Honda Engine Oil Leak Repair: [GCV 160 Shaft Seal Replacement] (2019)

[@qman2279]

hey thanks for the video. I plan on using a zip tie around the shaft to prevent the key from riding back up.

[@DIYAllied]

That's a great idea. Cheers to you.

[@Jd77469]

@@DIYAllied what is supposed to hold that key in place? Is there a ring or something to keep shaft down? my key I think damaged my seal by hitting like yours.

[@DIYAllied]

I'm not sure anything actually holds it in place.

[@Jd77469]

@@DIYAllied ok thanks for quick reply I saw this o ring in my garage broken in half and It seemed to fit the bottom of the seal perfectly. I can't find any videos or online information that shows the shaft so I can determine if I'm correct or not. I guess small zip tie would work.

[@Jd77469]

Bottom of the shaft above the key* perfectly

[@Bmanbill5]

Couldn't find any info regarding that shaft seal until this video, still helping us out 6 years later lol thanks

[@DIYAllied]

You are welcome

[@kieranfleming7963]

Thanks for this video, exactly the video I needed. Easier than I thought. I originally thought I would need to take the entire shaft out. Done in 5 minutes!

[@DIYAllied]

No problem. Thanks for watching.

[@simplybeanjelly]

Thank goodness you can get it from the bottom. I was just about to sell a mower when I noticed that the shaft seal was leaking and I went "ah crud!" luckily it's a $6 part and looks to be super easy to fix :)

[@mdcoomer67]

Thank you for the video. My pressure washer has been leaving drips here and there on the garage floor for a year now, and today it started to drip on the pump while I was pressure washing, causing a really nasty smell. Part is on order, and I’m looking forward to not have drips marks on my garage floor now.

[@DIYAllied]

Thanks for commenting. Enjoy your new pump.

[@scottellingson9717]

Thanks for the seal link. My pressure washer key rode up and took out my seal. I plan to use a small hose clamp to hold the seal in place. Seems to be a issue. Also a piece of PVC pipe works to tap the seal in. Or any type of tubing really that is slightly smaller than the OD of the seal.

[@stevemiller4812]

This video was very helpful to me regarding removal of the shaft seal. Saved me about $250 on getting another refurbished pressure washer.

[@DIYAllied]

That's awesome. I'm glad it helped you out. Thanks for commenting too.

[@franktinga6303]

Outstanding video!! Not only showed the fix but described the most likely cause. Again thanks. Short and sweet!

[@DIYAllied]

Thank you so much.

[@DIYAllied]

Thank you very much. I appreciate that. Thanks for commenting.

[@JoeLomba]

Thanks for the video I used an old vacuum cleaner wand for pushing in the new seal to prevent damage

[@DIYAllied]

That's a great idea. Thanks for the tip.

[@DIYAllied]

You are welcome

[@jasonbrowne7057]

Always check with your Honda dealer and reference your engine number to ensure you order the correct seal. Whilst some of the later OHC GCV160 engines use this crankshaft seal, the earlier model GCV160 engines have a 25mm diameter shaft. This seal is for 28mm crankshafts.

[@DIYAllied]

Good advice. Thank you.

[@TheJtg0411]

I know this is an older video but is the seal the same on the gcv190 as on the 160?

[@bsizeyt]

Hi. Helpful video. It looks like I have a damaged seal on the pump side (female receiver for the drive shaft). Will that also cause oil to leak and if so could you help me understand how to replace it. Thanks

[@jayfaircloth7422]

Can u tell me y my troybuilt 160 honda pressure washer started pushing oil from under th fly wheel? It started when I cleaned out the main jet in the carburetor and reassembled it. It ran and washed great for about a minute then oil started running down the engine.

[@DIYAllied]

Not sure on that one. It's tough to diagnos without seeing it. Sounds like a gasket issue to me but I can't say for sure.

[@jayfaircloth7422]

@@DIYAllied how can I send u a video? I'll show u what it's doing.

[@DIYAllied]

@@jayfaircloth7422 if you have a smart phone you could do a video and post it.

[@jayfaircloth7422]

@@DIYAllied I'll do that it's kinda crazy never had this happen before,but anything can happen with an engine i recon

[@biglar155]

Exact same thing happened to the seal on mine. I live in a cold climate so I pull the pump in the fall and store it in the basement to prevent freezing (I keep the motor in the yard-shed). This spring when I put it back together I must not have noticed that the key had ridden up. The first time we used it, it destroyed my seal. (The only reason I shut it down before all the oil was gone was because I was letting my son do the work and I just happened to walk over to the unit and see oil flying.) Your video is particularly helpful since the seal was completely destroyed and I wasn't sure if the metal of the engine had been damaged. Based on the video, I think I'm fine and just need a new seal. Thank You!

[@DIYAllied]

Thank you. Good idea on removing the pump for winter.

[@crazywaderacing4659]

Yes do a video on the crankshaft seal on a GC 190 Honda engine has pressure washer on the rear end Not underneath

[@DIYAllied]

I will if I get the chance to do so. Thanks

[@physiques]

I realize this video has some years behind it but I found it today and I'm generally very handy. I separated the motor and pump and have the motor on my work bench but for the life of me I can't get that seal out. I've chewed it up pretty bad and it's done for sure now. Any tips on what I can do to get it out. Much thanks 👍

[@DIYAllied]

I wish I had some good tips for you but its been awhile since I did that job. I'd say keep at it and best of luck.

[@DIYAllied]

Thanks for commenting and watching. I wish I could be more help. I always appreciate the interaction with viewers.

[@DIYAllied]

@@physiques Awesome. Thanks for the update

[@appleztooranges]

Going to try this. How did you know how far to seat it in? I’m using an old vacuum hose wand to put it in

[@DIYAllied]

It bottoms out pretty obviously. Good luck. Mine is still working.

[@appleztooranges]

@@DIYAllied sweet deal. I have had a small leak from my pressure washer since I got it used about 1.5 years ago. There is no oil coming out of the engine crank shaft though. I disassembled the pump from the engine. I put the pump on a paper towel vertically to see if it leaks down. The engine is now exposed with the crank shaft. I see no leaks on either seals. If I run my finger down the dip stick I feel oil residue. I purchase a new dipstick (Honda oem) as I heard it can be as simple as just this if the old one is defective (probably not though). I’ll give it a week and see which leaks the pump or the crank shaft. I purchased a crank shaft seal anyways in case mine is bad. It’s hard to tell. Only leaks when it’s sitting for long periods of time and not in use 🤷‍♂️

[@DIYAllied]

@@appleztooranges Interesting. I'm curious as to where the leak is. My bet is on the crankshaft. Thanks for commenting.

[@appleztooranges]

@@DIYAllied I wonder if I should try soap at the crank shaft and see if it bubbles. I’m hoping the wand trick from the vacuum will work well. I’d be pissed if I mess it up when seating it. Anyways i bought a new crankshaft seal, new dip stick rod and new pump seal. If that doesn’t fix it I don’t know what will 🤷‍♂️🤔

[@romarioadams1587]

Great video, I have this same problem. however, I can't locate the seal on the manufacturer's site. Could I use this one? I have a Simoniz pressure washer

[@DIYAllied]

If the engine is a Honda gcv 160 yes.

[@PedroHernandez-ue5xf]

Thanks for the video, what's the serial number for seal ring?

[@DIYAllied]

Not sure. I have an affiliate link in the description that will take you to the seal you are looking for.

[@PedroHernandez-ue5xf]

@@DIYAllied ok no problem, I got it from one of the coments, my other question is, is this the same one for a 190 over head cam?

[@DIYAllied]

@@PedroHernandez-ue5xf I can not confirm that the seals are the same or not.

[@DIYAllied]

@@PedroHernandez-ue5xf sorry I'm not much help on this.

[@JustBraap]

You ever had that orange/red colored seal go bad at the top of the pump itself? I've got gray looking oil leaking out from the top of the pump (it runs down the pump when I lean the pressure washer back. I haven't taken the pump off yet but I know for sure the oil is not coming from the seal at the bottom of the engine as that is dry and has no oil coming from there.

[@DIYAllied]

No I have not but it would not surprise me if it has gone bad.

[@alexanderx3554]

Did you ever take the pump putt and diagnose further? I think I have the same issue, the oil is heavier than motor oil and the level stays constant.

[@kevinkruse88]

Thanks for the walkthrough, Ive got a GCV190, looks to be near the same, What oil did you use? I cant seem to find any info on it

[@DIYAllied]

You are welcome. SAE 10w 30 is what I use. This model has a capacity of .58 quarts but I'm not sure on the GCV 190

[@davidannunziata8903]

Are the shaft keys specific to the pressure device or fairly generic?

[@DIYAllied]

They are fairly generic. You should be able to get one at your local hardware store.

[@jaimebermudez4900]

Hi. Great explanation. My shaft key is stuck on the shaft. I have been trying to remove it with WD40, but it is not coming loose Any ideas, before I have to pay someone for the repair?

[@DIYAllied]

I'm sorry for the late reply. I don't remember being notified of your comment. I must have missed it. Did you ever get that shaft key off?

[@jaimebermudez4900]

@@DIYAllied Yes, but the pump is no good. I am looking for a good replacement. Any ideas where to look

I bought mine on Amazon. 60-70 bucks.

Thank you man! Exactly what I was looking for!

[@DIYAllied]

[@mattseymour8637]

How long do these seals normally last on a Honda engine?

[@DIYAllied]

They last a long time. My seal was damaged by the key sliding up the keyway and rubbing on the seal. I'm sure most last 10+ years or the life of the engine if its well cared for.

[@benjaminlozano6371]

Can you talk about oil change in water pump. If need be. Thanks

[@DIYAllied]

Thanks for your comment. I am going to do a video specifically about the pump itself.

[@kevinmatthews9967]

Great video, I need to do the same. Before I order the part using the link you provided, just wanted to ask if your GCV 160 a 5.5 honda motor? Thanks in advance.

[@DIYAllied]

As I understand it Honda dose not designate a specific hp for these engines. It is essentially a 5 hp engine. Hope that helps.

[@sandyharkness6891]

you have to install a collar on the shaft, to prevent the key from riding up. it's a terrible design, and requires after-market thinking.

[@jaimebermudez4900]

Great video. I replaced the seal, but my shaft key is stuck on the shaft side. Have been trying WD40 to get is loose, but it does not come loose. Any solution you can offer? Thanks

[@DIYAllied]

Can you grab a hold of it with a vise grip or something?

[@jaimebermudez4900]

@@DIYAllied Eventually it came off, it took a while. I just did not want to break it. My problem now is that the groove where the key fits on the pump look wider. Thw key does not sit on the groove in the pump. Do I need to replace the pump or is this fixable?

[@DIYAllied]

@@jaimebermudez4900 I would have another pump on hand in case it fails but I would run that pump until it quits. The pump sleeve will give out before the crankshaft for sure.
