36 transmission rebuild
While the engine is still out I want to check the transmission and replace bearings, seals, and gaskets. With the help of Mac VanPelts book I have the transmission disasembled and now inspecting the parts.
This is what I found on the main shaft where the 7118 bearing rides on. What are my options? Does the mainshaft need to be replaced or can this be fix in any way? |

Re: 36 transmission rebuild
In 36 there could be 6 spline, or 16 spline for the low-rev gear to slide on ---plus whatever was done for past repairs (the innards of most any 32-48 trans can be put into the case)
A repair could cost much more than a used--or even NOS shaft |

Re: 36 transmission rebuild
I would not reuse a shaft with a bearing surface that looks like that. I have some good '36 gears, shafts, etc., that I have removed from transmissions that I converted to the later '39 to '48 gears. I am willing to sell any parts from those '36 gear sets. Send me a pm if interested.

Re: 36 transmission rebuild
I believe I have the 6 spline. 6 helical and 6 straight here is the whole shaft bearing still attached.
But sounds like I need to find another one. |

When we see that much wear...aka...lack of lubrication, be sure to check the inside bearing diameters of the input shaft and the cluster all should be 1.125/1.129 with a smooooooooooooooootrh finish. Charlie ny |

Re: 36 transmission rebuild
I would also check into replacing your pilot bearing....it could be worn allowing the input shaft to move up and down, which would aggravate the alignment on the roller bearing.

Re: 36 transmission rebuild
Great info thanks for the replies I will sure to check the inside diameter of the input shaft and cluster.
I do plan on replacing all bearings. I noticed a few places on the 7100 low/ reverse sliding gear , should I worry about these or will it be ok? |

Re: 36 transmission rebuild
Junk... most of these gears are readily available as NOS at a reasonable price. No way would I even entertain the idea of using this gear.

Re: 36 transmission rebuild
Those are badly galled spots that could further fracture. I would replace that gear. Same with the mainshaft.

Re: 36 transmission rebuild
I took the synchronizing clutch (old style with 6 balls and springs) apart to clean and inspect. Things looked good but now I am wondering about putting it back together.
Is there a special tool that I need? |

Re: 36 transmission rebuild
I have used something as simple as a modern, screw adjustable, hose clamp to position over those balls and tighten down enough to push the balls in against the springs. The ring cannot be too tight or it will not slide as the assembly goes together. A ring compressor may also work well for this.

Re: 36 transmission rebuild
If the brass rings in the synchronizer hub turn in the hub, then the hub is bad!

Re: 36 transmission rebuild
What is the best way to remove and install the main shaft bearings, front and rear. Is a shop press needed or can it be done another way?

Quote:
When installing, do not use force that translates that force through the ball bearings- you will dent them. They will not last. Use a piece of pipe that fits to contact the inner race. Drive on that. I also grind the snap ring end so that if I can remove it -if there is a next time... If you don't know what I mean, you will when you remove your first snap ring from the main drive gear (Front input shaft). Karl |

Re: 36 transmission rebuild
should the second speed gear bushing be replaced during a rebuild? Mine doesn't look bad but wanted to ask.
Are there any measurements I can take to check for wear? Part 7104 on the synchro assembly |

Re: 36 transmission rebuild
intermediate gear (from Ford repair book32-47
end play .004-.008 inside diameter -1.5575 to 1.5585 The insides of my 36 transmission looked similar to yours, i had a couple of 46 transmissions that I had hoarded when I had a 46---those insides I put in the 36 case to get the better syncro assembly---the free floating blocker rings work much better than the ones that are part of the sleeve |

Re: 36 transmission rebuild
Thanks for all the good info, it really helps.
I am trying to figure out how to replace the throw out bearing, I have a new bearing but want to make sure I take it apart correctly, don't want to break anything I want to get the old bearing off and install the new one. |
