Tack ska du ha!

[@willybaldsirhenry]

Wow many thanks for this video. I always wondered what the K46 looks inside. Incredible level of information.

[@berg310tor-arnejonasson8]

Thanks a lot

Hi, my stiga park comfort doesn't move well when cold. Is it cos of old transmission oil? And where's the draining hole for that? Thanks.

[@berg310tor-arnejonasson8]

I would start with changing oil and oil filter. The drain plug is in the center of the gearbox, you can see it in the video

[@aksuli1]

@@berg310tor-arnejonasson8 You mean motor oil? My model is 2006 and bought it as used past summer. Haven't changed any oils yet but air filter. It doesn't have oil filter.

[@berg310tor-arnejonasson8]

@@aksuli1 No I mean gearbox oil, there is a filter inside the the gearbox (Tuff torq K46) but you have to disassemble the Tuff torq K46 to get to it, like in the video…

[@aksuli1]

​​@@berg310tor-arnejonasson8 Ok thanks 👍. But you don't have to dismantle all the parts just to replace the filter, only the cover?

thank you , it help me alot to fix my transmission

[@berg310tor-arnejonasson8]

Thanks! Nice that it helped a little

[@igormoeller]

Very nice teardown..and good info..my k46 suffers simmiliar (loosing some power when really hot). I wondered if pumps could get machined to remove marks..and you answered that question (i would hate to buy rebuild kit - costs a fortune ).

[@berg310tor-arnejonasson8]

Thanks and good luck!!

[@vanover69]

Great video. I have a question you might be able to help with. I have a 1990 Ariens tractor that is have a issue. The mower wont move forward and make a whining sound...it move backward strong and fast...just not forward. The belts seem to be tight, the fluid seem to be full, the linkage seems to be moving. The mower is in super good condition and hope to save it. Any help would be great...Thanks

[@Tinyhomefixers]

Min kasse har ingen drivning längre. Saknade inte olja. Filtret såg illa ut. Kan det göra så att man tappar drivningen? Undrar oxå på om drivningen kan justeras med den bulten som har fyrkantig bult huvud med en låsmutter på? Tacksam för svar

[@charliekyriacou6215]

Great video! one question: What did you use to polish there center base plates?

[@berg310tor-arnejonasson8]

I have a lapping machine at work, manual but high precision

[@blainemcmillan6228]

My mower loses power when hot to wear it will barely even drive I'm at the point where I need to tear down this transmission I'm not sure if it could just be a clogged filter or if maybe there's a problem with the axle seals. When I change the oil in it it was very very hard to fill up the transmission again because it didn't want to take any oil I had added a little bit at a time and it took me a whole day to get a level back in it I'm not sure why that was. Do you have any answers or advice

[@berg310tor-arnejonasson8]

Hi! To fill the oil faster you kan remove the plastic plug as shown in the video, this vill make it in a few minutes. About the drive it sounds like the there are some scratches on the hydraulic pump or motor. Then it needs to be reworked. Best regards Tor

[@sshvulnerability]

Can you show the process for polishing the pump?

[@Tinyhomefixers]

Jag vill gärna också se det🙏🙏

[@berg310tor-arnejonasson8]

Sorry, I don’t have any video of that, but I am using a face polishing machine at work

[@danielnorinjanson5647]

This really helped me a lot! Thank you so much dear Sir!

[@berg310tor-arnejonasson8]

I am so delighted to be able to help!

[@csanivehrer4777]

Hi! I made the rebuild but when i use the mower the forward end the backward exchanged?! What can be the problem?

[@berg310tor-arnejonasson8]

I mention that problem in the video, it is the wedged plate that is mounted upside down

[@almantas199207]

If my lawn mover after moving up all to one side iand after putting back to driving position is starting to drive heavy and i heard the sound so it means that oil is missing or there is more trouble ?

[@berg310tor-arnejonasson8]

It’s very difficult to say with out knowing what kind of gearbox and drive it is

[@KaiserBlade]

I wonder which bolts were to drain the oil?

[@Ekmanjohnny]

Jag har en stiga tornado 2098 från 2014 och har märkt att den är väldigt trögväxlad. Det är ju ingen hydrostat på den men finns det olja eller fett i den transmissionen?

[@berg310tor-arnejonasson8]

Hej! Ledsen men jag har ingen aning, har aldrig tittat på en sådan. Mvh Tor-Arne

[@travisbacon5527]

Would have like to see how you polished the pump. That's like the main issue.

[@berg310tor-arnejonasson8]

Well, I agree that it would have been nice to see but it’s quite simple. It’s just a face honing machine with a manual pice holder. But I did it in the factory wher I work and ther is no photo or filming allowed So sorry about that!

[@keithmeyers3718]

Is any way to polish the surfaces by hand?

[@berg310tor-arnejonasson8]

It depends on the damage, if it only scratches it can be polished by hand. In other cases you need a good lapping machine

[@Knolle18]

Thanks for your documentation about disassembling the transmission! Am i right, that you filled it up to the top With oil? I Saw some other Videos about changing fluid and they used about 2 Quarts (2 litre). Thanks for your work and keep up the work and swedish talking in the background. Always nice to have friends around while working on engines and other things

[@berg310tor-arnejonasson8]

Hi! And thanks for your comment. In this drive it should be filled with oil and then on the lawnmower there is a small container that shall be filled. Unfortunately I don’t know how much oil I filled because I used a pump. But any way this one should be absolutely full Thanks and have a nice day!

[@mikaelkarlsson3212]

Vad var det du gjorde med pumpmotorn mer exakt? Mvh

[@niklavsciss8256]

Hello, what oil you used?

[@berg310tor-arnejonasson8]

Hi, I used Standard 10W30 oil. And have done so for many years

[@dannyboy5300]

Hur mycket olja går det i ungefär ?

[@PeterSiekiera]

Great video

[@berg310tor-arnejonasson8]
