gasguzzler....please add your car info to your signature line......I can't remember if you are the one with a 3rd gen or 4th gen.....

I THINK you have the 3rd gen (86-89). If so you only have one belt.....and continue to read

Yes, the gear/guides slide off and "bam" there is the seal. Again if this is a 3rd gen, while there I would replace the two oil pump o-rings....Yes two.

Yes it's a 87 2.0 carbed LX. I tried to edit my sig. but it doens't appeat to have worked.

So there's no bearing cap or anything to unbolt in order to get to main seal after removing Tbelt sprocket. That's good to know. As far as the orings I have no idea where those are. Can you elaborate? Thanks

Edit: I guess it did work! lol

Final thoughts on seal install
 

Based on your post, you have a completely different engine, but as a final thought I had a lot of success pressing in the crank seal using a short length of PVC pipe. 1 1/4 fit well under the crank bolt's washer and the gasket could be pressed in by a slightly larger 1 1/2 pipe. I used a very short section of 1 1/4 and had a 1 1/2 x 1 1/4 coupler that quickly changed size for me. When the pipes were joined, the total lenght for me was about 2 3/4" long. the new seal pressed in easily and it actually went slightly below the case.

For your seals, check out bernardiparts.com or majestic honda online parts. you can lookup for your model. looks like you have two, maybe even three orings for your oil pump. I think the numbers on the sheet were 4,10,11. sorry I couldn't post the link. Two normal round orings and the other has another piece of rubber crossing the center. All seem relatively inexpensive.

corrrection, 4, 9, 11 10 I think was a small oring for the oil tube. All the junk posted at the end was a paste of their part numbers. sorry.

And that is what I get for going from memory...yes three and dang I did this in Sept of 2011....really loosing it. I was one of the last days I got to spend with the boy

For one of them you have to "open up" the oil pump....that one might be over kill, even though I did it on the 89 LXi because, I was there and it has over 200k, why not.

I think I'll buy and have all this stuff on hand before I start on it and decide how deep into it I need to go based on how things look and how things go.

Thanks guys for the help.
