clean oil pump

[_gonbau]

I plan to flush the oil pump. I did not intend to disassemble it and I intend to proceed to mount the pump in a bucket. The nipple in contact with oil and hit the shaft with a drill attached to a rubber hose so as not to damage anything. I know the direction in which the pump should turn since when turning with the hand it makes suction by the pacifier. I think to give it an extremely slow speed and I also need to verify why another hole enters oil... My question is if someone has cleaned the oil pump, and if this method could damage something? I know that the pump is not usually reused in these cases but in the same way I want to see if it keeps particles inside etc...

It's a critical piece of the engine. I'd send it to Glenn Yee for rebuilding if you have any doubts about the function. You risk everything otherwise.

Since your crank broke and who knows what went through the engine, I would disassemble it, inspect and make sure it’s not damaged inside. The pumps aren’t complicated to rebuild. There was a reason the crank broke. It might have been an oil system failure. So you need to open up everything to make sure all the parts of your engine are working properly, not just that the surfaces are clean.
Before you reassemble the engine, every piece of the engine is it’s own project. Go through it step by step and don’t cut any corners.

Yes I know. I've been following his threads. But if metal went through the pump gears (which I'm sure it has), you never know what has happened to the ability of the pump to generate pressure. Hence the suggestion unless he can test pressure himself. FedEx and UPS both operate in the Canary Islands.

I have opened it today. I have found no trace of metal particles or damage. I have run my fingers along the edges of the "pinions" to see if they had the same damage as the intermediate shaft, no, these are smooth and without deformation! My interest in the oil circuit... when I disassembled the filter (I cracked it the other day) I found metal particles on the fins (the external part) on the internal part I found no trace impregnated in the cardboard... Seeing the size of the particles I would like to ask again... Is it normal for the particles to go through the filter? I understand the damage to the intermediate shaft when it fractured, pieces fell directly into it, but why haven't I seen more damage? If the breakage produced "chips" why didn't the pump suck them directly? But if the filter? How can the oil pump sprockets not be damaged but there is dirt in the filter? I have to better check the oil circuit in these engines but it still amazes me how hard they are... My father drove several kilometers with the vehicle in this state... Regarding the breakage I think the pump had nothing to do with it! YES a double in the tubes of the oil circuit (but I don't know if that could cause this) Rather I think that the fault has to do with the valve that touched the piston! I think so.

I will investigate the oil pressure and I will try to see if there are workshops available around here, if it is not the case I will study to send it to review but what costs? If the "new" pump costs around €800...
and what island are you on? We are experiencing a "big" fire right now... Nothing compared to what is happening there but for the "canaries" it is somewhat complicated!
And by the way, I've said it several times, if any Tenerife catches you on the way on a trip or you pass through here, you are invited to see "the junk" ... I'm a message away in that case!

I'll keep it in mind!

I have noticed that the pinions have respective "marks" on the outside of one...on the inside of the other...However, mark the axes on the outside of the pump with a "pen" and when disassembling on the part of the pine nuts.



By the way, I did the test of the idea that it said... The hose works fine. I still need to buy a bottle of suitable oil to carry out the cleaning. Once clean, I would like to "leave" it running for a while with a drill. Will there be a problem with it if I ensure that it has constant oil? Or does the pump need a "pressurized" circuit to function properly? I suppose that for those who understand "oil pumps" my words sound "bizarre" but I would like to clarify those doubts about the circuit and the oil pump.
For now, I have made it work at zero "speed" while adding "3 in 1" to lubricate it....Normal sound and fastening by the pacifier...How much?...I don't know that
