Grease Fitting and Bell Housing Question

[dmdeaton]

I am in process of restoring my bellhousing. New pedal shaft and bushings. I removed modern style grease fittings from the pedals and they were not installed very well. Someone replaced the pressed in originals with new style. Looks as if they just wrenched them in the bore without tapping. I would assume you tap with the proper thread size before installing new ones? taper or straight pipe threads?

Why no grease fittings on the throwout bearing shaft? Just lather it up for a one time rebuild? Is this to keep from over greasing and pumping into the clutch and flywheel?

you can get drive in new style zerk fittings..

I grease the shaft when I assemble it, then squirt oil on it when I grease the car. That should keep it well lubed.

Original pedals did not have grease zerks until late in production. I have added new style fittings to one set. I also added zerks for the throwout shaft bushings on that one. No reason they can not be added if wanted. Most survived decades quite well without them. Rod

Take flex copper tubing and thread the outside. screw into the part. cut off flush with the surface. press original grease fitting into the tube.

The thread on the screw-in fittings is 1/4-28 machine thread

I think the holes for those grease zerks are a pipe tap. I drilled and tapped holes in the clutch and brake pedals. I use a 1/8" pipe tap.

The itty bitty ones are 1/4-28 machine thread. I just installed some on some pedals
the next size up is 1/8 NPT, but they are kinda big for the pedals. They will work, tho

[dmdeaton]

I forgot about the press in replacements
that is probably what these were
the bag of new replacements from the vendors has the press in style
looks like they just grind the threads down some
or don’t cut the threads as deep

[CM2]

The press in new style is the same diameter of the original alemite fitting

Thanks again guys
so much info

My car did not have the grease fittings on the bell housing, but when I had it apart, I drilled and tapped and added them to both shafts.

[Larry Jenkins]

Rather than try to insert the split shaft bushings in my Bell Housing, I ordered some Oilite bronze tubing from McMaster-Carr and made some on my metal lathe. Never need grease. "Oilite" is a brand name for oil impregnated bronze tubing.

that is a slick way to go, no pun intended!

[Larry Jenkins]

You would be surprised at how much oil was coming out during the shaft assembly. Will last forever. If I had to do it over, I would probably try to make all the bushings from Oilite. King Pin bushings come to mind, even though there are zerks..
