- In this video Jafffa Adventures details how to replace the big end bearing shells in a Toyota Landcruiser 1HD-T diesel motor. These big end bearings have a history of premature failure and in this video Matt, a qualified engine reconditioner, determines if this is the case with this particular Landcruiser 80 Series. This Landcruiser 80 Series has been regularly serviced and has 80,000km on the motor since a complete rebuild.
In addition to the big end bearings, we also replace the timing belt and tensioner, the harmonic balancer, and the remainder of the drive belts.
Of course while doing the work, we also manage to have a lot of fun and laughs.

Very helpful video. HDJ81 w/1-HDT owner here. Thank you for posting.
No worries mate, I trust you will be checking those big ends soon😉👍😎
Great video once again! Wonderful to see the good humour and camaraderie between the fellas!
Thank you mate, really appreciate you taking the time to comment. We get along great and the young lads take the ribbing well. In the end we had a great time together and sorted out would could have been a seriously expensive problem if it failed completely. Keep the shiny side up mate, cheers😎👍
Good one 👍...your big toe would know more about engine repairs than me, but still found it interesting.
Well done on letting the guys use your garage and for Matt to take the lead on the repair. Jacob and his mates seemed genuinely appreciative of the help.
Cheers..
Thanks for watching and commenting mate, that means a lot to me. If you found it interesting and you’re not big on engine repairs, then I guess the video worked as it held your attention for other reasons. That is just awesome. Matt is a legend when it comes to motors, and the young lads are very respectful and appreciative. We had a blast together and that in itself was worth the get together. Keep the shiny side up mate, cheers😎👍
You definitely know how to have fun with a project. Great video !
We do love our shed time, and each other’s company! Thanks for watching and commenting mate, I sincerely appreciate it. Keep the shiny side up, cheers😎👍
Thanks again Terry !! really appreciate your help, video turned out awesome 👍
My pleasure Jacob. You are an intelligent young man with a very bright future, you will do well in life mate. Thanks for the good time and allowing me to hang shit on you. Offence is the best defence they say😂. Keep the shiny side up mate😎👍
1) I used to own a 2006 GXL TD Auto 100 series with a 1HDFTE along with a 2006 79 with a 1HZ. Both purchased new. I liked both vehicles and engines. One towny and one worky.
They were serviced by Toyota every 10k and by me every 5000km. Never burnt any oil and never broke down. Both were sold at 190k. Today my V8 burns oil and makes the sump oil black very quickly. My 2 old Toyota's referred to above always had golden oil. It's not that I mind buying the oil - It's the fact that Toyota diesels are not supposed to burn oil. We've had diesel cruisers in the family since the 70's and they never used oil. These new V8's burn oil, the filter is hard to get to and the starter motor needs replacing all the time because they don't like dust, mud and water.
2) Hey, one technique I use all the time to take off oil filters is a rag and a steel bar/screwdriver. It's simple as. Just wrap the rag around the filter and put in the screw driver and twist. Proceed as nature intended. Easy.
3) People say Go well Go Shell but I say Go First Class or Stay at Home.
I love the 1HDFTE motor, one of Toyota’s best😎👍
@@JafffaAdventures I believe you can still buy complete crate motors from Japan/dealer.
Hope my tips help.

Great video 😃love the banter
That’s good Andrew because we turn that up s notch in subsequent episodes😂. Thanks for watching and commenting mate, I sincerely appreciate it 😎👍
Lovely Vid, I thought that big bolt on the hamoric balancer was one use only, I could be wrong
Thanks Craig, not on the 1HDT was my understanding.
It’s got over 15,000km since the vid, including 5 getting flogged on the PDR in the Cape, still going strong👍😎
Amazing work team 👏 I love it
Thanks mate👍😎
Even the Peewees are excited,
They are indeed mate😎👍
Awesome vid ter 👌🏼
Thanks Cody. I really appreciate you watching and taking the time to comment mate, that means a lot to me. Keep the shiny side up mate😎👍
Getting the sump off? A handful of 1200 mm long hard wood 1" x 1" garden stakes (sharpened to a nice chisel point) can help. Let's you swing a decent hammer at a distance from the sump.
That’s great feedback mate, thanks for sharing. Cheers😎👍
WELL DONE BOYS !! GR8 VID👍
Thanks James, so glad you enjoyed it mate. Jacob's 80 came back from a big trip up the Cape and he slept very well knowing he had new bearings in the beast! Have an amazing weekend mate, cheers!
I wonder if this also happens to the 1HZ. Less pressure, less wear?
No, it does not occur in the 1HZ. You will easily get over half a million km out of the shells on that motor if it’s stock and serviced regularly. Cheers👍😎
Awesome video!
Great watch.
Do the 200's v8 suffer from this also? Interested as they mentions over fueling, all these 200 hundreds with rail chips and tunes, would it not be similar?
Thanks mate, your very kind. The 200’s do not suffer the same fate, even with chips and tunes. I suspect the more modern cars can get the AFR more accurate as the computer controls are more intelligent. That’s just my take on it anyway. Cheers 😎👍
hello mate! killer video. So big end bearing replacement can be done without engine removal? never crossed my mind!!
Sure can Joel, no problems at all. Thanks for watching and commenting mate, I sincerely appreciate it 👍😎
Yikes. I’m 420’000km with no idea! I’ve done 150 of em.
It’s a real issue mate. Cheers
Did you guys replace the cap bolts? Or decided to run them again?
We ran the cap bolts again mate. Modern cars have single use torque to yield bolts but these older cars are not so no dramas using the same bolts over again assuming they are in good nick. Thanks for watching Daniel and good question.😎👍
Hi there I have a question I have A 94 1FZFE engine engine have a small knock Which sounded like it was coming from the lower end just checked all the rod bearings and they all look good wondering if wondering if there was something else I could be checking.
Good question Sterling. I’m no expert but if it is a knock at the bottom end the next thing I would check is your oil pressure. You may need an additional gauge that actually displays the pressure and then compare this against the factory specs. If it’s down on oil pressure I would still be suspicious of the bearings. Just a thought anyway mate. Cheers🤔👍
Great video!
I just picked me up a grandpa spec HDJ80R with 342K KMs. Short motor was installed by Toyota at 243K kms due to bearing failure so looking like this is the next job coming up!
Did they only replace the bearing caps or bearings as well?
Thanks mate, I appreciate the kind words. Bearing caps were not replaced, they typically last the lifetime of the motor. Only the bear shells were replaced as per what has been detailed in the video. Cheers👍😎
@@JafffaAdventures you wouldnt have a part number for that would you?
No mate, any auto parts store or dealer can get you sorted. Cheers😎👍
G'day Terry another great video love watching your work as a fellow 200 series owner i wonder if you could let me know what and where you got your led fog lamps in the bull area I want to get rid of my old 55 watt incandescent lamps can't seem to find any dealers who have supplies. Tom
Thanks for your kind words Tom, I sincerely appreciate it and it means a lot to me. I had another person reach out to me just last week asking the exact same question. I got them off EBay and at the time (about 3 years ago) they were a dime a dozen. There were literally dozens of suppliers and many different variants. Fast forward to now and after search when I had that previous request, there were zero, absolutely none. I was amazed. I can only assume that Covid must have some impact on availability but that’s just a guess. Sorry I could not be of more help Tom. If I do see them pop up I’ll let you know in this comment trail.
Ok Terry thanks for that I will just keep looking. can not wait for your next adventure .
Me either Tom, thanks again for following, it really is humbling☺️😎
Hi there i have a 1hdt and have over 300k on her un opened engine should i do this on her i never get any shavings in my oil
It’s your call but if it was mine I would be doing the job. It’s dead easy and very cheap insurance to keep your car going another 200k. You will not find necessarily find shavings in your oil. They will be very small and any that you can see will be picked up by your oil filter. Cheers 👍😎
Great Northern, Furphy and Crown....Im seeing a pattern here.
If truth be known, there are not too many beers I would kick out of bed😂. Thanks for watching and commenting, I sincerely appreciate it 😎👍
What brand/model is your hoist? Have you had issues with it? Great vids 👍.
Thanks for your kind words Josh, I sincerely appreciate it. The lift has a sticker on it called Direct Lifts. I’m sure they are all out of SE Asia with just different badges on them. Can’t remember what AU supplier I bought it from but they advertised in a Hot Rod or Just Cars magazine. It’s been running faultlessly for 10 years now and can lift 80/100/200 series cruisers with no problems, as well as GQ and GU Patrols. Just in the last month the electrical switch shit itself and I had to replace that, but that’s not a bad run for 10 years of flogging. Thanks for watching Josh😎👍
Got to say I'm pretty shocked with the condition of that last bearing. I wouldn't think that you would get a failure like that within 300,000km of a rebuild let alone sub 100,000km. Surely that has to be some sort of bearing manufacturer issue as Toyota would of had a warranty for longer than 100,000km surely. Would a race bearing like ACL be the best option?? Do you know the origin of the bearings that were pulled out??
Don’t know the origin of the bearing pulled out but I do know this is very common on 1HDT’s. I’ve done several now, same issue. If I owned one I would be replacing them every 100K regardless but this is only based on my experience. Go well mate👍😎
I thought I had read that this wasn’t much of an issue with the 92 or later models? Also how did he know which bearings to get? I was under the impression that you would need to take it apart and verify bearings then order because of there being different ones for different yr models. Just trying to learn, as I’m wanting to do this to my 92. Also great video, second time watching it 👍
Cheers mate. I have not heard of different sized bearings for different year models, that’s a new one on me. It would certainly surprise me if it were true, a 1HDT is a 1HDT. However if your research is telling you otherwise, then fair enough. What we did NOT know at the time was if the bearings in the engine were oversized or not. We took a chance and jagged it. If we would have got the wrong ones a quick exchange at the parts store would have had us sorted. Cheers 👍😎
So I would have thought that if a bearing has delaminated the crank would be damaged in some way or other??
Good question David.
If the delamination is advanced, absolutely. We caught this right at the beginning with only one small fleck that you saw in the video. Also the bearing shell surface material is much softer than the crank journal. That being the case, no damage.
If you take it to extremes, it damages the journal from the underlying shell material, plus typically a drop in oil pressure as the clearances blow out. Cheers😎👍
Any suggestions on brand of bearings to use? Thanks in advance
Just a good quality known brand like ACL, no Chinese stuff. Also, I have confirmed the big end bearing on ALL 1HDT’s are the same, including all 80 and 100 series cruisers. Have fun👍😎
@@JafffaAdventures thanks and i believe what I was confused on was the fact if the motor had been rebuilt then I would likely have a different size. Which you answered in another comment. Thanks for the info
All good mate, go well👍😎
What the measure of Conrad's bearing👍..from Philippines..
036-.054mm
Does 1hz connecting rod bearing also prone to premature failure?
Hi Kamran, good question.
The answer is “no” not at all. Keep your service schedule and you can easily get half a million kilometres out of a 1HZ. They are bullet proof😎👍
@@JafffaAdventures may I add, if it’s fitted with a aftermarket turbo system they do suffer the same accelerated wear
Thanks for the feedback. I had a 1HZ 80 fitted with an aftermarket turbo and owned it for 20 years. At 300,000km I changed the bearings out and they were perfect. While that may certainly be the case, my experience is different. Perhaps the A/F ratios play a part. Thanks again for your feedback 😎👍
Can the main bearing cap bolts be reused??? Toyota say they aren't reusable and should be replaced but they aren't stretch bolts so can't figure why you'd need to change them....
Yes they can, I have reused them on many engines. As you note, they are NOT torque to yield so they do not stretch. Cheers😎👍
@@JafffaAdventures thankyou. Appreciate fast reply
No worries mate👍😎
Sorry mate ,a rookie question. is this same engine as the 1hz ? My 1hz makes a tapping noise while accelerating at high rmp. Could it be the same problem?
No mate, it’s a different motor although they share the same architecture. I have never heard of this problem on a 1HZ, and I mean never. I had a 1HZ 80 Sereis for years and changed the same bearings at 300,000km and they looked brand new. If your vehicle has been serviced regularly, I suspect your issue lies elsewhere. If you are concerned however, as you can see from the video it’s an easy job to swap out. Cheers 😎👍
@@JafffaAdventures thank you sir. One of the mechanic said it’s the valve lifter. Any easy solution for that?
The 1HZ does not have a traditional lifter, but runs shims over buckets. Could be the clearance between the bucket and the can lob. Easy to check with a feeler gauge. Cheers👍😎
@@JafffaAdventures thanks mate. Hopefully you will come up with a video soon about how to check the clearance and the usage of the gauge. Good day sir.
No worries 👍😎
Is it the same for a 1HD?
This is the 1HDT. If you are referring to the 1HZ, the answer is no. Cheers
@@JafffaAdventures thanks!
How do u find out what size bearings you will need ? Thanks sorry for silly question
Hi Billy, great question mate. In our case the owner knew that the engine had been rebuilt and he had the paper work showing that the crank had been ground and oversized bearings used. If your engine has not been opened up, then it will have the stock factory size bearings. If your engine has been rebuilt and you don’t know if the crank has had any work, the only option is to pull the bearings out and have a look on the back sides of the shells. If they are oversized it will have the size stamped on the back sides of the shells. I trust this answers your question Billy👍
@@JafffaAdventures thanks very much that answered my question. I appreciate your time cheers mate
All good Billy, go well mate😎👍
What would you expect to pay to have a shop do this?
No idea mate, I’ve never had a shop do any of my work. I’ll give anything a go. Cheers😎👍
What year model 80 is this?
It’s a 1993 model Lachlan. Cheers
Oil type and spec seems to be the issue and cause. Our Oz oil is the cause the info says.
Interesting, thanks for sharing.
Bottom line, if you own a 1HD-T I would be swapping bearings every 80-100k. Easy to do, cheap insurance. Thanks for watching 😎👍
Hey guys, just got a few questions about the bearing job if youve got the time.
Cheers
Ask away mate!
@@JafffaAdventures Mostly just wondering about how you guys removed and replaced the tops caps? Also do you guys plasti gauge the bearings or just send em in?
Cheers for the time fellas
With the top shells in the con rod, you just push the piston up the bore a couple of inches and you can access them easily. I think we detailed this in the video, but I could be wrong too🤔
Yes we definitely plastigauged the first she’ll we put on. Set in the plastigauge, torqued the cap down with the new bearings, then removed the cap and took the measurement. The first one was good so we took the rest as being ok without using plastigauge. I would not recommend just sending them without taking a least one reading, a mistake here could cost you your motor😬
Good questions mate, thanks for asking 😎👍
Detailed not destroyed, bloody autocorrect 😂
@@JafffaAdventures good ol autocorrect 😅 thanks for the help 👍👍
Awesome video! Is there anyone yourself included that I could pick their brains on a issue with a 1hdfte? Really need someone with a bit of expertise! I'm in qld and have been trying to find someone that does engine reconditioning or the like. Can give phone number if or call anyone you could suggest
Thanks mate
Thanks mate. Sorry but I don’t know the 1HDFTE engines well at all (only that they are a bloody good donk) nor do I know anyone with any expertise on that particular motor. Good luck mate👍😎
@@JafffaAdventures thanks for the reply, a frien offering to sell me his ute.he it might not be 1hd specific it's an engine knock that developed after hole in the radiator got the motor hot. Trying to figure out if the motor needs full rebuild or how to make that call...
A knock is not good in any motor, that’s for sure. If it were me, I would be pulling it down, knocks never get better on their own or just go away. I would need the piece or mind a fresh rebuild give me, but that’s just me. Cheers😎👍
659;000 km on a 1hdt never been apart
Good stuff John, congratulations 😎👍
Its not common at all its false information that carried on because a few 91 models had dodgy big ends in them from factory they can be replaced with good aftermarket big ends and later model 1hdts had a new version of big ends put in them
I’ve had very close experience with three 1HDT’s and all had the same problem, delamination of the big end bearings. For a few dollars and a couple of hours work, I would NEVER take the chance, it’s just not worth it. You and others may disagree, and that’s cool but it’s not for me. Have a great weekend, Cheers😎👍
