Alternator bolt in support bracket.

Recommended Posts

I am having a hard time believing that I am at a bit of a loss. In order to remove my alternator I ended up having to remove the alternator with the engine mounting 'bracket' as I couldn't get the bolt out. Well I have heated it and I have pounded on it since I have the assembly off the car but no luck. I don't even understand what it is 'hung up' on. Any suggestions Gents?

Before I buy a used one I found for $35 I thought I would ask. I'm mounting a new alternator so with a new bracket I'd be set, but out $35 beans and its a mechanical defeat!

Best Regards,

Scott

Hal has probably hit on it...IIRC the rubber mounting grommet is held in place with a pair of C-clips; remove the clips and take bolt and grommet out as an assembly.  Then you'll be able to chuck it in a vise for better leverage, and if necessary you can simply cut the offending bolt and replace it with another one. 

 

Also suggest replacing those rubber grommets with urethane ones--the rubber ones turn into black goo in a few years; this'll cause the alternator pulley not to be parallel with the other pulleys, causing accelerated belt wear and eventual failure.

Soak it with penetrating oil  while turning the bolt and then try putting a socket thats several times bigger than the bolt head over the head and use a c clamp to force the bolt into the socket, with the bolt under tension a good wack with a hammer might be in order, once you get it to move it should come out

If everybody in the room is thinking the same thing, then someone is not thinking.

Exactly, the bushings and the metal sleeve are retained by a C-clip.  I think Scott's issue is that he can't even remove the bolt going through the sleeve so he can remove the alternator bracket to access the bushings/sleeve.

Definitely recommend this also.  That black goo is a pain to deal with.

Soak the whole thing (pivot)  in ATF and Acetone at 50% each.

 

It should creep into the space between the sleeve and the bolt.

 

I go against the grain here on the type of bushings as I have had nothing but trouble...over the long term.....with the urethane. They all have disintegrated in chunks on me......If you look in the parts books there are two densities; IIRC you get the 90 Shore bushings. or whatever has the highest number.  Some thought the white Bosch bushings were the thing, but I think they are NLA and the 90 Shore is the same from BMW.

This does work as well as any of the commercial products.  You can also use power steering fluid, close to the same lubricant.

I mix these in a refillable pressurized spray bottle and use it on any seized joint.

It’s a common problem and after many rounds of penetrating oil, heat, clamps and hammers mine still would not budge.  I finally broke out the sawzall and cut the bolt/bushing between the bracket and alternator.  If you go the same route or a new bracket you will need a new bushing like this https://blunttech.com/products/9848299  .  

 

My cut bushing is between the bolt and bracket and shows how tight the bolt fits in the bushing.  It now resides somewhere in the woods an angry throws distance from my garage.

    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
