Mazzo’s 1159cc Engine rebuild (Part one)
I managed to collect the block back from Cylinder Rebores at Lunchtime today, they have fitted the cam bearings I provided and washed the block very clean. So let the rebuild begin. It looks scruffy on the outside, that doesn’t matter, as I will repaint it once its all back together.
So down to the block, this is how it looked once back into the shed of plenty:
I re-fitted the tappets back into their respective holes, making sue each one was well lubricated and slid nicely in the block both up and down but also rotational. I then fitted the camshaft back into the block after lubricating the bearings and journals.
Next were the Main bearing shells, each was cleaned and dried, then fitted.
Changing the block position on my rotary plate enables me to fit pistons and quickly twist the engine around to check the fitment. Starting with number one piston. The pistons have done about 1000 miles and just needed a quick wash. They look dirty but its just burn on the tops, the actual pistons are whistle clean
So we are almost read now to drop the Crankshaft into the block, but first we need to fit a new rear crank oil seal and make sure its sat correctly.
Next we lubricate the main and big end bearings shells in readiness of lowering the crankshaft into the block. The lubricant I am using is engine build graphite paste, (I started using this about a year ago and find i get a better build than using STP) which is messy as anything and one has to keep cleaning everything again and again.
Then I lubricate the journals on the crank before fitting the Caps to the main and Big ends.
Now the Main caps
Then the big ends
Thats where I finished this afternoon, I still need to fit the timing gear and oil pump, before I close up the sump, the head I am leaving as I found it. The rest will tackle nearer the day I refit it to the car. Soon I think?
