Builds 73 FJ40 Refresh (2 Viewers)

[Living in the Past]

I had made some area on the trans cover to put a 60 series e brake handle.

Guessing the only difference between BJ and FJ axles is the routing of the hydraulic brake lines. BJ would come down the left frame rail because exhaust is on the right side. Would just change the brake line routing to the right side. Hand brake on handle on the transmission hump can run OEM hand brake cable. Hand brake drum on the transfer case shortens the rear driveshaft and requires more clearance at the back for the drum. I imagine you were already close to the torque tube behind the transfer case?

Have you found a source for the late model heater duct that's made for factory A/C? There are similar looking aftermarket evaporator units but the OEM heater is much harder to find.

I have a couple of things to try. I see at least one vendor reproducing the L200 duct aftermarket. I am going with the 4 speed I have in the storage building. So I will be posting the H55f with 40 series top, split case TC, split case TC hand brake drum parts and 40 series crossmember for sale at some point. Hopefully will offset some of the cost of this rehab.

No, my '83 BJ45 troop's hydraulic lines run on the right frame rail (passenger side in US vernacular). OEM exhaust runs outside the frame then crosses over to the left just at an angle.

Couple of questions. Why the decision to switch to a four speed (H42)? Another question are going with a roll cage or just doing away with a roll bar?

Good questions. My thinking on going to the 4 spd was to eliminate the issue with the e-brake handle and fitting the trans cover height. I see there has been a solution to the 68" e-brake cable BUT I have to modify the cross member pipe to fit the drum brake behind the TC. And I will need to add a little height to the trans cover to fit the 5 spd. And hopefully the 4 spd floor mat will fit.

There are solutions to hand brake on the rear axle. Locally there is a 72 FJ40 with an H55F and FJ60 axles. Lever under the dash is still being used. You now have the correct H55F top cover there solutions to getting the transfer shifter in the correct location for the floor mat. Might be able to use the 79-82 inspection cover to use the floor mat. Upper left in this picture.

Time is my biggest issue and space are my biggest problem continuing buying parts to see what might work has not.

So does the 3FE use the same front motor mounts as the F and 2F? You were looking for the motor mount that bolts to the bellhousing not the back right mount that is riveted to the frame? Ask because that one is commonly removed for a V8 conversion. I know you said you used a under the transmission crossmember and wanted to be sure you weren't needed that mount as well. Believe I have that one removed from V8 conversion.

 

[Engineer8000]

I needed both the frame mount and the bracket that bolts to the bellhousing, I now have both. The truck had a v8 in it when I bought it, The 3FE uses the same front mount locations.

Not much activity this weekend. I had to work Friday and cut the grass yesterday. I wanted to share this information I found on the factory AC equipment currently being offered on ebay. I couldn't get near a factory AC system for what I paid for this (seller accepted my offer) so I went for it.

The fan has 12V on the sticker but a 24V fan motor is installed, I have a 12V motor on the way.

The controller is 24V:

It comes with this harness:

For some reason the internal wires that went to the original plug were cut off. I drew the schematic. Most of the board works on 5.6 V, changing the relay to 12V and a couple resistors (R8, R9) makes this a 12V unit. I have a few inexpensive denso modules laying around that I robbed a relay from. It is for a diesel application as there is no RPM sensing circuit. That works for me since I have a 3FE where the ECU handles the AC idle up.

What the story on this unit, is it new? Looked on eBay and seen a bunch of units available. I also see a number on the controller I don't see a listing for a FJ40 or BJ40 which is what they are suppose to work with. Find it interesting since diesel and petrol.engines are cycled differently.

 

[Engineer8000]

Brand new. I read somewhere these may have been made for the mega cruiser. The 24V version is diesel, no RPM circuit.

 

[Malleus]

Merlin does it again!

So for a diesel version on a 3FE just parallel the clutch wiring with the idle up on the 3FE ECU?
Mine is from Australia so it's a 12 volt version.

 

[Engineer8000]

Yes, the clutch power is connected to the AC idle up wire for the 3FE ECU.

I've been mostly working on other peoples stuff this weekend but I did get some work done on the AC. The 12V blower motor and resistor arrived so I put those in the evaporator housing.

I found these terminals, they crimp on the end of the wire to provide mechanical strength then they are inserted in the plastic header and soldered to the board.

I had a 5 pin 3mm yazaki male connector in the old connector collection, 7118-3050. It now looks like stock.

 

[Engineer8000]

The hunt is on for the resistor connector

Removed the rest of the parts from the frame and pressure washed. Replacing the front body mounts, they had been notched for the v8 exhaust by po.
