915 rebuild Questions
Well I am spending Easter morning looking over all of my 915 internals. It is a 72 with the sealed guide tube. The Transmission shifted fine with the occasional grind going into second. My problem was that both seals where leaking thus I decided to open her up and inspect everything while I was in there.
To this point I have used all of the previous posts(extremely help-full)!! I have both the shafts out and laying on my table. I have all of the gears etc off of the input shaft using the bang the end on the garage floor method. Here are a some cloudy pictures of my progress.   stacks on table...   I inspected the input shaft and decided for sure to replace all syncros and dog teeth. I really want to get a good look at 1/2 but I am having trouble getting the number one roller bearing on the pinion shaft to budge. I have been attempting to use the method shown in a previous post using two pieces of wood to support the shaft by the first gear. I assume you then hammer down(rubber mallet) on the top of the shaft. Will this do damage to the speedo gear? Any other methods for getting this gear off? I can't bang this on the garage floor can I? The speedo gear just looks so brittle. Also I have three 915 axles in unknown condition. Is it feasible to borrow parts I.E. sycros or sliders etc? Do I need to do it in groups as all of these parts have meshed together? Any help would be greatly appreciated.

"Any other methods for getting this gear off?"
Use a hydraulic shop press to smoothly apply the required forces; support first gear on brass, aluminum, wood, hard plastic (ABS plastic pipe) or other soft but sufficiently strong material; press against the speedo gear through a "pad" of hard plastic. 1st and 2nd gear synchro/slider/spider parts were pretty much interchangeable through 1976; after that there were changes. 3rd through 5th and reverse parts will likely interchange from 1972 through the end of production. |

you might want to see if there is a way to upgrade the sealed guide tube...
