    45 Rebuild

    Rather than keep starting new threads, I will start off this one and keep adding new Pictures as the build progresses or you all get bored and beg me to stop. May be a real long post this one.

    The threads on the rear wheel adjusters have been re-tapped and metric bolts fitted. I have 2 options.

    Option 1 was to insert an Helicoil, which would need to be fairly long and as always, be part of an expensive kit, where you only need 2 inserts.

    Option 2 was to drill and tap out to the larger size wheel adjuster for a big twin. This is the way I decided to go. The big twin adjuster was 3/8-24.

    I tried to go straight in with the 21/64 drill bit, but this proved to be a bit much for my cordless. Plan B was to step it up in stages

    I started with a 19/64 then 5/16 and finally finished off with the 21/64.

    The next step was to tap it with the 3/8-24 tap.

    Last one was to try the big twin wheel adjusters. Seems to have worked a treat.

    For those of you that are interested in this project, I will follow this one with the engine rebuild. As stated before Leigh ( Topper ) as been undertaking this part of the project. I will update the Pic's and a bit of text. But any detail Leigh may have to answer.

    Keep it going Gary, it's a great thread (no pun intended!). I,m still poncing about with my carb, but that's the joy of it for me.

    Cheers,

    Yes. Keep it going. I like tech and rebuild threads. I shall follow it.
    Once I get sorted I shall be starting one of my own, on my 75 FLH re-build.

    Re: 45 Rebuild

    Right here we go with the engine thread. The old thing looks a little sad and worn out. Probably the under statement of the year. Removed from the bike and sat in the home made engine box. Heads off.

    The cam cover and case has been drilled out to mount a 12 volt generator, such a criminal act. But then when this was being ridden every day to work in the 50s-70s it would have improved the lights and charging for a daily rider. Still a criminal act.

    The cam cover as damage at the bottom where the oil pressure switch screws in. Looks like a new cover is on the cards.

    Re: 45 Rebuild

    The next steps was to take it up to Leigh and strip it down. As you always do, I was hoping for some good news. No such luck, I went up with a complete engine and come back with this.
    Basically a load of trashed parts.

    Both of the fly wheels were damaged as well. One of the fly wheels was that worn, that 2 thrust washers had been fitted to take up the slack, where they would normally have been one.

    When it finally let go and gave up the ghost it had taken a chunk out of the Con rods.

    Next check was the cylinders, these had some strange pistons and had been bored out to plus 90. Totally shagged.

    The decision now was to either spend £3,000 on a reconditioned engine or start with this one. I had loads of conversations with Leigh and was not sure which way to go. Pretty pissed of at this point. After Leighs kind offer of helping with the rebuild ( loose term he was actually doing it )was the way forward. If I was to buy a recon engine, how good would that be. If I got all the parts at least I would know they would be new, NOS or decent OEM parts.

    First thing was to check with 45 parts EU to see if Larry had any Fly wheels, he had one NOS left hand one and one OEM right hand one. He said that the right one, was normally the one which was worn out first, as this side is where the thrust washer lets go and spins on the fly wheel.

    The next job was to find 2 cylinders, there was a pair of NOS ones on USA ebay, but they went for silly money. After speaking with Jeff at Riverside he said he had quite a few old ones. A trip to Putney and after sitting on his work shop floor with a micrometer I found 2 cylinder +40. Both would need honing and new guides, but it was a start.

    Re: 45 Rebuild

    That's a bummer about the shagged parts. On subject of 45 cylinders, have you seen those on gaybay what are made in India? I wonder just how good if any these are.

    I have it on good authority from the guy who owns my old 45, that the Polish ones are better. i'll try and find out where he sourced his.
    Much less involved.....

    Re: 45 Rebuild

    I am unsure about the one Kev as refered too, but will say I have been told that the ones from India and not good. One of the large suppliers of 45 parts will not stock the ones from India. I do not have first hand experience though just what I have been told.

    Re: 45 Rebuild

    Following this with interest Gary. I doubt I will be able to contribute though but I aim to learn.
    What is the bikes history as far as you know?

    Chaz.
