Choose a block suitable in shape and size from the table
below. Position the cylinder head centrally on the block
as shown.
1 Position the block and cylinder head assembly
underneath the press.
2 Gradually press the retainer upper surface until the
bushing falls out from the cylinder head.
Note: Normally it falls out with a load of less than 3
tonnes.
The press ram stroke varies with the cylinder head size
and is about 32~52 mm.
1 Use a retainer when pressing.
2 If the shaft centre of the block and cylinder head
assembly become misaligned, stop the press work
and realign before proceeding.
