changing diff gears.

[Ed]

Hey guys,

Im interested in changing my diff gears and want to see how hard it is before i embark on this project.

it's a ford 9 inch, i wish to change to 3.5 gears, it has an LSD centre.

my experience with diffs is with banjos only... ie just remove the entire carrier and slot a new one in... or that's the amount of care i gave it...

is this a job for the experts or should any home mechanic be able to perform this task with a little care.

Cheers

Hey Ed,

When I went from the open wheel to LSD, I had to use the same pinion as matched to the centre. I had a guy put mine in... I think the term is blue it in to get the gears to mesh properly... All out of my league is why I had someone do it.

Cheers
Jason.

P.s Is there still a Cairns trip left in that thing.... YOU promised!!!

Hey Jas,

Yep i reckon I will out source it if i do it.

Currently re-wiring my power distribution as it needed some minor improvement, painting things, heater and radiator out.  Has anybody else got a VN commodore with that fusible link box??  mine went into melt down, as a preventive measure I'm changing it to a cluster of circuit breakers.  I think there must have been a loose connection (despite the power feed being bolted to the fusible link).  Fuse didnt blow so I m pretty sure it wasn't drawing too many amps.

A Cairns trip is still on the cards, I need to find the time to do it.  We run our own business so it makes it a little difficult to nail down a time, also the family thinks anything over 15 minutes in the FE is a long drive.  I guess They can fly up and I will meet them there.  ;D

Cheers

ed, the nine inch centre is basically the same set up as the banjo, just alot stronger and dearer but if yor not confident a diff shop can't hert

[Ed]

Ed what diff gears do you run at the moment ?????? ......FC427.......

[Ed]

Mark,

they are supposed to be 3.25 but I'm not sure they really are.

I will jack up the car and turn the wheels and count the rotations to check.

car just seems sluggish and has a high top end.

3.5 or 3.7 would probably wake it up without compromising cruisability. 

Will wait until after the NAts.

Cheers

Hi Ed same as the ones  have 3.25 to 1  for the Hot Rod I have to go to 4.11, because I run a 29.5'' tyre so engine revs will be 2700 at 100kph other wise it will be off cam and as you said a slug ..........FC427..........
