Speedometer gear housing leaking

[Scott Engelhardt]

I can not seem to get my speedometer housing to stop leaking. I have resealed the old housing and I have replaced the complete housing and gear, last time I replaced the seals I tried putting silicon grease in the housing hoping to save the seal. I just can’t stop this from leaking. I guess I should mention it leaks at the cable.

Could you have mistakenly installed the pinion shaft seal with the lip facing out?

Not that I am above making mistakes, but I know they are in correct.

...maybe you did the same thing as me:
Mine was leaking from the cable, I had installed everything new, new cable, new seals etc....but still dripping trans fluid.

Then someone on this forum told me to press the little o-ring seal in really hard.
I was a bit unsure but you could feel the seal go down and bottom out, it was a lot tighter on the gear shaft than before.
Havent leaked since then.

I will give it a try

Is the tension ring in place? A 11/32" socket works well to install both pieces. I use a nut driver.

Good luck, hope that something does it! My Dart leaks around the o-ringed housing, nothing that I have done has stopped it. Am considering draining some trans fluid, clean and dry, then silicone the damn thing in. Nothing seems out of the normal with it otherwise.

Yes it is.

Try checking how true the cable turns in the input case of the speedometer cable. I have seen where the cable was kinked and damaged at the point where the input case meets the outer cable casing. That may put enough pressure on the speedo gear stem to make it leak.
