Wanted: 60s FJ45 trans hump

[Living in the Past]

Thanks for the info. I have studied that thread extensively actually...the "save a virgin" one. I will be going with a new H55f. I now have an original LPB hump, a few mid 70s fj40 humps and a parts fj60 to use as well. I guess I will find out exactly what I need to do when I set the cab back on the frame. The 70s fj40 humps might work but the floor coverage footprint is so much bigger than the original hump that I am concerned it will just be a good place for water and mud to collect and start causing problems.

Since my 45 no longer has the original engine I plan on switching the cowl from a 78 FJ40 and update the 45 to around that date with the front clip, doors and windshield. The cowl I plan on using has most of the rockers and floor back to the B pillar. Thinking of grafting in the floor around the tranny hump to avoid the space to collect dirt and possibly rust.

WOW!...funny you mention as I have been contemplating exactly the same thing. Was thinking about using my parts 1976 fj40 cowl, doors, windshield frame etc. I was thinking of doing it at the seam at the front where the floor starts to go up. I did contemplate what you are proposing but wasn't sure it would be very easy to graft it towards the rear of the lpb cab. Seems it would be ideal to include the floor of the FJ40 tub as far back as possible including the gas tank bump, under the seat and all the area of the trans hump. Any idea if there is a seam there that would be easily used? Guess I should look...just assumed it would be a PITA. non-rusty 1965 lpb cabs aren't exactly easy to find...gets a little scary thinking about cutting mine up.

Wasn't planning the whole floor and rockers just a couple of inches around the transmission hump opening. I have also though of using my 82 tub I have and trying to go back to the B pillar and use the later tank but think that would opening a can of worms. Doubt the 79+ seat would clear the back of the cab. Custom fill neck and who know what else. I am think of using the top of B pillar so the later door latch will bolt on.

Sounds like a plan. I just looked at the floor of my cab. Seems a few inches around the hump opening would work. How do you plan to deal with the interface between the top of the windshield frame to the roof? I guess transplanting the latches onto the later windshield frame might do the trick.

Plan on using the latched but a little more than just simply adding catches to the top of the windshield. Going to installing the floating plates so it's adjustable. Biggest problem might the hosefor the windshield washer.

For What it is worth guys I put an H55 in my 76' FJ40 ( I understand there is a difference between 40 and 45 humps, but I'm not sure what it is). I used an FJ60 (87') tunnel cover over the expanded hole in my original hump. It took some work but I'm satisfied with the result. I had some control over how high the transmission stuck up through the floor board as I did not set my frame brackets until I saw where the top of the transmission was. BTW Adam your package will go out in Wednesday's mail.

That looks good Mike. Another option I guess. I have a parts 86 fj60 so with all three I should be able to come up with something. I haven't mounted the trans/transfer yet so that is slightly adjustable still. Thanks for the package update.

Does your H55F have a 60 series top plate? How does it shift with the shifter that far back. I was checking out how the 60 series shifter and boots fit in my 68 FJ40 with four speed and 75/76 tunnel cover installed. I would want to bend the shifter up and toward the center a little. My biggest reason for not buying a H55F is the shifter location. Not sure what gear is was when I took these pictures. I know it wasn't reverse and may have been 1st gear.

FJ40, H55F/Split Case, 1st gear lever position, modified stock hump, switched to FJ60 parking brake lever (because I have a late FJ40 rear axle with parking brake mechanism).

My transmission was ordered from Toyota to fit an HJ60. Shifting is trouble free. There is almost no difference between the H55 and the original H41. In my picture the tranny is in 2nd gear (1st is straight up from there), the knob barely touches the seat coushion. All other gears are a clean miss on the seat.

 

[Living in the Past]

From what I understand the gearing on all H55Fs is the same. Two versions of input shafts. BJ and FJ/HJ. Two top covers. 4X series and 6X/7X series. I know the FJ/HJ input shaft with a 6X/7X series top cover is still available new. Not sure if the BJ input shaft style is still available but I know the top for the 4X series not. Won't mind using a H55F in my FJ45 but besides being anal about having the shifter in the right location I plan on using a hybrid bench seat and need it further forward. I know I can use the shifter from any H42/H41 transmission with any other, even if it has a difference rear spline for the different transfer cases. Will this shifter work on the H55F? If so the FJ40shifter would be a good option to use in a 4X series with a 6X/7X top cover.

One last thing I thought the shifter for the transfer case on the H5F was further back. The two pictured are the same and further forward. Confused!

 

[woytovich]

I welded a "Z" into my TC shifter to get it to hit the stock hole in the hump. There wasn't really room to move it back on the hump, although I'm sure I could have made it work.

Also note that I used a stock hump in an Aqualu tub - the bugger welds to make the hump match the flat floor are visible - I'll redo that SOMEDAY...

The t-case shifter on a split case should come in at exactly the same location weather it is bolted to an H42 or an H55. The physical dimensions are the same between the 2 transmission cases.

Yes... the position of the transfer case shifter mount on the transmission housing should be the same.... longer linkages going back to the transfer case would make up the difference.

The physical dimensions are the same between the 2 transmission cases.

I think No... the later H42 has an extension housing that makes it the same length as the H55. The earlier H42s, like the ones in a 1978 era FJ40, are shorter front to back.

 

[Michael B]

I agree about the year differences. I had in mind the 87' and 86' parts transmissions I have. Thanks for the correction.

I believe the start of the spacer on the H42 in the US market was 4/85. By that time the FJ60 was the only cruiser being imported to the US. The H55F was a direct change out with no mods in post 4/85 FJ60s. I just looked at my 87 FJ60 inspection cover. The two holes pretty much line up with each other which brings up the question on the 4X series was there a different housing moving the shifter for the transfer case forward to match the transmission shifter? Also is the end of the shifter different on the H55F to shift into five gear? Don't believe any 4X series that came with a fat shifter used in the 6X series so if it is different there much have been as many of those as H55F installed in 4X series. If I could find the correct top plate for the 4X series I would probably go H55F in my 45. If not I need to decide between a H42 or H41 using a early three speed transfer case along with Fairey Overdrive or a H440F mated to a split case. I can a couple of later 4X series axles with hand brakes. One a semi floater the other a full floater. So I've got that covered. Never seen a H440F in a FJ45 but have heard it too tall. If it requires much a body lift I just keep it as a spare for my FJ62. Been driving my FJ62 to twenty-one years and to me it's the last of the old school cruisers. Still a good fit for a old FJ45.

 

[woytovich]

So are you saying the the transfer lever will always come up in the same place (because its position is based on the casting in the transmission housing) but the transmission shifter position will be different (because it dictated by the transmission top plate)?

 

[Michael B]

Yes

 

[Living in the Past]

My question is on the earlier H42/H41 and three speed on the right side there is a post with a thread hole, that is the anchoring point for the transfer case shifter. Don't have access to any parts book that would show if the linkage is different between the two, 4X/6X series. Would think to line up with the transmission shift they would be two styles of housings. Guessing it wouldn't be that hard to relocate the shifter like Mark did. The top cover of the transmission is another matter.

I was able to get my 4speed into my LWB a LOT easier than into the SWB by doing a 1" body lift on the cab. The body lift brought the bottom of the cab in line with the bottom of the bed as well, which made fabbing a set of rock sliders much easier, and the body lines still look good.
