Manual Transmission
Manual Transmission:
Brandon here, today I took apart the Muncie 4 speed transmission which is used to switch gears in a car. It had a aluminum case. It took 2 hours to disassemble. We used a press to extract the shaft. When we shook the box, needle bearings fell out. We also used a ratchet to remove the bolts and my dad showed me how to use the extension to quickly unscrew the bolt. We used socket sizes 9/16 and 5/8 to take out the bolts. I feel that this project will take longer than I anticipated.
Dad here, overall, we had some concerns before cracking this transmission open mainly since the shaft wouldn't rotate and the shift arms wouldn't move. This kind of seals the deal to pursue the TKO 600 transmission (5 Speed) which will bring better fuel economy, NVH (Noise, Vibration, Harshness), and reliability.
It was interesting seeing Brandon handle the ratchet and sockets through this activity. Clearly, I've had a lot of wrench time and learned all the secrets to make the tools work for me. It was fun showing Brandon how to leverage his body to gain a mechanical advantage when he felt he couldn't get the bolts to move. I think he is slowly warming up to the concept that I may have knowledge he could benefit from.
I know in some earlier post I made a plate to press the shaft out of the bearing carrier of the rear suspension. Since then, I've embarked on some other activity that required the use of a press. So, we procured a press through Harbor Freight (25% off weekend sale) which brought the cost to $75. I wouldn't recommend this for a regular garage but definitely useful for our minimal use...well worth the price.
Another activity we started this weekend was rebuilding the rear spindle bearings, brakes and trailing arms. This was not a quick activity since we had to pack the bearings with grease and select the right shim to provide the correct preload on the taper bearings.
We've opted for the offset trailing arms to improve tire clearance. This decision leads to a number of up charges that should be considered before jumping in fully. Since the trailing arms are inset a inch on both sides, the mono spring and rear sway bar needs to be special to meet these new dimensions. So, this leads to increased cost from the supplier since they are selling you less material...this is me being facetious (actually, its probably due to the low volume of parts sold).

| Brandon is in charge of this endeavor |

| Broken down to major components |

| Clearly this trans has seen water internally for some time |

| This thing has clearly had a hard life |
