H55F + 2H Clutch

[Tapage]

Just to confirm .. 21 splines on the input shaft for the H55F right .. ?

It's time for a new clutch in Tencha .. I will put an Aisin factory 275mm on it .. ( last was 8 year of really good service anycase .. )

Also got the CT52A1 push rod bearing Koyo .. and the pilot bearing 6201-ZZ in Nachi ..

Tapage,

I'm about to put an H55F in my HJ47. The input shaft on it is the coarse type - 10 splines.



I'm pretty sure the fine spline input shafts are for a different engine type - 3B perhaps?

was figuring the same thing searching in Autralia .. where the HJ60 are more popular .. all H55F are 10 coarse splines ?

Yep ,same as the 3F

Yep ,same as the 3F

thanks .. again ..

anychance confirming the bearing numbers . ?

There is a thread on here somewhere on which I'm pretty sure I read that some of the H55F input shafts have fine splines while others have coarse splines depending on year of fab.

Will a 2H fit a fine or coarse spline?

Everythings the same(year for year) except the input shaft,Bigbrowndog did a big write up some time back

2H has a coarse spline
Its the amount of splines that dictate whether it is fine or coarse because the shaft is the same diameter
This a 1HZ 21 spline input shaft. Its fine because it has almost twice as many splines

the 3B that comes mathet with an H55F tranny it's 10 slines too .. ?

1HZ with H150 it's 21 splines fact.

1HZ with H55F .. ?

1HD-T with H151 it's 14 coars splines fact.

Hi,
the 3B has the fine splines (21), the 2H the coarse ones (10_. 2H input is the same as 2F input (10).

1HZ has the same as 1HD-T, none of these match the 2H or 3B.

cheers,
Jan

ps: rick beat me...cheers

Nop .. the 1HZ and 1HD-T are diferents .. 21 vs 14 splines .. actually are not engine related, it's tranny related the H150 vs H151

 

[roscoFJ73]

Whats the 1HZ R151f got ,anyone, to complete the list?

Actually the 1HZ engine never come ( as far as I know ) mathed with H151 ..

thought it could be posible use it with a proper flywheel surface ( 300mm) the 300mm PP and 14 splines 300mm disc ( 1HD-T combo ).

What I need to do in my tranny swap to use the H150 in my 1HD-T involve an Isuzu clutch disc that's 300mm but 21 splines ..

I did say R151f, not H151

Beanz2 did a write up on the Isuzu clutch mod but it might have been to use a H55F with a 300mm flywheel on a 1HD T

cool, thanks. I could have sworn I saw 14 spline on a 1HZ, but I don't know what tranny that was. I thought H55F, as in your original question.
cheers,
J

upps sorry reading to fast .. ( without glasses )

I'm thinking the H55F 21 spline clutch are for those H55F behind the 1HZ engine ..

And yes the 1FZ-FE engine use the 14 coarse spline input with the H151 tranny .. 300mm clutch ..

David,

My 2H is an 8/81, with a 2 year-old H55F. 10 spline.
Call John at Radd in Vancouver to verify the bearing numbers, he's the biggest 2H geek I have talked to.
