Refitting OS driveshaft
 

I am finally getting some more done on re-assembly of my ZT-T.

Refilling gearbox today but hit a snag as oil is pouring out where the osf driveshaft goes into the diff/gearbox. I am guessing the shaft isn't far enough in, bit cannot find anywhere to apply force to push it further in.

I've released the bottom balljoint so I can apply some inward pressure - but can' seem to get the shaft in any further.

Anyone have any top tips?

Maybe the oil seal's damaged.

As T-Cut says it could be the seal. It's normal and quite easy to replace when doing any work in this area.

If you look directly at the shaft from underneath it will be clear how far it can slide into the gearbox.

Tapping the far end of the shaft should supply enough force to drive the shaft home without damaging anything. ( using a large soft headed mallet. )

Don't forget to make sure the circlip is correctly located
and has not become loose and that it's not the cause of the re-assembly problems.

I would think if the bottom ball joint is connected the drive shaft is right home. Perhaps you’ve damaged the seal when inserting the shaft, some new seals come with a protector you pull out after the shaft is installed as the splines can cut the seal

Thanks all. After coming in here to type out the post I went back outside and wrestled the shaft in a bit further - without hammering. Now just waiting to see if the leak has stopped before I carry on. It was about an eighth to a quarter of an inch (in the old money) from fully home.

Just been looking at that drive shaft in the Haynes manual.

Doesn't look like there's a gap there at all.

Someone on the forum must have actual hands on experience of this type of job. They just need to read this thread I guess.

Lets face it, nobody would be happy with a leaking shaft.--;)
