Car Forum / Volvo Cars / February 2006145 alternator upgrade?
Greetings; I have my '72 145 back from the shop; the head transplant was a success, and now I'm looking into other things. My car came without A/C, and therefore has a 35A alternator. The cars that had A/C installed at the factory were fitted with a 55A alternator, and I'm contemplating upgrading my car to one of those. Does anyone happen to know if there were any issues with doing that? I know the voltage regulators may be different, but replacements are available that handle both the 35A and 55A alternators. Do I need to worry about upgrading the wiring? New fuses? The existing alternator has a bad bearing and and seems to be a bit weak (upon starting the car, the alternator light stays on until I rev the engine, and doesn't seem to be charging at idle); as long as I have to do a remove/reinstall, I might as well improve things a bit. I'll have the bearings in the 35A replaced and keep it as a spare. Thanks, Gary  SignatureGary Heston gheston@hiwaay.net I don't need an iPod, I have an IQ.

It worked... kinda. The biggest problem I had (after dealing with the different size hole for the pivot bolt) was the diameter of the alternator itself. The Ford unit was larger and had to be completely unmounted to get the belt on. I tried a larger belt but then the alternator couldn't be adjusted far enough out to tension the belt - there isn't a lot of swing available. Other than those mechanical problems it was a success.

Does anyone When I had a '73 142, the sorry alternator (French crap) just wouldn't put out enough to handle the load. I got a Bosch 55A alternator and regulator. As I recall, it was quite straightforward to replace the parts. The wiring worked fine and the car ran like a champ. I also replaced the electronic FI with a carburetter and that made a great improvement. While not exactly straightforward, it wasn't all that hard to do. Good luck.

I'll have to check the regulator in there (it's been replaced) to see if it's already a 55A capable version. Looks like it'll go smoothly. > I also >replaced the electronic FI with a carburetter and that made a great >improvement. While not exactly straightforward, it wasn't all that >hard to do. If the pressure sensor in mine dies (again), a carb conversion will be required--Bosch quit making them, and there aren't any new ones left anywhere. Where did you come up with a manifold, and what carb did you use? I may as well start putting the parts together... >Good luck.

Use Megasquirt, SDS or maybe another aftermarket ECU. Good luck with the Alternator. -K I am not really familar with what model number of engine that you have, but not far from here their is a volvo repair shop that on their web site sells a alternator upgrade kit for the B-18&B-20 engines to up grade to a 63 amp delco alternator, comes with a bracket to mount it.The web site is Rainbowautosevice.com. look under parts.

My car has a B20F (D-Jet injection) engine. Nice concept, but $129 for a bracket, bolts, and easy instructions is a bit steep--I can get two 55A aftermarket alternators for less than that, and they will bolt right in. At that price, something like an upgraded voltage regulator or a new cable harness should be included. Thanks for the link, though.

No problem--my lower bolt is a replacement already. The original one broke off. Getting the tip out of the hole was a _real_ pain; had to pull the radiator, drill a hole into the tip, drive an old screwdriver ground to a square point into it to finally crack it loose with Vise-Grips on the screwdriver shaft. Really annoying... At least I have plenty of bolts around. Gary SignatureGary Heston gheston@hiwaay.net I don't need an iPod, I have an IQ.

Bill > Greetings; > [quoted text clipped - 24 lines] > A worthwhile endeavour: > http://www.thebrestcancersite.com/cgi-bin/WebObjects/CTDSites Bosch makes a 55A upgrade that will fit right in to any B18 or B20. Part # is AL77X at KORE-TEK phone # is 508.995.3755. I have no affiliation - there are other suppliers probably. I used this re-manufactured unit on my '70 1800E which is same as your 145 except that you have B20F. Increased amps make lights brighter, able to drive more appliances such as A/C, modern radio and multiple speakers. I have a used amm (air mass meter, air pressure meter, whatever) that may fit your B20F that I pulled from a 140. It worked on my B20E, but I replaced with the correct part # so I have this extra. I believe there are a couple of specialty shops that claim they can rebuild this amm. The ECU almost never fails unless you bake it in a paint shop oven. After that, keeping your injector seals, fuel hoses, fuel filter and fuel pump in good condition are the main things to keep D-Jet working reliably. With FI or carb, consider converting from mechanical points to electronic ignition for improved timing and horsepower.

I found a site listing it as for the '75 240 series. They (www.thevolvosite.com) also listed an external regulator for that year, which would be consistent with the 145. > I used this re-manufactured unit on my '70 >1800E which is same as your 145 except that you have B20F. I think your 1800E is a lot more fun to drive than my 145. :-) Have you looked into the supercharger kit at http://www.v-performance.com/ for your 1800E? The protype knocked six seconds off the 0-60 time for a P1800 / B18 car. > Increased amps >make lights brighter, able to drive more appliances such as A/C, modern >radio and multiple speakers.

Gary SignatureGary Heston gheston@hiwaay.net I don't need an iPod, I have an IQ. A worthwhile endeavour: http://www.thebrestcancersite.com/cgi-bin/WebObjects/CTDSites Gary, I don't know if all '75 240s were configured this way, but I saw a '75 245 wagon with a B20. This was the 1st year of 240-era, so I guess this was a transition year before going to the B230 engine. Because it was a B20 with F injection, it should be able to use the same alternator as B20s on older 120s, 140s, and 1800's. I did not have to change any wiring from the earlier 35A alternator. It was 3 yrs ago that I upgraded to the 55A, so I don't remember if the regulator was integrated or not. In any event, it was plug-and-play. Group, did all '75 240s come with B20, or just some? On the breakerless ignition, I selected the Crane product from IPD. At the time, I read a review that the Perlux product was not as easy to install with "plug-n-play" convenience, so I elected to select the more expensive Crane product. This was on my son's '66 120s. I was happily satisfied, and did not second-guess my selection when it came time to upgrade the 1800E. I'm sure there are plenty of customers who are very satisfied with the less-expensive Perlux product. Bottom line is the same: no more finicky ignition points. On the correctly named Manifold Pressure Control, I'll check the part number on my extra part, and post it to let you verify it is the same part number. Price is $40 plus shipping. That's less than I paid, but I don't think I'll need it in the future since I replaced with correct part # for my 1800E. > >Bosch makes a 55A upgrade that will fit right in to any B18 or B20.
