Yamaha Warrior 350 engine and transmission overhaul (rebuild part 3)

[@FlawleZ31]

Really good breakdown of your process. Not sure why you have some negative comments. I just upgraded my piston to a 10.25:1 in my '98 Big Bear 350 which is very similar to the warrior.

[@everythingmechanical_yt]

Thank you! Yeah they use the same top end and everything I bieleve

[@RichardBowers-g5j]

just found this video,you are defiantly not a mechanic,but what you are is methodical, and intelligent,this is a very good overview of necessary steps required for this overhaul,well done.50 year 2 ticket mechanic, and still learning

[@DaytonTrailRiders]

Will do. Gonna be a pretty penny. Did you see the last video?

[@DaytonTrailRiders]

It was lack of oil flow from the filter and she got hot and ruined the rod bearing and crank bearings and crank is junk too.

[@everythingmechanical_yt]

@@DaytonTrailRiders I will check it out now! Yeah my neghbor had that issue because he stripped out all the oil filter bolts and never changed it haha. I welded some nuts on the end in order to get the cover off and man that thing was so filthy with clutch dust. It's no wonder he didn't get any oil up to the top end!

[@DaytonTrailRiders]

Mine was from black rtv in the oil filter housing and clogging up the oil jacket from whoever worked on it before me.

Watching this now but hope I dont need it lol

[@eddiesheeran5791]

Have you ever broken a cam chain on one of these warrior engines? There's a local warrior on FB listed for $1000 that snapped a cam chain and I'm tempted to pick it up. He said a mechanic checked it out and nothing else was damaged, but that's pretty unlikely in my experience. What do you think, send it or pass?

[@everythingmechanical_yt]

Make sure you know the prices in your area. I would only buy it if it's a really really good deal. Usually on these engines the timing chain will stretch and cause a "knock" as it slaps against the bore. If it actually snapped, it must have been doing this for awhile. It's possible that nothing else is damaged, but it's likely that the engine has a lot of hours and wear on it, it takes a lot to snap one of those

[@eddiesheeran5791]

@@everythingmechanical_yt Thanks for your feedback man I really appreciate it. KBB says it's worth 2k in good condition, but I'm not sure if people even care about KBB or not. I'm new to the market, I'll have to watch it for awhile. Cam chains are cheap and I'll be doing the work, but if the whole engine needs to be overhauled, I'd pass.

[@everythingmechanical_yt]

@@eddiesheeran5791 yeah the problem is it won't run when you get there. If I were you I would see if I could talk him down a bit. $1000 isn't bad in my area but it differs. Based on what you said I'd say it probably has a good amount of wear on it

[@eddiesheeran5791]

@@kalieking5561 I bought it anyway. The kid + father were both lying POS, it didn't need a cam chain. There was piston skirt in the crankcase, and the motor was locked up. They had drained the oil beforehand "to do me a favor" - what they actually did was hide the evidence of the engine grenading. I haven't torn it down any further yet. Trusting people is a REALLY BAD idea. If you're meeting with a random seller, assume everything they say is a LIE unless you can verify the claims yourself. I bought it anyway because I knew it needed an engine and I wanted to build one myself.

So, what if it doesn’t shift through the gears?

[@everythingmechanical_yt]

That means you did it wrong

[@skeletonweevil8511]

@@everythingmechanical_yt I have a question. I fixed the shifting issue. But my question is that when I put it in neutral the sprocket still spins. Is that normal?

[@everythingmechanical_yt]

@@skeletonweevil8511 when you put the transmission in neutral, you should be able to spin the input shaft, but the output shaft should not spin. It may be possible that it spins a little bit but should stop if you hold it with your hand (it's been awhile since I did this so I don't completely remember). If it seems to still spin while you spin the input shaft it must still be in gear and something isn't right

[@skeletonweevil8511]

@@everythingmechanical_yt hmmm, okay. Thanks a lot for responding and trying to help. Really appreciate it. I noticed that if I remove the top gear that connects to the top gear of the output shaft then it stops. Idk I’m just confused at this point. Trying to fix it because I hired someone to rebuild it and they built it wrong. Think I’m getting closer though

[@everythingmechanical_yt]

@@skeletonweevil8511 no problem. Watch the video and see what gear you removed. It's possible it was just stuck in thag specific gear and just spins as if you lost that gear. Also make sure you have it in neutral, not first or second. The roller should be sitting in the small half moon looking notch on the shift star and the deeper grooves are individual gears

Could anyone help me it goes in reverse(warrior 350 2001) but when in 1st gear it just idles no budge no cutting off no nothing just idle i did rebuild the engine from Top the bottom any help would be nice there’s nothing about this around the internet

[@deedadon7142]

So I rebuilt warrior 350. Put a new piston from amazon in it because it had a 5 star rating. Crankshaft spins fine, new timing chain and valve clearance is set properly. Once I install cam the motor only turn half way and stop forward or backwards. No spark plug is in it so it should spin freely but it’s not. I took the cam back out and noticed a deep scratch inside head like cam is too big to spin but it’s the original cam and was spinning fine before the rebuild. TDC is perfect so idk what else it could be to cause the original cam to not turn. Can someone give me suggestions please?

[@05hutst]

Did you time it up properly?

[@luly8083]

My 95 warrior 350 will blow some blue smoke after on for a while. Is this what I need done? Thanks

[@everythingmechanical_yt]

It could need new piston rings or valve guide seals. If your quad burns oil (blows blue smoke) after it's warmed up, you likely need new piston rings. If it's only when it starts up and goes away once the engine warms up, it may just need new valve guide seals. I demonstrate how to do these in the video, however both piston rings and valve guide seals can be done without removing the engine from the quad. I have a video doing piston rings on a Yamaha Wolverine 350 that you can follow since it uses the same top end. Let me know if this helps!

[@luly8083]

@@everythingmechanical_yt Really appreciate your prompt response. When it warms up and I accelerate a get some blue smoke mainly from the header because the screw came undone.

[@staceyclass7416]

Why you didn’t show how you put the rings on the piston and when you did the valves you didn’t show nothing this whut we want to see

[@partytime11]

After finding this video I want to put this comment to see if anyone would know possibly what’s wrong with my quad. I got a 2007 Yamaha raptor 350 I’m in the middle of doing the timing chain and when I drained the oil I had some metal in it but not a lot then I took the oil filter off and had a bunch of metal shavings on the filter and in the oil filter housing. When my quad is hot it doesn’t like it shift into neutral does anything think that the neutral gearing in the engine is bad or could it be something else causing my issue?

[@everythingmechanical_yt]

A lot of people think they have metal in their oil filter when it’s really just clutch dust from normal wear. Unless you have chunks of metal in the filter or more likely the screen, you’re probably okay. Check to see if the particles are magnetic first. As far as neutral being hard to find, your shift star or spring could in theory be worn out but I’d say it’s unlikely. If your bike has an aftermarket direct mount shifter that can make it harder to find too.

[@partytime11]

@@everythingmechanical_yt I had some pretty small metal chunks in the oil it’s self but nothing huge. I didn’t know if the shift cam assembly would cause something like that or possibly the neutral gear itself is going in wheeler. I just don’t want to run it and have something in the gearing blow or something if it’s potentially only the shift assembly

[@everythingmechanical_yt]

@@partytime11 I doubt you will, honestly these engines are really tough and the oil pumps are really strong, I’ve seen some pretty big chunks of metal in the bottom of these engines even a tooth off 4th gear and we didn’t know until I tore it apart for a rod knock. I’d check if the chunks are magnetic but again if it looks like a little bit of glitter in the oil filter it’s probably just clutch dust

Yes. Obviously you would need a new connecting rod. Since these can't be removed from the crankshaft on warriors without major equipment, you will most likely need to replace the entire crankshaft as well. Then repair or replace anything else that got damaged when the rod broke.
