    Hello,

    Oh no, not another Villiers....

    I've promised myself I would get on with the WX11 at one time or another. As I have most engines in an OK state, I hope to get my WX11 in bits and back to my shed this weekend.

    I know the big end is pretty knackered so was wondering if anyone has replaced the big end in one?

    From what I have gathered the rollers run in the crank without an inner or outer race, Instead of fitting OS rollers my idea was to have the con rod and crank pin machined so a cadged roller bearing could be fitted, or thinking a bit more on a budget could 2 roller bearings be pressed into the con rod to take up the width?

    I hope to get this back to it’s former glory as I remember it when we bought it in 1994… well that’s the plan, will hopefully be ready for August next year 5 years since we lost Percy.

    Cheers, Steve

    IIRC the big end is composed of off-the shelf items. At least they used to be. It took a while with the lists but I found appropriate inners, outers and rollers. Try a visit to Fenners or whatever they are called now.

    good luck

    Ok thanks Roland, There is a Brammer up the road from me so once I get the crank split it will approach them, will see if Patrick can squeeze me in before Christmas, if not there our others.

    Cheers, Steve

    Just incase there is any interest, I have managed to get some work started on Percy's WX11.

    We swapped it already restored for a Ruston 6PB with Villiers magneto, that was 1994, and we never put spanners on it.

    1st oddity is there was no C clips retaining the gudgeon pin, it just had 2 pads in either end but it was free to float! The small end is also a bit suspect, luckily I have a good spare, this was one of the jobs the previous owner had done.

    And finally the crank is out.

    This is where the main work is to be done, new big end is required, plus one of the main bearings are suspect.

    Thats it for the moment, will be done as and when, as it's done in memory to Percy, I don't know if to keep it burgundy or put it closer to the original green.

    Cheers, Steve

    While I decided what to do with the big end (mainly where to send it!) I started the clean and strip the paint.

    The Exhaust base went up quite well once I introduced a new blow lamp...

    I then got some of my old faithful carb cleaner and turned to the crank case halves, it sure does a good job of cutting though the old 2 stroke crap!

    They paint seems to be coming off OK, it is a bit stuck in places.

    The block and flywheel have a bit of original paint left. So I might try and scrape the red off slowly and see what we are left with.

    What does the congregation think, is there enough paint left to do a "working clothes" job and coat with boiled linseed oil? I quite fancy doing it that was as the idea of doing this engine was to preserve Percy's memory (well for me) and the fact I could preserve a bit of history in its original paint that is a bonus.
    The big decider is the tank isn't the original and is made of brass, so might look a bit off strapped to the side of a working clothes engine.

    Cheers, Steve

    If you are doing it in memory of Percy, I'd be trying to replicate that first picture, but that's only my opinion.

    Yes that was the initial plan, and the lack of original paint on the tank and hopper is making me think I should stick to that plan, though as it's been "handed on" I do think I should put my own twist on it.

    Cheers, Steve

    Edit: Yea I'm going to repaint it, think it will look naff with a plain aluminium top, home made steel tank and little bits of original paint, if it was the original tank and the hopper still had some paint it might be another story.

    Cheers, Steve

    I've had this picture sent me over on Fozzers forum of a WX11 con rod and crank pin split down.

    [​IMG]

    It doesn't look like the crank pin will take a caged bearing easily, So looks like the crank pin and big end will need to be machined true and O/S rollers fitted.

    Narrows my options down a little but fingers crossed we can get the correct size rollers.

    Cheers, Steve

    Oh an idea that popped into my head, is to machine both round making the Big end oversized so a bearing out race can be pressed in so 1/4" rollers can be used again.

    I got a scrap WX from Astle a year or so back and if I remember right the big end is an 8 piece item, i.e the washers and spacers all split down to individual parts and the bolt slides out. Might be wrong but I can't remember seeing that as 1 part.

    If the washers split come off the crank pin that might make it a bit easier as I can then fit a full bearing, will see what I can get sorted on Monday.

    Cheers, Steve

    As I previously indicated it is possible to buy seperate inner and outer with loose rollers which the washers serve to contain. It will take careful measurement and a fair amout of time and effort poring over a catalogue. Should an oil hole be needed then a small die grinder to go thorugh the case-hardening followed by a drill will often suffice.

    good luck

    Ok Roland, Thanks.

    It was unclear to me from the photo if the bearing retaining washers are separate or one piece.

    Cheers, Steve
