It Runs and Drives

After spending a few days over the last couple of months the Fiat 128 runs and drive - it has headers but no exhaust - the carbs stick but it goes - the video below covers the driving bit - and once I get the start up video (complete with narritive and engine noises I will post that....

enjoy

Wired and plumbing underway

Honestly things have been going on

This last month has seen the wiring completed to the stage where it would appear the engine might actually run - various warning lights illuminate and the fuel pump makes fuel pump sounds..... also the fuel line is in and the clutch line is done.

From This (Fuel cells make great spot to hold all those little connectors)

To This - Deutsch Connectors used throughout

DIY Swtch Panel v1 wiring lay out - v2 is much nicer!

20 A/H Absorbed Glass Matt (AGM) Battery

And stuff working (Neutral Light - Green and low Oil Red)

Clutch Line installed and the starter solinoid at home in a chassis leg bracket

Fuel Line - tank end - this bracket will remain in place when the shroud goes on

Runs through car on drivers side cage members

And ending up under the dash

Throttle pedal and cable also installed and finished

Koso 0 - 13000 RPM stepper motor Tach

Regina O-Ring Chain - 54 Links - 12 tooth front 43 tooth rear  3.58 ratio - geared for 165 kmh at peak tourque and  190 at redline.... a little tall put its what we could squeeze in! have an 11 tooth to try as well for a 3.9 ratio

 





 Wilwood/Whoa 4 Pot brakes (Smart Pads) on Front  2 Pots on Rear (Performance Friction Pads) braided lines to calipers hard line through car - should stop okay I think

I will be aiming for water pipes and headers over the next few weeks.

History Lesson #2 (for those who dont want to hear about the wiring dramas)

Old Stuff FAZA/Filipinetti/Trevilatto 128

its back......!

Okay well here we go - as promised the Tripoid Joints

Blank Cut from 75mm bar  stock 6061 alloy

Machine Toyota GT4 output shafts to suit (shorten oilseal collar and polish and reduce the flange) add three 5/16 bolts and bobs your aunties live in lover

Cool very cool

Next the main bits come together and stay that way!

Old

NEW - extra spacers hold the plates exactly where the need to be no flex and the diff muff is on

Final Assembly with engine mounts

Complete Fiat 128 engine  Kit  with Diff and mounts note unmachined output shaft

Home sweet home

you just sneak down the middle here to adjust the chain tension... yes really

Dummy #3

assembly in car for a test fit.......  yeah baby

Just sitting in there at the mo to make sure it still goes in note cunning use of rack mount as a chain guard

progress that is !

Are we Bored yet????

Okay at the risk of sending my dwindling readership to sleep - especially those who actually like to see pictures of whole complete racing cars - we have been busy FINSHING something - well almost....

So just for the hell of it lets step through April as seen by looking at the same bunch of parts we looked at in February - but now with added stuff - actually mostly removed stuff..  as its machined, bored, drilled, turned, faced and whacked with jolly large hammers....

Pinch ring being drilled to hold the eccentrics which were mentioned ages ago

Thats the drive side bearing hiding  in there - scary and expensive!

Sprocket carrier with bronze bush

Dont kink your neck -  but that is an indexed eccentric bearing carrier - lines every 2 degrees

Eccentric left and right at full "soft" at front of plate

Eccentric adjuster holes 5mm - one every 20 degrees - both sides

No room for bolts on the drive side - countersunk screws instead

Dummy Assembly #2 its almost there

Note clearance chamfer - it now dosent hit the bottom engine mount!

Its all together and being beaten into submission - remember  kids do not try this at home - do it in a shed where nobody can see

Money Shot - note the factory forged half shafts - with the level of planning and design that has gone into this unit there was a moment of stark panic when these were found to fit - perfectly - on both sides of  the diff assembly - as you all know by now this must of course be a mistake and our engineering department is rectifying this as I type,  probably with a large hammer...

But you just wait till you see the tripod housings :-)

And here you can see the spilt retaining rings  - also note the traditional engineering safety footwear and precision chain tension adjuster

WAKE UP! -

I HAVE A DIFF AND I ALMOST KNOW HOW TO USE IT....

just need to make an oil tight cover and do some final adjustments.... then some drive shafts and then you can get back to looking at a race car again...
