    Need some advice. A local friend has had this engine for some time, in a kit of parts. We are trying to fit the camshaft but can't find any markings for meshing the gear drive from crankshaft to the camshaft. I have downloaded the handbook from I.F and the index says page 5 has details for fitting the crankshaft. Unfortunately pages 5 & 6 appear to be missing from the downloaded handbook.
    Do we have to mesh these gears by reference to the valve timing or should these gears be marked with their meshing teeth. Any advice would be appreciated.

    Many thanks

    Perhaps a picture would help.

    Many thanks Roland,
    I do in fact have both these pages from the manual I downloaded from I.F ( 64 pages in total ) Yours are somewhat clearer. The download is missing pages 5 & 6 which, from the index refer to installing the crankshaft. I can't believe that the gears should not be marked for the meshing position. We can work back from your pictures but the side shaft is a heavy brute and may well have to be fitted more than once to achieve the correct position.
    Would you be kind enough to let me know ,if you have pages 5 &6, if they are relevant to my problem.

    Nice to hear from you
    Best Regards
    Ewan

    Here's P5 though not sure how much it helps. Timing these buggers seems to be a black art. black3(1).jpg

    Excellent Roland,
    We have been looking for timing marks on the gears. The top of your page 5 shows a mark on the camshaft and a corresponding one on the bearing housing, with the big end balance weights hanging vertically. That is very helpful, will remember your further comment when we try to time it finally. I'm sure you have written numerous books on Black Art !!

    Great help as always
    Regards
    Ewan

    Next problem. Does anyone have any idea where one might buy 4 off 7/8 in x 6 in B.S.W bolts needed to fix the outrigger bearing to it's base. Tapped holes so stuck with B.S.W. I have found 7/8 in studding and nuts as a back stop . Any thoughts appreciated.

    Many thanks

    I would suggest Williams Brothers in Sheffield, they still stock a fair range of imperial nuts and bolts etc.
    they may well post stuff out as well as deliver.

    Thanks Malcolm,

    Have already gone down the studding route. Not cheap and had to go to Suffolk to collect it, 100mile round trip.

    Regards
