1hz

ie. can any 1hz be swapped for any other 1hz? Are there any design differences on the later 1hz's (such as the ones Toyota still makes for 79's in some markets) compared to really early ones like the 1hz in my 80 from the factory in march 1992?

The service information label under my hood is pretty faded and I am having trouble finding legible examples online for a possible reproduction. I am wondering if anyone has a better example under their hood (by the latch) that they can share. Anything would be appreciated, especially an...

Has anyone ever redrilled a 1HZ (275mm) flywheel to accept a 300mm clutch cover? Why would I bother? Because the 275mm flywheels are sorta worthless… and the 300mm flywheels are $700-800.

I used to ask myself the same question 7 or so years ago when the vehicle was at 600 k km's and never could really resolve the issue in my head. According to the people at Berrima Diesel, if the motor does not have any blow-by it's ok to turbo it, but I'm a little hesitant due to the high life...

Just yesterday driving into work.... 700 k km's in 31 years of life since the vehicle was made by Toyota. The t-belt warning light came on as expected to remind me it needs to be done. Is there a contact on the left most number wheel of the odometer that activates the light? I'm aware of the...

Hey, my 105 1hz makes a burr noise when engage to 4H. working fine in 2H. The burr sound is audible in 3rd gear if i drive faster the sound goes away. what does this sound mean? i changed the oils 5months ago,

Serious question time... My 80 is about 350 km off clocking 700 k km's still with original 1hz motor from factory. I know it will need the valve shims done plus the usually 100 k km stuff of replacement t-belt, tensioner, water pump and t-stat to make it viable for the next 100 k km's of life...

Hi all, I just collected Mister Blue, a 2003 105, to daily for a week or two before it goes back in. I parked the truck right after inspection and registration for fear of a timing belt failure. This poor old truck has been out in the UAE sun for a long time and all the rubber has gone bad...

Hey, my friend recently did a rebuild on 1hz 105 because of a cracked head and piston, he said it is common for 1hz, my question is what causes this crack and how can i avoid this for my 1hz 105 that ran around 220Lkm

Just a bit of diesel trivia. I've noticed early Toyota diesel valves will say 'HZ', 'KZ' or 'L' on them which usually indicates engine family. But then I've seen pictures where they're mixed in a given engine. For heck of it, I looked up these part numbers. 2LTE exhaust valve 13715-54040...

Hi all 2008 HZJ71 1HZ LHD , someone know the tie rod lenght ? should be approximately 1184,00 or 1203,00 mm ? thank you Giacomo

For sale new original part #12371-17010 Rear engine mount or Transmission mount (Insulator, Engine) for manual transmission used with 1HZ diesel engine. I bought it for my automatic A440F hoping to work it out, but found an original 12371-17020. So I don't need this one. I paid about $80 and it...

I've had A/C gremlins for a while and when I finally tracked it down a severed wire I thought I had solved it. I did some searching back then and came up dry so I did a little ghetto fix of my own, which lasted me a year or so, but recently gave up the ghost. I would really like to track down...

I'm gonna be home to put a new clutch in the my landcruiser. Found the attached Clutch instructions that may apply and searched the FAQ? What is the step machining required? AISIN specs out +0.5MM step. Do I need to have the machine shop Resurface clutch contact area, and bring down the outer...

In the process of doing my timing belt, ordered all the genuine bits and I noticed there is a change in the backing plate behind the timing belt Tenensioner. The original one had 2 holes that lined up to the dowels on the timing cover and the new one only has one hole. The new one fits but the...

It sits in the back of my mind that when one day I can afford to replace the old nearly 700 k km 1hz in my 80 I'd like another 1hz not a 1hdt and fit a turbo kit myself. But there are plenty of offerings - DTS, HP Diesel, etc. Being a pleb with no turbo diesel experience they all basically look...

Considering buying another 80 to swap the spare '95 1HZ into, need some convincing it's gonna be as simple as I'm imagining... Was planning this for my own build, but the difference with 94 & 95 dash and VX vs DX spec got out of hand, then I got carried away and I'm going with an LS. I need a...

Hey legends, about to convert my 1hz to a 1hdft in my 80 series. Has anyone on here completed the conversion. I'm after a list of what I need to change over in the conversion. I know the sump needs changing and the pulleys? If we can keep this thread strictly for the 80series 1hz to 1hdft...
