some of you may know that the diff in my buggy has been stuffed for the last few meetings
so we got it out , gave it back to Freddy & he`s replaced a split cone,
packed/shimmed it all back up nice & tight again (45lbs-ish)

so now it`s back in it`s little cradle & ready to go back into the buggy :-) Yippy :-)

so i thought i`d take a quick snap of it to show you all
Oh & i fitted a brand new 530 X-Link O-ring chain on it now too :-)
i like to spoil my buggy i love her that much :-)

I reckon i`ll be buying a tran-x diff soon tho

anyways,,, next meeting is the day & night autocross at willowbank on Sat the 21st of this month & the very next day 22nd (sunday of course) the Big track Sprint meeting is on
so 2 days in a row of wicked buggy autocross action with my new diff & new chain

cant wait :-)

ok,,, soooo,,,, after 3 diffs shredded now,,, 2 of freddys & one quaife
i`ve decided to rip a few "other" diffs out of stock & have a play

i`m currently in the middle of setting-up a salibury (Plate type) diff

it was looking like i may have had to creat a new (different design) cradle to fit the salisbury in
but i`ve just spent a few hours here at the shop this morning having a good look at things

it`s easier than i first thought,,, no need to change the cradle at all
2x 35mm go-kart axle bearings & their alloy mounts & we`re done,,, i can bolt it all back in after swapping the potty axles out for early splined Hardy spicer type assys :-) :-) :-)

it`s funny as because it looks like the circlip on the inner axle falls neatly & nicely inbetween the 2 go-kart axle bearings,,, the distance is right,,, the small gap between the bearings is just right for the circlip,,, it`s almost like it was meant to be :-)

I`ve bought a larger (44tooth) sprocket & machined it to fit the salisbury, i have our machine shop ready to make a mounting plate to bolt the new sprocket onto the diff
just sort another orange juice tin to cover it all & hold the oil in & we`re away

:-)

choofed i am :-)

i have new alloy front hubs now,,, new 4-pot alloy calipers.

i have new alloy body shocks (twin adjustments) with titanium springs coming

taking the huge alloy 30 litre fuel tank out, replacing it with a small alloy 2litre one, i can do away with piles of weight from all that fuel & extra pump etc.... i`m taking the wings & brackets off the thing,,, i`m cutting big holes everywhere through the space-frame,,, i have Dale (my metal fabricator) making up some chrome-molly rear trailing arms,,, fitting small go-kart discs & alloy Norton bike calipers onto the back of it instead of all the moke arms & cast iron drums & backing plates & shoes & cyls etc etc

i`m ordering some titanium drive flanges foir it soon & maight even fork-out for some titanium axles while i`m at it :-)

i will save (possibly) about 50kgs once it`s all done,,, add to that the zippy-er f/d ratio (Larger rear sprocket) ,,, also the new shock/spring package is half the weight

it`s almost like i`ll be taking one complete front & one complete rear wheel assy off the car in weight, plus removing so much other stuff ,,, 50kgs,,, can you even imagine what a loss of 50kgs will be like in this thing ???

add the sticky new Hoosier-daddy slicks & tighter diff & better dampners & stiffer springs & & &

Like the good ol Colin Chapman from Lotus used to say "If you want to go fast,,, just add less weight"

i heard a story from a few people years ago suggesting that Colin Chapman used to say that-> "design & build a very lightweight, high performance race car,,, designed with the best ideas,,, built with the best & lightest components & material,,,, then once it`s finished,,, take out half the materials" :-)

so, here`s a pick of a few diffs i have here, Pall type,,, & 2x salisbury types, with a few sprockets i`ve been playing with

Image

so,,, once i`ve finished all that change-over stuff,,, diff, shocks, springs, wings, fuel tank, tyres etc etc etc,,, add the new 10"x8" slicks for the hillclimbs & street sprints

& when i go to the big tracks like Lakeside & Morgan Pk etc,,, i`ll just add big 13"x10" slicks tyo get the gearing tall enough for the top-end long straights :-) easy enough to do at the workshop before i go,,, then swap the 10" slicks back on the for the hillclimbs... easy-peasy

i`m sorry for the long winded explanation here, but i`m so happy it`s looking so easy to swap diffs,,, i`ve been pondering this swap-over for a long while now & feared that i`d have to make a new cradle,,, took me ages to get the first cradle right :-) & looks like i can still use it for this new diff so i`m really really stoked :-)

Now i`m REALLY hangin for another fangin :-)

i`m trying for an entry into the Cootha Classic hillclimb in sept, so please cross all your fingers & toes for me cause my first attempt there i was running 2nd outright all day sat & 3rd outright all day sunday,,, & that was running dirt tyres :-)

so now with much lighter weight,,, new shocks,,, new springs... new slicks,,, zippy-er & tighter diff etc,,, i`m just HANGIN FOR A FANGIN :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-)

More news on the diff swap

finally got the whole lot dummy`d up into the cradle, after mucking with spacers & bushes & circlip grooves etc for the support bearings

so were really happy with clearance & sprocket alignment, so all we had to do was make a plate to mount the sprocket to the diff flange,,, got that back from machine shop today (made 2x just in case) & then all we needed was a cover of some sort to keep all that lovely oily stuff inside,,,

The last cover we used on the old diff was an orange juice tin :-)

Image

this time i needed a slightly smaller tin to suit the salisbury diff so after a bit of mucking around looking looking looking for something laying around the shop,,, nothing seemed to be close
so i went to woolys with my vernier calipers to see if i could find maybe a can of coffee or milo or tinned apricots or something, but nothing quite right... I ended up running out of time & had to go out for dinner tonight so i cut my search off early & went & had dinner with Marlys sister & mum, but as i was feeding our puppy (George)
Image

i realised the can of PAL puppy food was pretty close :-)
so i gave him an extra serve to finish the can off,,, gave it a wash out & started cutting her open

how`s this for aR$e--> fits like a glove :-)

Image

Image

Now we have a nicely sealed slippery diff, a zippier sprocket ratio (larger rear sprocket) a cradle that fits sweetly ...& an R1 yamaha powered buggy hanging for it all to be fitted into.

Soooooo,,,, guess what i`ll be doing tomorow :-) yes fitting the whole diff assembly into the buggy, bolting up the axles ,,, cutting the new X-Link Oring chain to the right length ,,, fitting the link & filling her up with go-go juice & goin for a spin :-)

Buggy is Now Zippier & Grippier :-)
cheers people
Matt

I ran the buggy at my dads race track sunday, after a quick visit to willowbank autocross track to help/watch Gaz & Darren Duffields son race

buggy ran great , heaps more grip, heaps more zip,,, very happy, nothing went wrong, nothing broke,,, nothing fell off the car,,, except my arms,,, it`s been a while between fangs in this thing & now with the tighter diff my arms really felt it :-)

time to go back to the gym & start doing weight lifting for my arms :-)

i hope to be back on a race track shortly, so i`ll play around a bit more with a few more things & do a service on the engine & maybe change shocks n springs & wheel-aligne it etc,,, so stay tuned, i`m back on track for some fun :-)

What's your thoughts Matt on the diff breakages? They're supposed to work for a much heavier car I would have thought your buggy being a featherweight would not trouble them.

Maybe the oil can centrifuges the oil away from the cones? Maybe?

Nice one Matt. Are Murray and Josh going to get their car done in time for World Time Attack in October? I sure hope so.
