Oil Pump Chain Part Numbers


2002#3

Recommended Posts

I , too, was a victim of a non-BMW, incorrectly packaged, wide OP chain, in this case, Fibi.  

I have a possible source for a "real" BMW OEM (likely narrow) ---140 chain.  I want to improve my chances of receiving a narrow chain.  

What is/are the difference(s) in these oil pump chains, both of which are shown in all the parts diagrams?  Same length?  Application?  Both same width?

  • 11 41 1 716 989 

Thanks.

  • 2002#3 changed the title to Oil Pump Chain Part Numbers

The one I'm looking at in the box, IWIS part no 50000082 KFZ, made in Germany and BMW part number labeled 11-41-1-716-989 is the real deal continuous chain (no master link).

A radiator shop is a good place to take a leak.

 

I have no idea what I'm doing but I know I'm really good at it.

 I suspect the 140 PN is for the shorter 44 link chain used on early engines equipped with a gear type pump.

MVP is now offering an oil pump chain in the correct configuration

To further muddy the waters, I reused the oil pump chain in my last engine.

It had no discernible wear and as for any possible stretch..thats what shims are for.

I did however install new sprockets top and bottom. Seems thats where most wear occurs.

Is that dirt in pic with the ruler scale or is the sprocket gouged?  I decide which from the pic.

If the sprocket is worn badly, the wear can be seen on the teeth where the roller rubs as the chain leaves the sprocket.

Thanks, Jim.

Yes.  Dirt.  Does not look as if the rollers have caused any wear.  Teeth do not appear to be shorter, or worn in line with the sprocket plane, just beveled in a little from the sides at their tips.  I have seen others worn kinda like this.  Maybe a new chain also is beveled like this, too.  Dunno.  Would a better photo help?

The wear on the sides of the teeth is no big deal, the teeth valleys between the teeth where the work is done looks good.

    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
