Thanks for posting the pics.
Thanks for posting the pics.
Coz asked me to answer your question concerning the Make-Up of these Bearings. This material, 'OILITE' is a 'Sintered' Bronze. Meaning that it starts as a powder and is compressed under 1000's of Tons of pressure until it remains whole. OIL is trapped with-in the pores of this concoction, the Oil can be 10% to 35% of the Total volume. In fact when I Machine them on the Lathe, Oil runs out constantly. And the dripping out of the Oil is exactly why Oilite is perfect as a Pilot Bearing. The Metals used for this Bearing, can be any of the following %'s. 84-90% Copper, 4-9.5% Zinc, 0-8% Lead, 4.0% Tin. We have proved in our 'Testing to Destruction' that it is Impossible for a Bronze Bearing of any kind to Harm in any way, the Input shaft of the ZF Transaxle! The Bearing, Itself will simply Desintigrate, at the point of contact; First! Also, I have had the Imput Shaft discribed, by Unknowlegable Persons; as being 'Semi-Soft'. This My Friends is plan BS! The Fact is, the ZF Shaft is 'Gear Hardened'! And when a Machinist Tests it for Hardness, with the Most commonly used Tool in the Machine Shop; A Hand File, the file just glances off with-out leaving a scratch! NO Bronze, least of all Oilite, will ever do damage to your Transaxle! Now, the Original 'Steel' Roller Bearing is an entirely different story!! All the best!
Not to mention the original bearing cannot be serviced (greased) without removing the gearbox.
Whereas this bushing does not need servicing.
Thanks Marlin.
