'95 Civic DX D15B7

So, the other week I replaced my tranny input shaft bearing. I was careful and followed a guide from the FAQ here. The bearing was definetly in need of replacement. I didn't inspect the rest too carefully, but what I saw and turned seemed ok. Put it back together with the Hondabond, let it cure, etc.

When I added the Honda Genuine MT fluid, at the very end when it was full, a small bb flowed out.

The car shifts and drives fine. I'm not going back in there soon, thank you very much.

I am curious, anyone have any idea which bearing it might be from? How worried would you be?



Just under 4mm diameter.

 

Could have been one of the ***** inside the old isb that fell out and you didnt notice. That or one from the mainshaft bearing at the top of the shaft.

 

There's a bunch of steel ***** used in the transmission:

 

Wow I didnt know they used that many. Thanks for the info Ron.

 

Drive it till It breaks then fix it if you really don't want to redo it again now lol. You would believe how much a honda can take.

 

Yup, look at that, it was probably one of those. Thanks. (I think the ISB ***** are bigger too, but I threw it away before I refilled the fluid anyway)

Yeah...I don't know when I will have time to get back in there. Sooo, if it breaks I will fix it then, lol. Or maybe if I get done with all my other car projects first.

 

I've taken apart and rebuilt a bunch of these transmissions and I can't ever recall seeing a bearing that small.

 

Yup, then it is probably one of those steel *****, not a busted bearing. Still not good, but I feel a little better. It looks fun trying to find which one is missing.

 

Question: How did the bb flow out when you were *filling* it? Don't you do this from the top of the tranny?

 

No I mean literally nothing in there is that small. All the detent ***** are about 5/16"/8mm I have no idea where that came from, but it wasn't supposed to be in there.

 

I use the proper fill hole with the car level on 4 jack-stands. When the fluid is full, it overflows a bit. That's when it came out. I didn't have a tube and funnel handy, so I used a pump attached to the MTF bottle with the plastic hose stuck in the fill hole. But yes I was above it looking down. I do realize a funnel with a tube would be easier, but it was easy enough.

Does that answer your question?

 

Ah, I see. That's good, I guess.

 

I think the question concerns the conundrum that a dense steel ball would eject from the fill hole by floating on the top of MTF.

 

True, true. I guess it was just close enough to the opening and the flow was strong enough that it came out on the current. Or something. It doesn't weigh much anyway. I didn't put it in there or anything, I was careful to keep it on a clean garbage bag, and a clean tarp when I took it apart and put it back together for the ISB and oil seal for the ISB.

Well, I guess I won't worry about it.

 

I guess it somehow could have come from the new cheap fluid pump I was using, or one of the MTF bottles, anything is possible.

 

Most likely it was from your transmission, not the MTF you used

Did you keep track of the steel ***** underneath bolts (mentioned above) during the rebuild? I almost lost one when I rebuild my transmission, it's easy to forget one

 

It wasn't a rebuild, only an input shaft bearing and oil seal change. I didn't have to remove any steel *****.

94EG8 above said nothing in the tranny is that small.

It works, so I will drive it until it breaks.

 

OK, I investigated the pump I used, and guess what? This piece of **** was the cause, and it was the first time using it. It was some cheap tool from the parts store. Next time I will get some tubing from the hardware store big enough to go on the end of a funnel.

Here is a view looking at the bottom of the pump, there is another ball waiting inside. This is where the tube attaches to go into the bottle of fluid.



The package should say "steel ball insertion device for your vehicle."

 

Glad you got to the bottom of it. At least it fell out instead of floating around your tranny.
