3 pin driver
 

Good evening folks,
I am nearing the point in my 1200 QL rebuild where I need a new 3 pin driver.
I have read several older post and it seems obvious that the stock driver is very flimsy. These things are selling for $120-$130 new and the used ones dont appear any better than mine. Before I bite the bullet & buy one, Is there anything I am missing that I can do or an alternative to make this any different? I think alot of you veteran members are very crafty when it comes to improvising.

thank you

Dave

Post up pics of the driver. Maybe I can figure an inexpensive repair

clutch driver
 

Lakota has nice aluminum 3 pin stock replacement clutch drivers for $55.00.

the 3 pin driver on a ql is designed to flex since its a rubber mounted engine, if you put solid mounts in you can run a standard non flex driver thats much stronger and cheaper.

I had considered going with solid mounts, but I've already got new rubber one's
I'll post a picture tomorrow

Thanks
Dave

Well.... then you better shell out the $130 for a new one.

It would be cheaper to buy a set of solid motor mounts off Jeff and a used regular 3pin driver. Your choice.

x2.... i converted my 1200 over to solid mounts, solid 3 pin. solid rag joint.

If you do go with a stock driver make sure you do the cradle mod to your engine mount brackets. The most likely reason yours broke is the ISO mounts failed and the engine sagged throwing the driveline out of alignment. If you do the cradle mod you will save your mounts and driver which will protect your investment.

Appreciate that info Bob, I did the engine mount mod, used the oil pan as a guide,
I'll go ahead and replace the driver with a new one and just hope for the Best.

thanks
Dave

I don't think you are hoping for the best. You fixed the problem.

The failed ISO mounts are probably the cause of the failed driver. If you did the cradle mod you killed two birds with one stone. You won't have a problem with ISO mounts or the driver again. Besides, the original driver lasted ~40 years before giving out. I think you will be fine for another 40+ years.

I hafta agree, if you keep the engine and drive shaft in line, the 3 pin driver will last a very long time.

Dan sent me pictures and I declined to attempt to fix it. The best I could do would be to weld a washer in to strengthen the flange but the metal has already been fatigued.

Texas Blues was talking about trying to fix his here;

Maybe he will chime in or you can PM him and see if he had any luck doing so.
