Spigot bearing removal - what a swine!!
Fitted gearbox no. 3 today and decided to change the spigot bearing too. It was in super tight and and the pullers only broke it up - in the end we had to chisel it out.
Anyone ever work out a simple way to do these? Took us an hour of frustration!!!
Would be nice to know in case we ever have to do it again!

I usually get a clutch allignment tool, or a bit of bar that slides through spigot bearing.
Then first fill void behind spigot with grease,place tool just into spigot bearing and give a good sharp wack with a hammer.
The hydrolic force then pushes the bearing outwards bit by bit.
Just keep adding a bit more grease as it works its way out.
Never failed for me so far

Thats what we did Tab - the puller we had to hand just shredded it as it was in so tight. Plus the metal is so thin I guess. We've scored chisel lines on the inside of the crank in the process but that isn't an issue as the new bearing is held in well and nothing is deformed.
Next time go prepared with more chisels if needs be I guess?
We did also try the grease idea Andy, but it din't budge one tiny bit.
Maybe we were just unlucky this time around. That Burton Power one looks worth getting Manoj - thanks for the tip

ive done lots by using the hydaulic method.
pack the center of the bearing with a thick grease, its important you pack it completly and leave no air in there,
then find or make a tight punch which just fits in the center..i use an old school clutch alingning tool with various size ends...
put it in place and smack it with a hammer, 9 times out of 10, the bearing will pop out.
edit, someone else has said EXACTLY the same thing
must read first
