We got a little bit more done on the Car yesterday, my dads back from Mexico so we started on it again.
Today was to fit the pistons & conrods into the block and connect to the crank.
Started off by measuring the conrod bolt length so we know if we ever take them out again if they have stretched too much over tolerance Etc.
Here is a photo of before we began.
Here is one of the pistons ready for fitting,
Next we turned the crank to bottom dead centre and put the piston ring compressor on and started sliding the piston and rod into place, lightly tapping the top of the piston to move it down the bore.
We got almost to the crank when it wouldn't move any further, after a bit of head scratching we realised the standard 2JZ oil squirters need slightly bending when you fit forged pistons as otherwise it fouls the piston on the bottom of the stroke, so we unbolted the oil squirter and bent it into correct position.
Once that was done the piston/rod moved all the way down and met the crank.
We plastiguaged the crank/conrod cap to make sure it was within Toyota measurements/tolerances and it was.
Once that was done we fitted the conrod cap along with acl bearing and torqued the cap upto 47ft/lbs as that's within the 45-50 range that's needed.
Now that was done that was one piston/rod fitted, here are 2 photos of one at bottom of it's stroke and the top of the stroke.
After doing this we decided to have a BBQ and some beers so the rest of the pistons will be fitted in the evenings this week!
Tomorrow the KW V3 coilovers will be turning up, meaning we can start fitting those too, thus-meaning we can finally get the car onto wheels rather than keeping it on the casters/dollys.
