3116 Cat fuel filter change

Thee easiest solution for filling batteries is to get an inexpensive pump up garden sprayer, cut the nozzle off and use a heat gun to add a bend near the end, fill with distilled water, pump it up and fill the battery cells....no spills and no danger of overfilling. Sorry, no pictures available since I don't use it now that I have AGM batteries.

Wait....changing to AGM's is an even better solution to filling batteries.
 
Bill Collector!!! I like both of your finds... Yet more items to add to my Amazon list for the boat... Both are PRIME shipping as well... I see a run on no spill gas cans and battery fillers shortly, they owe you a commission!!
 
I ordered my 1 1/4" "no spill" from Amazon last night. It's clear instead of yellow, but I don't think the local gas guys will notice since most of them are self serve anyway.
Now all I need to do is find a nice spot to store it.

I installed a watering kit years ago and love it! It takes me no more than 5 minutes to top off 4 batteries, 2 of them being 128lb Trojan J185H. Unfortunately my batteries are on their last legs so I need to decide between replacing in kind or going to AGM.

Thank you and I can only take credit for battery filler w/auto stop....
 
About to do fuel filters, to pre-fill or not to, jury seems out whether to or not to?.

Question is, “never forget to turn fuel valves off before starting “ what is meant here? which valves specifically?

You have a panel somewhere that selects which fuel tank each engine burns and returns fuel to. One option on that panel should be OFF. That prevents fuel from running out while the filter is off. You owners manual should detail the location.

As for pre-filling, 3 schools of thought.

- First, use the on engine primer pump. This is the book answer, but in practice, these pumps can be very messy.

- Second is pre-fill the filter using clean fuel. The downside of this is if done improperly or with contaminated fuel could lead to injector issues.

- Third is to advance the throttle to 1/2 and crank til the engine fires, then idle. This utilizes the on engine lift pump to fill the filter.

For the record, I'm a on engine primer pump guy. Those pumps do deteriorate, leak, drip and make a mess after a while. I easily repalced one this year, and that solved the issue. Works like a champ now. Here is the thread on changing that pump.

One answer, the one above is referring to the ball valve that is right on the priming pump itself. It is a little knurled plastic "thingy" that serves only to open the fuel flow to the priming pump.

The other answer referred to the main fuel valve on the Racor housing, and it just opens and closes the fuel flow to that filter.

There is another fuel valve, if your boat is equipped with the optional fuel manifold, behind the cockpit step on the port side as you enter or exit the cockpit from the side deck.

The one to pay attention to if you are priming the secondary filters after changing them is the first one mentioned above ("never forget to turn the valves off before starting").

There is a gotcha using the little ball valve on the priming pump: The knob is a round plastic affair that is pressed on the pump shaft. When used for several years, it is easy to dislodge the knob on the shaft to the point where you cannot tell if the valve is on or off and you leave it open or even partially open, the priming pump will siphon raw diesel into the pump where it will leak all over the bilge. The rings in the pump are intended to by dry except when priming so th e pump will not hold fuel but will leak around its shaft.

This is the only poorly designed thing I have discovered on Caterpillar engines. I prefer not to add an hour or more to my filter change just to clean up the mess the Cat pump makes, so even thought Cat recommends using the priming pump and not pre-filling the filters, I prefer to profile mine.......but, our fuel delivery pumps are filtered to 2 microns and are treated with stabilizer and Valvetech stabilizer and refilling the filters is safe and more productive than using the Cat priming pumps.

Thanks guys. Was always intending to close off at Racor’s. The small plastic tap thing on the primer pump answers the question. Will investigate the quality of the diesel at the marina and see if it’s okay to use for purpose of filling filters. Prefer that method versus risking the deterioration further of the primers. Hoping to get to servicing Racors, engine fuel filters and cleaning of the sea strainers this weekend.
 
On the boat today doings the Racors, all good.
Was surprised to learn that the oil and fuel filters on both engines are different Cat product #’s.
Port side 1R-0750 fuel and 1R-1807 oil. On the stbd engine, 1R-0751 fuel and 324-2598 oil. Why do the same engines have different model filters for each?
I can see the difference in the fuel filters being different thread size, and with the oil the difference is in the length. Does this have to do with where on the engines they are located as the port engine have them on the stbd side of it and the stbd engine have mounted on the port side, I guess for ease of changing.
 
I don’t think so in this case, current filters are only a year old so all are current models.They are physically different in size and thread size. Fuel have different thread size but same length. With the oil filters, the length are massively different. I am thinking it all comes down to where they are set up on the engine. Just interesting, the two fuel have different threads and the two oil have different capacity.
 
The longer one is the “high efficiency” oil filter. Fits fine on the starboard engine. It won’t fit on the port engine do you must use the shorter standard oil filter.

Last fall I bought high efficiency filters and struggled with the port side until I realized the difference. Got a standard filter and it took only a few seconds to put in.

Your boat left the palm coast factory with the same fuel and same oil filters on the port and stbd engines. I've known that boat since about 2000 and I don't think either owner had need to change either engine while they owned it.

i was shooting from the hip and it was happy hour.... sorry the bad info but I could sworn they changed the part number several years ago....

BC I think you are correct. I ran into that when I bought mine.
 
That would certainly make sense Steve re the oil filters as the high efficiency certainly won’t fit on the port side.
Pretty sure no engine change either Frank, as you know she came to NZ around 08 and Steve certainly hadn’t changed engines. Maybe at some stage in her life the fuel fitting where the filter screws into had a change out and the new one had a different thread size. Just strange to have identical engines and completely different engine filter sizes. Regardless, they are doing the job, so will stay with them.
 
I'm going to change my Cat 3116 filters this weekend and just want to confirm approach:

Use the Cat primer pump (I know one of mine leaks)
or
Prefill from a jug and start with full throttles to clear any air (risk of contaminated fuel if not filtered)

I just want to confirm there isn't also an option to start full throttles with a dry filter. Some of the comments are unclear.
