I'm not exactly sure of what you're asking, the filler plug should be about even with the cone, maybe a turn past. The most likely place for water to get in the pump is through the "O" ring that seals the cone, install a new "O" ring and swipe a little RTV. I pressure test 30psi for 30mins. There is another possibility for water getting in through the double lip seal on the impeller shaft, but try the "O" ring first.

If the plug is going that far in you probably need a new cone, the threads on the plug don't wear out the threads on the cone will. Your also running the risk of running the plug in so far that you're going to hit the impeller shaft.

Sorry we got a little sidetracked and I've been at the lake, anyway back to your original question. The other place where a leak is possible it the double lip seal on the impeller shaft at the impeller end of the pump. Part no. 3.

I tightened mine until it was nice and tight
Is there is no thread bottom on the cone?
If not I guess I'd have to be impacting the shaft if the plug is nice and tight?
Thanks
it did not bottom out it goes right through

The plug on the pump cone is a tapered 1/8-27 pipe plug, it shouldn't go thru. As another member posted, Pumps should pressure tested to ensure the shaft seals & o-ring are sealing properly.
Yes, have you pressure tested the pump? Apply about 30psf air, and spray soapy water around the cone, look for bubbles, the cone "O" ring seal is the most likely place. I've only had a problem with the double lip seal leaking one time.

So then it is fine to tighten the plug until it is tight?
If I tighten it until it's tight, I will not be hitting the shaft?
I really don't want to have to tear 2 of these back apart.
Thanks
Just a heads up Lou, 30 PSI is way too much. Spec calls for Max 10 PSI for 10 min.

I'm not sure exactly what you're asking? If the plug bottoms out you have over tightened the plug, the top of the plug should be about even with the top of the cone. If the plug bottoms out, something that I've never seen, you'll hit the impeller shaft. If you look in the service manual, Section 09, Sub-Section 01, there is a picture of what it should look like.
Refer back to post 13.
If you don't believe me or others on this thread, PM Dr Honda, I think he'll tell you the same thing.

Lou, not that I don't believe you, I'm just trying to figure this out because I really don;t want to tear this apart again unless there is really an issue.
NPT is a tapered thread, which will seal and limit the threads from being inserted so far.

My question is; when I serviced mine the plug on the cone tightened until it was hard and quite tight, so based on the info in this thread either the tapered threads stopped the plug from turning like their suppose to OR I hit the shaft with the plug and that is what stopped the plug from turning and I'm trying to verify which it is so I can fix it it if need be.
As far as I can see in the service/shop manual section 9 sub section 01 is the table contents for the steering system (page 254 of 372). I did however find the cone plug in section 8 sub section 02 (page 207 of 372) and again later on but those are just pictures. The manual I have is the 1997 374 page shop manual, is it the same one you have Lou?
Can anybody verify that tightening the cone plug until it's tight will bottom out the plug on the shaft or that the plug is suppose to be tight in the cone because it has tapered threads, not because it's hitting the shaft?
Thanks
