95 bayou 300 2wheel. This is my first four wheeler. The guy I bought it from showed me slight drip on his floor from a drain plug he recently retapped. I figured I could handle a small leak from a second hand machine. Well after a few times of riding it the bayou seems to be running low on oil. Now maybe this is normal operations as well so I refilled the oil. But the next day I notice my drip on the floor was slightly larger. I wanted to see this drain plug for myself so I took off the skid plate and found a pretty rough looking installed drain plug. It does have a small drop but also seemed to have an excessive gasket and maybe some grey looking “jb-weld” ish material around it. So that’s scary but I figure surely that’s not the only source since my floor spot Grew a bit. I went on to find recent moist around the head gasket for the top end. I’ve never seen it drip but it drips on the new starter the guy installed so it seems the head gasket leaks too. He did say he replaced that gasket when I inquired about the darken stains around that area of the motor. He said he replaced that gasket during. Ring replacement when the bayou was smoking. It no longer smokes by the way. So I continue on thinking well maybe I can do another top end gasket myself some day but still the oil on the floor suggests a more visible leak. I mean it’s not a lot but it grew as I mentioned. Then I find my what seems to be an awful thing. The pull cord and starter was replaced by the preavious owner and it appears there’s a busted area on the crankcase where the left side cover mounts to the L-case.I have not seen oil from there but that looks scary to me. Does this area hold oil? I wondered if it doenst maybe I’ll leave it be but if it does it’s probably the reason I lost some oil. I also found tonight oil on the rubber boot cover I think is for the drive shaft or something. Idk my first ride so I’m unsure of how to proceed. Especially with the case cracked like that. I don’t know how the engine works but if there is indeed oil there in the operation of things it seems like I must do a major engine over haul….. any insight would be so very helpful. I bought this for my daughter but I may have been bitten by going with such An older model.
I have a 2015 sportsman 570 in the shop currently with a cracked oil pan. It is a rental unit, (not my own rental company but a customer's) and the renter that was riding it apparently hit a large rock and dented the bottom of the skid plate into the oil pan and has cracked it where the drain bolt is. (And before any-one tells me to just JB weld it, I am not going to do that for obvious reasons relating to it failing down the trail. ) It is a quite large chunk that is broken and oil drains out about as fast as you can pour it in. I currently have the customer quoted for removing the engine and replacing the oil pan. Is this the best option? Or should I be looking into cutting the skid plate out, replacing the oil pan, and welding the skid plate back into place? Has anyone done that before?
Thanks!
A friend has a 07 trx 400ex..the engine drain bolt housing has a couple of cracks where the drain bolt threads in and is leaking oil...a one had any luck sealing this area with JB weld or something similar ?
I have a 2001 Honda Recon TRX250 which I am basically rebuilding the entire machine with new parts (a project bike). The two head bolts broke off flush with the engine block so I carried it to a machine shop. The guy calls and says everything went good but the engine cracked out and around one of the bolt holes and he said that he could “doctor” it up. I’m a small engine mechanic by trade and have never came across this type of predicament because the head as we all know has to sit perfectly flush on top of the engine block. My question here to anyone in the know would be... Is it possible to “safely” doctor up such a delicate place on the block or case should i say and without fear of having issues with blown gaskets and/or any sort of problem at the site which would require a new case. I realize they are in two pieces and i could get away with buying one side, but I’m trying as most folks do to get away with spending less. Any feedback would be much appreciated.
I have an 03 ltz 400 that has a crack in the left engine case right by the shifter. Wanting to know if that is a common problem with the motor? Thanks!
