CRANKSHAFT ASSEMBLY
The drive gear in a hot oil pan (150°)
Slide the gear onto the crankshaft
The spacer in the right way please...
Distributor drive gear in the same bath at only 100°
Distributor drive gear onto the crankshaft
A few gentle taps around the fragile gear with an aluminium drift
Ready to install the hard and thick clip
Circlip attaching (need of a special clip plier)
The assembled crankshaft with his gears
The rods can be attached now
(as the crankshaft as been rectified we'll use +25mm bearing rods)
Unluckily, we did received a STD GLYCO rod bearing set from the well know Parisian aftermarket reseller parts. 😐
(GLYCO is a serious and well know manufacturer for years in that kind of stuff)
After a check we noticed that the main bearing set was wrong too,
we ordered 25mm Ext. / 25mm Int., (crankshaft has been retouch too) while we did received a 25mm Ext. OEM PORSCHE ones.😳
So we bring them back and exchange them without any problems with a week of a delay... Well, not a big deal, that can happen !😏
The exchanged GLYCO +25mm rod bearings set arrived and feet perfectly ! YES 😅
Sad to say that with the main bearing 25mm Ext. / 25mm Int. set, the story turn out in a nightmare, when we got the exchanged parts (we expect on GLYCO or OEM PORSCHE parts) a repack white boxes with a PORSCHE references sticker on it were provided ... 😢
OUPS, the reseller felt straight away the embarrassing feeling situation at the counter, very confident, the guys specifies that it is a German supplier to the PORSCHE standard.😚
Let's see the famous GERMAN supplier a bit closer.
We can clearly notice the offset of the half shell bearing
The hole is not facing the lubrication well
That concern the 12 half shells n°1 to n°6.😡😠😥
No comments needed to be done on that one
To avoid further loss of time we decided to :
The job done on the right halve
on the left halve
(this side do not have any well lubrication)
Test feet of the bearing shells... looks better
Lubrication holes has not been done yet
The red cross mark represents the holes to do
(facing the lubrication wells just behind the bearing shells)
Here we go !
OK that's done we can go back to where we were !!!
Notice the Carrera 3.2l new oil pump
New chains
New n°8 bearing +25mm ext.
The short block sealed
The famous all threaded 993 cylinder head studs
Boris adjusting precisly the height of the gudgeons at 133mm
The full set arrived
Each box contain:
Checking the ring gaps
Some rings needed to be rectified has they where a bit too tight
Cylinders 1,2,3 assembled
(installing the wrist clip can be tricky)
Right cylinders bench
Left cylinders bench
Well, we can move on to cylinder head work
Washing, microbead process, new valve guides, restored valves, recut valve seats, new valve springs were done.
As we recut the valves and the valve seats on the heads the height of the springs were reset and new valve stem seals were set up
Left bench
The oil return tubes waiting for the camshaft housing
Camshaft housing in place torqued at spec. then,
the cylinder heads were torqued at spec. 35Nm
A temporary mounting of the distributor was made... just like this
The rocker shafts on the intake valves n° 1 & 4 cylinders
Intake valve stroke in overlapping TDC with 0,1mm valve clearance, set at 0.47
range : 0,40 / 0,54
(as the crankshaft as been rectified we'll use +25mm bearing rods)

No comments needed to be done on that one
To avoid further loss of time we decided to :
- rework the block (which is not an easy job)
- return the shells
- re drill them on the opposite side in accordance with the oil lubrication pits facing the main bearings holes.
(this side do not have any well lubrication)
(facing the lubrication wells just behind the bearing shells)
Boris did that difficult and precise task in stride in a jiffy RESPECT MAN !!!
... GENUINE REGARDS & RESPECT...
👍 👍 👍
