Recovery of oil pump
Briefly:
The pump — as the name suggests that the device is pumping oil, pumping system under pressure. The role of an oil pump in the engine, it is difficult to underestimate.
The basis of motor that converts the energy of combustion into torque is the crank mechanism. You can certainly say that the explosion energy is first transformed into a reciprocating motion and then into a rotary, but if a little thought, you can understand that without the connection of a crankshaft with the pistons through the crooked thorn and rod, will be only "forward-emitted" by the pallet movement and no return :) on the other hand the crank mechanism is not only a crank and connecting rod ) and piston, and the finger of the piston and the crankshaft and the flywheel, and even the engine block... In the base motor is the crank. In turn, crank the engine there is a little feature is the bearings, saying that it is only the ear is wrong, because the ear is only a part of the bearing, and the leading part of the bearing is the lubrication unit, without the oil film will not slip...
Here in this persuasion, I have failed You to the fact that the oil pump is one of the most important parts of the Internal combustion Engine.
Types of oil pumps are not one and not two. In automotive engines uses a trochoid oil pump. Another name of Ge-Rotor, not to be confused with a gyratory helical pump are two different things. Ge-Rotor — GEnerated ROTOR.
This pump consists of 2 gears, internal and external.
Internal gear has N teeth.
External — N+1.
When rotating the gear, creates N dynamically changing volumes. The volume increase and decrease.
By increasing the volume creates a low pressure zone, it is the first phase of absorption. Further rotation of the gear, the volume decreases and compresses the working material (if the pump works with gas, a Prime example is the compressors of the system Roots, and once I've considered their work) or a "pump" when the pump is dealing with liquids. The last phase will be the displacement.
Wanted short... failed.
And so, the primary trouble with pumps is that for the most part, to reduce the cost of General construction, gear pumps are made from "powdered metal", designed by the plant to any certain operating modes and resource. But against high loads and vibration, to happen, to put it mildly, a failure...
That factory oil pumps motors series ZZ can be called successful. One of the weakest parts of the engine, and assuming the above information is, unfortunately, one of the most important...
In my Turbo motor, I used the reinforced gear CircuitWorx made of alloy and quality of stalyga...
After disassembly of the motor gear was discovered bullies, not fatal, but unpleasant:
Thus the working parts of teeth in excellent condition
These gears without problems skated tens of thousands of kilometers, for several years, with a supercharger, under loads comparable to factory. And even the knocking the engine was given more than 1.2 atmosphere pressure at idle and atski warmed oil. Gear survived the breakage of the pins of the crankshaft, and if you've ruined everything.
they remained alive. That's why I want to pay tribute to these gears, and animate them. Given that the firm no longer produces them. And $ 400 for a new one... nothing to sneeze at. Perhaps later, someone they will serve as well as me.
After polishing on a magnetic plate with 2 sides, we get the perfect gear.
Find a pile of rubbish, more or less living body of an oil pump, and send it to the sink
Grease with engine oil and install gear
What happens next is standard procedure for the inspection and if side clearances and gaps between the teeth are within the tolerance.
The clearance for the plane grinding of about 14.5 hundredths of a millimeter.
Is the nominal clearance 0.03 — 0.08 mm, critical — more than 0.16 mm...
We are actually in a critical situation. This was to be expected, everything has a price, the grinding is. Therefore, the housing of an oil pump is also sent to the grinding... it's no longer about 0.09 mm. and we get a gap somewhere in the 0.05 mm. Install the lid, screwed the 5 bolts to a torque of 10.5 Nm. and all... ready to work. Better than new :)

Great! There is an alternative CircuitWorx?
in addition to MWR in England sell. I bought a new motor. the same En24. And there are suspicions that MWR buys them

Sold. And the idea to have to drive has on the motor
and Toda racing? shows how
and what do you have then?
Watch. A lot of interesting things. Just time to write there. Yes, and thankfully not all of it

Once upon a time I had restored the pump oil more on diesel and the Vectra, then I'm not grated the gears and the case, and eventually after about 100 meters the engine so stuck that I almost windshield has not made a head, at first I thought something hit but no, the pump from heating the wedge caught.
In the cool!
well, I'm not sandpaper polished it ) and after that all clearances measured. all admission

what to do if nutriance "aluminum", the pump identity of the Heckler?now figure than glifoneri and take note... where what was polished?
Cool!
I stepped back and took on the job shlifanut gear and cover... And still went through dviglo and everything sorted out it was... :(
cool. I came up with when the pump Gur sanded the rotor and the washer in which it rested. And preggos without Gigi traveled, and pogubil pump, all the bullies were. Then while working.
But if after grinding these gears cause the deposition of salts of titanium, they all will be eternal.
the screws still out of the plate, for Subaru common
During Assembly I took welding in any
Great article, just steel Hideki to cogitate, and most likely the fault of the state of this "miracle"
the question is on the engine of the Audi 100 C3 of 2.2 KU and digitale Audi S series with 5цилиндрами pump housings are the same but the gears different number of teeth. So what ratio should be and what it is better to put what the clearance should be and how to raise the oil pressure and how many times can I restore the oil pumps?
bit. but the correct way to increase performance is to replace the profile of the pinion and of the boring of the channel to the heap
what about the bore and the outlet channel, this will help to increase performance?
all series S — chugunin. plus the exhaust manifold at the front — which further worsens the allocation weight of y fragile T23.
I now weight 58-42 — not the worst option.
What attracts? probably Yes — irrationality. the gauntlet has been thrown. This is the only Celica in the world with 2зз-CTU and all-wheel drive on the mechanics.
It looks like it)))) I Just atmosferico only Toyota's 3S-GE impressed 2ZZ-what is plasticine did, though in theory it is cool. And 3S-GE isn't aluminum? Why is he heavy?
Yeah 2ZZ is generally the only one, but I would not say the good side. More zamedlennoi lift system I've ever seen. Nissan was able to gash their SR20VE(T), which in terms of reliability and performance is almost the same from Honda's B18 was no different. Later only)
How is it you find so attractive? Just an irrational feeling?:)
because 3s-GTE logistics, shoved in any car...
because 3s-GTE logistics, I believe the God of motors...
and in fact:
because 3s-GTE logistics, archaic, heavy, mammoth... nothing interesting there. just a 2 liter engine with turbine. the same, such as Cosworth.
And 2зз... one of a kind Toyota.
well, apparently the quality of the gear more )) from Toyota they are powdered metal. I have now are all-metal, machined
Japanese original just crumble (( specifically these motors are driven with a cutoff at 8200 rpm
but not before clipping them crumbles. the resource of a gear is not great
Even the Japanese original comes from bad metal? Just the first time I saw that gear crumbled. Or is there some imbalance of the crankshaft serious has to happen for this?
I read "Find in a pile of trash, more or less living body of an oil pump, and send it to the trash" fell into a stupor :)
:) that is the primary actually do? :) just disassemble and reassemble? :) krasava )
not a fact. pump can cover 300. I saw 1зз, in which 350 pumpkins climbed hand Russian super wizard
So maybe my mileage 250 000 km it is likely to change?))he didn't even poltos to master...just how to introduce that to remove the timing belt again, again laying everything to buy, in short I'm all in Dumka now!
it depends on driving style. oil, etc.
but 1зз they go longer than 2зз, as the revs are limited. tykov 200 roll back without problems
Sergey Hello!Not out of my head that never changed, the pump immediately when the replacement timing(((How much it generally goes for engines 1 zz 2001.in.
Well, Yes, now of course prices are generally PPC, new to find standards price
they are treated to a specific hardness. that is not terribly hot, but quite soft, apparently made especially.
dimensions can be removed. but there are tolerances weave...
and the question in the material and in the handling of the product.
Specifically those in England. Actually I seen these in America and yapii. But... now zenneck slightly humane (
no, I'm repairing your car. and even then, only because of lack of money for highly skilled repair :))
It all depends on the master level) and IMHO there are more cutters (or even better CNC water jet cutting or laser) than tokarki.
The material that known stalyga EN24
Welcome! I wonder if tokarka such gear to make, naturally picking the good stuff?
Some gears that never goes away, most likely wear on the body is already there. It may be easier to buy a new pump?
These gears were restored, not because the fun, and because it initially did not stock gear, they have modified profile teeth, the material is normal and is not the powder for them, and they are expensive
