    LOL yea he thought he had a v-drive.

    But when bolts were missing they would not show up in the bilge a week later. To be instantly identified by the owner as to where they go.

    I have never lost anything off my boat or engine and it actually left the boat. I have been known to say we'll find it eventually. Most of the time a week later look down and there it is.

    Not me. Fact they joke about finding parts of my boat in the lake out here. Last thing I lost was the entire left side fuel tank filler...cap and all. They found it with a metal detector...guy even brought it over. "Knew it had to be yours." LOL.

    But I do like to throw a couple 3/8" bolts on the floor of Morg's boat...then watch as he tries to figure out where they came from. Keeps him busy.

    This thread is oficially hijjacked.

    Worst one for me was the key and floatie thing. Had to start it in gear with a screwdriver to get back. Luckily was running a mag. And Starter on the driver's side within reach LOL

    Found it the next week between the seats in the bilge. Same place everything else shows up. Even the tall breather cap off the valve covers. 3 times now lost one and I have no idea how it lands in the boat. Bolts and all.

    Actually not a hijack but rather a planned deal by me to get Slotracer so discouraged in building a blown motor that he will then sell me (cheap of course) that Cole Tr-1 1/2(as I call it) with the Lange bottom so I can see how much difference the bottom work did.

    well i am not ready to sell yet. the hub i have has is shaped with what looks like a counterweight on it. its not all the way around. the guy doing the machine work has built quite a few blown engines for alot of people that drag race. he has 3 or 4 engines that are running at sacramento raceway on tuesday for the new year day races. he has built engines for russio's in so. city. on the highjack side of things.

    But I do like to throw a couple 3/8" bolts on the floor of Morg's boat...then watch as he tries to figure out where they came from. Keeps him busy. this is just plain mean to watch someone look for the missing bolts

    Never said I wasn't mean.

    The hub sounds right. Yeah the weight is only on "one side".
    You can see some hubs here:

    Will be at CFW. Morg went to new store...I think he did some work out there. I haven't been yet.
    That is the counterweighted hub used for external balance cranks. Just be sure you put it on EVERYTIME in the right direction...as Info told you about. They work good single key.....ran them for years and years with blown alcohol power.

    It is easy done...because if using one keway....you can put the hub on 180 out. It will fit either way. You do it the wrong way and the motor is out of balance....big time. The hub goes on so that the counterweight part...is on the same side as the counterweight on the crank.
    In essence....you are "fooling" the crankshaft into thinking it's counterweight is heavier than it is. I hope that kinda explains it....rounda bout.

    I'll be there but my boat will not. Morgs boat won't be there either. We have to tow through snow and sand on roads and it is not worth it for a one day deal.

    but if the crank only has one keyway and the hub has one it should be the only way right?

    Look at the picture. It has 2 keys...180 apart. Click on the item for a bigger picture.

    Infomaniac post "Yea if you have an external balance hub with a counterweight, and there are 2 1/4 keys. The counterweight on the hub lines up with the counterweight on the crank."

    One other thing:
    If you want to know if the main saddles are straight in that block you are going to use.....then bring the block (bare) to CFW and I will bring my bar and check it for you. You have to let me know tho...cause I do not pack that thing around.

    Then be damn hard for you to get it on wrong. And it isn't a BDS. But...that said....I am sure you will have to 1/4" key over the existing 3/16 key slot on the crank. Your machinest will know. Any questions...bring it to CFW.
