I've never taken apart a twin but I have opened a Quantum. Very little room for the push rod to reside without interfering with something that moves; crankshaft, governor, & camshaft. If the rod is out of harm's way maybe it will be okay but there is always the chance it will move around on a bumpy lawn so I think I would get it out (big job!). Curious what DW6 will say; his skill & knowledge are off the charts.
I had a Kubota lawn tractor with a Kawasaki twin dropped a push rod at 171 hours. I discovered it when it didn't have enough power to run the deck. Tighten up and adjusted lash and now is a good mower. Good catch!
A completed repair includes leaving a steel pushrod rolling around in the oil sump? I am fully aware what is required to retrieve it, but what is the risk leaving it behind? Great find with almost no outlay.............
Stopped video at 12:05. Can tell from the exhaust pulses that there is either a plug or valve issue; I would suspect the later. Looking at some of the comments, I see the valves were the issue.
Worked on the same engine on a mower last fall for customer. Bent intake push rod and it swallowed the exhaust push rod. Blown head gaskets, etc. Engine overheating was the cause. Dirtiest cooling fins and block I have ever seen. Got it repaired and it is still running with exhaust push rod in the sump.
When a kid flips the mower on a hill that loose pushrod might get stuck somewhere it shouldn't be. I've already seen a hole in a mower's piston, kid flipped mower let all the oil drain out then continued mowing once he got mower upright.
Would you sell that to a customer with a loose steel pushrod in the crankcase sump? Good thing it’s magnetic & not the aluminum intake rod… Assume that the oil return passage isn’t blocked by the loose rod, or you’d have seen the end & fished it out with a magnet.
You only have to set the park brake for it to start. What won’t engage is the PTO if the seat safety is not depressed (by sitting on the machine). I still don’t know why the engine bogged down when he wasn’t sitting on the unit when he tried to engage the PTO. Maybe the electrical load on the engine with a charging battery and only one firing cylinder caused the lowered RPMs.
@@johnrazor8720 yes John we all know to start the engine all you have to do is put the parking brake on but to run the PTO you must be sitting on the seat The issue with one cylinder only running would not cause the deck to not run.
When the decks off, I like to take a putty knife and scrape all the caked on grass off off the deck and blades. The owner who junked it is definitely not mechanically inclined. That’s just too funny.
With 55-60 PSI that would be about right because of compression release. But that went straight to 60 PSI which is odd. Since the valves weren't working, it would indicate a problem. A good fix. I just wonder if the push rod is in the oil pan, it could create a problem. Maybe.
I was hoping your video would be able to help me. For a second I thought it would. I have an electrical problem when I turn the key I don't even get the hour meter to light up. Battery is good. Ignition switch is good. emergency seat switch seems to be fine as well. The power lines to the headlights are severed. Any ideas on what else to troubleshoot?
Mine doesn't crank at all, it's not that old. It's a 2019 Yth24v54. I've replaced the key switch, seat switch and nothing. Battery is good. One day I tried cranking it and it started, two days later it didn't start again. Makes me think a wire is not making contact somewhere.
Exact issue I had with my 2009 Husqvarna 2348LS!! Found the problem doing the same sequence of trouble shooting. Will keeping the engine degreased/ clean reduce the engine temp enough to avoid further push rod issues?
Keep it clean will help avoid over heating which can cause head gasket, and valve problems. A good idea to check valve clearance once a year, may not need to be readjusted every year, just good to know.
Hey Mr. DW6, I have a 2 year old Husqvarna 54" mower. It has two problems: (1) It has this habit of running fine then all of a sudden you turn the key to turn it on and nothing, not a click, nothing. Battery is charged, all connections look good. (2) The transmission will not deliver power to both wheels simultaniously. And if you're on a hill going sideways along the hill, it will send power to the wheel on the high side, the wheel that the weight is not on. Does it on both sides and I never get 2 wheel drive. Any advice would be appreciated. Thanks, Rob
I had the a similar problem with my 48 inch 22HP Husky. After much trying I finally determined it was grass and dirt stopping the "brake on" start interlock lock from working. I looked under the mower as well as I could and spotted the interlock. I removed grass and dirt with my hand and the mower immediately started and continues to start. I spent a lot of time on "other" things before I did this...but a little cleaning of the area where the brake on start interlock is fixed it.......this is easy to check once you locate the interlock under the mower........the mover doing "nothing" is a good sign one of the start interlocks is not working......
Bent push rod due to rodent nest is very common on these..head over heats, valve guide comes out so valve (s) can't open,,botta bing,,one or more bent push rods..and mice love these engines..obviously somebody quit while almost finished on this one because the valve guides were back in place..very weird..maybe somebody just couldn't find push rods even tho they are $10 on ebay....:???
Talented and knowledgeable mechanic!! Extremely immoral person if you sell that mower to an unsuspecting customer with an 8" piece of metal floating around in the crankcase.
I think you did alot of unnecessary electrical issues hunting which isn't the problem. You suppose to set on the seat when you engage the pto if the seat switch isn't closed it kills the magnetic clutch.
I am disabled and I can't push mow now I got me a Husqvarna and it won't move forward or backward belt good I think it might be the transaxle need help

Great deal. Very clean and rust free. Was surprised when it just started. Good detective work finding the valve issue.
Thanks 👍
No
What an awesome find. I wish I could get lucky like that just once..
Nice job on the troubleshooting Bob, hate it for the guys misfortune but glad you have another sound mower to sell. 👍🏼🙂
WHAT!!!
Nice piece of detective work DW6, always learn something from your vids, thanks! 👍👍
My pleasure

Wondered the same thing
Had a Briggs v-twin do the same thing found the exhaust push rod wrapped around the camshaft.
Yo yo brother.. another great job.. a little fault finding and it's up and running.. good for you .. hope all the family are doing ok..
Don’t you have to sit on the seat when you engage the pto? Seat switch
2 mins into this video and I knew what it was. This guys some mechanic
Great find and repair and the engine has one extra push rod. Thanks for the videos.
Stopped video at 12:05.

Good find. Guy prob started hiring yard done. So parked tractor that was good got sat on curb. Enjoyed

Manual PTO over electronic all day long
Nice find, but as far as I am concerned, it aint fixed until that push rod is out !!
Need to sit seat for mower to start.
One of my favorite tractors good repair ✔️💪🏽

That was a great find that Husqvarna tractor unfortunately it had issues especially with the pushrods .
Bob you have to be sitting on the machine mate for it to start.

Mate?? Have you gone English? HaHa:) Sounds like Mick is wearing off on you. Take care, buddy.
That would make sense.

Nice curb find Bob. It should be worth good money now. Were you able to fish the other push rod out with a magnet? 👍🇺🇸
Not yet
That's what I had to get my steel rod out. Used a telescoping magnet when I couldn't see the rod.
Had a Briggs v-twin do the same thing found the exhaust push rod wrapped around the camshaft.
me too. looked like a pretzel.
What about the rod that’s loose in the bottom of the engine😳?
you need to remove the metal push rod, it will move from the bottom of the pan and do some serious damage your repair is not over
Good mower for sale. It comes with the three push rod engine.
Nice find Bob .And a neat fix .
Seems to be a good running mower. Great score for you. Did you ever look for the missing push rod?
you have to be on the seat for the pto switch
You are very fortunate there was sufficient oil in this engine.
With 55-60 PSI that would be about right because of compression release. But that went straight to 60 PSI which is odd. Since the valves weren't working, it would indicate a problem.
A good fix. I just wonder if the push rod is in the oil pan, it could create a problem. Maybe.

Lights shorted out the fuse?? Find the fuse and check it. Good Luck
I have the 2654 Husqvarna mower. There is two long on the air filter trying to find out where they tie into. Can you help me with that?
Not sitting on seat , obviously pto will then kill motor
surprised he didn't realize that unless he had put a weight on the seat?
lol I thought you had to sit on seat to keep PTO to keep engine running? Soon as my (#(# comes off the seat while running it dies!
That my friend was either a sad repair or a sad video because you didn't show checking or looking for the other push rod.
Mine doesn't crank at all, it's not that old. It's a 2019 Yth24v54. I've replaced the key switch, seat switch and nothing. Battery is good. One day I tried cranking it and it started, two days later it didn't start again. Makes me think a wire is not making contact somewhere.
This was hard to watch, 1st thing on these single & 2 cyl engines is pull valve covers.

Nice Score
Good video, great score!
Where's the push rod?
It’s nice when it’s easy and nothing is wrong.
I think you did alot of unnecessary electrical issues hunting which isn't the problem. You suppose to set on the seat when you engage the pto if the seat switch isn't closed it kills the magnetic clutch.
Yes couldn’t agree more
agood ONE!!!!!!!!!!!!!!!
How can you say that those engines are notorious for having valve problems. How many have you had with valve problems?
any engine that gets its cooling blocked will have valve problem.
Nice satire 👍 convincing
Some people have more money than brains
What a deal...
Head gasket, big problem with this engine
What a pain in the ass,, I'm buying a new one..
Maybe you should take it to a professional.
I am disabled and I can't push mow now I got me a Husqvarna and it won't move forward or backward belt good I think it might be the transaxle need help
