Crosley?? T-400 Output Shaft 'O' Ring

When installing a MW driveshaft into my T-400 I come up about an inch long. I pulled the tail shaft extension and the "O" ring on the output shaft is stopping it from going in further. BTW, this is a MW 1350 billet yoke without any hole in the end to releive trapped air. I can feel the sponginess at the O ring and I can't get over it. I still have about two inches of travel available on the output shaft that would give me the room I need. I re-measured the shaft length requirements and the shaft and they are dead on.

With the air trapped in the yoke there's no way.
Thanks, Larry

Edit: Looking at this thing closer I found there is a plate at the end of the slip yoke held in place by an inside snap ring. I removed it and still cannot get the slip yoke over the O ring, lubed it, still won't go. I don't think the plug in the end will seal well enough to stop a leak and probably need the O ring for insurance. Any Ideas?

The O-ringed tailshafts take a yoke with a smooth bore in the O-ring end. Take the O-ring off the shaft and seal the u-joint end of the yoke. Shorten yoke. Or have the yoke counterbored enuf to slip over the O-ring

options list seems to be:

remove the O-ring. still not working?

Grind the O-ring groove edges down till the yoke slides over them.

Don't want to grind the output shaft? Shorten the yoke slightly. Full spline contact should still be there.

shaft on left in photo is early slip yoke shaft... shaft on right is later bolt on yoke shaft. Notice where the O ring is located.

Dont worry how old you are... it is the mileage on your body that adds up.
