45k wrecker rear winch worm shaft removal

[MAZ537]

Hello guys,

I am trying to remove the worm shaft , I have try to hit it with a 4.5kg hammer (wood block used between shaft) but no go...I have read both TMs and they suggest different ways to remove the worm shaft
Can anyone please share his own experience ?

Also can anyone suggest a good puller for the brake drum ? I have almost ruin the threads in my Unior one!

Thanks !!!

The second procedure is correct. The steel bearings get stuck in the aluminum bore due to dissimilar metal corrosion. It will take a lot of beating to get the worm out with both bearings stuck.
