For my reference as much as anyone elses, this guide should walk you through removing a Hillman motor, and renewing main/big-end crank bearings, pistons / rings etc.
Removing the engine :
I prefer to remove the head while the engine is still in the car, nothing tricky about Hillman motors :
remove battery
drain & remove radiator
undo interior heater pipes from the engine.
no need to remove the inlet/exhaust mainfolds from the head :
- undo fuel pipe from carb, remove cable bracket from manifold, remove carb from manifold (no need to remove throttle / choke cables)
- remove exhaust pipe at manifold joint.
remove rocker cover
** undo oil feed pipe feeding into bottom of brass casting in the middle of the rocker shaft
remove rocker shaft and pushrods
- rocker shaft is in 2 sections with a central brass oil-feed casting. Be careful not to drop any bits.
- keep pushrods in order - use cardboard with 8 holes punched in to stop them getting mixed up
remove small bolts along the top of the timing chest cover (the ones that go into the head)
remove the head.
If stripping the motor for a rebuild, you can also remove :
oil filter, and oil filter housing (have rags ready to catch the spilt oil)
distributor. take a photo showing order of plug leads or cut notches 1,2,3,4 into the plug caps for identification later. undo 2 bolts holding distributor clamp plate to the block, remove distributor (no need to undo the bolt clamping the plate to the distributor).
alternator
waterpump (4 big bolts holding the housing to the block - no need to undo the smaller bolts holding the pump to the housing)
no need to remove the bonnet - open bonnet fully until it hits the stops - find a long pole to hold it in this position.
undo engine bellhousing bolts - use an engine crane to take the weight of the engine - undo engine mounts - slide engine forwards slightly to free clutch - lift engine up & out.
Tips :
a cheap magneting tray is ideal for keeping all nuts & bolts together.
