i am replacing a leaky water pump, and cleaning up a bit of the engine parts on my 230 sl 1964 model year, i want to remove the housing that bolts to the block, question is how do i remove the housing, i have undone 2 bolts that hold it on, but there seems to be a bolt (it has no hex head) that is snug upto the harmonic balancer, does the balancer have to come off? is there any exploded diagram of the 230 engine online anywhere?
thanx
