rreford Posted March 21, 2004 Share Posted March 21, 2004 Went to local dealer to get a 3.9 (white 19 tooth) speedo pinion gear to match the 3.9 in my '78. They could sell the whole unit that fits in the tail of the tranny, or they had just the plastic gear and the shaft on which it is mounted. I opted for the latter since it was cheaper. Now I'm trying to figure out how to swap it into the carriers I have on hand. There is a pin driven through one side of the carrier that matches a shoulder on the gear shaft - I'm pretty sure that is what holds it in place. I'm having no luck in driving that pin out, however. Anyone done this swap, and can you tell me how you did it? I may go to the local JY and get what I need off an '82-'83ZX... Quote Link to comment Share on other sites More sharing options...
Ben Posted March 21, 2004 Share Posted March 21, 2004 The shaft is indeed held in by that roll-pin. You will notice the groove ~1/2 way down your new pinion ger - that is where the pin resides. Get the appropriate sized roll-pin punch to remove. Quote Link to comment Share on other sites More sharing options...
