Removing Tappered Pin from Right Axel
« on: May 14, 2018, 18:36:25 »
Do I need to remove this pin from the flex axel in order to get in and change the oil seal. According to the manual it's a tapper pin that is drawn tight with a nut and washer, if that is the case then the nut and treaded end of pin is long gone.

Thanks for the link. I have been hitting it with a large hammer but guess I need a bigger hammer. It was evident that someone had worked on the tapper bolt since the threaded end had been sheared off. I would just hate to remove the pinion just to get the right axel out.

I'm a bit unclear about what you're trying to do. The pin should drive out from the end that had the nut on it and the shaft has a milled area for the pin to slide through which also locates the shaft. If someone tried to draw it through without having the shaft centered for the pin to slide through it could be why it's stuck and why they broke the pin off.

After looking at your picture with arrow I took the liberty to modify it to point to the tapered pin.

That makes a lot more sense Hans. I guess what was pointed to prior were blind holes for casting purposes/alignment purposes?

Precisely. Blind holes used for fixating the item when seats for bearings etc. were machined

Move the swing axel up then drive the pin out with a drift. I leave a nut threaded to the end and flush on the pin so the threads have less a chance of being damaged.

Thank you for showing where it is located. My manual led me to believe that the hole that I was looking at was the spot. You have saved me a lot of wasted time.

What Joe says about protecting the threads is important.  The tapere pin sells for over $100 these days.
