HXA433HO - 12Volt 120 Amp High Output Alternator for Land Cruiser HDJ80, HZJ80, HDJ81 / HZJ81 - fits the 1PZ, 1HZ, 1HDT, 1HDFT, 1HDFTE engines.
Suits Land Cruisers from 01/1990 to 11/2006

Alternators are shipped with shipping insurance included in the price of the item in the event of damage.

Kit Contents:
• 12V 120A Denso style alternator with both Active an Inactive options for the charge lamp
• Round/oval adapter plug assembly to connect to early and late wiring harnesses
• 240cm long x 16mm² (6 Ga) alternator to battery cable with a 150A inline fuse

Needed for installation: If you do not already have an upgraded or later version alternator that has the larger case size, you will need to replace the adjusting bar to make this fit. See: "adjusting bar".
On later models, about the 1993 model year, it's a fairly straightforward installation as these came with a larger cased alternator from the factory.

Replaces the following Toyota part numbers:
27060-17020 (12V 60A)
27060-17040 (12V 100A)
27060-17180 (12V 100A 01/1995-03-1995)

Common signs of alternator failure in HDJ80/HDJ81 are:

Weak or dead batteries is the No. 1 cause of early alternator failure!

• Instrument cluster lights coming on when the engine is running - this appears as a "check bulb sequence" that happens when you turn on the key but before you start the engine but happens while the engine is running. This is usually caused by the voltage regulator failing and is usually a "once and done" kind of failure - meaning you won't get any more output voltage.

• Low voltage at the voltmeter after the engine has been running for several minutes and after glow plug post-glow feature has turned off - which can take up to a few minutes. This can be caused by diode failures or the brushes wearing out.

• On JDM HDJ81s that use the 12V-24V starting system: if you are experiencing lower battery voltage at the left hand battery, check the 12V-24V changeover relay. As the contacts inside these relays wear, they may not allow enough current to pass through to the left hand battery. Also, do not tap 12V accessory electrical loads from the left hand battery as your accessories may be supplied with 24v during engine cranking.

• Alternators typically first fail/wear out in the 180,000km - to 220,000km mileage window depending on how and where they were used. If you alternator has been in service for longer than this amount of time/mileage, then you should either physically remove it and have it inspected, have it rebuilt, or replace it with a higher output unit such as the one listed here before it fails in the middle of nowhere.

NB: For use in Japanese Market HDJ81s, use it in the 'active' position for activation the glow circuit and charge lamp

Notes: Ensure your batteries are fully charged and in good condition OR replaced them with new units before hooking up this new alternator.

Make sure your battery terminals and connections are in excellent condition. If your battery terminals are old and not making good contact, replace them with high quality battery terminals.

Ensure your frame and engine block ground points are clean and tight. Check the connections at the 12V-24V change-over relay on the left side just aft of the battery.

Most JDMs arrive in their new home with ancient, low performing batteries still in place - the vast majority of these batteries are junk. We recommend you install two new high quality group 27 (or larger) batteries in their place.

If you kill your new alternator by connecting it incorrectly, or to weak or dead batteries, there will be no warranty (yes, we can tell if you have done this upon inspection!).
