upside down bilstein inserts


BLUNT

Recommended Posts

we need some advice on these. im helping kyle (kweebs) rebuild his suspension and it turns out this car has a bunch of trick bits on it. we cannot get the inserts out of the front struts. we removed the nuts on the bottom of the struts and tried to tap them out after soaking them with penetrating oil. these struts are new to me so im not sure im using the correct method to get them out. there are no threaded gland nuts like youd find on a nornal strut.. i dont want to damage the inserts as we are sending them to be revalved. anyone have any tips on these that has had these before? just bang harder? im worried ill damage the threads. theres a slot on the end of the shaft but i assumed thats to hold them steady when loosening or tightening like normal struts. any help is appreciated

Steve what you have their appears to be a pair of Bilstein "Red Dot" (ALPINA) 36mm dia. front struts, pretty hard to come by anymore and long long ago NLA - so be careful with them. I cant recall for sure, but I believe that the rod (insert) is threaded through the bottom. The part coming through the bottom has a notch, you can either try to use a proper sized screw driver and essentially "unscrew" the insert from the bottom OR try to twist the insert from the top. IF that fails, box them up and send them to Bilstein in San Diego. (Call the Bilstein San Diego number and ask for Jack French in the tech/service department), he knows the old stuff like the back of his hand. You can send them out to them and probably have them re-built and or re-valved if you need/want to for not that much $$$. Good Luck.

I meant to also add that the taper at the bottom is a tell-tale that these are red or green dots (I also think I see a red dot in the paint on the strut). The tube is wider than what fits into the spindle another reason they are inverted (an insert wouldn't fit all the way to the bottom). These also happily had 1.5 deg of negative camber in them if I remember correctly.

I've got those also. Inverted Bilsteins. Very rare. I called Bilstein a year or so ago and they do revalve them. I forgot about the 1.5 neg camber. Sweet struts. I love mine. Using those with stock springs. When I hit rr tracks it's just a thump thump , not a harsh ride at all, but firm. I also have the inverted rears. Rare also

I've got 2 pairs one set is the yellow dot setting (about the same as sports) and a set of red dots that I found new at a garage sale cheap just a couple of miles from my house of all things the reds are the race setting, they also made a green dot that was about the same as HD's but with the 1.5' camber and a much larger piston. Anyway they are very rare so proceed carefully with dissassembley. I would try to loosen the screw after soaking with PB Blaster or what ever you have like it, if that doesn't work I would try putting the strut bearing back on and wrapping the rod with a rag and lightly clamping it in a vice so you are pulling against the strut bearing instead of clamping the rod hard if you get what I'm saying then try tapping down on the strut body around the area where the 3 bolts hold the steering arm are. Let us know how it goes as I would like to get my red dots apart to convert to coil overs.

Don't worry about the world ending today,

Hell it's already tomorrow in Australia.

Guys....thanks so much for the info! I'll be calling the Bilstein dude first thing tomorrow and hopefully i can just send the entire setup out there. Blunt and I have tortured them enough trying to separate them already.

I hope the girlfriend doesn't mind if the struts sleep with us tonight.

This is a progressive, modern home, Father Blunt. Regardless she said the struts were too dirty and that I need to get them powder-coated before she will sleep with them.

What about these exactly makes them "inverted" the rears yes but the front are not.

Inverted means that the piston moves with the wheel, the heavier

cylinder, oil, etc stay with the body, reducing unsprung weight

somewhat...

A regular Bils front insert's actually inverted, too- the big 'tube' you see

coming out the top is actually the cylinder, and the piston's attached to the bottom

of the insert tube...

that's why they can fill up with water.

    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
