Now that the transmission was fully dismantled i began inspecting parts such as bearings, gears, syncro-hubs for any wear/damage looking for cracks, chips and scoring, calculating gear ratios by counting the teeth on each gear and then using the formula driven/driver=ratio and checking input/output shafts for their diameter using a micrometer. I recorded my findings in the work book. After that was done i began re-assembling the transmission following the manual.

Today i continued dis-assembling the toyota transaxle gearbox, the first thing i did was remove the gearbox cover using a soft faced hammer. Now i was able to remove the 3rd/4th selector forks and the reverse idle gear, with these gone i could pull out the input/output shafts for inspection and to count the teeth so i could work out the gear ratios. After that i then checked all the bearings for damage/noise.
(below shows the transmission with the cover removed)
(below are the input/output shafts).

Today we continued stripping down the Toyota gearbox. 5th gear from the input and output shaft had been removed for us due to problems we had last week (as seen in the picture below), so we started off by removing the 2 circlip rings attached to the input/output shaft using a pair of circlip pliers and a screwdriver, we did this so that when we remove the gearbox cover the 2 shafts with the gears on them would remain in the transmission housing.
We also got to see inside a manual RWD gearbox and how the power flow moves through it using a cluster shaft. It was good to see how this worked so that i could compare the differences between the FWD/RWD gearboxes.

Toyota transaxle disassembly
9/3/2011
Today we continued taking apart the transaxle gearbox, our next step is to remove the synchromesh hub on the end of the input shaft using a 3 legged tool which is designed to pull the hub off the shaft ,unfortunatly the hub was on so tight that is broke when trying to remove it as showen in the picture below.
