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.
