oil pump
Re: oil pump
Rick, I was thinking about that also.
The oil piston pin is a full floating design, so the pin can move and hit the bore. I couldn't see an easy way to keep it in place, not enough room to put a keeper or plugs. Was thinking about using a punch and staking the pin in place, but was worried about the pin getting stuck and not floating and spinning.
I kept mine stock, but polished and buffed the end of the pin, so when it touched the bore it would slide easier.
Keep a good oil in your car 20w-50 with Zinc and change it alot.
Should be good for another 70K miles.
How did you sleeve the bore and with what?

Re: oil pump
I would suspect if it was designed as a floating pin,that it was done that way for a reason. That trying to lock it could have some grave consequences. And if you had one eat up the bore of the pump that there was a problem,like maybe it had stuck and couldn't float.

Re: oil pump
Brad, agree full floating is better, the pin should rotate and keep wear even.
Honda was pretty clever, he had to keep price down so this design was a good way.
I think the biggest problem these Honda 600 cars had was owners treating them like V8 slow rpm engines. A motorcycle design with high RPM's, air cooled and engine/transaxle sharing the same oil is totally different.
Most of my driving is city stop/go driving, so the engine is hot and running but not going anywhere. I will change my oil every 2,000 miles or 2 months of use.
Like any machine, hours of use is more important than just mileage.
Still might use a straight 50W oil, like Brad suggested, since all my driving is in hot conditions.

Re: oil pump
Lyle;
I tried a steel oil pump rod that miles made, nice part. Then I had the eccentric on the drum sleeved with stainless steel. Miles made the piston pin hole in the rod a tad smaller so the pin had to be pressed in. I pressed them in and have not looked back on any of the ones I put together. several are daily drivers for over 10 years. Still running and making their way around San Diego.

Re: oil pump
Hi Bill, Miles is a good machinist, have seen some of his reproduction parts, very nice work!
In defense of Honda, they were trying to build a cheap car, so some of the parts are not the best design, all car makers deal with that.
I think the stock parts can last a long time if the owner takes care of the car. For most of the Honda 600's still on the road, they are 2nd or 3rd cars, not daily drivers.
The stock design is cheaper and pretty good.
If I was designing it and money was not a concern, I would make an over size pin and press the pin in the rod. Then ream the piston ID for a slip fit on the pin.
My 2 cents - taxes.
