Oil pump is an oil pumping device that is mounted via gear (gear ratio) to the crankshaft. It place inside oil kept tank (bottom plate) through oil is been suck in to the engine.

Ankush said: (Feb 11, 2015)  
Yes and its discharge is quite high.

Swadesh Shukla said: (Apr 14, 2015)  
But first option is true because some engine oil pump is driven by camshaft screw gear both option A and D is also true.

Kasim said: (Oct 10, 2015)  
In both of them which is right either A or D.

Suganth said: (Dec 23, 2015)  
In conventional they use camshafts. Option A.

Jayadeep said: (May 18, 2016)  
I think both A & D.

Oil pump is driven by a camshaft using a helical gear.

Khushi said: (Jul 14, 2016)  
Oil pump is driven by a camshaft.

Aishwarya K D. said: (Dec 1, 2016)  
It's A & D both.

But which answer is right? Tell me one.

Kaushik said: (Mar 12, 2017)  
According to me, camshaft is correct option.

Rahul Kumar Verma said: (Mar 29, 2017)  
I think Both A and D.

Because some engine's oil pump driven By cam shaft.

Naveen said: (Mar 31, 2017)  
I have seen many of the old vehicle in ic engine oil pump connected to the cam shaft.

Now a day it connected to cam shaft timing gear.

Anil Premi said: (Apr 27, 2017)  
Old vehicle was driven by the camshaft and new vehicle gives by crankshaft. So I think A is the right answer.

Natarajan said: (Aug 3, 2017)  
Oil pumps drive only camshaft.

Anbarasu said: (Sep 19, 2017)  
Camshaft skew gear drive the oil pump.

Oomban said: (Oct 3, 2017)  
Distributor and oil pump driven by helical gear of cam shaft.

Saurabh Thakur said: (Oct 28, 2017)  
In heavy vehicles it is driven by the cam shaft.

Vinder Singh said: (Nov 4, 2017)  
Its driven by camshaft skew gear.

Sanaullah said: (Feb 15, 2018)  
In above question there is no clear either it a engine oil pump or fuel pump. Engine oil pump is drive by crank shaft and fuel pump is drive by cam shaft.

Akki said: (Feb 18, 2018)  
Yes, right actually fuel pump gear mesh to camshaft gear.

Biswajeet said: (Feb 25, 2018)  
Oil pump are driven by different part either its crank or cam design by the manufacture.

Most of manufacture take option of crankshaft drive cause its reduction and weight.

And most of oil pressure required for the crankshaft.

Rawlings said: (Mar 4, 2018)  
The oil pump is responsible for conveying the oil for engine lubrication and building up the oil pressure in the lubrication system.

Oil pumps are usually operated by the crankshaft by way of auxiliary drives. The delivery of the oil pump is governed by its size, speed and design.

Oil pump is driven by the cam shaft.

Yogesh said: (Apr 29, 2018)  
Crank shaft driven by cam shaft, and cam shaft driven by oil pump.

Arun said: (Jul 4, 2019)  
This answer is not correct because some oil pumps are also driven by the camshaft.

Samir Kumar Panda said: (Aug 23, 2019)  
Oil pump is driven by a cam shaft (also oil pump driven by a crank shaft through camshaft). So, camshaft is the correct answer only.

Vineeshkumar said: (Nov 18, 2019)  
Oil pumps are usually either inside the oil pan and driven by a camshaft or outside the pan and driven by a crankshaft.

Hitesh said: (May 25, 2020)  
Crankshaft is the correct answer.
