1HZ rebuild

[bigbrowndog]

Bottom end - talk to G&S or to Wayne. I bet if you did a quick search here something would pop up. IIRC the southern ones use a softer metal (alum?) that wears much faster, especially if you add a turbo. Bob

I don't understand why people like you come on here and write crap like you have done. So get your facts right before posting rubbish. The ACL bigend bearings [part no, 6B8396std] have no known faults like the original bearings supplied by Toyota. There is also quite a different idle vibration between the indirect injection of the 1Hz and the direct injected 1HDT. And as Rosco pointed out compare the bearing load from the piston on a 1HDT at 10 lb boost and a 1hz at atmosphere at the same revs, lol, perhaps that is why the 1HDT develops a lot more power.
These bearings came out of a 1HDT that has done near 300,000Ks so it seems good oil plays a part also.

So far I have found that all the AU kits do come with head bolts. Cheapest so far is engine australia at 780 AUD.

BlueHZ - do you have any reference info to support your comments on the bearings? Ive not heard that before.

Lynchmob, Realize that cheaper parts usually mean Chinese parts. Some of the parts have less precise tolerances and machining also the hardness of some parts can be very questionable. Generally these parts allow a higher markup for the engine builders but many here still refuse to use them because they will not warranty work with these cheaper parts. They have learned the hard way with failures. The bottom end bolts can be measured for stretch but it is better to replace them as they have been tightened once when the engine was built. Then when you replace the bearing and plastigauge it you use the old bolt, once again tensioned and stretched. Then if the plastigague reads correct after removing it the bolt will again be torqued and stretched for at least the third time.With the new bolt only use it after testing the fit with the plastigauge. Better to use new head bolts for sure as a stretched bolt can cause shimming and further head problems. cheers

Thanks - do you have any recommendations on where I might find a quality kit at a reasonable price? I asked earlier in this thread and havent really had a response yet. Its not something I can get from regular sources here in the US. I havent priced it all out from Toyota, but I imagine it would be considerably more $ than aftermarket.

Thanks

I couldnt even get a price from Toyota,they said its cheaper to buy one of their new 1HZ engines for $9K.
i would be quite happy to use a complete ACL engine kit.
And if it costs a few hundred more than the cheapest unknown brand ,what the heck.

Now is not the time to quibble over $200

 

[roscoFJ73]

Are the HZ and HD Injection pumps basically the same pumps tuned to work with each engine? Could an HZ pump be used on an HD engine if it was tuned up or would it need parts replaced?

They are different but generically the same. I know of a NZ comp HZJ73 using a 1HD T fuel pump on a 1HZ.

Hi RoscoFJ73,


Was offered a 2H with a Turbo kit fiited when new, one owner in a HJ75 1989 with 50,000klm on it original. The HJ75 been kept in a warehouse for 10 years still registered and driven 1 day a month.

Could use the diff centres as spares as well and its a 5 speed manual.

Thinking af buying it for a spare?

Sounds too good to pull apart . The diff centres and gearbox would fit . I think you need to modify the length of the drive shafts to fit i you dobt have a 5 sp in the 40.
But still too nice to wreck IMO

The owner used it as a work vehicle on Stradbroke Is, its not that its rusted its just been pushed and bashed on every panel, mechanically sound but inside & out its a rough diamond, also believe when he first got it he layed it on its roof.

Spending its entire life on beachsand is hard work for the lower powered diesels. Maybe the engines been treated like the body.
But as they say if the price is right......

Could someone please put me on to a good source for an entire ACL kit? In AU or otherwise.

Im not quibbling over $200. The issue is that I dont know where to look for an ACL kit (or who else might have a quality kit).

Do any of the suppliers I listed earlier use ACL? No one really even commented on the quality of the parts that they do supply - other than saying that if they are cheap they must be chinese (and bad). My experience hasnt always been that cheap is bad or even different parts. Some retailers mark things up more than others etc.

Regarding toyota parts.
The gasket kit is $450 US without a head gasket.
Combustion chambers are $115 each.
These are discounted toyota prices... I stopped asking after pricing these items.

Looks to me like they sell ACL components Stateside???
I would use genuine Toyota gaskets. If I was over there I would measure the bolts and see if ARP had bolts to suit the head, bigend and main bearings. Fit genuine or better pistons , try ACl. Hypertec, SRP, etc, try a Google search of parts starting Stateside or get an Aussie mate. I am sure Neil from Roodogs would get you what ever parts you need genuine or non genuine. cheers

thanks bigbrowndog. I have been to that ACL site a bunch - I even downloaded that pdf and didnt see the info for US distributors. Google search kept leading me to ACL australia site and I never found the US site either. And to think - Im a techie... I skipped right to the applications/part numbers when I opened that pdf.

Turns out there is a sales rep in my town. Ill check into it tomorrow .

 

[lynchmob]

Info from engine australia regading parts sources for the 1HZ kit...

"Our bearings are Taiho from Japan, our gasket our manufactured by AA Gasket which is an Australian gasket manufacturing company. Our rings are Japanese, our pistons are Taiwanese, the front cover is Japanese."

lynchmob,

Did you find another source for the combustion chambers and valve shims? Or are you planning to use Toyota?

I have a feeling I will be looking for both at some point.

Frank

 

[lynchmob]

Several sources in AU for $15-$30 each. Ill post up some findings when I get to the point where Im buying the parts.

 

[lynchmob]

kit prices and contents

Here is what I have so far from the sources I listed early on. Prices are AUD.

dieselspares.com.au $870 (company is actually noordeman.com.au)
Pistons - tekein from Japan
Rings - NPR or THR From Japan
Bearing - ACL From Australia or federal mogul From Singapore
Gaskets A.A gaskets/permaseal From Australia
combustion chambers - 17.50 each


enginaustralia.com $740
Pistons - Taiwanese
Rings - Japanese
Bearings - Taiho which is a japanese OEM supplier
Gaskets - AA Australia

Roo Dogs $1495
They resell the basic engine australia kit for this price on ebay though the price seems to vary when Ive seen it listed there.
combustion chambers - 25.73 each


All the above kits include head bolts.
I still havent contacted the local sales outlet for ACL to price out an entire kit.

I think to get an ACL kit you would need to go through Repco.Im not even sure ACL make all the components needed to rebuild an engine

ACL/Repco are a conglomeration of about 30 automotive businesses with Repco being the flagship retailer.
Ive never had a bargain there and drive past the local Repco to get to my favourite store.

Either of those 2 kits would be ok

 

[lynchmob]

ACL does list part numbers for pistons and a gasket set so one would be able to get most of the major components if he really wanted to.
