This TC85 needs a new crank. Come along as I rebuild her and get it back up and running again!

Thanks for using the word thread-locker instead of the brand name of a company that hates dirt bikes and all people that ride vehicles off road. Another great video with lots of very useful information!!!

[@UpAllNight91]

Right on! Thanks!👍

Thank you for this good video! My sons 2022 KTM SX 85 had just a rod bearing failure. It worked ok without any noise and suddenly it just cut off and the lower rod bearing got very loose and has a lot of vertical play. I’m glad this failure didn’t destroy the whole motor completely. Cylinder, piston, cylinder head etc. all in great condition. We had a good luck after all...
We just ordered a new crankshaft, crank main bearings and Wössner piston + all the gaskets and seals. This video has great info how to do this.

[@UpAllNight91]

Your welcome! Yeah thats always good when its caught before it does any further damage. Surely saves a lot of money! If you run into any questions let me know.

[@jcody_parker]

Great video, super in detail with good info. Most of the other videos don't talk or explain much at all

[@UpAllNight91]

Thanks! 👍

Good🎉

Thanks!

Great work! I learned alot from watching this. Question: how did the owner know it was time to have the engine gone through and rebuilt? Did he just go by an hour meter, or did power fall off, letting him know? thanks again!

[@UpAllNight91]

Thanks! The motor started to sound like the piston was worn out and slapping around. When he brought it to me we both thought it was just a worn piston and or cylinder. Didnt expect to find the cranks lower rod bearing was becoming sloppy and loose too.

[@joelatkinson2080]

I've heard really good things about Wossner forged pistons. I'd really like to hear your opinion on Wossner vs Wiseco pistons.

[@UpAllNight91]

Hello. Wossners are good forged pistons. I cant say how they compare to wiseco but they seem very similar for the most part. I dont have a lot of experience with wossners and never used one myself but I have installed them in bikes for people. They are surely a pretty piston.

What camera do you use?

[@UpAllNight91]

A samsung S7 phone on a tripod. Its good for close ups but not good at distance.

How often would you be rebuilding a 2023 kx450 ridden at AA level? Just curious. Bike seems to be low on power currently, especially bottom to mid.

[@UpAllNight91]

Hello. If they are hard on the motor I would probably suggest a top end every 50 hours. I have found when the timing chain ages it retards the cam timing some. This can rob some bottom end power. A new timing chain along with a fresh top end should bring to how she once was.

[@donbridgewater2988]

Why did you replace he whole crank instead of just doing the rod bearings?

[@UpAllNight91]

I save rebuilding cranks for when new cranks are no longer available for that make and model. I have a few reasons why I choose to use new cranks. A new crank will hold true better than a crank that's been rebuilt. New rod bearing, and labor to have a shop rebuild the crank can often come up only about 100 bucks cheaper than a new crank all together. Today I know how to check a cranks true and true in a crank if needed but years ago before I knew how I had a crank rebuilt and the shop did not true it in good. That crank only lasted a few hours and it ate the crank bearings up and wore into the cranks journals. Maybe one day I will take the time to try to rebuild a crank myself but even then a new crank will still be the first choice because every time the crank is pressed apart and pressed back together it becomes a little weaker at holding true.

[@joelatkinson2080]

@@UpAllNight91 I think you doing videos about start to finish crank rebuilding would be awesome content.

[@UpAllNight91]

@@joelatkinson2080 Right! I been meaning to test out and see if my 20 ton press is even enough to push a crank pin. Hmm

[@bradley7723]

Another great video. First time I've seen a husky apart. Thanks for taking us on the rebuild adventure.
P.S if the only thing you forgot was a case gasket for totally the obvious reason, you are a winner in my book . 🏜👍

[@UpAllNight91]

Thanks Bradley! You know how it is, your on a roll and then you have to stop the job to order something else and wait lol. Alls well that ends well though lol.
