I didn't know they would service the generator. For $50 I will let them do mine next time also. Camping World charges $99 for just Oil and Oil Filter. They wanted another $80 for the fuel filter change. Filter is $14 at Advance Auto, and it should take about 5 to 10 minutes depending on familiarity.

Onan left us a lot of extra hose for a reason.

1. Remove the center nut that holds the filter to the bracket. A standard ratchet works fine for this.
2. After the nut is removed, Push the filter toward the rear of the generator about 2-3 inches. This is why the hoses were left so long!
3. Swing the lower hose toward the engine so it will clear the bracket, and then raise it up and rest it on the top of the bracket.
4. Now that both hoses are on top of the bracket, simply pull the filter back to the front and hang it outside the enclosure were you can easily work on it.
5. From there, just follow your normal procedure for swapping the filter and then reverse the instructions to re-install.

It took about 60 seconds to get the filter out of the enclosure.

I hope this helps as you guys have helped me on numerous occasions.

I agree with the long hose comment Dennis however I changed my filter recently and went about it in a little different manner which worked great for me. I didn't find this a difficult process at all. I used standard open end wrenches:
1. Remove the rigid metal fuel line closest to the engine block from the filter.
2. loosen the center mounting nut
3. rotate the fuel filter 45 degrees or so towards the engine thus exposing the other fuel filter fitting with the attached flexible rubber fuel line.
4. Remove the rubber fuel line from the fuel filter fitting.
5. Remove the fuel filter center mounting nut and remove the old filter.
5. Reverse the process for installation :dance:

I also thought replacing the air filter was pretty easy. Just remove the three screws in the generator top housing panel and move the coolant reservoir assembly to the side to access the air filter.

I published my take on Dennis' method in another thread a little while back...I believe this is the best method. No special tools, minimal fuel spillage occurs, all of it outside of the cabinet (no messy fuel inside to mop up, just put a pan under it once the filter is outboard) and it takes about five minutes.


edit: pull the dipstick out before you try to remove the filter from the cabinet, makes it easier...

I agree on the air filter. A lot of people have commented that getting to the air filter was difficult or required removal of brackets, and then was still difficult. Just as you did, I just removed the three bolts that hold the reservoir, slipped it out the side and let it hang, then reached right in for the air filter. No problem.

DITTO on the air filter. Took all but 5 minutes to change once I read this post. NOW THE FUEL FILTER....DIFFERENT STORY. After cutting 2 knuckles and a few choice words, I decided to wait on my friend to get back from a long weekend to tackle that part. He works maintenance at one of the nearby plants and is good working in close quarters. I did find it though. Seems that there should be an access hatch to make job easier. But then again has any designer ever considered the consumer side of things. Thanks guys for all the knowledge shared on this site.

Speedco , in Salt Lake City area would not change the fuel filter on my 2016 Aspire 10K Onan. They did all other filters, oil change etc. $60. They started on the fuel and then they claimed because of having to remove the panel for access they were not authorized to continue with the fuel filter change. ? I then called Cummins while it was still on the rack and they said many shops will not do that one and suggested to take it to a Cummins shop. It didn't look like something I wanted to do.

Are we all talking about the fuel filter on the same gen. RV QD. HDKCA 10K ? If so, I'll take a closer look.Thank's

I had the HDKCA in an 07 Monaco Exec. There are two bolts on the outside of the compartment or case right next to where the filter is located. Remove both (10mm I think). Pull the filter outside of the door-the lines are long enough. Change the filter, slip it back inside and re install the bracket bolts. It's MUCH easier to do it outside the case. Good luck.

I have a question which is not fuel filter related. Wy question where is the location of the spar arrestor plug? An shouldn't that be pulled and the genny run under a load for about 15 minutes to clean the soot out? I will be servicing mine in a couple of weeks. Thanks

royals1212 08-08-2016 03:01 PM
Found the answer for the clean spark arrestor, every 250 hours. The location on the HDKCA(10k) and the HDKCB (12.5k) is under the top cover. The 11/16 inch hex head plug is located on the opposite side from the servicing door.

QD 10000 Fuel Filter Change

This is the way.

Fuel filter change takes about 15 minutes including leak check and reassembly. Will be faster with practice and knowing which tools to have ready.

Fuel filter retaining nut: 1/2” socket at ratchet. Just move the flexible lines up and out of the way to get clear access to the nut.

Large fuel line: 5/8” and 11/16” standard wrenches
Small fuel line: 7/16” and 9/16” standard wrenches

Oil plug (in case you’re doing that too): 7/8” standard socket

Prime the new filter for 30 seconds, then proceed with regular start. I primed and ran the genie for a couple minutes to check for leaks before reinstalling inside the cabinet. Then ran it again to make sure the lines didn’t get loose during reassembly.

Picture is worth a 1000 words.

Thanks

I know this is a old thread......................

Thanks everyone! They sure did bury that filter. I looked right at it and didn't see it behind the bracket.

Used the "Dennis" proceedure, took about 20 mins.

Thanks again!

Just hope that you never have to change the fuel pump. The Onan provided cover plate is blocked by the tray slides which means removal of the generator.
