Revising gear box
Hello miteinander!
The next step now is the revision of the gearbox. Are there any tips or hints that I should know before?

Re: Revising gear box
It's all pretty straight forward with the gearbox. Inspect all of the gears, change all of the bearings and shafts and if the gears are good you should be all set. Getting it in and out of the car is the hardest part by far. How's it all look in there?

Re: Revising gear box
Good day to you Werner,
If you go to this web site you will have all the information you could wish for, Tom Endy is very precise in all of his articles regarding model A Ford repairs, scroll down to the transmission section. Regards Brian. https://www.santaanitaas.org/tom-endys-tech-articles/

Re: Revising gear box
I second Ryan with that it is heavy and a pain to get in and out.inspect all of the gears and check for pitting.

Re: Revising gear box
Guten Abend!
Thanks for the hints! Does anyone know this part: https://www.brattons.com/transmission-shift-rail-bell-housing-seal.html . Is ist recommendable? Or is it possible, to do it with sealing paste? I can't see how to mount/ the function of the part. The teeth are not without caries. But it is not necssesary to replace all of them (€ 1500,-!). I will coat it with MoS2. The bearings I'l take some with seal-lips.

Re: Revising gear box
Werner,
The part you show is the real deal oil seal, made by Mitchell. It actually goes inside the bell housing, to keep the oil from leaking around the shifting rails. It is easily installed with the transmission in or out of the car If you look at the picture of the bell housing, you see it at the top. It is held in place by two of the bell housing to transmission bolts.

Re: Revising gear box
Werner -
Also remove the oil filler pipe and replace with a plug. The pipe in your photo would allow you to over-fill the transmission. The oil should be filled to the filler hole height. |

Re: Revising gear box
Werner's oil filler pipe looks to be the one w/a dipstick.

Re: Revising gear box
Thanks GRutter for the important hint!
Right, it is the dip stick variant. There is currently only a "min" mark there. After assembly, I fill in the dictated amount of oil and scratch the "max" marking.

Re: Revising gear box
Looks like a good accessory. Do you have a cutout in the floorboard to access the dipstick?
Also, I can see some spalling on the cluster gear. Might not be a huge deal but worth pointing out. |

Re: Revising gear box
In the meantime the stick is no more needed. Because I mount now sealed ball bearings. And the Mitchel seal system.

Re: Revising gear box
Guten Tag Ryan,
yes, the wooden floor has a rectangular hole that is closed with a metal lid. It is true that some teeth have cavities. (Could have been rust earlier.) I sanded the tooth flanks smooth using a 20.000 RPM hand grinder. Then coated with MoS2 varnish. The holes remain somewhat filled. Then the transmission runs quieter a little bit. The teeth front are also deburred and angular.

Re: Revising gear box
From that picture those sliding gears look great, better than the ones I reused. That dipstick is a nice add on, might have to get one. Do you have the car all back together now?

Re: Revising gear box
Oh dear, that's still 100 hours until the car is reassembled!
The seats are not yet covered, the steering gear is not yet finished with new bearings ... Today I finished the gearbox. I installed the Mitchel additional seals for the sliding shafts and also the sealing plate for the gear shafts. Make something on the universal joint tomorrow. Then I can start with the gear lever tower. This is a lot of grinding work because the shift lever ball and the slide lever slide were extremely worn and are welded on.

Re: Revising gear box
Use the adjustable strap around trans to dash board brackets to help support and hold
when putting trans in. Bob |

Re: Revising gear box
You have to lube your wishbone ball once in awhile,ford allowed shift rail leakage to lube it. |

Re: Revising gear box
Hallo,
at Fuzes: Sorry, but I did not understand this text. at Jack: Well, I mounted overhead the ball a felt and soaked it with hot ceramic grease.

Re: Revising gear box
I have another question:
I am considering whether to close the through hole from the gearbox to the clutch release bearing rail. I installed sealing lip bearings to avoid oil dripping. In my opinion, this opening is counterproductive. Because of the maintenance hatch, I can lubricate the rail well. Thinking wrong or right? Thanks at all!
