ontherun987 Posted December 27, 2012 Share Posted December 27, 2012 I ordered an alternator and the ad had two pulleys the one I received only has one. Can I remove the old pulley and bolt it to the new alternator or did they send me the wrong part? thank you for your help 1987 subaru gl ea82 Quote Link to comment Share on other sites More sharing options...

I belive your model will need the two pulleys. should be able to swap them, but I think the single pully ones are lower amperage anyways.. not sure on that though Quote Link to comment Share on other sites More sharing options...
scoobiedubie Posted December 27, 2012 Share Posted December 27, 2012 If the single pulley has the proper alignment, then you can use it. The double pulley is so the alternator can be used on different vehicle models. Quote Link to comment Share on other sites More sharing options...
ontherun987 Posted December 27, 2012 Author Share Posted December 27, 2012 I have a two belts, do I need both? Quote Link to comment Share on other sites More sharing options...
scoobiedubie Posted December 27, 2012 Share Posted December 27, 2012 You need two belts. However, only the front belt goes around the alternator. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted December 28, 2012 Share Posted December 28, 2012 Not true with all setups. If your existing alt has two grooves then you need to swap the pulley and run it with both belts. You can just impact the nut off and swap the pulley - impact the nut back on. GD Quote Link to comment Share on other sites More sharing options...
scoobiedubie Posted December 28, 2012 Share Posted December 28, 2012 I disagree and have looked at hundreds of subaru gls and loyales, and have not seen a single one that required 2 pulleys around the alternator. The primary purpose of the rear belt is to turn the AC pump, but it also turns the power steering. The primary purpose of the front belt is to turn the alternator and the water pump, but it also turns the power steering. The alternator sits so far forward that it is IMPOSSIBLE to connect the rear belt to the alternator. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted December 28, 2012 Share Posted December 28, 2012 You haven't seen all possible belt setups. You can disagree all you like but there are still cases where a dual groove pulley is used to run two belts of the same diameter. Such setups do not have AC. Regardless of how many GL/Loyale's you have seen - I've probably seen more. GD Quote Link to comment Share on other sites More sharing options...
86 Wonder Wedge Posted December 28, 2012 Share Posted December 28, 2012 GD is right... The double pulley setup is used when the alt is between the P/S pump and A/C compressor (Panasonic-made compressor) whereas some EA82s and EA81s had the non-panasonic compressor (name escapes me ATM) where the Alt was mounted outboard (hence the one groove pulley). I'm also finding more of the reman alts that come from Remy (Duralast/Worldwide) as being shipped with NEW double pulleys. From what I've seen, you can use the double groove pulley, just run the belt on the groove closest to the alt body so it will line up with the other belts.

-tombba- Posted December 28, 2012 Share Posted December 28, 2012 (edited) I can confirm that some EA82's have two same lenght belts running in them. I have a EA82T in my wagona nd it does not have AC in it. It has always been running with the two belts on it. Here is a picture of mine when I was fitting TD04 and top mount cooler to it: As you can see there's both belts in there. It's actually a good thing have them both in. If the other one brakes it sill runs normally with the other and you can just replace them later on.

You received a part that can be used in all of the EA82's, even the ones that incredibly don't have air conditioning, perhaps due to local climate (i.e. Finland). You can either leave the double pulley on and use just the rear most pulley to put the fan belt in, or you can remove the double pulley and reinstall your old single pulley.

GeneralDisorder Posted December 28, 2012 Share Posted December 28, 2012 Many DL's and entry level Loyales did not have AC. There are also outboard AC compressor setups as used on turbos, etc that use the twin groove pulley. It's not just in Finland and you show you inexperience with such statements. There are some setups where the single groove MUST be used as the twin groove will interfere with another belt that runs in front of the single groove pulley. There are a LOT of variations.

scoobiedubie Posted December 28, 2012 Share Posted December 28, 2012 General, We are not attempting to solve all subaru fan belts problems in the universe here. We are just attempting to solve one problem. There is a lot of misdirection here, by those attempting to bring in the non-typical setups in order to get this gentleman to put two fan belts on his alternator, when previously he only had one fan belt. Simple problem = simple solution. Quote Link to comment Share on other sites More sharing options...
ontherun987 Posted December 28, 2012 Author Share Posted December 28, 2012 I currently have two belts on my alternator, and order two belts when I got the alternator. I would like to keep the setup the way it is. Quote Link to comment Share on other sites More sharing options...
djellum Posted December 28, 2012 Share Posted December 28, 2012 simple answer is that if you dont need the second belt use the pully that is on it. if you do need it or want it, just switch the pulley for the one on the old alt. belt systems are simple and not universal. just hook it up so that everything spins the way you want it. the more important thing that hasnt been mentioned is to make sure that whatver setup you use is properly in lined up from pulley to pulley. look from the top and if the belt has to go forward or backwards change the setup to make it straight.

Simple problem = simple solution. You just aren't listening. He has two belts and a dual groove pulley now and the new alt came with a single groove pulley. Simple solution is to swap the pulley. Not redesign the belt system to use different length belts. Reading comprehension - get some. GD Quote Link to comment Share on other sites More sharing options...
