Hello gents and ladies,

 

I have an LSD centre to put into my E21 diff casing.

The centre will not drop in with the crown wheel attached. the width from bearing to bearing is the same as the open centre that im replacing.

My question is, do the factory LSD casings have more clearance on the sides?

No, the dimensions of the bare open case and bare LSD case are the same. 

 

-Unbolt the top plate of the LSD

-Set case on its side

-Slide in the now-open LSD center section into the case, taking care to not spill the guts.

-Slide in the top plate (and the smaller two internal washers)

-Retorque the top plate down, using the side cover opening for access.

 

then continue with the reassembly/shimming/etc.

I've seen the cases ground down or machined a bit from the factory.
I had to machine 2 of 3 longneck Diffs I built, but I never assembled it in pieces

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
