@beno,

It's Robbie's fault.....

 

[Tapage]

HD-T to H55 is possible, then why can't the same clutches be used for a 1FZ to H55?

don't have an answer to your question but .. we have plenty of 70 series 1HZ with H55F altho that H55F it's different in input shaft from the one I have in Tencha .. ( factory there ) since Tencha have 10 spline count input and those behind 1HZ are in fact 21 spline ..

I also have the bellhousing that match 1HZ with modern H55F .. and the pattern looks the same ( to the BH ) as found in my H55F on Tencha .. so I plan to use my drivetrain in the long future when I swap my 2H for a 1HD-T .. but I suspect the length on the inputs from the early H55F vs the late one are different ..

 

[Delancy]

don't have an answer to your question but ..

I've figured out that 1FZs and 1HDs share the same input shaft spline count and length, although bell housings are different.

H15Xs interchange between the two, short of bell housings/clutches.

Why is this relevant?

Still seeking the elusive 1FZ/H55 marriage and this is the same dead end, since there were as many HD/H55s as there are 1FZ/H55s.

BUT

When time allows, going to compare the H151F and H55 (4X) bell housings and flywheels to see if a remote chance that an adapter at the block, similar to MS-75s, might make this marriage even easier.

Pretty much, run all H55 components, opposed to sourcing bits of non-US, for a 1FZ marriage.

Clutch may not be stout enough, I dunno, but they put the things behind Tree Fiddy's in Oz, and can't imagine the FZ to be kicking out much more ass than a Holden.

Dirty harness

Not as dirty harness

Appears the PO was fairly good at hacking into the harness, which kinda sucks hunting when hunting for the obvious.

Now hunting FZJ7X schematic.

 

[wardharris]

Keep at it Chris - there has GOT to be a solution that can serve others as well.

Given number of 1FZs and H55s in N America, this is a good thing to solve for.

 

[Delancy]

Tenacity- when stubbornness trumps ignorance.

 

[Tapage]

I don't see an issue with the clutch, I mean you can have 1ZF flywheel ( 8 bolts vs 6 bolts ) and run what ever disc you want ( can ) on tranny side .. the real deal it's bellhousing and adapter ..

 

[Delancy]

First phase of this project is tentatively scheduled to kick off in March and scrambling a bit to make a few determinations and round up necessary parts.

The goal is drivetrain swapped, wired, running and driving with lengthens rear driveshaft, only, leaving axles as they are, so that the suspension phase (2) can follow.

What I've got:

Rebuilt 1FZ-FE long block (OBD1)
H150F & H151F (need to decide)
HF1A
Frame Mounts
Motor Mounts (front and rear)
Engine Brackets
Crossmember
Crossmember Brackets
MT ECU (OBD1)
MT Harness (OBD1)

What I don gots an needs, but ain't easy to source:

FZJ7X Radiator
FZJ7X Radiator Shroud
FZJ7X Heater Valve
300mm Clutch
Flywheel
Pressure Plate
FZJ7X clutch slave
FZJ7X clutch master
FZJ7X clutch pedal assy (for hydr)
LHD AC, harness, control switch

What I don gots, but think US stuff will work:

OBD1 MAF
Intake tube
Air Cleaner housing
Fuel pump
Fuel pump relay

Sure a ton more, but a preliminary list, presented in the unlikely event anyone has suggestions for compatible parts that CAN be found in NA, or sees anything I'm clearly missing.

 

[scottryana]

Get a custom Ron D. radiator, electric fans and shrouds, much easier than sourcing an FZJ7x rad, arguably better quality, the fans can be thermostat controlled and switched for water crossings, etc. Simpler and dare I say better setup IMO. But I don't know how much space you are working with and what size electric fan you could fit but in my 55 I ran a 16" fan and it had no problems holding temp.

 

[Delancy]

Are the aluminum radiators that's much thicker?

Why couldn't one be used with the 1FZ fan, if not?

 

[scottryana]

I would imagine you could spec the radiator whatever thickness that you wanted. You could use it with the 1FZ fan but since this is going to be your wheeling rig the electric fans give you some good control for an offroad truck. And if the 70 series rad is like the 80 series rad it has plastic tanks etc.

 

[joekatana]

Hey Chris how about using a HZJ70 radiator would that work?I can probably get those OEM or the cheaper aftermarket version for you.

Have you tried Toyota Venezuela yet for the parts you need?Contact Tapage about this I believe he has some connections there .

[cruisermatt]

And the all important question... Will we be seeing some FC Fab metal-magic?

 

[gifu]

FZJ7X Radiator: there are china suppliers that only advertise to Aus, but will ship to U.S.
I'm running one of these in my HZJ74 conversion and I was impressed with the quality.
ex:http://www.ebay.com.au/itm/56mm-3ro...ta-Land-Cruiser-75-Series-HZJ75-/301233916411
FZJ7X Radiator Shroud: it's not pretty... but I cut up an early FJ40 metal shroud.
FZJ7X Heater Valve. Is this different than HZJ75? otherwise should be available from ENS Toyota.
300mm Clutch: if you run H151, should be able to get one through Toyota. If you are running H150, and want a 300mm clutch... I _think_ the H150 splines are different. But i might be confusing this with running an H55F and a 300mm clutch
Flywheel
Pressure Plate: Got mine from Toyota
FZJ7X clutch slave: FJ60?
FZJ7X clutch master: FJ60?
FZJ7X clutch pedal assy (for hydr): The pedals changed a tiny bit over the years. I had to modify mine. Then on the second one I did, I just used a RHD pedal (easier to get) and modified it to work. Wasn't that much more work (if you can't find a LHD pedal.)
LHD AC, harness, control switch: Gooooooood luck. The underdash system on the 70 sorta... sucks. It's overly complicated, leaky, large, and hard to get parts for... It might be worth thinking about a hot-rod air system.

 

[Delancy]

You could use it with the 1FZ fan but since this is going to be your wheeling rig the electric fans give you some good control for an offroad truck.

Good point, although I never had any cooling issues with the 80 and when we wheeled in the heat of summer, I ran the AC if I wasn't listening to someone holler:

"gonna have to bump the throttle a bit, turn right, then immediately left.....and hope for the best."

When talk of SCing this rig was occurring, discussed intercooler and other cooling idears with several, Dan saying something about marine fans.

Looked into a few options and, given their recommendations for assumed cubic volume similar to the engine bay, along with calculating an outlet the size of the rear vent (in place of side marker) they claimed two relatively small fans could lower temps 25-35%, depending on what range was specified.

Not necessary in this case, but an interesting thought process.

And if the 70 series rad is like the 80 series rad it has plastic tanks etc.

Can't say....know there's one part number from '90-'99 now.

Checked a Pig's radiator and it's the same physical size as the BJ73s.

Hey Chris how about using a HZJ70 radiator would that work?

Good question. Will check the ports on HZJs and see if they're the same.

Based on other similarities and cross referenced parts I've noticed, almost think the FZs/HZs were engineered with continuity in mind, so it's very likely.

Have you tried Toyota Venezuela yet for the parts you need?

No habla Espanol, señor.

Bahaha.

Alberto's wired in there, so I'm sure an option.

Good to know. Australian's sound to have had similar luck with those, too.

FZJ7X Radiator Shroud: it's not pretty... but I cut up an early FJ40 metal shroud.

As close as the FJ55 and VMJ73 radiators are, assuming a 1FZ fan is similar in diameter (which I'm going to check) it looks like a Pig shroud could be used, but guessing it could be fabbed, regardless.

Cooling systems scare me, based on actual experience with several domestic diesels and reported experiences of others on the 1FZ.

My thinking was, if it's all FZJ7X OE it takes the thinking process out of the equation.....guess adds thinking to professional endeavors to fund acquisition, though.

FZJ7X Heater Valve. Is this different than HZJ75? otherwise should be available from ENS Toyota.

If the BJ dash and heater core remained, would I be better served with a replacement heater valve for it, since it's operated by the existing controls?

300mm Clutch: if you run H151, should be able to get one through Toyota.

Toyota USA?

If you are running H150, and want a 300mm clutch... I _think_ the H150 splines are different. But i might be confusing this with running an H55F and a 300mm clutch

There were several renditions of the H150F, but only one vehicle that it came behind the 1FZ, being a 75. All FZJ MTs have the same length and splines, too.

I know all FZJ80s had 300mm and think, being operative, the FZJ75 did, too, but have bell housings for both.

More my question now is, which to run based on the gearing.

Lower 1st and marginally lower 2nd, with either the same, slightly higher in 5th, which may bode well for a wheeler that'll see highway speeds.

Dunno....and posing for discussion.

Flywheel
Pressure Plate: Got mine from Toyota

Toyota USA? (Yours is an HZ, so they do have those in the system. No MT FZs came to NA, so not accessible)

FZJ7X clutch slave: FJ60?

Alberto actually donated one.

FZJ7X clutch master: FJ60?

Alberto donated.

Think it can be had in the US, though, since I did get a 7X brake master and booster for the Pig here.

FZJ7X clutch pedal assy (for hydr): The pedals changed a tiny bit over the years. I had to modify mine. Then on the second one I did, I just used a RHD pedal (easier to get) and modified it to work. Wasn't that much more work (if you can't find a LHD pedal.)

So a hydraulic clutch pedal is offest the distance from the master?

LHD AC, harness, control switch: Gooooooood luck.

I thought I had hit a home run a few months back, when buying a complete HVAC system out of a 97 with harness, controls, even the piping, in Australia, never thinking that it'd be moved to the LH side, and for chump change, too.

Glad I read that it wouldn't work before it shipped....

The underdash system on the 70 sorta... sucks. It's overly complicated, leaky, large, and hard to get parts for... It might be worth thinking about a hot-rod air system.

An option that will be explored. Should've gone that route on the 55....

I've been looking at a Pigs the last couple of days, packaging for shipping, and it's appears to be possible to fab an evaporator housing, use a 60/70/80 evaporator core ( whichever fits ) then the balance firewall forward could be 1FZ.

The AC switch for BJs shows available but (thinking) 24V, where FJ7X is not.

May look to see how the RHD FZJ7X controls are oriented, get it and the harness, then try to figure a way to modernize the evaporator to, at least, 97 80 Series levels.

The more this is like an 80, the easier it'll be, but some aspects aren't adaptable and not many custom options ( besides the complete retro fit ) for evaporators.

And the all important question... Will we be seeing some FC Fab metal-magic?

Don allocated time in November and will have something there, hopefully this 73.

Want to have a little time to drive after the conversion is complete, kind of a shakedown run, so it'd be lesser a score that his normal, since the drivetrain would be complete.

Love to drop off with the RS housings, geared diffs, and all necessary axle parts, wheels and tires with no more a directive than to "cage it, link it, chop where necessary" and make it the coolest wheeling 73 on the planet.

As a repeat haji to the mother church in East Stockton, I am a true believer in all things Don (and Georg) but without seeing the results, I gotta mention this Spanish 73 here in Washington state. The three of us (you, Carl, me) have the same Godfather (Chris Spaulding).....

Just sayin, Carl set a high bar...

 

[scottryana]

Well I was not just talking about overheating. I was talking about electric fans running on a thermostat are better in many situations than a belt driven fan. i.e. they don't turn on until they are needed allowing the vehicle to come up to operating temp more quickly, they only run when they are needed, they can be switched so that if you go through any deep water you can flip them off and not have the worry of sucking a fan blade into the radiator.

The radiator can be custom made, so that on a project like this you can plan out any other things that might be desired. Moving inlet and outlets slightly, not having a transmission cooler in the radiator since you are running a manual thus giving the system more capacity to cool only the engine. etc. Given what I know the costs will be to ship a 70 series FZ radiator, shroud and fan, I bet you would break even on the cost and have a system that was more tailored to your truck's usage.

I am a true believer in all things Don but without seeing the results....

In 1506, a similar statement was made by a Cardinals, both friend and trusted adviser, to Pope Julius II, regarding the commissioning of an young, obscure artiste to do a little paintin' in the chapel.....

Cardy says

"Doooodd....you did what?"

"This dood ever painted da roof, before?"

PJ2 replied:

"Nah, dawg. Kinda told him a little 'bout the house here, didn't even axe him what he was gonna paint....but it's gonna be so fawking epic, folks'll be talking about it for a thousand years"



I dunno if Metalangelo will even chop on the 73, honestly, since all that's been bandied around is November of '15, after nagging Georg for a couple of years and Don this last.

Drivetrain will be complete and running, accept axles and whatever steering gearbox is determined to work.....after front axle location is finalized.

Hoping well received.

If not, always have a little pork to carve....some kind of canvas will be there.

Just sayin, Carl set a high bar...

I'll try to not trip on stepping over it....













I'm joking, of course....could not resist.

Agree.

I'll try not to disappoint.

 

[Delancy]

I must have been added to some kind of importation "watch and screw" list, since the NOS Pig speedo was destroyed, last tranny pallet was held for two weeks at my expense, and now this notification:

"Please be advised that this is a HOLD notice for an import shipment to which you are a party.

Hold Reason: VACIS X-RAY EXAMINATION
This shipment has been profiled for VACIS X-Ray examination.
Cargo availability date is delayed.
ADDITIONAL CHARGES TO FOLLOW."

The last line the most concerning, as well delay of the one engine mount bracket that's necessary.

If it were for the value of the mechanical HF1As, since necessary to eliminate the ECU, I'd box the H151Fs with no bellhousings and DHL the damn things, knowing full well the screwing amount, up front.

Rant over
