Speedo drive gear question

johnnyalkiMember

My angle drive gear is loose on my 72 Pre-L. It's the large nut that attached the assembly to the ZF. Is this the part that causes bad things to happen if it's loosened? It seems that if I turn this nut counterclockwise it will pull the angle drive closer to the block and tighen it. Is this the case?

Thanks in advance for your help.

...NO!! I turned Mine CLOCKWISE to tighten! But, There wasn't enough Room to get 'That' big of an 'Open End' or 'Cresent' Wrench on it, until, when I had the Engine and Trans out of the car. Maybe You'll have better 'Luck'. It was loose about One Turn; for a long time. I doubt that there was any damage done...

thanks Marlin.

I did get it tight. Unfortuntely, the speedo still wobbles and now there is a tick-tick-tick sound.....any guesses?

thanx,

...Yes, could be the cable just needs to be greased. I just shoot some thin oil down inside from the rear. Also, I was 'told' long ago, that a 'whobbling' Speedo needle, indicates a broken tooth on the plastic 'Driven' gear...

Marlin,

is the "Driven" gear in the speedo or in the angle unit?

...The 'Driven' gear would be IN the Transaxle, on the shaft that the angle drive attaches to. When I was told, by a knowledgable friend, about a broken tooth being the cause of the speedo needle Fluctuating; He was generalizing about all (Mostly American Cars) speedometers, where most all of the driven gears are made of plastic and not just about Panteras...

Update...

I attached a hose to to the cable by the ZF, sealed the hose with duct tape and filled with oil. I let it sit overnight. I went for a test drive this morning. No more tick-tick-tick and the woble only goes about +/- 1 mph. A very big improvement.
