Done loads of these on the side of the road no problem with a good jack.

Good jack and good technique, Anton, i'll bet.

Yeah it was only the first time I tried without a jack. Never again.

off to Antons or saturday for some exhaust surgery

but in the mean time have been visiting a chap called Geoff

gave him

Borgy warnery M78 housing from a valiant
Torqueline Torquelock for a VL Holden commodore
a big box o shims
a bigger box of bearings
Ring and pinion from a 92 firebird
a bag o bolts
a crush sleave eliminator from a ford 8 inch something or other
valiant wheel bearings
moser axles.

and said make work, please

he said the end of your pinion is too fat, i'll need to cut a bit off

once i'd workd out it didn't involve physical violence i said yes.

and last night i collected the fruits of his labour

and much to my relief my reaserch into what i could stick in it paid off

you can build a nice thing from bits of everybody elses axle

notice the white cover....so i can prentend to be a military landrover.

hey and when you turn the pinion...both wheels turn the same way
and they should all the time unless one of them comes off the ground

Very smart David

is he an axle guy Dave? I'm needing some new gears in my Ford 8"

Dave , that looks like my Dana, is it a "made under licence" jobby ?

oh yes


rear ends a speciality according to his adverts

geoff hauser

i had plans to build it myself but with engine stuff taking up my time and such a mishmash of parts AND the fact that the mock up showed that the fat barrel of a centre i wanted fitted collided with the flat end of the pinion i spotted that i'd over stretched in my ideas and gone way beyond in expections of my own patients and ability

hence the only man i knew would have all of the sundries to hand to cover off anything i had missed got the job.

6-7 hours labour + 1 breather and job done

pleanty of places can put in the gears for you, couple of candidates on here. Just mine appeared to have the potential to be a Pig of a job and possibly need parts that most would have to get from america so i let Geof enjoy that challenge.

as it turns out wsn't a challenge geoff said "that was not too bad" and he didn't need to get anything in. and his labour cost is pretty bloody reasonable

Borgwarner Australia...made them from mid 60s in a range of models where the name dictated the size of the ring gear. M60 6 inch M75 7.5 inch M78 7.8 inch or 7 3/4 they did M88 and M90 as well


they did beam axles IRS centres in open, cone based LSD and now do Hydratrac (TVR dodge Viper etc)

opend factories in indonesia south africa and kept base in australia

company split in to tranmission and axle sections trans section became part of the whoile T5 T56 Tremec thingy

the axle section became BTR engineering

then Spicer Axle Australia part of Dana

their products used in

ford holden Chrylser australia

GM US cars carmaro Firebird and later Monaro/Pontiac US police cars

TVRs

Morgans

Lotus carlton
Nissans
toyotas
southafrican military jeeps.


so if a car Was made in australia there will be a borgwarner M axle for it

escorts and cortinas got a 7.5 inch LSD that is way stronger than the english and atlas axles

viva got similar as the Torana

mines a 7.8 inch Borg warner M78 that was good for 280 Ftlb with 25 spline axles and a cone based sure grip

should be a bit better now with the 28 spline fatter axles and a centre similar to a truetrack


Dana UK no help at all with parts. they didn't even know what the axle was



Dave

Very good Dave . I thought it might have been someone a bit more local.

car went to novatech in slough last friday for some rolling road set up of the carbs.

I had it running no. smoke, all good for once, but it popped and farted. previous week I'd put seals on the exhaust valves.

aim was to make sure it was running properly for that nats.

stuck at the lights in slough it nearly gassed me. Smoke back with a vengeance. None on the way!!!! but I'd booked the Rolling road time so in it went

too small on the idle jets was causing problem at 3000 rpm

that fixed and it all balanced it came up with 240 BHP graph still going up when he jacked it in at 5200

VERY much not what I'd hoped for.

however drives lovely and comes on cam at 2500 like its been kicked up the ass

consensus was needs a re-curve on the dizzy and needs the oil control issues sorted, both hugely detrimental, can't run proper advance due to oil
advance at low rpm is too small curve is too long
Oil is playing havoc with ring seal and fouling plugs

but at least my carbs are now as right as they can be given the issues

decent lambda reading across the rpm range.

aim was to pick it up Saturday and get it MOTed

had to go to Essex and get back in time

and as I found out yesterday I got caught doing 100 MPH on the M25 trying to get back (potential ban, max fine £2500 automatic court case)

I was an idiot yes but so were the people doing 60 in the outside lane with people undertaking. (I didn't I just blew by when they eventually pulled in and suffered for it)

anyway missed picking it up and MOT

picked up on Monday morning and drove to work smoke is terrible
rolling road say stem seals, do them again and hope

fedexed a new set from felpro

fitted wed/Thursday

took it out for a spin

Smoke. less smoke but smoke

then on the M3 back into London last night

oil pressure dropped. low revs good to exceptional higher the RPM the worse it got cruised into garage at very low rpm.

turns out I've used 3/4 of a litre in less than 100 miles

25 quid on oil and got it home


so No car at NATS
possible No me at NATS if I get banned

I have a serious oil control issue.....

and its Rings again.. before Roger pops up and says they are in upside down they are not, they have dots on, its obvious which way they go...

I'll pull it out tomorrow

order a new gasket set, new inlet gaskets, new rings, new main seal, and try again.

20 thou over pistons take 20 thou over rings... YES Yes they do...they do.

pistons and rings by same manufacturer. side play in ring grooves was to spec

bore size checked with T shaped gauge and a decent 1970s ex engineering shop micrometer that I checked on a gauge block (always greased cleaned for use and re greased. not rusty, always cross ref with crap electronic vernier

if need be ill break out the bore gauge used originally again.

It obvious that no. 3 is a huge contributor to the smoke
its obvious that all 6 have oiling issue.

unknowns.
Has my abortive attempt to tune carbs, again washed bores
has my new sump with solid baffle caused oil flow back issue and huge windage.
have I cooked the rings running too lean too rich or too hot for too long. hence no ring pressure from the oil/expander??

its just a mess, its obvious that I have now fixed the wrong problem twice or have failed to fix the actual problem due to too many unknowns...Embarrassing annoying frustrating fed up


On top of that builders in/no kitchen/ no dining/ no living room, living in spare room with microwave, mum getting ready for chemo-therapy and father in law recovering from heart attack

work is Bananarama!

You know what

I'm going to the pub.....I may be some time

Dave

Sorry to hear all that Dave, must be so frustrating.

Have you checked each bore for size in several places?

So sorry to hear of all your woes after all your efforts.

Fingers crossed on all counts; really hope you make it to the Nats and good people will help you drown your sorrows a bit....

Take it out take to a good engine builders shop have them sort it, so whjat it was not you your life can move foreward and You get to enjoy your car at last ,,,,
