Re: Aux Fan Bearing Lube

All of the external wiring of the aux fan checked out okay. Fan was drawing under 22 amps. But removing the wire from the underside of the number 17 fuse showed how toasty things got below deck: https://i.ibb.co/VBYR7CP/Melty.jpg I was surprised that both of the red/green wires heading to the Stage ...

Re: 1976 BMW 530i "Eleanor" rebuild project

Nice to hear from you Mike. I suspect the next update will report that the new garage is built, complete with geothermal climate control and a new hand-built two-post lift made from parts sourced from Craigslist, office liquidators and Harbor Freight. Hope you're settling in well.

Re: alternator bushing

I haven't tried this to re-seat the AC belt, but once again citing to the ever-resourceful Lock, he said he used a 1=1/2" C-clamp on the AC pulley to hold the AC belt in the groove to start it, and then rotated the engine to thread it into place. My solutions were far less elegant, relying on a pair...

I didn't know that, as I replaced my water pump at the same time as the flange and the fan/clutch. I'm glad I did now.

Re: viscous fan - how it works + options

Gary - You're probably asking the exact wrong guy, because I'm so OCD about stuff like this, I would remedy it just because it would irk me. As I'm talking to a guy that spent upwards of 10 hours on his back steam cleaning the underside of his E12, we may have something in common in this regard. :D ...

Re: viscous fan - how it works + options

Hi Gary - yes, the water pump pulley bolt pattern is different for the spin-on fan clutch flange. You want the flange (p/n 11511277387) and the matching pulley (p/n 11511271423): https://www.realoem.com/bmw/enUS/showparts?id=3995-USA-04-1981-E12-BMW-528i&diagId=11_3057#11511271423 I got mine from Fa...

Re: No start...looks like no power to fuel pump?

As Robert Bondi pointed out on another thread, the '77 did not have an in-tank lifting pump. This correction posted for posterity.

Re: Aux Fan Bearing Lube

That's a good idea, Mike. I assumed that if the fuse wasn't popping the draw was under the fuse rating. I'm thinking I'll measure at the connector, but I'll need an ammeter with a higher rating than 10A. I have made sure the prong has plenty of tension. I have not taken the fuse box apart to peer in...

Re: Aux Fan Bearing Lube

The approach worked. The fan turns much easier, but my fuse is still heating to around 140 degrees, which is way too hot. I'm going to have to replace the aux fan. Can anyone suggest a good replacement fan and source? Siegal used zip ties and a lightweight aux fan in his AC book, but if there's a re...

Re: No start...looks like no power to fuel pump?

Karl - I learned from Lock that "there are no coincidences" but in this case, if it were me, I'd ignore the gas gauge symptom initially and focus on the pump. I think that trying to find a common cause for both faults brings you back to the ignition switch, and first you should find out if the fuel ...

Re: Fuel Pump wires?

The wires are likely just dirty and not black. The positive terminal on the pump has an M4 nut and takes the green/violet wire (at least on my 1981 car). The ground wire is the usual brown and has an M5 nut. Connecting them backwards will result in the pump running in reverse, but the different size...

Re: E12 interior vinyl colors

Robert, for what it's worth, the BMW "Color and Upholstery Selections" brochure (Rev 2/1980) only lists Beige 0007 as an upholstery color for leatherette. This brochure is for US-spec models. I think leatherette might be an upscale version of the standard vinyl. I've had the same problem trying to l...

Map Lights

Some E30s, E28s and E23s had an interior rear-view mirror with integrated map lights. BMW p/n 51161906525, which is NLA but I picked one up from an E30 part-out. You run power up the A pillar and along the headliner to the mirror, and the base is the same as the E12s. It's more convenient than the s...

Re: 76 530i AT Idle issue?

It's entirely possible to rotate the distributor body while replacing the distributor cap if the mounting bolt is not tightened down firmly. This happened to me when my car was new to me. The presence of carbon on the cap contacts would increase resistance but not affect idle in this way. I would st...
