gday all I bought a really bad gtr it has sat in the weather for 30years the wheels have locked up .I cut the spokes and ditched the rims and put the hub in a tub for electrolysis its been bubbling away for around a week and the brake plate is still pretty firmly in place .does anyone else know of a trick to separate this cheers
-
Just had to do this very thing. I removed the bearing on the opposite side from the brake plate using my motion pro bearing extractor (basically this tool is a collet that is inserted in the bearing, a wedge ended rod is inserted in the collet from the other side and driven in to lock the collet in place. then the rod can be used to drive out the bearing.) Once the bearing is removed through whatever means, the collar supporter B and rear drum collar can be removed. I then used a large drift to drive on the collar supporter B and bearing still inside under the brake plate. This will destroy the collar supporter and bearing, but will let you save the brake plate. In my case the issue was the brake had gotten wet and the shoes were stuck to the drum. This is not pretty, but was the only solution after the various penetrants failed.

thanks bert
I was hoping for a less violent way of doing things but I think this is the only way cheers

After posting this, I realized that the last couple of posts I've made about work on my parts bike have been a little heavy handed. I really am a very sensitive guy...
;D
This was the only way for me as well...
Sounds like your new acquisition is in similar (very sad) condition as the bike I bought a few month ago, It had mouldered in a colapsed/defunct dealership in PA since the mid 70's. It is amazing, however, how many usable/restorable parts I have managed to salvage.
Good Luck...

yep the bike I bought is pretty sad and missing most of the motor .I paid as much for this bike as I would have paid for the right carb cover and luckily that's in excellent condition .Its almost laughable .when I dragged the bike off the trailer the front rim disintegrated when it hit the ground absolutely un saveable
-
I had to use my tractor's loader and a chain to lift mine off the trailer...would not roll at all (both wheels stuck)...
Glad you are finding treasures!

thanks Bert finding an original aussie import is very difficult . PROBLEM SOLVED after a week of electrolysis wich does not appear to have harmed the alloy I boiled on the bbq for about 6hrs (basically I forgot) then after all the water had got inside I put it in the freezer it had only one direction to go then Success !
-
Once again patience triumphs! Wish I had some. ;)
I had not considered that imports to Australia would be few and far between...
Congrats...

Wow, never would have thought of the water/freeze thing... gotta find a place in the ol' grey matter to store that tidbit! ;D
-
if I can get my camera thing working I will take a photo it looks like the hubs are full of sand its not pretty .with the oz imports I think there were 60
-
Coxy, Wow! That is FEW! My hub looked like it had sand in it too. I wonder if that is oxidation or some other decomposition of the stuff inside. I know the wheels were partially under water from the mark on the tires, but can't imagine sand could have gotten in...another BS mystery...
Moonpup, if are like me, room in the grey matter isn't the issue, it's accessing the info once stored. ;D

i think the sand type particles probably consist of aluminium oxide iron oxide and asbestos
-
Lovely! Now I wish I had been wearing a mask when I opened my stuck wheels up.
But I guess this should really come as no surprize since those materials are all that is inside.
