Nothing staged here, this was my first view of the crankcases coming apart, and at last the crank and it's various components can be stripped and examined.
I like these short films describing your work during a day, even more than longer videos but made, edited and uploaded to RU-vid much later. Thank you.
It’s great seeing an expert like you tackle a job like the A65. In my day (late 60s, early 70s) I used to carry out my own repairs on my own bikes (BSA C15 - fitted Hagon cam, new main bearings, high comp 10:1 pistons, stronger rods, larger valves, etc) also Triumph 500 Daytona, 650cc T110, etc. (I.e my Labour was FREE). HOWEVER, your work on this A65 must be costing the owner an absolute FORTUNE in your labour costs! Would it not have been cheaper for him to find another A65 in good running order; or a spare engine?
You're assuming an spare would be in better condition, after all these years? One never gets one's money back on bread and butter machines, even on Gold Stars; a reason so many jobs get bodged in the first place.
Generally speaking no thrust washer with early (before 1965/6) A65's with ball drive side bearing. Bush has thicker flange for these motors. With roller bearing in it's narrow flange bush and a thrust washer. Both need shimming to 3 thou max end float between crank web and drive bearing whatvever it is (ball or roller). What you have here Paul is what I've seen a lot over the years with A65's, mixed bits that sort of work ish if you get me. A lot of A65's were blown up back in the day because of this. Early and later cranks are different too (Webs machined plus case to match to shift crank over, plenty of info on internet...), mixing and matching can work if you know what you're doing. Interesting that crack on bridge piece, any evidence a rod hit it? I've seen that to in the past. Great stuff so far!
Bet you are glad you split the cases , best to start from beginning and work outwards , the previous builder should have his spanners removed , permanently!!!.
@@paulhenshaw4514 I'm sure you will be plasti gauging them. At least it's apart now, so checking and repairing can begin. Looks like it might not be too bad.
