I’ve greatly enjoyed the threads on here about other members journeys so want to contribute my own.
Having an affinity for Toyotas since getting picked up from school in a hj45. Now driving a 200 series and the wife in a rav4 I thought I’d keep the theme going with a hj47 that I can pickup my son one day in.

I found this one on marketplace in a small town 2 hours out of Brisbane. It had been online a while and I thought I’d find out why after missing out on a couple of my earlier choices. Being sold as registered and roadworthy was also a big plus as I could get in and start driving from day 1.

Well I quickly found out that calling it roadworthy was a stretch but I was immediately taken by this yellow mustard Ute. First inspection identified some obvious issues, cracked windscreen, a variety of oil leaks. Suspension bushes almost non existent. Tie rod ends very possibly original from factory. But none of this mattered, it ticked the main boxes which was basically all original, with a manageable amount of rust. I quickly made a deal, and 5 days later I had it in my shed.

I have had a couple of weeks now to start a few repairs and come up with a plan.

To date I’ve changed the oil, the rocker cover gasket and spent a couple of hours cleaning 40 years of mud out of the chassis rails. It just keeps coming!

Stage 1. Get it drivable.
Clean and paint chassis in situ.
Terrain tamer kit on order and will fit myself. Brake service at a mechanic. Possibly steer it knuckle rebuild.
Tie rod ends and wheel alignment.
New headlights and indicators

Stage 2 Tray. Remove tray, treat or replace timber bed as needed. Panel beat and remove rust and paint. I have discovered a couple of tray mounts have been welded in place. Possibly due to lack of suitable bolt at the time. So some effort to correct this.

Stage 3. Upgrades. Have sourced a 5 speed gearbox and most parts. At this stage will do end bearings and any other mechanical necessary. Power steering, have the steering column on order, factory power steering box currently somewhere in continental USA but it will come my way thanks chamba.

Stage 4. Body. I’m going to try very hard to not start anything on the body until earlier stages are complete. Other than the windscreen it is all serviceable. When I do I’ll probably get the seats out to an upholstery and while not driveable I’ll pop the roof off and try and resolve some rust around back panel mounts and floor pan.

If you made it this far I really appreciate your interest and I’ll try my best to capture the journey.

Beautiful Ute, love the mustard and really love the truckie pin stripes. Can't wait to see the power steering in its new home.

Somewhere I've got pictures of my boy at that age in my LX back in Adelaide. Now he's driving them around like an old pro. Great job immersing the lad in quality vehicles. My son started 'helping' me in the shed when he wasn't much older than your lad: a few months ago he put a new water pump on his Camaro with very little guidance by me. Very rewarding.

Beautiful! I still got no kid but the troopy is to see them drive it one day.
 
Wow.. nice start for an HJ47, looks very clean.

I know this is your vehicle, but I'll just say my usual that the 5 Speed upgrade, and Power steering are entirely overrated upgrades in an HJ47.

Best wishes for the project! Bunch of 2H resources below in my .sig if you need them..
 
5speed is pretty much a 4 spd. The first gear is too low. Often start on 2nd.
 
Having put power steering and an H55 were the two best upgrades I ever did to my HJ47. But that's what makes this site such fun to belong to.

I understand that the HF55 5 spd box is a big+ for the US interstate/highways. Not necessarilly for other parts of the globe (e.g. a little and mostly mountainous country like Greece), so I concur with @duncanrm

PS. The maximum distance from the sea in Greece is 137 kilometres (85 miles). Because of its mountainous terrain and extensive network of archipelagos/islands, no location in the entire country is further than this from the coastline.

At 100 KPH ( the strict speed limit in most of Australia), with 4.11 diffs the RPM in fourth gear is approximately 3000 RPM. I never enjoyed the sound of the 2H at that RPM. In fifth gear in the H55, 100 KPH it's closer to 2400 RPM, which is a very pleasant rev range for the 2H.

Look at it this way: you could cruise all around town in just 3rd gear in a 2H. 3000 RPM would keep you within the speed limit of almost all city streets. But around town you shift into fourth. Why? Because keeping it at three thousand RPM would be unpleasant and unnecessarily increase wear. So you shift to the next higher gear.

An H55 simply allows you to keep that engine in the sweet spot. And given this HJ47 has an H41 currently, the 1st gear is identical. I'm not sure how anyone can fault the option of an extra gear to drop the rev range and reduce wear. Is it strictly necessary and required? Obviously not. But again, that's what makes this site interesting.

Good points, thanks for sharing!

PS. For my BJ45 Pup resto I will swap a 2H and FJ45 axles (final drive gear ratios 3.7 to 1, like in the HJ60). Following this path I expect, keeping the great H41 4spd I have, to partially compensate the lack of the 5th gear.

In my HJ47 I had the H55 with the 3.73 diffs. With the turbo on the 2H it did very nicely (I eventually swapped to a Vortec 350, and it would easily do 150KPH, though I still kept it around 130). It cruised comfortably at 130 KPH at about 2500 RPM: keeping up with traffic and allowing me to listen to music at a comfy level inside. The 2.5:1 4WD low and the great torque band still kept it respectable off road.

The H41 with a 3.73 diff is a great combo. It makes 1st gear usable and gives you the lower RPM on the highway. It's a great combo. On the 2F however, there's simply not enough power to run larger tyres with the 3.73s. But for stock setup it's ideal. The 2H has a lower power band and it loves the RPM range the 3.73s provide.

Great news, music to my ears @Chamba!
Actually it should work: the clever Japs did use this combo in the HJ60 (which is slightly heavier than the J45/47 Pups).
In respect to the tyres I'm considering stock, e.g. 205R16 (29 inch), OEM size in the European market for both Cruisers...

Busy week but squeezed in some wire brushing and rust treatment whenever the hoist was free. A couple coats of chassis black Friday morning and by afternoon I couldn’t help myself. The terrain tamer parts have been looking at me every time I go into the workshop and I had a couple of spare hands so threw the back end in. I’ve cut some corners opting for a rattle can finish but the combination wire brushing / fertan rust converter / raptor satin black has come up rock hard and I’m more than happy. Hopefully can get the front end in this week.

Also picked up a h55f and 60 series diff for my eventual 5 speed conversion. I have found a guy building 40 series tops for these gearboxes, only an hour from me, but I am still measuring the cost / benefit of this as most people seem to get by fine without them. I’ll also throw in some pics of the wrecks I’ve been sifting through to find the gold. The only problem I have with this is trying not to bring them all home.

You'll want to throw the 60 series front diff/axle in too. The 60 series diff is 2" wider and with a wider rear diff and narrower front you'll go through front tyres flat chat.

I did this on my LX. 60 series rear diff first, and was shocked how quickly the front tyres began scrubbing down. I put the front 60 series diff in by moving each hanger outboard 1" and solved the issue. PLUS, I could not believe how much better it handled with the wider stance.

An added plus was that it didn't want to pull from rut to rut when braking at intersections because now the track was actually a similar width to modern cars.

PS that 45 appears to have everything AND the Kitchen sink. Score.
