The Honda mechanic has ben sick, so I decided to go out and pull the lower unit and the old water pump. It took roughly 3 hours. That's definately where the coolant was getting into my Oil, and I flushed the engine, and I got 1'8 inch of slude off of the bottom of the lower front unit! The water pump itself is gone. It wiggles about 1/4 inch sideways, and1i/8 up and down. I did number my bolts, and put then in order. Was a total of 14 on the 83 Aspy.
I am going to order the lower unit shaft gasket, the Gasket for the wter hose cover, the oil shaft 0 ring for pump shaft, the 2 bigger 0 rings tomprrow. There wasn't even an oil oil ring on the old one. Was worn too bad, and it probably was chewed up. I got the good water pump out of my old parts bike. Looks ok, according to the Honda Mechanic. I was worried about the U gap where the water pump shaft goes over the oil pump shaft iuntil I seen the one I pulled off. Also, Thats where a lot of my noise was coming from. I'm just glad it did not run hot. Gonna put an oil dipstick on it and keep tabs on it every day. I thought it would be difficult, but a piece of cake.
Tommorrow, After I get back from the doctor, I'm going to start cleaning the old asket off, and get ready to put her back together again. Even the radiator was a breexe. Now, I will always take it loose or off when changing belts. Live to learn!

P.S.
I did not know that to change the ratio from an 8o to an 83 was simply to change out the rear unit. (Where the tire mounts) according to the retired Certified Honda Mechanic. I thought the transmission had to be changed also, and he said no, They didn't. If I can find one to go on my 80, I think I will get one. At 3000 RPM's on my 80, I am at 45Mph, I believe. On my 83, ay 2900RPMS I'm at 55 Mph.

I guess it is the unknown. I got to lie down all through it. I took the oil bolt out of my oil cover, and screwed it back into the lower unit, and broke it loose by pulling the Frack out of it. Finally, anter it got unstuck from the dowell pins, It slid off effortlessy.
I do have one question though.Is there supposed to be any oil in the lower front unit? After I got the water pump out, It was very easy to see where the coolant was getting the oil. On my parts bike, there was some oil in the bottom of the front lower unit. Is this normal?

William_86,
I stil cannot get enough gusto in my shoulders to change my rear tire and wheel out yet. I will figure out a way somehow though! (Mabye)

It's great when you figure something out and everything falls into place.

Your mechanic may have "retired" part of his memory too... None of it is a rear end issue, and all of it is the transmission.. I'll be back with the "numbers" (that I have posted before:waving:)

found it..




The final drive ratio is the product of the various ratios...

For example, the 1980 in 5th gear is

1.708*.973*.909*3.091 = 4.669

the 1983 in 5th gear is

1.708*.973*.829*3.10 = 4.271

a 1980 in 5th gear with an '83 rearend would actually be slightly worse than a stock '80

1.708*.973*.909*3.10 = 4.683

Actually the ratio of either is so close to the same you wouldn't notice a difference.
