\n

The bug was rear ended last year, and the motor\/transmission combo was pushed forward, shearing the rear transmission mounts off (they are rubber) and severely squishing the front mount. I cut out the old front mount and welding in a replacement; thank goodness they are easily available from online sources, otherwise I\u2019d be fabricating one.\u00a0<\/p>\n

I\u2019m documenting my transmission work on video, but I\u2019ve come across a question. I\u2019m attempting to rebuild an older transmission that pops out of fourth gear. I had bought it on eBay a few years back when having some problems with my leaking main transmission (which I later solved). The transmission that was in the wreck has severely damaged ring and pinion gears (probably from the wreck), and some other problems that were under way before the accident. However, it was rebuilt within a year or two, and has good gears and synchros, so I want to re-use them in the one that pops out of fourth.<\/p>\n

Transmission \u201cA\u201d pops out of fourth.\u00a0<\/strong><\/p>\n

Here\u2019s the main drive shaft:<\/p>\n

\u00a0<\/p>\n

The top gear is fourth gear, and it is missing some teeth. But it appears as though they were explicitly ground down. Is that normal? Or did they break off? I did find one tooth in the transmission case; so it came from here, or one of the other gears.<\/p>\n

Here\u2019s another angle:<\/p>\n

\"IMG<\/p>\n

\u00a0<\/p>\n

If I pull fourth off, the missing teeth are obvious and \u00a0look at the flat surface on the right; it looks like it was welded and then re-ground flat. Strange\u2026and the other transmission doesn\u2019t have this done to it. I\u2019ve heard about people welding the gears; maybe this is what is meant\u2026but it doesn\u2019t make sense. I think they mean welding gears to the shaft, not this way.<\/p>\n

\u00a0\"IMG<\/p>\n

\u00a0<\/p>\n

\u00a0Third gear also has missing teeth that also look explicitly ground flat:<\/p>\n

\u00a0<\/p>\n

The synchros (the gold colored things) don\u2019t seem too worn. So, I\u2019m surprised this thing pops out of fourth, but maybe it is simply because of the missing teeth on the gears:<\/p>\n

\"IMG<\/p>\n

\u00a0<\/p>\n

Here\u2019s the pinion gear from \u201ctransmission A\u201d:<\/p>\n

\u00a0<\/p>\n

\u00a0<\/p>\n

From left to right (right after the slotted retaining sleeve \u2014 note that the slot is also strange, is that normal?) \u2014 the gear between the first and second gear is also missing teeth; it is hard to see it in the photo. These don\u2019t look ground down, and may be where the broken tooth came from. I need to re-use this pinion gear (and it\u2019s matching ring gear, as they are paired), and push off all these other gears and replace them from \u201cB\u201d (below).<\/p>\n

\u00a0<\/p>\n

——————————————————————-<\/p>\n

Transmission \u201cB\u201d<\/strong> was damaged in the wreck, but has good gears\/synchros because it was rebuilt by Mofoco transmissions a few years ago. But\u2026I had trouble with it from the start; it burned out *after 20 miles* destroying the pinion gear and they questioned me putting oil in it (I did, of course). I think something was still up with the transmission (more on this later below).<\/p>\n

The gear teeth and the synchros all look good on this transmission:<\/p>\n

\"IMG<\/p>\n

\u00a0<\/p>\n

\u00a0The fourth gear isn\u2019t missing teeth, but the inside looks different compared to the other one (the one that looked \u201cwelded\u201d as shown in the A section):\u00a0<\/p>\n

\u00a0<\/p>\n

\u00a0\"IMG<\/p>\n

\u00a0<\/p>\n

The mating surface is slightly worn from this protrusion. \u00a0<\/p>\n

The question:<\/strong> Can I simply drop the entire shaft from this transmission into my other one? Or should I press off all the gears and put them on the other one\u2019s shaft?<\/p>\n
