NOT !

..but LOT'a head-scratching / pulling apart / re-re-assembling,  till I found out what was wrong.
 I'm too embarrassed to tell.


No use dwelling on the past.
.-)
SO; moving on (fastlike);
There's nothing quite like a table laid with fresh new
and reconditioned parts !



Yummy!


Tonight I'll install the valves.
 It may sound silly; but I'm quite exited
as it's the first time I do a side-valve.
Also be checking the piston-ring end-gap on the new pistons.


Here's another small improvement on this almost-seventy-year old engine.
Originally the notorious 'sealing'-rings between the cylinders and the in-take
is made of brass, which inevitably will  turn brittle and leak.
Don't really want that, particularly on a blown engine.

Indian Parts Europe has managed to have these
space-age-unobtainium thingies made:



..from some sort of nylon-like material that will not change properties
subjected to intense heat (and cooling and etc.).
You get them oversized and they are then machined down
to your specific (in this case ; home-made) intake,
for perfect fit.

Erh...click.


Assembled one valve/spring in the cylinder.
...measured the length when mounted/compressed

Then sat it up to measure the spring-load when pressing it down the above length.



...did the same thing but adding the measurement for maximum cam-lift.
Why ?
1) to check if all springs had equal load (and for future reference. I do keep a log book)
2) the second measurement for future reference if I want to mess with the cams.

...and in they went:




Marking the rings before taking them out to measure ring end-gap





Rocky: yes IPE has some great stuff to upgrade ones Indian,
and as I said in the intro here; he's help to me is beyond immeasurable
and he does let me use all his special Indian-tools.
He has them all, plus some really ...erhh......peculiar named ones, like this:  huh

Currently  d r o w n i n g  in work, so haven't done much here.

Kenneth made a couple of bushings for the gear-shifter, to hold the new shifter 'rod'.



..that goes into a tube under the tank,
to get it as close as possible, up to the left side handlebar. (without interfering).
At the rear an adjustable rod will connect down to the tranny.
Originally the shift is positioned at the rear/right side of the tank.

Just a mock-up, mind you: not the right shape yet.




Yep: running hand-shift / foot-clutch / manual ignition-advance in left-side hand-control.

Yours truly looking for evidence...



....that there's any sanity in rebuilding
and modifying a 70 year old contraption...



...and drag it thousands of miles across
the globe, just to run it a few miles on a pile of salt








Nope; couldn't find any

Lars,
  Yes I am making progress on engine and updates to chassis for tech inspection
 Nice breather, I just made one close to that with a special timing plug I had made. I should know this week if I have to tear engine down.

Glad to hear you're making progress Rocky!

Things slowed down here as I've been working silly hours,
but I'm free now so thing are flowing again.

Using this wide collection of shims and thrust-collars





...I finally managed to put together the transmission properly
and also achieve the right end-float




It was all a LOT of fun;
As I mentioned earlier; everything has to go through the hole in the side of the transmission-case,
so basically one throws in a bunch of parts and THEN put them into position/interaction
WHILE in there.



YesSir; had to do it a few times.




All piston-ring end-gap's has been set,
and tops have been tidied up,
so they're ready with new gaskets (James Gaskets)  and bolts





So; all in all; it's beginning to look like an engine:




Few odd jobs on the frame left;




.....the last few brackets will be welded to the frame this weekend
and next week it's off to be powder-coated.

 
So hopefully it won't be that long
till it goes on the dyno to set up carb etc.
