Happy New Year.............in the machine-shop cheers


Hi,

Yeah, well, that is inevitable when you race an "orphan" engine, never imported to your continent . . . . .

The only good news is that I have access to a vertical mill and a lathe, and know how to use both.

 cheers   and Happy New Year (frozen version)

As my buddy Fred Gorke is fond of saying "it's merely a bolt on accessory"



Well, doesn't it have to bolt on first?

In both of the examples here, the mounting bolts (studs, whatever) would not pass through their corresponding mounting holes.    Not exactly what I would term "precision".

If the manufacturer had stated that the part would need to be "fitted for precision alignment to your component", OK then, I would expect to have to perform some "fitting".

I think that it is a bit misleading to advertise a "precision lazer cut part", when in fact: It doesn't fit.    This is probably just my anal retentive engineering nature here, BUT, it has to be one, or the other, in this instance.


This is a common complaint from those who buy low production, specialty parts.

A/  Not as much of a problem for me, as I have tools, machinery, welders, etc, and the ability to use them;
2/  More of a problem for Chris, as he has less tools, etc, and therefore less experience with them;
d/  It is a serious problem for the enthusiast with a kit of wrenches and screwdrivers, and little to no experience.

I also realize that this is exactly the situation where we all learned how to "Hot Rod" and modify parts.   Keep in mind, though, that this is not the case with everybody.    We all know guys like the proverbial Jack Yates, Jr.   His modifications and fabrications don't turn out so well . . . . . .

midget,

OK, spent some time disassembling the starter solenoid to investigate moving the B+ post to the alternate location.    It will need the alternate copper contact (different shape) but I suspect that can be found in a Hitachi starter core, or purchased new from a starter rebuilding co.

Anyway, revised placement of the B+ post really simplifies mounting tucked in close to the block.   It looks promising on offer up, compared to the original configuration.    I think we can just revise the angular location CCW to the max height allowed by the starter cutout in the bellhousing, then rotate the starter on the pinion axis to provide maximum clearance the the K cylinder block and the engine compartment/frame (unibody) rail.

We will still need to "neuter" a couple of mounting bosses of the RH lower side of the block, but the whole operation looks easily achievable.    My die grinder and Aluminum "hogging bit" will travel to T & T next year . . . .

 cheers

OK, here are the photos to go along with the starter issue:


Showing the 2 positions for the B+ post attachment



Closeup shot with the solenoid plunger removed.   Better visual of the 60 degree mounting differential.



Starting the re-positioning process


With the B+ terminal in the new position, the starter assembly can be mounted closer to the crank centerline, on the original pitch center diameter, ensuring proper engagement of the starter gear teeth with the flywheel ring gear teeth.

 cheers

Thanks for getting these posted up.

I resolved this morning to open a Flickr account, which I just did.  I'll be able to start posting up photos as to the happenings in the Pommy Pigmy Playhouse.

I may go back through the diary and repost some photos that the jackasses at Photofuckit pulled, but it would be weeks trying to recreate the entire thing.

Happy New Year!

I not sure Flickr is an easier to use Vs Fbucket, but my stuff sure loads faster and sorts easier.   Anyway, I'm not paying P/B the "ransom".

But, I have decided to leave my P/B account alone and dormant.   Sometimes my photos appear here, and on other sites.  If I delete the account then that stuff goes away.   If P/B wants to delete my material, well, I can't do much about that, but I'm not going to willingly delete them.   I will however, duplicate all my material on P/B on Flickr, sort of as a online backup system.

I'll put more photos, etc, up as I go through the process.

Some photos of the K belt drive:








The big issues are going to be:

A/   Reducing the speed of the water pump, which is currently a 'slight' overdrive.   Pulley diameters large enough for meaningful speed reduction approach cam drive cog diameter . . . . . ;
2/   Incorporating a solid, fixed belt tension adjustment;
d/   Accomplishing both while using a readily available, kevlar reinforced, MTD style drive belt.    Preferably stock length, but ? ? ?

One solution might be to gut the stock water pump, making it into another idler for the timing belt, and using a thermostatically controlled electric water pump, ala BMW.   Creating yet another reason to fit an alternator . . . which is crossing over from "likely" to "mandatory".    The ability of an "unsophisticated" battery powered system to "reliably" power ESC & EFI seems less than prudent, even before adding the additional load of an electric water pump.

We will have to tilt our heads on 1/3/2018 and see if anything clever spills out . . . . .

I hear you Jack.    My eyes aren't what they used to be either.    And I've been wearing specs since I was 6 years old and REALLY looked like Egghead Jr.! ! ! !


Somehow, I thought ageing would be "better" than what it really is.

I can only conclude that I willfully disregarded ALL the obvious signs that were around me:

A/   How my grandparents aged . . . . . .
2/   How my parents aged . . . . . .
d/   And how my brothers chose to live, and the price they paid for their "indulgences" . . . . . .

Ah well, you can only play the hand that you are dealt . . . . . .

As per the stainless steel thread galling, use of dissimilar types of stainless steel for the male and female parts seems to be working for me.  The same thing is done for titanium fasteners for the same reason.  In that case I use structural Ti for the bolt and stainless steel for the nut.

I've got an e-mail in to Don on the water pump - attachment to the spigot on the back of the pump is my chief concern at the moment.
