    Don't be rotten, you lot!! I'll have you know that that nice Mr. Crispey bought me a most yummy sausage sandwich and a pot of tea when we met up while he was doing his World Tour of the UK a couple of years back. A gentleman indeed.

    Looks like a really fun project, are you posting video on the tear down and build as well?

    At long last with all the issues i had with the head and a oversize right hand crank end the crank has finally been ground and balanced and should be back soon, as its nice n warm out in the workshop i decided to inspect and clean the rocker shafts and fit two new ends to the rocker shafts that had been butchered years ago.

    Well at long last i have all the parts back after Pat at Seager Engineering finished off the crank grind, balance and other work to the oil feed end and machined the outer cover for a seal instead of the original bush. Spent a few hours this week assembling the bottom end when it was warm enough in the afternoons to do so.

    Lovely job Sir. Does the work on the oil feed side of the crank require smaller inner diameters in the new bearings or has the work kept the diameters at the original size?

    Just so nice when the motor starts to go back together. Particularly given what you had to do to get it apart.

    The crank end had been worn along with the failed bush but size wise they are the same :)
    Edit must read reply's more slowly lol, yes the odd sizing issue was dealt with but it should have also been the same as all one piece cranks on 650's with the bearing fit and Pat is not sure what had gone on with it previously, another mystery :-(

    Bit warmer today so cleaned and painted the barrels, fitted and timed the gears along with a new Morgo oil pump, also fitted a new crank retaining nut as the last one had some huge gouges in it from the last time it was apart.

    It's pretty rare that I ever reuse the crank nut. They nearly always have been abused with a hammer and chisel at some point in their life. Same goes for the crank ends, hammer wise.
    Looks nice going back together. Morgo pumps are worth their weight for sure.

    I've often wondered about doing the barrels a different colour, like a deep navy or purple, shiny black is the fastest though.

    Yes, I have a crank that not only needs grinding on the journals but the bearing faces are also rusty. I've not had that issue before as they are nearly always protected in the bearings.
    I've still to talk to an engineering type person about it as I'd rather use a new same sized bearing rather than find an odd sized one to fit a machined face. Can they be built up with weld and then machined?

    I have never had to build one up but there are a few different ways it can be done, as with anything like that i just give to others to do lol

    In my days as as a maintenance fitter that was quite a common task. Not on a crankshaft granted but many other bearing surfaces.

    Welding and grinding back to std sizing on crank shafts is doable ! My Father a WO1 in REME worked on Tanks in Germany , he was in charge of the main wksp in Germany. They had special sealed welding chambers , early form of mig and tig welder's , they did crank shaft rebuilding in them !

    Making the most of the warmer midday Sun, new lifter blocks and lifters fitted, rings gapped and pistons fitted, barrels fitted and started timing distributor, got a bit chilly so will finish later.

    Nearly there, cylinder head, pushrod tubes and pushrods back in and crush set between rocker boxes and tubes, just have to prime the bottom end and fit timing cover next.
