Transmission Rebuild

Need some advice here......I started tearing down my transmission the other nite and cant seem to get the front part of the mainshaft out. It is hanging on the oil slinger. I have been inside a T90 before and have never had this problem; although most of the oil slingers I have seen come out of one are nicked, stratched up, and bent somewhat. This one is not. The mainshaft will clear the cluster gear going out the front fine but will not clear the oil slinger (the last set of teeth are hanging up by about the width of the teeth) Anyone have this problem before?.....prying and bending it down is an extreme last resort. Any help/advice would be appreciated.

Thanks

Look over this rebuild guide...

I used it and it was great... If I remember the oil slinger will come out after a couple of scrreews are removed...

Only been in my T-90 once, so far...

Hope this helps...

Thanks for the reply Hal. Screws are removed. When I couldnt get it to slip out I went to the rebuild guide to check. It should come out. I am wondering if the Trans. has been rebuilt before and the slinger was replaced with one that was not quite up to original spec. Is this possible?

Finally got it out last nite. I ended up removing the snap ring on the bering on the frnt shaft, put a couple of wood faced clamps on the front bering to hold it in the case and tapped the mainshaft out the back instead of the front. Since the needle berings on the top input shaft had fallen to the bottom of the case I am wondering if one was below the cluster gear preventing the oil slinger from sliding down far enough to clear the input shaft. Anyway........finally got everything out with no damage.

Simplistically if one removes the countershaft (replacing with dowel)...this will allow the cluster to lower in the box and then the transmission input shaft (and all other bits) can be easily removed, without all these hastles
Same on re-assembly put the cluster in the bottom of the box with a wooden dowel the same length as the gear (holding needles and shims) in place of the countershaft. Once everything else is together turn the box upside down then seal and install the real countershaft which replaces the wooden dowel pushing it out.
