So I guess I'm resting my case as well . . .

What color is the case. Yellow?
G

 

Hmmmm . . .

Not yet.

Might be nice to paint it up in something other than MOWOG green - you know, that metalic drab WWII surplus paint color BMC slapped on their castings until it ran out - about 1965 or so . . .

Hmmmm . . .

I'd be able to tell where the oil was leaking from . . .

Hmmmm . . .

Anyway, Fordboy - A quintabazillion thank-yous for the drawing.  This is huge, and near as I can tell, the only one ever put out on the interwebby to share with other A-series guys.  You've done the world a tremendous service - now we can ALL dyno our Spridgets and Minis, and find out how much horsepower they're not making.

 

Re:  Intermingling of the species......

Midget,

Thanks for the thank you's, but I'm not so sure it's huge, or, that it is a tremendous service to the world.....      It's kinda' like in "Miracle on 34th Street", where the lawyer (John Payne) proves to the New York courts that Kris Kringle IS Santa Claus.   Once he has had some time to reflect, his attitude is:  "I'm not so sure I did a good thing......."

OR, maybe I'm just the Dr. Frankenstein of 4 cylinder race engines......

Undoubtably I'm just another Prometheus, who probably has not been tormented enough yet..........

INTERMINGLING OF THE SPECIES.....  AKA,  DYNO ADAPTOR PORN!!!!

Little Tommy, er, Midget......

At long last:  illicit mating of BMC to Chivalay......    (Rumored to be penalty of death in most Star Systems, probably too pleasureable.......)

Dyno adaptor shape, dimensions to follow.....

Re: Intermingling of the Species,  Final Chapter.....

Midget,

Final version of what is required for lustful BMCs to intermingle with Chivalays attached.   Includes dimensions, tolerances, material specs, and a graphic representation.......

For anybody who cares:  This adaptor plate will allow inline BMC 'A' series engines to be mounted/adapted to dynos utilizing a Chevy scattershield/bellhousing.  Other items are required to facilitate a complete dyno setup, ie, front engine mounts, flywheel adaptor, etc, etc, etc.  Further adaptors are required to facilitate dyno testing of the Mini-Cooper variants.   Uncertain whether this adaptor will fit Mini gearbox/lower sump.   This adaptor was designed for a Superflow 901 series dyno, but may work with other dynos/absorbers.  Caveat emptor.

Gotta go, thought I heard Intergalactic Storm Trooper boots.......

I think I'll make one in case MM someday wants to run his engine in I/StR.

Wait, never mind.  No such critter.

Hey, EVERYONE –

This is important –

I owe a HUGE debt of gratitude to Fordboy for this one.  He hasn’t complained, but what he started off with was a VERY OLD version of an AUTOCAD file which had the Chevy dimensions in it.  My other good friend, Bill Alexander Jr. offered up a somewhat more modern edition of the software in order to pull this file out from the depths of the digital scrapheap that is Fordboy’s DOS based antique computer, and Fordboy PAINSTAKINGLY entered the BMC dimensions as an overlay.

I’ve mentioned Bill before – his father was the man who constructed the wood rimmed steering wheel I originally ran on the Midget at WOS in 2010.  We lost Bill Sr. about a year ago, but the Alexander family has been a huge intellectual and emotional support to me over the years, and as close to family as I have in the area.  Bill Jr’s mother, Pat, is the woman I’ve called “my Mom away from Mom” ever since I moved to Wisconsin.

Bill works in the construction trades, and the version he has uses dimensional inputs rather than engineering inputs, so every time Fordboy entered a dimension, it needed to be corrected each time he tried to save a file - something Fordboy did with the grace and perseverance he would prefer not to have publically acknowledged – we all have reputations to defend.  I’m sure this one drove him to the fridge more than once.

Bill, I know you check this out from time to time, so please consider this a public acknowledgement and thanks for your help and your enduring friendship.

Fordboy, you’ve just posted up what is likely the only accurate drawing for this application available on the web.  We both know that our suppliers are unwilling to share this information, that the engine has no commercial racing purpose, and that the people who know this information – transmission conversion folks and dyno shops specializing in this type of information, are unwilling to share it.

Ladies and Gentlemen, may I present to you, for those of us in the BMC community, the Rosetta Stone.

Fordboy has cracked the code.

Thank you, my friends.

Wait, never mind.  No such critter.

I guess I'm not whining too much, but if folks are pushing for a "Classic Bellytank" class, and an "American Gas Roadster" class, I don't see an issue petitioning for a SMALLER engine class in any of the pre-existing categories.

Midget,

How about an engine adaptor to fit a turbo Hayabusa 999cc to a MG Midget (or Datsun??) gearbox?   What class would that be?

Oh, wait.....  driveshaft, diff and axles suspect for real HP.......

Might as well race something diecast with 4 valves/cylinder to begin with.......         Renault R5 Turbo!!!!!!!!   3576 Frenchmen can't be wrong.........

If the French electorate is any indication, as a group, 3576 Frenchmen would quite likely be wrong.

As to Boris and Natasha, there's a ZIL plant on the steppes outside of Leningrad that I'm sure we can arrange have them sent to.

No, if we're going down this path, this is the engine I'd source -

http://en.wikipedia.org/wiki/Rover_K_engine

Destroke the 1.4 DOHC to 1 litre, put it in the Midget, and REALLY push the I/GT class.  It's a legal swap into the Midget, and I would have gone this way if I could have found one here in the States.

[Milwaukee Midget]

Okay, I’ve been poked and prodded into a complete posting of my ineptitude, so let’s all settle in for a good chuckle.

If Fordboy is Prometheus, I am Sisyphus.

Here’s the front of the mainshaft, with the gear and cone in place.  Note the pin pointing up about 1 o’clock.  It is spring loaded in the shaft.  In the lower right hand corner is the locking collar which retains the bearings and gear on the shaft.



That pin needs to be pushed down and the collar slipped over it to lock the gear and cone in place.  And of course, the spring is very stiff, a jeweler’s screwdriver won’t clear the lip of the cone, and a paperclip isn’t strong enough to push down on the pin.

Now fortunately, I had just watched “The Marathon Man” the other night, and knew precisely what I needed –

http://movieclips.com/fMhF-marathon-man-movie-is-it-safe/


So with my Dr. Szell dentistry kit at my side, I was able to find a pick strong enough to hold the filling in the tooth while I twisted the collar into place.



Is it safe?  Hey, Safety Fast is the MG motto!



A similar yet somewhat more complex arrangement holds the 1-2 cluster in place, except this time, rather than a single spring and pin arrangement, there are two pins with one spring, a split thrust washer arrangement and an even more preposterous collar arrangement to sort – note the visible pin at 4 o’clock and the tabs on the thrust washers at 2 and 8 – once again, access encumbered by the depth of the cone –



This is the retaining collar, which needs to be put in place over the spring and pins – plural – by pushing in the pins from BEHIND the collar while trying to slide it over the pins in order to turn the collar and lock the whole kitandkaboodle down.



Oh, did I mention it needs to line up with the tabs on the split thrust washer?

Here’s the proof that it can be done, but I have no intention of ever doing it again –



And . . . twist . . .



What you did not see photographic evidence of was placing the springs and balls in the synchro collar and trying to retain them with hose clamps while fighting a plunger on the hub which insisted on being precisely where it made all but impossible that very task.

The end result is that it’s all in place, it turns without grinding, I’m out of beer, and I will never cuss bolts.

Just a quick Question, Is that coagulated blood or grease on the shaft?

[Milwaukee Midget]

Well, let's put it this way - I've been pretty consistent on showing both my achievements and my failures during this build, but as to the nature of the red liquid in the photos, I'd kind of like to maintain a degree of plausible deniability . . .

So yeah, that's grease . . . mostly . . . I think . . .

 

[Geo]

You will note the Renault R5 is the solar version.  The lights heat the air making it less restrictive allowing higher speed. The open roof scoop is for the midships turbo located where a back seat would normally be. Note the engine containment net behind the pilots.

MM you have my highest esteem for your ability to get that trans together.   

I have friends who have a breakers enterprise who can get a Rover engine. It (they) could be shipped with some Jag engines and perhaps some motorcycles to share the freight.

Midget,

Fearless Leader bestows upon you the highest civilian award of the Soviet Union:  Comrad Doktor of Zil Trannys!!   Boris & Natasha recommended you for this honor.

Moose & Squirrel insist on another clandestine debriefing at the same seedy Beerhaven Hotel........   Will advise on date/time........      Squirrel insists you provide both trannys to prevent Moose from hogging one.........

Na Zdorovie,

Thank you, Mr. Know-it-all, but you can tell Rocky and Bullwinkle that I'm on to their tricks, that any further meeting will be in a well lit public place where I'll be keeping my clothes on, and my rear is not some magician's hat from which I conjure rabbits.

Sincerely yours,
