2F to 3B conversion advises needed

[MUDHOLIC]

Hello all mech. and Tech. Gurus, i need your advises about an engine swap from 2F to 3B; current engine is a 2F, transmission is a H41 with 19 splines i think as the truck is dated 1984 all stock/factory.
So beside the engine here it is a list of the modifications that i should have to realize:
Belly Housing
Cross member
Engine mounts
and finally input shaft for B engines.
I can deal with the first 3 but the 4 th one is a major problem to me;
as far as i know i can not use an input shaft from a H42 on my H41 tranny + the donnor is a Bj60 86 or 87 not sure of that then the tranny has to be H42; i can not have the whole drive line, wrecker has already sold the transmission as a chunk, all i can have is the engine belly and may be the cross member.
Can you help me out?
how can i connect this engine to my H41 without searching for a H42 tranny?
I appreaciate any advise, idea, help...Thanks

2 more questions:
Does the input shaft from H42 interchangeable with H41's input shaft ?
Can i use the B type input shaft of a H41 with the H42 spec. 3B engine?

Overseas post :whoops:this forum is international, i have seen ppl from all around the world.some of them might have enlightening advises waiting for me
Sure i should have some patience but i have a great deal and before buying the 3B i want to make clear that i can use it w/o changing whole my transmission...
School me on 3B and transmission (donnor is 87 Bj60 H42 and my cruiser is a H41 84 FJ40)
Thanks for your helps and advises

If you find an H41, H42 or H55 for the 3B they all will bolt to the engine. All use the same bellhousing (though there are variations on where the mounts go). Some bellhousings have provisions for a mount and some trannies have provisions for a mount so make sure that at least one has a provision for a mount when selecting one. To keep a split transfer case you'll need a 19 spline output shaft. As far as I know all H55's have a 19 spline output shaft but the H41 and H42 can be either way. Also the internal gears and input shafts of these transmissions are NOT interchangable.

We'll need to know where you are located because Toyota did not equip all vehicles the same way. Any Canadian BJ42 or BJ60 from 1983 onward had an H55, other countries did not.

Thx for your answer, here it is some more details; i am living in Turkey/Istanbul; These cruiser has never been imported by Turkish Toyota dealers; trucks (including the donnor BJ60) has been imported by the Turkish governement for heavy duty purposes like mining, forestry, border security etc. Mine is from costal guard service It has been retired because of the expensive and sparse parts... It end up in my garage...
Vin plate
Model is FJ40LV-KC (no more data)
Trans H41
Engine 2F
Frame: FJ40- 369902
Mid 84 2F engine H41 trans. left hand drive 4 speed (no data about the intended market???)
This truck is all factory i have all the service data and weird but it has drum brakes all around (original axles, no axle swap)+ no ps+ no ac...

The donnor BJ60 had a 4 speed manual transmission as far as the guy parting it out has told me; i guess that it would be a H42 trans.There are no H55F with 4 spd manual trans. as far as i know all of them are 5 spd manual.

I have read that the H41 from 2F and H41 from Bseries engines has different input shafts, B series diesel engines have a longer input shaft,that is why i am trying to find a way out...
If it is possible to use my H41 with bj42 or Bj60 belly and connect the 3B with my old transmission then the problem is solved but i don t think that it is so simple...
Thanks for your advises, plz help me about that swap...the LPG consumption of 2F is opening a deep hole in my wallet,all i want is a decent mileage on diesel as the cruiser is my daily driver...

some informations that i can find on cruiser outfitter webpage:
This has to be my configuration:
34mm Idler - Manual Trans. Setup (H41/H42/H55F)
(8/80' - 4/86')
Input shaft: 19 spline
Input Gear: 34 tooth
Primary Idler: 45 tooth
Secondary Idler: 25 tooth
Hi-Speed Output Gear: 34 tooth
Low-Speed Output Gear: 43 tooth
PTO Gear: 31 tooth
Total Low Range Reduction: (45/34) * (43/25) = 1.3235 * 1.7200 = 2.2764

Donnor is a 87 BJ60:
38mm Idler - Manual Trans. Setup (H41/H42/H55F) & Auto (A440F)
(4/86' - 1/90')
Input shaft: 19 spline
Input Gear: 32 tooth
Primary Idler: 43 tooth
Secondary Idler: 24 tooth
Hi-Speed Output Gear: 32 tooth
Low-Speed Output Gear: 41 tooth
PTO Gear: 31 tooth
Total Low Range Reduction: (43/32) * (41/24) = 1.34375 * 1.7083 = 2.2956

And here it begins the issues:
~83' - 4/86' - 34mm idler shaft. Has oiler provisions. Has spacer bolt hole.

4/86' - 8/87' - 38mm idler shaft. Has oiler provisions. Has spacer bolt hole. Different gear train, bearings and seals from 34mm cases.

+

2F transmission H41 input shaft is shorter than the B series H41 transmission...

I am lost somewhere, or there are some serious issues in this conversion.
(i am not a professional or a guru , just regular guy trying to make his truck DD; so if i am making some terrible mistakes or if i am ignorant about some mech. stuff plz correct me and help me out)
Thanks

Do you have the tranny from the BJ60? If so, use it, it'll be fine.

 

[MUDHOLIC]

Nope it is already sold a long time ago...he has the engine and the belly for sale right now; asking a bargaing price and i dont want loose it...on the other hand i dont want to pay for some engine that won t fit in my truck.
One last question can i use the input shaft from a B series H41 transmission in my 2F H41 transmission keeping my gears; I have seen them on ebay and sor for a couple of times may be that will fix everthing...
Thanks

An input shaft from an H41 will fit an H41 but NOT an H42. If you can find an input shaft then you should be OK.

Ok seems like SOR has them from time to time; i will open a new topic on the "wanted" section but i don t have much expectations, i don t know may be someone had an internal gear issue and will part out a H41 tranny B series i will wait till the right time comes.
Thanks a lot for your helps, now it is much more clear and i have almost had a deal for the engine.Runs smooth and think that this will be a long project after the power steering conversion.
3B will wait its day to come may be for a 6 mo. or more

Just make sure you have the right tranny. Like I said H41 and H42 gears are NOT interchangeable. Most US and Canadian 4 speed trannies are H42. You can confirm it by putting the tranny in first gear and counting how many revolutions the output shaft makes for one revolution of the input shaft. The H42 will be about 4 and the H41 will be about 5.
