Just poring thru TBe4 manual... something interesting.
New spareparts! (suitable for EvoIII?)
51109 TBe4 ONE WAY GEAR SET gives 2x Oneway Ring Gear, 2x Bevel Pinion gear
51110 TBe4 BALL DIFF GEAR SET gives 2x ball diff Ring Gear, 2x Bevel Pinion gear
Lotsa spare bevel pinions
Chassis is new, mounting points for new gearbox is different so these parts cannot be retrofitted to TBe3.
51090 TBe4 950 Ball Bearing 4pcs
