Perkins 3 cylinder pump rebuild

How to rebuild and time a Perkins 3 cylinder diesel pump..

[@corvairist]

Thanks for explaining how to set the timing mark. It was a mystery till you explained it.

Thanks for your help my friend. From Argentina.

[@anatolymelnichuk5846]

Thank you for your careful approach to information. Thank you for your diligent explanation.

Glad it was helpful!

[@randallrougeau530]

I saw the part that I needed to see,, thank you

[@johngoodman1356]

Great job thank you so much. I wish I would have had that information 10 years ago I put it together wrong and it tried to run away on me luckily I had my hose clamps handy. I finally got a hold of a guy named Leon that worked at a port in Alabama and he explained the same way you did. It was very helpful thank you! The reason I'm here is it's time to replace the seals again and I forgot what I did 10 years ago.

[@randallhorner5970]

Where did you get you seals or rebuild kit from, thanks for any information you can supply me.

[@grangersgarage5606]

We just cleaned this one up it had been setting for a couple years . Didn't have to replace anything

[@James-qc9gh]

Thanks for sharing your knowledge. I just finished reassembly of my pump and everything is working properly. Now I’ll install it to see if I have injector issues.

[@randallhorner5970]

Did you buy a rebuild kit for your pump and if so where, mine is leaking.

[@James-qc9gh]

@@randallhorner5970 i didn’t buy anything but parts cleaner. Mine was stuck from sitting, so I disassembled, cleaned and reassembled. It worked great. Yours might have bad or torn o rings.

[@randallhorner5970]

Thanks for the comeback , i feel a o-ring is the problem also, i just thought a kit was available but could not find one. Thank you.

[@James-qc9gh]

@@randallhorner5970 my recommendation is to disassemble it and measure or bring in your o rings and get replacements. Mine were fine or I would give you the size.

[@randallhorner5970]

@@James-qc9gh Thanks i will

[@rubenshartman]

Thank you, sir you just save me thousands

[@terryschramm9904]

Thanks sir. If not for you I wouldn’t have got this pump back together.

[@mathewblankenship7837]

My perkins 300d has a pump like this and one of the o rings had that rod in a bind that caused my engine to over rev and run away, my dad had to shut the fuel off at the water separator bowl...

[@phil-fr4lg]

I have the Shibaura N843 injector pump and can not find the rebuilder's kit. ??? Great instruction video!

[@PreacherDan]

Do the shibaura injection pumps come apart like this?

[@lucaspolley3085]

Thank you for the video

[@kaiser493]

Is there a spring or something when removing this pump?

[@aldoaguirre1244]

be careful make sure if the fuel hole is in the right place I install my pump this way and it cause for my engine to ran away luckily I was able to shut it off the way I fix it was I install the injection pump plunger the opposite way

[@michaelforbes5853]

Can you please explain this further?

[@StephenBrewer89]

I have a Perkins 3 cylinder with similar pump, was running fine, then I let it sit a while and got a no start. Bled the fuel at the injectors and got it going. At again for a couple months and now I can’t get any fuel to bleed from injectors. I am getting fuel to the pump via lift pump. All 3 cylinders dead at same time. What would cause this issue? And I checked the fuel shut off solenoid, it is working.

[@tommasotraverso4961]

Hi, is it possible a leak from the plate hold from the pentagonal screws? Is it difficult to take it out with the right tools? Is it similar to a kubota pump or very different?

[@randallhorner5970]

Where do I buy a rebuild kit, Mine is leaking on the outside of engine. Thanks for any information you can give me.

[@PreacherDan]

So how do you remove the cylinders that have the five sided nuts?

[@josephdeak2257]

Thank you

[@bharrmann4807]

Great video. Getting diesel in my engine sump so going try the rebuild. Does the cam running the pump run in diesel or should it be the engine oil. Sounds stupid but Someine mentioned something pumps run in the diesel....can’t imagine this.

[@claychevyfantinman3585]

It is oiled by the oil in the engine

[@Viatalatara765]

Nice video,how did you take it out and put it back? Thx

[@grangersgarage5606]

We had the engine out of the tractor to do a top end rebuild which made this easy to remove .

[@MichaelAldridge-j7g]

Can i just replace the O-rings, without taking it off the motor

[@calvinconnelly3481]

Did you repair the pump cause you had fuel in the oil or? Cause I have the N844 and trying to figure out if I can do the rebuild my self cause some people told me that I had to retime that pump with some special tools?

[@grangersgarage5606]

I had to rebuild due to the motor sitting for a couple years and it seized the pump and I wasn't getting fuel. No special tools, but the bolts holding it on are a little different on mine but I managed to get them off without any Special tools .

[@calvinconnelly3481]

@@grangersgarage5606 okay perfect thanks.

[@Viatalatara765]

Someone told me,I should be careful when I take it out,because if I don't know how to put it back..won't start..it s that right?

[@grangersgarage5606]

If you take it apart and it's not timed correctly. That is correct .

[@James-qc9gh]

How could the injection pump be out of time since it runs off the camshaft?

[@Xceller8r]

His talkin about being in time with the metering/shut off rack (the part that he was sliding left to right) and the pinion gear (he also took that out). The pinion gear twists the plunger/pistons helical cut - the cuts at the tip of The plunger towards or away from the fuel inlet orifice inside the pumps cylinder. When the slot is turned and opens towards the fuel inlet orific then the fuel will bypass and won’t be pressurized by the plunger thus cutting fuel and cutting ur engines.. the less opening is allowed over the orifice the more fuel is is pressurized by plunger and the higher the engine will rev. Very important to have the rack and the pinion gear timed otherwise the slot on the plunger won’t close/open in the correct position over the orifice based on where the rack position is.

[@Xceller8r]

Also another thing, your plunger can be installed 180 degrees out too in which case the helical cut on the plunger is nowhere near the oriface - which will mean ur pump will be putting out full maximum fuel regardless of where the throttle is set - I did this when I first reassembled my pump and I had a run away - lucky I was able to kill the engine by choking it with a rag over the air inlet

[@James-qc9gh]

@@Xceller8r thanks for explaining. The one who make the video did an amazing job of explaining the alignment of the gear and the plunger therefore I was able to avoid those issues without understanding exactly how the system works.

[@jdhollis4007]

I need to know how to take it off the tractor
