Wanted: 0.77 (tall) 5th gears


Sam Lin

Recommended Posts

Hi, I was referred here by Joe Paluch. I'm looking for one or two 0.77 ratio 5th gears (the tall ratio in the earlier cars) in good condition, and was wondering if any of you had them sitting around after you swapped to a shorter 5th gear?

 

Thanks

Sam

I am looking for a place as well, but I am closer to LAX (MANHATTAN BEACH)

 

Dylan still has the '88 tranny in his parts car and we need to get it taken out.....I need suggestions/help.

Jason, Dylan, Jim Marks:

Call me this week. I think I can swing it so that I can come get your trannies, bring them down to San Diego, swap the gears out, and return them. We'll talk pricing. Do you guys have the shorter gear pairs yet?

Best estimate is I have got 60 days left (with this freakin sore back) until I can drive/race this car.... I AM GOING CRAZY!!! How many more nights can I tighten/retighten bolts before I even get to drive it? I actually broke a Snap-On torque wrench retorqueing everythng I could get my hands on, out of sheer boredom! And to top it off, the Karting U.S. Nationals are this weekend, and I am a MECHANIC!! I tested all year for this event, to be on the sidelines... The racing GODS must be pissed at me......enough of the self pity.

 

Tim,

Let me know what I need to do. I haven't ever pulled a tranny, but I think I can figure it out!!!

It takes about 2 hrs to remove a tranny.That includes time to jack the car up. Unfortunalty I have not experience with swapping 5th gear.

 

PS... make SURE you use blue loctite on the CV joint bolts and use NEW bolts and make sure the threads are clean and free of grease.

 

I had some back out on me and it cost me a race simply because the threads had too much grease and the new loctited bolts backed out.

Joe, remember my ring gear failed at AMP? John Chambers had the tranny out in about 30 minutes. Now he's a Porsche mechanic/technician, but at the same time, it's not rocket science.

Thanks for the tips on the CV joints.

I remember one time on my green car, a CV came undone, spun up and bent the throttle linkage.......stuck it at full throttle! WOW!

I'm needing them to swap into 944 Turbo trannies, so my shorter 5th gears would then be available if that's what some of you are looking for.

 

Thanks, still looking

Sam,

 

I'm very interested in swapping my tall 5th with your short 5th. I'd like to minimize the down time in my car, so if we could coordinate the swap I'll go ahead and pull my tranny. I can be reached at 858-775-8739.

You won't get at the synchros, but if I recall correctly you will need the gasket on the rear housing and a rear "plug".

 

I had Pat at ITS Transmission do mine. He's the preferred tranny guy for german trannys.

My cars are currently together and will be until next summer, so I unfortunately won't be able to do a synchronized swap and minimize your downtime.

Sam,

I've got a 944 5th gear pair available right now. 27:37 teeth. I'm not absolutely sure they're a workable swap with the turbo tranny, that is shaft size, spline count, and depth.

Sam, You don't have any short pair to swap at all?

 

BTW, You will have to deal with the 5th gear slider sleeve and synchro. Once you punch out the rolled pin from the shifter fork, the fork, sleeve, synchro, and big gear stay as one unit (hopefully). The smaller gear of the pair is on the separate pinion shaft. There's 2 lock rings and a cir-clip to deal with. You must have a gear puller. We tried once to save the rear plug (for fun) and succeeded.

Neither it, nor the end cover gasket are expensive.

 

Jim Marks,

You might not have to replace the synchro for 5th gear. There are measurements to take once the synchro is pressed into the dog teeth( attached to the gear itself). You also need to do a visual inspection of the teeth themselves. No good putting junk back in there.

We're learning.........

Tim...

 

I am still waiting for your offer to come up, pull my tranny and replace the gears for me.......

 

I could trade you the most amazing brake cooling setup you have ever seen...... (I have been fabricating.....)

I was waiting for calls from Dylan and Jason.

We could come up to Hell A and pick up the trannys all at once. That was the plan. BUT, we need to have all three of you with short 5th gears in hand.
