The Case is Finally Splitteded!!!!

The past two Saturdays i've been working on the engine.... ....
.
.
The pistons come off by first removing the circlips... one on each side of the wrist pin...


Then put a socket on a long extention and slot it into and against the wrist pin.... then with a piece of wood i struck it to drive the pin out.... just enuff too remove the piston from the con rod..

After i removed all the pistons .... i noticed that one of pistons isnt the same as the rest.... hmmm it didnt have the same hump on the top.... (is that a bad thing) .... it didnt have the same arrow markings that point to the flywheel either.......





Ok.... well its decided then.... i will have to get new pistons......
.
.

Now to remove the pulley...... Slot a big screw driver thru the pulley holds and brace it on the case.... then removed the bolt....




Only after removing the pulley can screws securing the pulley cowl be accesed....



After removing the pistons and wrapping the con rods with lots of paper...... i was confident enuff to carry the engine and turn it over upsidedown... This is so that i can remove the Pressure Relief Valve and Control Valve.... having the engine upsidedown also helped me to get finally remove those pesky screws that are securing the side cowling....

The Oil pressure sensor was easy and simple to remove....

So was the Oil Pump cover plate........

Check the oil pump and cover plate for ware.... if its heavily wore out ..... just add it to your growing list of parts to buy.



To remove the whole oil pump assembly you will need a specialized tool.... Otherwise you will just need to split the case slightly before wiggling off the for studs.... for now just remove the the oil pump gears.....


I better put a photo (as shown below) of where the Oil Pressure Relief Valve and Control Valve are........


Ok .... now to unbolt and remove all the Crankcase nuts...... then strike the case with a piece of wood and mallot till it splits at the Flywheel side.... This is when you can wiggle the Oil pump assembly off the studs....
.
After that tilt the case on to the left side and wiggle the right side off.... if it still doesnt give.... un-tilt the engine and strike it again... tilt it and wiggle again.... for the love of money dont use a sharp object or place anything on the seams of the engine casing.... cos you will muck up your engine and you might as well trow it out and scrap it....



When you are taking the right side off .... four peices of errrrrr... #^&*(!!... i forgot the name lah... hmmm any if you see the photo below you can see 4 small round things will fall out.... so slowly do it so it does not fall out hard..... anyway i will update the correct name of those things later....
