[C320-list] Perkins motor oil filler

[Bob Borelli]

Changing oil & filter on Perkins M30 is straight forward, not difficult, after its been done a few times.
I have to locate the intial email with the attached picture with the A,B,C labels.
It was a good question with several very good answers back in late January this year 2021.


I use the second method to hand pump the oil out of my Perkins M30.

A is the coolant drain, a 1/4" ID vinyl tube fits over the nipple to drain coolant into container.
B is the tube I use to pump out the used, warm oil from the oil pan, annual oil change, using a threaded barbed fitting.
C is a lube oil tube from the cylinder block to the cylinder head.

I tried pumping oil from the dip stick, also slide tube down dip stick, no success.
So I remove the old oil from B.

I remove the old oil filter first to allow for room.
Then I remove the Cap Nut on B with a 7/16" open end wrench.
Then I screw in a 3/8"x 1/4" Adaptor Barb MIP purchased at Home Depot.
A 3/8" ID vinyl tube is attached to Barb and other end to a PAR Handy Boy hand pump.
A fast, clean oil change!
Re-install Cap Nut, add new Fram PH2951 filter & Shell Rotella T1 SAE 30 Heavy Duty Diesel Engine Oil.

What oil & filter are you guys using on your Perkins M30?

There is also an oil drain plug on the aft end of the pan, under the oil filter, reachable with a socket but how to catch the old oil without a mess.
I use oil absorbant cloths from Amazon Prime.   Plastic gloves, 13 gal plastic trash bags, blue Shop Towels & Spray Nine Marine cleaner.

David;

You are correct.  If you open each cap, you will find that the metal cap opens just like the radiator cap on a car - you need to push down while turning (on a cold engine only!).  You should be able to stick your finger into that opening and see/feel coolant.  This should be a regular prestart check on your engine right along with checking oil level.  I don’t trust just looking at the level of coolant in the overflow container.

The black cap on the left is the oil fill.  When filling your oil, put in only as much as you got out and then start checking oil level on the dip stick and slowly add small amounts until you get to the safe level marking on the dip stick.  It isn’t good for the engine to run with too much oil.  Pre-fill the oil filter with a little clean oil before spinning it on and smear a little on the O-ring on the filter, but you can’t fill it completely as you have to turn it horizontal to screw it on.
