1HDT BEB after 120,000 km report (1 Viewer)

[sailor]

Just changed out the shells on my HDT after 6 yrs. These were Taiho brand bearings. I use Delo 400 15/40 and Toyota filters exclusively. They look very good- much better than the ones in there when I imported the truck. The little indents on the first one bottom in the row were my fault...

Looks like what i would expect BeB's to look like out of a normal engine so that is saying a lot for a 1hd-t. Nice to see actually i always heard these where 100k kms wear items.

Not really wanting to do this. Just registered mine in CA today. Gotta do the timing belt and install my Bad Boy Turbo!

Nice! I say throw 'em back in for another 120! Just kidding. What does the 1HDT manual say for recommended oil viscosity in our typical west coast climate? Is the 15/40 a little heavier than recommended? If so I wonder if that has made any difference. I know with my wee little 2LTE, the manual says I should be running 10w30, but I run 15w40 also.

15W40 is heavier than what is on the air filter box for these engines (recommended oil weight in jp for these is 10w-30)
The oil analysis tests showed that they were too light and 15w-40 was the ticket at least for my case....

You'll regret it if you put it off. Others before you have.

I run Delo 400 15/40 in anything that is not a 2 stroke Detroit Diesel. In those I run Delo 100 straight 40. (oh- Yamalube in the outboards). Makes for a stress free and uncomplicated choice. Interestingly- there was another HDJ with similar mileage and ACL bearings and they were not anywhere near as fresh.

Glad I am running Taihos in my truck. Thumbs up.

 

[LanceCruiser]

I will see what happens when I do mine again down the road because I got ACL too.

That might be up there .. but I can't imagine that oil in my engine down here .. today was 36C here with 86% humidity .. so hot ..

And here is what the crank looks like. Flawless.

Engine tear down?

How did the main bearings look since they were probably original? Any surprises?

 

[sailor]

Engine shows no noticeable wear anywhere.

 

[ForealBoreal]

why was the engine torn down?

 

[BCR4619]

I heard he wanted to re-piston?

 

[sailor]

Engine tear down?

Yes. I had a sudden increase in blowby and some hesitation on dead cold start. Since this engine has been very cooperative over the years I tore into it and found excess carbon build up in #4 that resulted in a 'trapped' oil control ring. Pulled the pistons and a piece of #4 oil ring land actually fell off. Since all bores mic-ed out perfect and had nice cross hatch we installed all new rings and one new piston. Sent the head out for a valve job as a precaution then could not achieve a satisfactory head gasket seal. Now block is out for a bit of a plane as well. New front/ rear seals, harmonic, water pump, alternator, etc. The dangers of 'while we are in there'... Anyway - to synopsize- with 214K indicated, the engine looks pretty new inside. Injector patterns are all good, breaking within spec.

I intend to take my little guy to the desert soon for his first time and can't afford any issues, hence the extra effort....

ok - be a Deutscher- Douche. Other than #4 piston...
