Best gx390 rebuild video. I rebuilt motor following your assembly and disassembly videos and saved 400 in labor 😊 Thank you!
I wish the ones I take apart look anything as good as those 😂
Well we did start with new and it has never been on anything to make it work. Ya I wish they were always that clean, lol
Fantastic, Crystal clear video. Thank you!
Thank you for your time of the instructions very helpful , blessings
I just bought a new block from honda for my 390
Thanks I have a low oil sensor bad on a GX390 which I disconnected so engine will run. To much work to replace ,thanks for showing it internal inside engine
Great explanation thank you
well explained thanks for sharing
Que buen motor ,,,es honda no hay con que darle
This is really cool
Thank you very much big man thank you for your nice tutorial 👍 I really appreciate you sharing your great knowledge.
I've used this sprayer several times now on brick pavers, a wood deck, patio, and a driveway. czcams.com/users/postUgkx43QMbQqu67IZadu9ou8Sg1BdrunMRNqX It has performed as expected on all surfaces. For larger areas like the decks and patios, I think I will be looking into a surface cleaner attachment to speed up the job, or at least make it a little easier. Hose and sprayer connections are tool-less, tight, and quick. I used the yellow nozzle on the concrete/brick surfaces, and the pressure was adequate for cleaning those surfaces.I am disappointed that these units are still being shipped with a nozzle storage holder that allows them to vibrate out of the holder way too easily and become lost, but I don't want to knock off a star for that reason. The functional part of the washer works very well, so I would recommend this product.
Nice job.
Good video
Thanks
I was wondering why so much heat was coming out of the side of our engine. You're video explaining the fan pushing air through to help cool the block makes total sense. I thought a gasket might have blown.
All engines produce heat because of combustion. The harder you work an engine the more heat it will produce. You will either have an air cooled, fan cooled (like this one) or a liquid cooled system. These three are the most common. A cooling system is vital to prevent damage from overheating.
@@jtkasprick We have a 390 on an EastonMade 12-22 firewood splitter. Early model, the newer one's have fan coolers on them.
Very informative. Thank you. Was that residual oil still left in the bottom of the case after draining?
Yes it was
I have set up my trailer so that it’s difficult to change the oil on the gx390. Would a suction oil extractor be efficient? Is there access to the bottom of the pan from the dipstick? Just want to make sure I don’t leave too much residue behind at the bottom by not using the drain plug
A suction extractor may work. But you are right to think it may not get it all. The dipstick opening goes straight to the bottom of the sump (pan).
very nice video...I have a issue I hope you can help me with. I have a Honda GX390 on a generator. I replaced the crankcase shaft oil seal as it was leaking. I installed in flush with the engine case. After running for awhile it started leaking again. I thought the seal needed to be counter sunk a bit so I replaced it again. And after running for a short time it has started leaking again. Im not sure where to go from here. Both times replacing the seal I used steelwool to clean the shaft and it seems smooth with no defects. Any advice would be great! Thanks in advance
I was thinking maybe you have excess crankcase pressure. I was going to do a video on this but haven't had time. There is a passage that goes from the crankcase along the cylinder and into the cylinder head. When the piston is traveling down it will increase the crankcase pressure. When it travels up it will decrease the pressure. The passage allows outside air to move in and out of the crankcase. Similar to a PCV system on a vehicle engine. If you take the valve cover off you should see a small round hole near the valves, not where the pushrods go. Closer to the top. If you pull the engine over you should feel air coming out as the piston moves. If it is plugged this could cause increase in pressure and force oil out of the seal.
Español ? Subtitulos o traduccion ? Por favor gracias 👏🏻👏🏻👏🏻
hi what size and model and brand is 3 jaw puller. if you are using snap on or OTC pls do provide me the 3 jaw puller name and model
Any difference in the black shrouded GX 390s ? Looking at a woodsplitter with one on it...thx
I think they are the same.
Great video and explanation. How can I send you a PM on information on your sponge organizer for nuts & bolts.😀
Email me at jtkasprick@gmail.com. it is 3d printed. I have the file if you would like it.
I watched this movie well.
I have one question.
After removing the flywheel, there is no charging coil???😊
This engine does not have a charging coil.
Could you leave all the flywheel etc fitted if you need to inspect the tappets/crank?
You could. The flywheel would have to come off if you were removing the crankshaft.
@@jtkasprick cheers mate 👍 my generator started ticking after long use in the heat and looks to be burnt around the exhaust valve in the valve cover 😭
You don't need a puller to remove these flywheels, just put the nut level with the thread end and then one solid tap with a lump hammer will remove it.
I will give that a try. We teach using pullers so our nubies know what they are and how to use them.
@@jtkasprick Great, hope it helps, I only work on new engines, but I've probably removed 5000 flywheels like this over the years.
hello i have 11 hp engine i have two yellow wires coming from carburetor! where should i connect them?
What is the model number? Is it a gx?
@@jtkasprick modelini bilmiyorum jenaratörden çıkma motor
What is the final rpm of this machine after the gear transmission?
I believe the reduction ratio is 6:1. 6 revolutions of the crankshaft would result in 1 revolution of the PTO
The cam shaft won’t come out for me what do I do?
There are no bearings supporting the cam. It is the cam journals in the aluminum case and front cover. Did you loosen the valve adjustment nuts to remove any tension on the valve train?
Do you happen to know if Honda has an electric start kit for a 2012 or later Honda GX390. All the kits I have found online (Amazon, Ebay, etc.) are for a 2011 or earlier model year. I know Honda currently offers versions of the GX390 with electric start, but cannot for the life of me find a kit for one that didn't come with from the factory. I know the flywheel and I believe the coil is different on the 2012 and later models. SO FRUSTRATING!!!!
Sorry I can't help. I have never actually looked for a kit.
@@jtkasprick Dang! Thank you for responding so quickly.
re coil hard to pull on my Honda GX 390 8 GPM pressure washer only 7 mos. old
There is a decompression valve located on the rear of the camshaft on the exhaust lobe. It lowers compression pressure for starting. Maybe it is not working properly.
Are you holding the trigger open on pressure gun? Once the pump builds up pressure in the hose, that engine will feel locked.
giveaway?🙂
Unfortunately no.
What causes Gx390 to swallow fuel
Are you meaning using an excessive amount of fuel?
Yes excessive amount of fuel..
I am assuming no external leaks. Is it running rich?
What are you using it for?
Your entire video so far is soundless. Like one of those old talkies. Not even muzak.
