Last week, it was pretty easy to use a cheap 3 legged puller, to remove the shaft, with bearings attached, from the body of my VP 2003 raw water pump.
Sadly, I didn't have the same success with this morning's little task, which was to remove those 2 bearings from the shaft (I want the spacer, from between the two bearings, to put on a new shaft).
I'd watched this excellent short video, several times:
See about 9 minutes in, if you're interested (and thanks to 'Sailing with US', if you're on the PBO forum.)
It convinced me that it looks fairly straightforward, even for one with my very limited mechanical engineering aptitude.
Hmmmmmmm ...... well ....... All was ok to start with, as the bearings moved steadily to the end of the shaft.
Once there, however, events took a turn for the worse, as the bearings refused to shift any futher.
I think the problem was that the 'drive shaft' of the puller wouldn't stay right in the centre of the pump shaft. I dismantled the puller several times to try get it lined up neatly, but all in vain.
So, in good, traditional, accountant, mode ....... I just went for brute force and ignorance, and wound the spanner with absolutely every ounce of my strength.
Eventually ...... oh dear (or words to that effect)......... there was a loud 'Crack!!', as the two bearing casings fractured.
So, I'm now left with the even trickier task of removing the remains of the bearing cases and the spacer.
I thought youtube would be packed with, 'how to use a 3 legged puller' vids, but I found nothing informative.
I agree, the theory is simple and obvious, but I found the real world application beyond me.
Any tips most gratefully accepted.
