3sge / 3sgte / Beams – Slimline Alternator kit

Description

3sge / 3sgte / Beams / 5S – Slimline Alternator kit – To suit the Alternators from the NZ series of engines

The Alternator brackets as used on the S-series are no pretty thing, in addition they are excessively heavy and physically large / cumbersome. The later models as used on the Beams engines were partially improved to be from a die cast aluminium construction but despite the material there are still far from light.

In response to this we have come up with a replacement that suits all longitudinal mounted S-series engines which significantly improve on all of these points. Instead of trying to optimise for the original cumbersome alternator, this kit alternatively uses very common and cheap to source types as originally fitted to most 1 / 2NZFE engines (Yaris / Echo / others).

 

NOTE: Please see the parts compatibility page before purchasing – It will not suit the original Beams Alternator

 

PART UPDATE: The newest batch of the main Alternator brackets have been updated to have a black E-coat finish instead of the previous Silver / Blue Zinc coating.

 

Features and advantages

– Weight: Going from the original 3SGE Beams parts there is a total weight saving of near 4kg. For the earlier cast iron models this is increased to a massive loss that’s close to 6.5Kg!

– Fitment: Both the earlier high and the later low mount brackets hold the alternator quite far outwards, this is made even worse with the bulky dimensions of all S-series alternators. With our kit the outer edge of the replacement alternator ends up being in the region of 50mm closer to the engine block! This gives the engine a much more compact and hence neater look as well as helping those with smaller engine bays.

– Appearance / finish: The kits have been designed to look as nice as possible with a minimalist design. Once installed the main mounting brackets are almost completely hidden. As for the tensioner assembly it’s slim and mounts to the rear of the alternators upper tab for a clean look.

– Wiring: The multi-pin plug as used on the NZ-series Alternators is the elongated oval type- the same as what’s originally used on the 3sge Beams. This lets the wiring connect right up without changes on the Blacktop Beams engines. Also both this plug and the main terminal face towards the engine block. This lends itself to allowing for the wiring to be fairly well hidden.

– Parts availability: This kit suits either of two main NZ series Alternators. So instead of being stuck with something that’s hard to find a replacement / spares for, the NZ engines being found almost everywhere have readily available parts in both genuine and aftermarket.

Parts compatibility – IMPORTANT – CHECK ALL BEFORE BUYING

– Engine / gearbox:  Suits all 3SGE Blacktop Beams engines. As for the other earlier S-series engines this kit will bolt up to the engine block however the engine needs to be both longitudinally mounted (North-South) and use the correct main crank pulley. The main crank pulley needs to be the type with twin equal diameter rows and both to suit a 4 rib belt. Some of the earlier engines use a small diameter 3-rib belt for the inside row and a larger 4-row outer, this crank pulley can’t be used and would need to be swapped. Secondly this kit WILL NOT clear the driveshaft from a traverse gearbox. Therefore it can’t be used with the gearbox from either a front wheel drive, all wheel drive (all-Trac) or the rear traverse layout as used in an MR2.

– Intake manifold brace: This kit HAS NO intake manifold brace provision as used on the Beams engines. With quad throttles this is irrelevant, however if the the original intake manifold is run without any type of brace then it may cause the rubber vibration insulator that it’s connected to possibly experience fatigue over time.

– Multi-pin wiring plug: Elongated oval – same as Beams and later model 4age – compatible plug kits here.

– Redtop Beams: On these engines the alternator pivot mount is integrated with the cooling system, front hook mount and the belt cover sealing. This means that if the engine is converted to a longitudinally mounted (North-South) rear wheel drive format then our kit can be used but the original mount can only be reduced but not fully removed. Also see the other notes above.

 

Parts options

– Engine compatibility: The Blacktop Beams engines require an additional mounting point on the alternator tensioner to suit the dip-stick. Select this option if you have this type of engine.

– Drive belt: The factory fitted multi-rib drive belt is not compatible. By selecting this option a compatible belt will be supplied with the kit. These are from the brand “Endurotec”.

 

Alternator compatibility

This kit is known to work with the two most commonly used alternators on the 1NZFE and 2NZFE engines, these were found in cars such as the Yaris and Echo. It WILL NOT SUIT an Alternator that features a 4-pin square electrical plug / socket.

– Compatible – 70A – Denso / Toyota: 27060-21040

– Compatible – 80A – Denso / Toyota: 27060-21030

– Customer tested – 90A – OEX brand: DXA516 – NOTE: This may require a longer belt (4PK-710) to fit.

– Customer tested – 90A – JAS brand: ANJ279 – NOTE: This may require a longer belt (4PK-710) to fit.

– Untested – 90A – Denso / Toyota: 27060-21020 – This Alternator is likely to also fit but we can’t give a guarantee of it and it may require a longer belt such as a 4PK-715.

– Incompatible – 80A – Denso / Toyota 27060-21130 or 27060-21150 – This model of Alternator requires a different bolt and a nut for the main pivot, it also features a different electrical plug. Otherwise it’s likely to still be able to be fitted. It is however an uncommon model.
