While the weather was bad, I decided to try and reduce the amount of smoke that the engine was producing. This seems to have got worse since I changed the cylinder head, and so it seemed like a good idea to start with the fuel injectors. I had some spare ones, so I dismantled them and cleaned the parts. I managed to assemble 5 good ones out of the eight spares I had. Today I finished putting them back in the engine, with new sealing washers. I’m glad to say that the smoke is much reduced once the engine is warmed up, and it idles more smoothly too.February 3, 2021 at 3:24 pm #1795
The next job is now on the bench. The steering box has slowly been leaking oil from the bottom seal. This is a common fault. You can just change the oil seal, but I think that the bearing has some play in it, which means any new seal will soon start to leak. So, a complete stripdown and inspection is required. The drop arm is quite difficult to remove. I applied a bit of heat and then belted it with a hefty hammer. It soon came off. We shall see what it looks like inside..February 15, 2021 at 10:41 am #1801
I found out that the output shaft can be removed without disturbing the input shaft or the piston shaft. The top cap bolts are removed and then the adjusting lock nut. Then by rotating the adjustment screw, the cap is gradually pushed off. Then the output shaft can be tapped upwards and out of the box, using a soft faced hammer.February 15, 2021 at 10:42 am #1802
The top of the box can then be inspected, the bearings look good, and there was no sideways movement.February 15, 2021 at 10:43 am #1803
The shaft looked in reasonable condition, with a slight groove where the seal had rubbed.February 15, 2021 at 10:44 am #1804
I put this into the lathe for some light sanding with fine wet and dry paper.February 15, 2021 at 10:50 am #1805
The seals were removed from the bottom of the box. They were really soft and loose. No wonder they were leaking.
New seals were bought from FPE seals, online. The main seal is made by Polymaster, part number SA175125-028P, and the second seal that goes after the circlip is oil seal 32mmx45mmx6mm.February 15, 2021 at 12:47 pm #1806
The main seal is a hydraulic piston seal, which according to the Land Rover forum is the same one that is included in the genuine LR kit, at a price of £150.00! The cheaper kits have na ordinary oil seal, which is not any good. So here is the special seal installed in the box, with the washer and circlip. The second oil seal goes in after this.
Then the shaft can be re-fitted into the box.February 15, 2021 at 3:32 pm #1807
After the shaft was replaced, and the top cover was put on, I checked the backlash in the box and adjusted it. Then the box was wire brushed and then given a coat of paint. It is now ready to go back in the car. Hopefully with no leaks!February 24, 2021 at 12:25 pm #1809
The front axle is now back on the car with the replacement springs. Now the assembly of the hubs can be done, and antiroll bar. It shouldn’t be long befre she is back on all four wheels.March 9, 2021 at 3:38 pm #1810
The hubs and anti-roll bar are now fitted. I have a turbo anti-roll bar that is new old stock, that is the one that is suitable for UMMs with four dampers on the front. Unfortunately, it does not fit with the GKN hubs, and so I am using the old one, after cleaning and painting.So I have a turbo anti-roll bar for sale if anyone wants one.
I now have all the pieces ready for finishing off the front axle, but I am hesitating to do this. It means fitting the brand new discs, and then it might be sitting unused for a time while I finish the rear floor. So I will probalby do the rear cargo floor next and then finish the front off.

Cutting out the rear floor. The longitudinal chassis sections are OK except for the rearmost part. These will be patched as the work progresses. New angle iron cross members will be welded in before a new floor is installed. The floor will be galvanised steel if I can get any. Apparently there is a shortage of steel at the moment.April 5, 2021 at 3:43 pm #1821
Here is a progress report on the rear floor. New support crossmembers have been welded in place and the rear of the chassis has been patched up. I am now intending to use Buffalo board for the rear floor. This is waterproof plywood with a patterned non slip coating on one side. This board will be screwed to the supports from underneath.
I have also fitted a spare wheel winch onto the crossmember. This is from a Ford Ranger, and it lifts the spare wheel up under the car for stowing.April 5, 2021 at 3:49 pm #1823
It winds up and down using a shaft I made up with a socket welded to the outside end.April 5, 2021 at 3:50 pm #1824
And here is what it looks like with the door closed.April 16, 2021 at 3:10 pm #1825
New dampers are now mounted. The back is all ready for the new floor, which is on order and should be arriving in the next few days. Once that is fitted, I will be concentrating on assembling the front hubs and brakes. Then new tyres on the wheels, so it will be able to be moved again. I have a list of jobs to do before the MOT, but not too long.

The rear floor arrived and is now in position. This is the Buffalo Board I mentioned previously. It is supposed to be waterproof.April 23, 2021 at 3:20 pm #1830
The other job was to finish assembling the front hubs, and install the brakes. That’s all done too.
The new tyres are on order and should arrive next week. They couldn’t fit the tyres straight away because the valve holes in the wheels are an “old” size and too big for the tyre valves that they now use. Rear lights will probably be the next job.May 4, 2021 at 4:09 pm #1831
New tyres and wheels fitted at last. This is the first time the UMM has sat on all four wheels for a few months, and since the replacement front springs have been fitted. Thankfully, she sits pretty level, which is a relief.
So I took the opportunity to start it, and drive it up the drive and turn it around.
Next job will be the rear lights, which are on order.
