Hello again ,
After several months without no news , started again a new engine rebuild .
For this new project i needed :
1 engine donor from tdm 900 5ps
1 gearbox from tdm 850 4tx
1 engine from tdm 850 3vd
so after several months i got my hands on a tdm 900 engine 5ps for parts , found a gearbox from tdm 850 4tx , and regarding the 3vd engine already had several engines at home .
First part of the project was disassemble the 900 engine to see parts i could use on the project .Apart of the cylinder bloc plus the pistons , manage to use water pump , both oils pumps , oil sump ( its deeper than a 850 sump ) so more oil available in the sump , both connecting rods since they have a larger piston pins.
Since the TDM 900 cylinder bloc is bigger than the 850 i had to machine the upper crankcase to match the new cylinder bloc.
So the first step was to machine the upper crankcase
