engine and drivetrain Bang, bang, bang, clunk, shudder, bang, bang, this is not good...

..... what the....

 

 

.... the damn spider gears stuffed. Bollocks. Most unhappy. 

[TobyB]

ah, just weld 'em up. 

 

Differentials are just one- wheel- drive anyway!

 

If you can find a 320 diff, the spiders in those are quite a bit tougher...

Not an uncommon pic. Between the weak spider gears and the weak transmissions,

I made a lot of sparetime money back in the day.

[Nesset127]

Woah.. That's no bueno.

[jgerock]

I have two 3:64 diffs with chewed spider gears.

Hello, whats this...............

 

Jaymic to the rescue;

 

 

Whoa, is that an "S"

 

 

The Lord does indeed move in mysterious ways;

 

 

Okay, order placed for some Castrol Axle Z Limited Slip 90. Unfortunately wont be here for a few days, but this will allow me to ditch the Arse Dragging Spax springs and replace with some OE ones;

 

 

With the Half shafts, and ARB detached and the hand brake off, you can easily fit the OE springs without compressing them;

 

 

Its just a case of setting the lower spring seat correctly so the notch on the underside sits on the dimple on the trailing arm, then threading the spring into place and sitting it lined up on the spring seat, then twisting the top mound to line up with the cut end of the spring and jacking the trailing arm up until you can reattach the shock. Its much easier doing it that writing about it.

 

 

Take the cup off your trolley jack and use a block of 4x2. Keep you jack to the inside to give enough room to slip the shock off and on its lower mounting stud.

Nice write up John!

Whoah!  Nice, concise write-up.

 

Is that a 535i fuel pump under there?

Marshall, thank you.

 

Just noticed that the lower spring seat has twisted a bit!!! But no matter, I anticipate having to cut the springs half a coil to get the ride height (stance) just right.

 

Maurice, its an E28 fuel pump from my collection, but whether its a 520i, 525e or 528i or from an E30, I not sure. There are two different pumps and it depends on whether there is an in tank pump or not. Most European M10 & M20 engined E28s dont have an in tank pump. I need to to remove the surge tank and replace with a fuel filter ah la an E28. The strange thing abount the E28 is, that the filter goes after the pump!!! 

 

 

The pump on this E28 has its rubber cover intact.

 

E28s are just big 02s underneath!

That annotated photo says it all!  Could not be any clearer.  Interesting to see the different set up for the three rubber isolators as well.

 

Thanks for explaining it.

 

Regards, Maurice.

strange thing abount the E28 is, that the filter

Not strange at all, it is the engineering preferred place. Strainers go before the pump.

Was that a coin in the bottom of the housing? Some Copper Oxide trick to improving gear oil life?

Understood that there is a strainer in the tank, but the E28/E30 pump doesnt have a inlet cone filter as the tii pump has. Perhaps I should have said “interestingly” rather than “strangely”.

It does look like a pfennig, but its only the drain plug, disappointingly, otherwise it would be in the Rare Objects thread. Old diff on the right with its drain plug. The new diff on the left, has it on the right side of the casing, not underneath.

 

 

Really gathering a head of steam now, Diff painted and fitted!

 

 

Half shafts and exhaust, refill new diff, then we are good to go.

 

On another note, I really dont like all this black undercoating. Its a really dingy place to wield a spanner under there. On the otherhand it does seem to be very effective as theres little evidence of rust, which is a miracle for a UK car. It spent most of its early life in the fair county of Somerset (where the cider comes from), which may account for this.

Depending upon the material it is and how well stuck to the body it is, you could always prime it and put body colour top coats on. I would be happy with rust free.
