

need large spline axles

[Turbo224]

So he has the large spline axles, clutch setup, to bearing, and all the correct shift cables. So the 89 k frame will bolt right in? What needs to be notched and where? That's the last question I think.

[Dr. Johny Dodge]

K frame should be a straight swap over

one of the bolt holes in the trans mount will need to be ground out to fit one of the bolt positions on the trans but it won't take much to fit

with the fork arm , they changed something about it's at rest position thus calling for a different length cable or the fork arm swap

He definitely needs a clutch cable to match the year of the 523, it is different. He will also need a 523/568 shifter, and depending on the year of the 523, he may need a clutch disk. A 90 will work with his clutch, a 91+ will not...

I've never swapped clutch cables on any 520-555 to 523 conversion. I do use the older non weighted arm but from what I've seen they're the same other than the weight on the end which slows my shifts. Trans, cables, and shifter are all I've ever used. I have always installed a new small spline clutch but that's because I'm going from stock to a puck clutch setup and an aluminum flywheel at the same time.

The drivers side trans mount bracket needs to be notched to clear the trans a bit, once you place it against the transmission you'll see the small amount in the corner that needs to go. I do it on a grinding wheel. Easy peasy. No hole needs to be ground out. The bolt pattern is the same, it's just the case of the trans is bigger in the corner.

I remove the grommets on each cable and run them through with the stock grommet as well.

Thought I took a pic and had it on Facebook

He has the correct clutch disc, 523 shifter and cables, and the trans mount grinding should be a piece of cake. 83 Scamp, are you certain he needs a whole new cable? The trans fork arm swap is simple enough if that bypasses the clutch cable swap. Are you guys saying that the 525 trans arm needs to be swapped onto the 523?

He was pretty certain that something also needed grinding on the trans case near the rear, but I have never heard that. Anyone have any idea about that? The only thing I can figure would need to be ground down is if he was trying to use one of the older larger style starters.

The difference that is being talked about on the release arm is the distance from the case when its all the way "down". Some are the same some are different depending on what plant the trans came out of or the year of it. Measure the 525 vs the 523 distance. It will be over an inch difference and if its the same on both trans use the stock cable. If its longer on the 523 re-clock the lever on it. You will need to grind on the blind spline on the release shaft for it to be re-clocked. Hope that makes sense....

[Turbo224]

Gotcha, I know exactly what you are referring to. I had this problem when I swapped a small spline 568 into my R/T.

[Turbo224]

Okay, experts. I helped install this trans last week into the Daytona and it appears we have the wrong lower flywheel cover. I assume the 523/568 uses a different lower shield, correct? Does can someone confirm? Picture below is the 525 shield that does not seem to fit, it hits the flywheel.Attachment 57155

Here are the shifter cables length.
