All in - pulling the 4.6 engine and trans to fix oil leaks once and for all

Phil, would you mind sharing the I.D. and O.D. of each of the 3 spring compressors shown as well as the height of the welded on "U"?

Thanks!

I wonder if something like this would work?

The D brake piston, in particular, is quite narrow so I would imagine you’d need the ‘custom made’ spring compressor tool at least for that one.



The three sizes I use are :

Large (D brake) = 164mm o/d, 155mm i/d
Medium (B clutch & E brake) = 110mm o/d, 97mm i/d
Small (A & C clutches and F brake) = 89mm o/d, 80mm i/d

These are the diameters where the tool actually contacts the spring but you may wish to add a step in the ‘hoop’ to bring it up to a large enough diameter to weld the ‘handles’ to.



Each tool is around 125mm tall (total height top to bottom) to suit my mandrel press.

Thanks for the size details Phil! Didn't think about the narrowness needed. I'll probably see about fabbing up something like what you have.

Deal on the 20 ton press fell through. Some guy picked it up this morning. Wish the seller would have at least called me instead of making me drive an hour to his place... Oh well, back to looking for one of those again now.
