Hey,
I have owned a 1978 fj40 since 1995. Thing came in with a 2 F engine and a 3 speed (non USA version) .
Did a cheap first renovation soon after getting it and drove it around for a few years sat for a few years after blowing the head gasket ' then one day , I decided to fully restore it. I redid the body work , added a Weber, DUI ignition, a header and best of all, upgraded the transmission to an H55F. Looked good. I loved it but in 2010 I got a new Hilux , so the cruiser got parked and got zero attention since.
My eldest son wanted it since it belonged to his grand father . So I gave it to him and a few months ago, I decided to bring it back to its glory days and did a full rebuild . The 2f was low milage since the last rebuild , so I thought it would not be necessary to go thru that expense again, so I started it' let it run a few minutes and left it alone while I redid everything else.
I fabricated front and rear bumpers,repainted both the engine, the h55 and the diffs. We put everything back on, did the electric and went to start the engine...... nothing ! He'll, the darn thing would not even turn over !!!!
We pulled it out of the truck (again) and took it apart. Turns out that it wasn't so well internally and would end up breaking down soon enough down the line..... looked up parts, then I decided to give up on the rebuild idea.
Found a 1hz and decided to the that route.
Before jumping in , I spent hours reading up on performing this swap on this forum and others, analyzed the pros and cons and took the dive.
Let me tell you thT it is an expensive endeavor.
The engine costed me 6500.00 by itself .
Then I read here that I had to find a bell housing suitable for that engine and tranny combo.... got a first one that would not fit the H55. Got the right one with the fork and bearing . The rest is history.
A lot of the info I found online claimed that it was necessary to switch the input shaft from the h55. In my observation so far it is quite an easy swap if you have the right parts .
It became clear to me that the input shaft DID NOT NEED TO BE SWITCHED FROM CORSE SPLINE TO FINE SPLINE.
The pressure plate and disc from the 2f motor are the same size as the 1hz's and fit PERFECTLY
I went thru the trouble of dismantling my danm transmission to switch a shaft that did not need to be swapped.
When I upgraded to the h55f, I used a 3f bellhousing . This would not mount to the 1hz engine but . in my case the rest worked just fine and bolted right up without a fuss.
I had already purchased a brand new Aisin clutch kit , which I had never even succeeded at starting the car with and was relieved to not have to buya new kit for the diesel. Here are some pics.
I can continue posting this write up if it's of any interest to anyone else.
