Thanks La Verne, I really appreciate your information ! I thought about it but i didn't understand why , with your confirmation I will be able to continue the assembly . Another question ... Do you know what the brass screw and the nut are for , on the side where the connections are ? I thing it's to adjust the position of the armature but there I'm still not sure . Thanks again.

It's to adjust the free play of the shaft and I would imagine there is a spec if you could find a repair manual for that unit it would tell you what to set it at.

Thanks LaVerne. I found the problem of the wiper motor heating up . The too small fiber insulator on the brush arms , which are used to attach the spring were replaced by two similar ones cut from brass shim . Also I have I have transmission oil leak ... After filling it I noticed that the leak is located below the flywheel at te back of the engine oil pan, there is a 1/8 hole with a cuter pin and the oil leaking from there ??? If anyone knows what the problem is let me know !!! Thanks

More than likely that oil is from the engine and not the transmission

This morning I will check the transmission oil level to see if the oil is coming from there or from the engine . If it is from the engine were can the oil leak ? The thing is that the engine and transmission have been rebuilt, and I ran the engine for adjustments and there were no leaks . After two weeks I filled the transmission with oil and the oil started to leaking. Its unbelievable that gearbox oil can leak in this place.

Probably coming from the rear of the crankshaft, very common once a little wear in that area becomes evident. A modified modern crank seal can be installed, but it's an engine out job. PJ

There is a seal on the gearbox input shaft but if it was properly replaced it should not be leaking there and they generally do not. The rear of the engine is another story. There wasn't any seal on the rear of the crankshaft as we know them today but instead an Archimedes screw/scroll affair
that if installed correctly should keep the oil in the crank case when the engine is running. When the engine is shut off they will generally leak a small amount into the bell housing area and eventually to the breather/drip hole on the bottom of the bell housing. Many including myself have installed a modern lip seal on the crank flange. The results reported by others can run from seals great to very poor. The installation again is critical to achieving good results.

Since you believe it is the gear box I would suggest you put some purpose made oil dye in the gear box and see if the dye shows up in your leak. In either case the offending item will have to be removed from the car for repair.

This morning the transmission oil level went down to half of wat it was yesterday. On the oil level indicator (oil stick) The oil was on the high level line and there was an oil leak , this morning the level is in the middle of the space indicating normal and there is no more leak . My question is ,there was too much oil and how is it possible that the oil is leaking from the transmission ? Thanks

The bell housing mounts to the gear box with 6 bolts. There is a recess cast into the bell housing for the front seal I had mentioned above and if oil is leaking from there it will drain down through the opening at the bottom of the bell housing. The gear box will have to come out of the car for repair.

Wen I rebuild the transmission I remember deforming the seal and ad to order a new seal ,now is it possible to leave it because the oil level is normal ?

What do you think?

The transmission oil level is in the middle of the normal indication on the level indicator . I removed the oil and measured , it give me .400 ML and with this amount of oil there is no oil leak, is this enough ? The oil seal on the first motion shaft is new and the shaft has never turned . I must say that I used a .500 ML syringe to pump the first .350ML of oil it was easy for the second .350ML it was difficult I had to apply a lot of pressure on the pump. I believe that the pump tube was pressed on the gear box casing where the shifter shafts pass into the bell housing, and that the oil flowed between it and the gear box casing through the slot which is located between the cavity for the shifter shafts and the housing of the oil seal. I probably opened the oil seal with the pressure or I broke it, can I drive safely with .400ML ?
