High Feature V6 Swap

[The Dark Side of Will]

Making progress! Great find on the alternator bracket! To summarize, you just used the alternator that came with the engine, but mounted it on the Camaro LFX bracket?

Found the stack height of the Saab F40 clutch/pp/fw combo... 3.15" not a lot of room to work with for a twin disc setup.

A 282 has 2.425"

Resplined LNF Axles are in and will be assembling them this weekend.

Who'd you have do that work?

Sorry, let me clarify...the XTS LF3 did 'not' come with an alternator from the yard which mounts on the firewall side of the engine in the fiero just below the top of the head, above the compressor, and is specific to the XTS being the only transverse mounted 230amp alternator. So its.. ATS-V Alternator --> Camaro LFX Alt Bracket --> LF3 trunk side block.

Hudlow Axle did the resplining... not sure if they'll hold as there's a small but noticeable amount of play when the inner race is slipped on the new splines... if they shear I'll go with the DSS LSJ Axles and have them upgrade their 400hp Stage 1's...

Resplined LNF axles to fit G6 inner race:


One of the boots from the LNF was un-salvagable and due to the large shaft size I ordered up a flexx boot from Astoria2000.net. They are very high quality and the rubber is OEM-like.


Everything ready to go back together (Fiero outboard stubs, Pontiac G6 inner and outer race and balls, Resplined LNF shaft, tri-lobe, and inboard stub:


FYI, Redline CV joint grease is the exact same color as the 'good' slime from Ghostbusters II.

I'll skip the assembly and in my best dead-pan voice....

taaa daaa.....



hmmm... just noticed....missing a dust cover for one of the fiero outboards....

Camaro LFX Alternator bracket on LF3:




V8 Roadsters PS Pump delete pulley/idler:


Flipped intercooler 180deg to make more room for turbo cross over piping, will be going with weaponX inlet/outlet fittings instead of the stock outlet which would point 'right' into PS shock tower. Also, that's the LF4 ATS-V manual transmission wiring harness 98% plugged into the LF3.

What's the over/under on how long it takes you to pop a Fiero outer?

haha!! Shear the new splines, snap the stub, or crack the outer race?

[The Dark Side of Will]

Just wring the splines right off the end of the outer body.

Yeah.. they look pretty sketch... I'm already going to call DSS and see if they can upgrade their stage 2's above 400hp... that rear fiero upright/hub-bearing is a real limiting factor when it comes to outer stubs....

still waiting on that 88 rear upright cad design....

[The Dark Side of Will]

You and me both

I have some hand measurements, but have been thinking that I just need to get an early and a late knuckle over to the CMM guy to get better numbers.

[Shaun41178(2)]

Dont dump the clutch and the fiero outers will hold just fine..

I put 460 lb ft of tq to the tires and mine have held up. So far

[draven]

I think we're both referring to the less than stellar resplining job on the axle outers...

[The Dark Side of Will]

*I* was referring to the Fiero outer CV joints... although the axle re-splining job may be suspect as well if the shafts were not case hardened following the respline work.

[draven]

I've still got the DSS Stage2+ and GatorRacing Axles if these go tango uniform on me...

round 2, 0.25" thickness, and added radius to the tooth root.

ericjon262,

When you can, please shoot me over the final drawing specs for th 30 tooth wheel with a 45mm diameter. I "thought" I found a company on line Vksfab that offered custom tone rings for 100$/pair... sent him my specs 2+ weeks ago and 'nothing' and blows me off every time I call for an update (didn't pay up front this time)...… sheeesh….


If possible could you increase the width of the gear from 5mm up to 10mm instead... that'll give me a little width to play with when I build the custom sensor mount.

If anyone is interested in one or more of these VSS rings for the saab halfshaft diameter, let me know and I'll tell the machine shop to adjust the quote accordingly.

[ericjon262]

I can send the file, but I don't think you ever sent me the exact dimensions you wanted, or the exact tooth count. it will probably be Thursday afternoon before I can send the drawing, PM me your email so I can send it as an attachment.

Let's go with 30 teeth, 45mm ID, 10mm width.

Maybe a 5mm tooth depth...

Let's start with that , throw me a few renders if you would and we can see if those dimensions work... sound like a plan...

Just PM'd you my email..

If it's an interference fit, you'll need more digits on your ID number than that

That's where I'll have to defer to you gentlemen. What would be the appropriate ID for an A36 or equivalent ring for a heat/shrink slip fit?

I assume that I could lay a couple of small tacks on the ring to axle to secure it if necessary...

Update:
Broke out my introduction to mechanical from college (CompSci majors had to take several intro courses to other engineering disciplines as all we do is really apply our skills to other engineering or business disciplines)

Maybe an FN3 Shrink/Press Fit Tolerance
So 45mm is 1.7717 and with a FN3 1 thousandths hole diameter tolerance ID of 1.7717 max ID and min ID of 1.7707

Sound fair?

[The Dark Side of Will]

Put a micrometer on the axle and take multiple diametral measurements at different angles where the you want the ring to install. I doubt it's 45.00mm or 1.7716". I also doubt it's very round.

If you're willing to tack it in place, then a 0.001-0.005 clearance fit would be much easier to manufacture

good idea... I'll do that tonight after I take some of the oem paint off the axle.
