the diff in my wagon is leaking from every possible place so i figured i would just find another diff and clean that up and swap them out... less time off the road

Its going to be just as easy and just as time consuming to do up a complete diff compared to puting new seals in the current one. Just pull the axles out and centre out. I didnt even use a gasket on my centre, just blue-poo.

that is true but the car does not have to be off the road to do a second one... plus it is leaking from the front seal, behind yoke, which is a little trickier...

To replace the seal [properly] in a 1200's H145 differential, you need to remove the assembly from the vehicle, then remove the crownwheel & hemisphere from it, then remove the pinion & compressible sleeve. At this point, you discard the sleve & the dud seal. If the yoke is crook, you repair or replace that too.

After confirming that all bearings are serviceable, you re-assemble the diff in the prescribed manner, taking care to correctly set the pinion depth of mesh & the amount of backlash between the ring & pinion, along with the side bearing & pinion bearing preload.

And this is just to replace the seal.
The earlier alloy case H145 from the Datsun 1000 range used a fixed length sleeve [shim adjustable] to control the pinion bearing preload & replacing the seal can be as simple as removing the yoke, with the diff in situ, & replacing the seal &, if necessary, repair or replace the yoke.

The 1200 diff was much quicker & cheaper to build new, but much more complex to service.
I keep telling you that the 1000 was a better design.

i had a sneaking suspiscion this was the case. my worst fears comfermed!!!! finally... you MAY have a point about the 1000 but what happened to the front of the vehicle?? left that to the boys just graduated from tafe!!! ha! ha!

i have a complete diff from a 1200 coupe, no leaks. make an offer.

1200 coupe diff is probably a smidge wider
Unless he actually has a 1200 ...... I don't think he's actually said so yet
If its a 1000 diff your after I might have something

Quote:We have had this discussion before in other threads, so I will try to summarise.

The Double wishbone independent front suspension has been around since at least the mid '30's & quite probably even longer. It is a VERY good & sound design that is still used on some of the vehicles that can be regarded as performance icons today. Jags, Corvettes, Vipers, AC Cobras & their current day [exact] replicas, along with just about every open wheeler race car made in the last 50 years.
There are many more of course, but this will do for now.

The problem with it in a small car whose main selling feature was its low price, is the fact that it needs many parts & is, by comparison, expensive. This reduces the cars competitveness in the low price end of the market where every dollar saved in manufacture is important.

Enter the MacPherson strut. A basicly sound design that was cheap to make, yet provided all of the features that were needed in a new car. It's real attribute for a new car maker, however, was its price. It was cheap.

Cheap, but not necessarily nasty, & its combination of low manufacturing cost & acceptable performance features means that it has grown to be the mainstay of new car front end design & will continue to do so for quite a while yet.

Our small Datsuns abandoned the 1000's front end design for sound & sensible cost reasons, not because it is an inferior design.
So, please do not belittle the double wishbone design of the Datsun 1000, the Corvette, the Viper, the Jaguar, or the F1's, as doing so merely reveals your ignorance.

since you have a 1000 and a wealth of experience with wishbone style suspension... does vehicle weight have any effect on suspension effeciency? comparing the lightness of the 1000 to the more than double weight of the other cars. no hidden agenda just curious!

edit... yes it is a 1200 wagon

i have found a diff in port kennedy. if that is no good i will contact you rally1200
