Chain Oiler quit oiling

Disassembled Dewalt DCCS620P1 20V chainsaw by splitting cases to get to nonfunctional oiler & replaced same. Somewhat tedious to get to oiler but within the abilities of anyone with reasonable repair skills. Bit of advice. If you use your Dewalt Chainsaw a lot, as I previously have, buy 2 of the oilers. This will be the 2nd oiler I ha ve replaced in my saw. I\'m sure I use my saw more then the average homeowner that caused some of the failure rate.

Chain saw bar not getting oil.

Stanley from NEW CARLISLE, Ohio

Disassembled saw and found the oil pump was for an older De Walt dccs670 saw.
I also have an older dccs670 so I will keep the pump.
I have found no one including De Walt has the parts breakdown for the newer saw.
I also found the real problem was a pin on the rotor housing was broken off.
This pin fit against a cam on the oil pump and the pump to go in and out as it turned.
I replaced the pin by treading a drilled hole in the housing to screw in a #6 screw that I cut and ground to match the original pin.
Although this solution was cheap,
I am unhappy with De Walt for not having information on the newer saw. The correct solution would have been the replacement of correct rotor assembly.
