The rack housing and rack gear cleaned up and painted.
There is a needle bearing at the bottom of the pinion gear housing. The four semi-circles are where the pinion cover was staked to prevent it from coming un-done. The rack was clamped in the mill and each of the staked areas were cut away with an end mill to prevent damage to the retainer cover threads. If this cover is simply wrenched off, the threads on this cover will suffer some damage.
The back side of the pinion gear housing. It is made of a nice aluminum casting. Date code appears to be last quarter of 1979.
A threaded rod, nut, washer and bushing collar is to press the bronze bushing into the rack gear housing tube.
Apply pressure by wrenching the nut on the end of the threaded rod. Precision is required here to align the roll pin holes with the rack housing tube slots.
Once the bushing has been pressed to the correct depth and roll pins aligned with the tube slots, 0.125 dia x 0.25" long roll pins are installed into all three slots. There will be a 0.006' to 0.008" gap between the end of the roll pin and rack gear once the roll pins have been pressed flush with the rack tube.
A hole is drilled for clearance #6-32 button head socket head screw with self locking nut. To make sure that bushing will not come out..
These are the pinion gear parts. The bearing is a #6202. There is a rack tensioner assembly with spring, O-rings, plastic shims, cover and two M6 bolts.
Close up of the pinion gear, bearing, cover and related parts. The pinion gear was copper plated before heat treatment and finished ground to size post heat treatment.The rack gear has been induction heat treated. There is virtually no wear on this pinion gear and rack. The #6202 bearing was replaced, but not really needed as all the parts were in very good condition. This is a quality steering rack in every way for what it cost. It is technical details like this that folks who claim FIATs are cheap heaps never see or understand... This is just a small part of what makes these cars such a value for what they cost.
Pinion gear with #6202 bearing and external retaining ring installed. The rack gear gets lots of Redline synthetic CV-2 grease on the rack gear, pinion gear and bearings.
Pinion gear ready to install.
Next update will be installing the ball joint ends, rack boots and etc.
