Shaft Installations

54.jpg (29924 bytes) Start by pressing on any bearings from the inner race only using a shop press.  Lube up the shafts and anything you can so it goes on easier.
55.jpg (31354 bytes) This was a shop press I welded up myself, 12ton.  MORE than enough for this tranny.  Behind that is a few trannies I am working on :) 
56.jpg (43530 bytes) These are my 2 new shafts, with 2 new bearings pressed on the sides that were not possible to remove bearings from the broken shafts.
57.jpg (42608 bytes) This is my parts layout for the intermediate shaft.  Go through the manual and you'll find its easy to do.
58.jpg (39637 bytes) Start pressing on the parts.  Make sure the synchros dont bind up and mate with their positions while pressing.  Also, these hubs go in ONE way only, so no possibility of mistaking this.  The manual is incorrect saying the 'punch side' of the hub goes toward the clutch housing.  On 99 trannies, they go the other way. 
59.jpg (30187 bytes) Check for clearances (before pressing of course) in these synchro locations.  .0020 is the minimum space you want to see (a worn synchro will show even less space).   Also run your fingers underneath the synchro teeth/rings.  They should feel sharp.
60.jpg (33332 bytes) Pressing on the final bearing on the intermediate shaft.  Do section by section, double checking the sliders go over the synchros and lock the respective gear without any binding. 
61.jpg (33190 bytes) This is a check they require for the circlip clearence.  They recommend .0002 or so, which is basically nothing, so its not very critical here.  Just make sure you cant fit a .0020 slider between the  clip and the bearing race.
62.jpg (28577 bytes) This gear is on the new input shaft they gave me.  Even new gears will have kinks like this so be aware.  I sanded this down a bit and hopefully it wont be a problem.
63.jpg (36231 bytes) Input shaft assembly.  Same ritual, press on the parts carefully and slowly, and keep making sure nothing binds.  (This homemade shop press does wonders eh? :)
64.jpg (36565 bytes) Another circlip check they require.  Again, make sure there is no space between this and the bearing.
65.jpg (36696 bytes) Final bearing pressed on.  I used 30mm impact socket, works just as good.
