Mister Blue the sunburned 2004 diesel 105

[John Young]

I appreciate this dialog. I think I might put something on the 80 forum because this is basically an 80 frame. Here is a photo of the item in question:

48313-60010

The senior guy pointed out the two places where the bump stop hits

 

[John Young]

Here is a better view of the bumpstops

They are staying in for now at least.

The axels are looking better:

They will both get a lick of paint before going back in.

And here is Mister Blue's comparatively tiny transmission. It will get new synchros and a taller 5th gear unless we have to do that by changing the ratios in the transfer box.

I was going to get the kit from Terrain Tamer but their catalog is confusing me a bit.

 

[John Young]

Here is the kit I -think- I need for Mister Blue. If anyone reading this happens to know for sure...

.711 to .838 would be a shorter gear, not taller.

 

[ClassyJalopy]

.711 to .838 would be a shorter gear, not taller.

I believe it is the inverse of that! From 0.838 to 0.711

Whoops you’re right, I read that wrong.

Seems like a better solution for a taller final drive would be taller tires.

I was trying different stripping methods on the old bottom piece and it literally was falling apart with only the slightest pressure. I decided to see whether maybe Andrew had been right and the decals could be reused.

And indeed, 'decal' is not really the right word for this. The plastic label is stiff and fairly rigid.

What is interesting here is that the openings are identical, left and right. It is only the label that determines whether it is for a RHD or LHD vehicle. The plastic itself is identical!

But this is taking a long time to do properly. Meanwhile Mister Blue is being driven around like this:

Perfectly functional, just not pretty to look at.

We have a full HVAC control unit for a LHD 105, brand new OEM. If you are interested?

Cheers

Thank you, that is very kind. I might need it for Missus White and I will PM you.

Had a bit of a setback, now that the engine and transmission are out and being inspected.

Shelby, the owner of PowerTec, feels that what happened is that the nut holding the power steering nut gear came loose and forced things apart. It got repaired but this would have forced the two halves of the castings in this area apart which would explain the poor oil pressure I had been worrying about.

Fortunately the castings are available

The back half has the oil pump in it.

This is a 450k km engine. I will go over on Monday to discuss whether redoing this engine or getting a different engine makes more sense. I actually could buy a 14K km fire truck engine for 25K AED / 7k USD and I am mulling that over. It would still need a new timing belt but other than that it -should- be a drop in.

[zgfiredude]

Just something to remember.....while the miles will be low on the Fire Truck.....it will likely have had a fair amount of run time in addition to the travel/miles. Be thorough in checking it out.

Suggestion from a retired firefighter.

i woudl buy that half-cut in a heartbeat if i had the chance

 

[John Young]

I went over and had a look at the present engine myself. 450k km. Not bad aside from the bolluxed front timing cover casting, which looks to be due to an incorrect install of a power steering pump or maybe vacuum pump that went bad.

At first glance the camshaft looked bad

but when I rubbed it, it all came clean. I could not see or feel wear on any of the lobes

I am going to have a look at a couple of possible engine swap candidates. I need to make up my mind....

Just FTE it, or FT, if you hate electrics going to an engine. So much more engine, same reliability

I am looking at a 1HD-FTE bolted to a H151F. Thoughts? Is the engine wiring harness all I need?

 

[Moridinbg]

The H151F is an amazing gearbox, much more robust than the likely R151 currently in it. It too suffers from too short 5th gear, 120km/h is at something like 2800RPM.
You need the harness for sure, the ECU and the immobiliser. The Immobiliser can be removed, I am sure plenty of people around you know how to do it.

 

[John Young]

I went up and took a look with the senior mechanic who will actually be doing the work. Ultimately we decided to go with just a 1HD-T instead and retain but rebuild the existing gearbox, changing out 5th gear, with the idea of later refitting the better gearbox. I tend to be a fairly conservative driver. The other gearbox had the electric center diff lock so there would have been some retrofitting I think and they wanted 1500 USD for the gearbox

Here's the engine:
It c

It comes with all the necessaries, including the air cleaner an hoses to the air cleaner. No intercooler. Simpler setup albeit a more primitive engine.

Here is the transmission we were looking at:

The 1HD-FT seemed to be getting a little challenging in terms of the installation. The 1HD-T is more similar to the existing 1HZ. Here are the numbers:

1HZ:
The 1HZ Toyota Landcruiser 4.2 litre (4164 cc) diesel inline 6-cylinder 12-valve SOHC (single overhead camshaft) is of the IDI or indirect injection design,.
Output is 96 kW (129 hp) at 3800 rpm and maximum torque of 285 N⋅m (210 lbf⋅ft) at 2200 rpm.

1HD-T
The 1HD-T is a 12 valve 4.2 L (4,164 cc) straight-6 SOHC turbocharged diesel engine of direct injection design. Bore and stroke is 94 mm × 100 mm (3.70 in × 3.94 in), with a compression ratio of 18.6:1.
Output is 164 hp (122 kW; 166 PS) at 3,600 rpm with 361 N⋅m (266 lb⋅ft) of torque at 1,400 rpm.

1HD-FT
The 1HD-FT is a 4.2 L (4,164 cc) straight-6 24 valve SOHC turbocharged diesel engine of direct injection design. Bore and stroke is 94 mm × 100 mm (3.70 in × 3.94 in), with a compression ratio of 18.6:1. Known as the "multivalve" it has 4 valves per cylinder (2 inlet, 2 exhaust), central vertically mounted injector, and no glow plugs but rather an intake glow screen heater (like the later electronic 1HD-FTE below). The 4 valves per cylinder are actuated by the SOHC, by using bridges so each rocker actuates a pair of valves.
Output is 168 hp (125 kW; 170 PS) ECE at 3,600 rpm with 380 N⋅m (280 lb⋅ft) of torque ECE at 2,500 rpm.

From this it seems like the 1HD-T is the one that best fits me. Materially more horsepower and quite a bit more torque down low where I tend to drive anyways. The 1HD-FT does not really buy me much for all that additional complexity.

The senior mechanic had another look at the 1HZ that came in Mister Blue and concluded that it had been rebuilt, which is what I had been thinking given the pristine shape of the camshaft on a 450k km engine. Here are a couple of photos:

I then had a look at the original transmission parts dismantled for rebuilding

There are some signs of wear. Nothing catestrophic, but I suspect that the transmission also has been gone through before because despite the groves in some of the gears there was no shiny bit in the oil.

There was some material wear on the main shafts of the transmission

I'm still of the view that this transmission can be rebuilt and put in good condition with some flame deposition welding on the worn shafts.

 

[John Young]

Ok, so I pulled the trigger on the 1HD-T engine. The seller pulled the automatic transmission off of the engine.

And after some negotiation, all over Whatsapp, I had transport--Nabeel (the bearded man), who I have used before, picked up the motor

And then a little while later it arrived at PowerTec

Complete with 100 series air cleaner and intake hose

24v starter and a lot of scary connectors....

While I was up there I picked up a set of JDM running boards

I have been driving the 1996 troopy and that is what I had with me today. Yesterday I had a company function out in the desert with it where it served its essential purpose.
