Not sure beer cans are made from shim stock, but whatever works for you

Hi, the front end has been pulled down again in readiness for the next round in the gear saga. My mate at work has turned up a pair of adapters that each have a suitably sized stud welded into them at one end to suit the threads in the crank gear and an internal threaded hole in the other to suit my puller. I intend to attempt the removal using a 10 ton bearing puller I have, I am just waiting for a replacement ram to arrive. I am hoping that 10 tons will be sufficient to remove the gear... I have used this tool to remove some very tight gears inside Ford Galaxy gearboxes in the past. The gear in question was such a tight fit that it needed neither splines nor keys to hold it in position and stop it slipping. Of course, now it is going to be used on the Mutt I bet it'll struggle like mad.

Dan.

Here are the adapters that my mate has made that will allow me to use my hydraulic puller to remove the gear.





They fit perfectly and should hopefully work well although I am still waiting for my replacement hydraulic ram to arrive before I can actually attempt the pull.



Knowing this engine it'll probable fail in some way so I have a rather drastic "Plan B" which will involve cutting the gear down to the key with a reciprocating saw as far back as possible then splitting it with a cold chisel.
I am hoping that it will not come to that..................................... But this being the Mutt probably will.

Good luck! Certainly looks a sturdy job.

Might be worth your while knocking up a cap for the end of the crank for the puller to bear down on, just gives you a second chance should it slip off centre.

Phill.

Good point mate, fortunately my puller kit has one of those that fits over the nose of the ram and has a point on it that will engage with the centre in the end of the crank.

I now have the replacement ram and all being well I will get hold of a decent blow lamp tonight. One thing that is worrying me a bit is possibly damaging the front main bearing behind the gear. It is lined with white metal and I really do not want to melt it!
What sort of temps would be needed to damage the bearing or will heating the gear up not be enough to cause damage?

White metals melt at about 240C whereas soft solder melts at about 190C, so in other words, not a lot hotter than solder - you will need to be careful!

You'd be better with oxy/acetylene and a gas welding torch, far more concentrated heat than a blow torch.
