My mechanic told me if i remove my diesel pump then i will alter the timing of the pump is this true?
Answers:
Yes, the pump is driven by the engine. The injector (diesel) pump has to deliver the fuel to the cylinder at the correct time. If you remove the pump you will disturb that timing, turning the pump even a little bit when separated from the engine will cause the engine to run badly, or not even start. It takes a certain amount of skill and specialist tools to re time the pump to the engine.
Best left alone unless you have the skill.
Yup , it's true.
pump timing is the key to power,you can reset it
no
yes it is if you dont put it back exactly right you will have quite a few problems i have a diesal van and im quite knowledgable with petrol but diesal it goes to the mechanic just does not pay to mess yourself.
hell yes keep your fingers out
yes it is true of most diesels that you will need to set up the pump timing if you remove the pump as it is turned by the timing belt and it is the mechanism inside the pump that delivers the fuel to the correct cylinder at the correct time - but on more and more modern diesels that are switching to the common rail system of fuelling - they work similar to a petrol with a low pressure pump in the tank and a high pressure one turned by the engine - these just build up pressure but the timing and the delivery are controlled by an ecu - so if your car is an older model he is right if its newer he may not be
What he meant was that if you remove the pump it will have to be re- timed when fitted back. removing it does not damage it
Yes. This is where every mechanic in the world has a very useful timing tool in their toolboxes. It's called Tippex. Works wonders.
yes only remove if you have the correct timing tools and positions to reset it because if you dont and try to bodge it you use more fuel and alter co2 readings etc
use a specialist Diesel service mechanic. Fuel pumps are not to be fiddled with unless you have the tools and experience to set them up properly. I do fuel pumps for ship's engines as part of my job.
