Post subject: | got my diff fixed |
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 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 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) 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 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. M |
