Nervous about oil pressure sender


jjbunn

Recommended Posts

I am adding a VDO 150psi oil pressure gauge, and I have the dual sender (which has an M10x1 tapered thread) and the adapter for this sender, both from Bavarian Auto. The adapter has an M12x1.5 banjo bolt for attaching to the engine and a female M10x1 socket for attaching the sender: it allows the sender to be positioned away from the bulkhead.

By hand, I can screw the sender about 1/4 of the way into the hole on the adapter. I've no experience with tapered threads, and am nervous about the connection - should I be able to screw it in further than that by hand? What is the risk of stripping the threads when I get a wrench on it? How tight should it be?

Thanks!

I think you are ok, thats what tapered threads do if you can give is a couple of turns before it tightens up just give it another half turn with a wrench or so and make sure there are no leaks!! if it seeps go quarter turn at a time!

oil pressure sender unit or the adapter...the sender grounds via those threads, and if you goo 'em up you won't get connectivity. Mine was installed dry around 1988 and hasn't leaked yet...

I would also check that previous owners didn't screw up the threads yet.

I'm no longer affiliated with Maximillian Importing Company in any way, please address any questions directly to them.  -Thanks.

Thanks to all for the advice. Mike, did you use the copper washers on your installation, on the banjo bolt?

    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
