Announcement on the Club-NISSAN or Nissan Primera Club (NPC) forum: Good afternoon. I am the owner of a Nissan Primera P12 car (I used to have an Almera N16). The car is great. For that kind of money, I didn't expect to get a comfortable and reliable car. But why, but why both Almera and Examples have steering racks leaking? How to prevent the rail from leaking, how to sort out the rail with your own hands? Where to buy oil seals and how to replace them? Is it possible to replace the steering rack oil seal on a Nissan without removing the rail from the car?

Forums and conferences are full of such messages, as well as responses to them. But still, there is no consensus on the Internet about the steering racks of the Nissan Almera and Primera. Many, having replaced only one oil seal on the Almera rail, which is very loose under the hood, report that everything is very simple. It is not necessary to remove the rail for this, and the oil seal can be supplied from a Soviet car, undercutting it slightly along the outer diameter. It is possible and so 🙂 The company Gidrolab has nothing against 🙂 But if you approach this issue professionally, then this method is not suitable.

Firstly, only one upper distributor oil seal can be replaced this way (some call it the steering shaft oil seal or the regulator oil seal) (pictured)

because to replace the lower distributor seal (which is installed on the same shaft, made of the same material, works in the same conditions and will also flow soon) (pictured)

you need to remove the entire spool, which then cannot be inserted back.In addition, the lower oil seal of the distributor on Nissan Almera and Primera rails is removed with the destruction of a disposable compression ring, which can only be put back using special equipment.

Secondly, when repairing a steering rack, absolute cleanliness is required. If you add dirt or sand to the valve spool, you can lose the power steering pump. Even a few grains of sand caught in the pump will scuff the polished mating surfaces and the rotor. After which it will have to be changed. The pump is expensive. More expensive than repairing the rail, even by professionals.

Thirdly, how to eliminate backlash, crackle knock and crack casing wear, rod wear, side oil seal leaks and much more without removing the rail?

For all of the above reasons, steering racks must be removed for repair.

But the power seals (shaft-rail oil seals, i.e. rod moving left-right) (pictured)

often not necessary to change. Their quality is not satisfactory. And at the same time, to replace them, you need to have a special tool to remove the inner power seal from the very depth of the rack cylinder.

How to repair a steering rack Nissan Almera and Primera yourself.

And yet, the Almera and Examples steering rack can be repaired on your own, but on condition that only the upper distributor oil seal is leaking and the rest of the oil seals are in excellent condition. Those. no need to get involved with a complex procedure for replacing them using a special tool.

For this, the rail still has to be removed. The wheels do not need to be removed. It is necessary to put the wheels straight and from the pit disconnect the ends of the steering rods from the swivel levers. Next, remove the cardan, disconnect the supply and return oil lines and unscrew the bolts securing the rack to the body.

The rack is removed through the hood past the battery along with the rods, after it is strongly shifted towards the right wheel. Installation is in reverse order, except that you first need to screw the steering rods to the wheels, put the wheels straight, and only then install the steering shaft cardan.

The removed rail must first be cleaned of dirt, washed with kerosene and blown off with compressed air. DO NOT wash the rail with a Karcher, as water gets inside. Next, unscrew the tubes from the distributor (they must be screwed back with care, since the fittings are screwed into aluminum), remove the distributor housing.

The oil seal must be purchased in advance in the size 19x29x4.5 mm. You can buy it from our company Hydrolab or just on the market. The procedure for replacing the oil seal itself is simple. Knock out the oil seal together with the bearing using a mandrel (a 16 high head will do).

Then drive the new oil seal back together with the bearing using a drift (a 22 high head will do).

Apply special grease to the oil seal and bearing and reassemble carefully. The bolts of the distributor housing must not be tightened to the end, but only to the moment they stop in the bearing.

Eliminating slack and knocking of the rail is a special topic for a separate article. We can only say that by a run of 100 thousand kilometers, they appear in any rail, and especially in racks with a plastic cracker, like in Almera and Examples.

So why are the steering racks of the Nissan Almera and Primera leaking?

For more than 10 years, Gidrolab has been successfully repairing steering racks of Nissan Almera and Primera cars and has accumulated solid statistics. 90% of these steering racks begin to leak at runs from 90 to 140 thousand kilometers and 98% of them flow through the upper and lower distributor oil seal.

Please note that there are two oil seals in the distributor - an upper and a lower one. The flow through the upper one is always noticeable, but through the lower one is not. When the lower oil seal of the distributor leaks, fluid enters and accumulates imperceptibly inside the steering rack. Therefore, if it flows from above, then both distributor oil seals must be changed.But the leaks of the power (side) oil seals are very rare and are associated with various defects introduced into the rail later - for example, when replacing the steering rods, the anthers were poorly installed and corrosion appeared. Or scratched and banged the polished parts of the shaft-rack.

So why does one pair of oil seals work perfectly, while the other is constantly flowing, although they work in the same oil, temperature, etc.? All our studies have shown that corrosion on the parts of these rails is extremely rare. Although for others it is a scourge. There is also no catastrophic wear on the working lip of the oil seals. But if you look at the oil seals, you will see that although they are made of a particularly heat-resistant material SNBR, they still look different. The power seals are made of slippery material, and the distributor seal material is similar to regular rubber. They are too soft and the spring is weak. It has long been noticed that if the stuffing box material is soft, then it not only quickly wears out, but also quickly loses its elasticity when working in oil. In other words, it quickly "dubs". And besides, that the spring on the distributor seals is weak, when they become tanned, leaks begin.

It turns out that the discrepancy came out precisely with the material of the oil seals at the factory. In the meantime, it was found out, a huge number of cars have already been produced in three years. And even now, the new original steering racks sold in the store do not nurse even 40 thousand kilometers, because they have been lying in a warehouse all these years somewhere, and the oil seals have already become stiff.

All that remains is to replace the hardened oil seals with new, high-quality ones. It's good that the rest of the steering racks of the Nissan Almera and Primera are very reliable. Gidrolab will quickly and efficiently repair the steering rack and give 13 months warranty no mileage limitation.

We remove the power steering pump to replace it or when dismantling the engine.

Remove the accessory drive belt (see "Replacing the accessory drive belt of the 1.6 (16V) engine").

Remove the left headlamp unit (see "Removing the headlamp unit").

We pump out the fluid from the power steering reservoir with a pear.

Holding the pump union with the "22" wrench, with the "17" wrench, unscrew the union of the discharge line tube

We take out the tube fitting from the hole of the pump fitting and remove the tube from the pump body

Squeezing the filler pipe clamp with pliers, slide the clamp along the hose

Remove the hose from the pump connection

We insert plugs of a suitable diameter into the holes of the tube, hose and union of the pump body.

Turning the pump pulley, we align the hole in the pulley with the head of one of the two bolts securing the pump to the engine bracket

Using the "10" head, unscrew the bolt securing the pump to the engine bracket. Similarly, turn away
second bolt.

With the same tool, unscrew the two pump mounting bolts on the opposite side of the bracket

Insert a screwdriver between the pump casing and the motor bracket and squeeze the pump casing from the bracket ...

Install the power steering pump in reverse order.

We adjust the tension of the accessory drive belt (see "Replacing the accessory drive belt of the 1.6 (16V) engine").

Fill the power steering reservoir with working fluid and remove air from the system (see "Bleeding the power steering system").

It will not be difficult to change the fluid in the power steering Nissan Almera H16. First of all, do the preparatory work and cover the hinged belt so that oil does not get on it and remove the tank with washer fluid. Then start pumping out the old power steering fluid from the barrel with a large medical syringe. Before you start pouring fresh liquid into the tank, it will not be bad if you rinse it thoroughly.

Further, the algorithm for replacing the power steering fluid on the Nissan Almera N16 will consist in removing the return hose and installing it in a separate bottle and close the return pipe in the barrel with a plug and filling the tank we begin turn the steering wheel when the engine is not running (it is advisable to hang out the front of the car).

We repeat this procedure until fresh clean liquid runs out of the return hose.
