Crank Case Cracked!!

So I obviously missed it last year & thought my clutch cover was leaking above the kick start. Turns out there is a hairline crack in back of where the mount is!! Unreal. Camping/quadding season just kicked off for me. Iíll have NO time to fix it properly before winter as itís in full swing here. Iím going to degrease, sand it & either JB Weld or black oil resistant silicone/gasket maker. Just need to buy time!! Iíll post up pics when I get better cell service.

Some more info on the stuff , I seen it go locally for any wheres from $16-19.99 ---I have used it about 4 times now , the most extreme and why I bought it was I had a lug that spun in a drum from the nulling stripping on the lug , I applied the stuff waited 10 minutes an hit it with a 1/2 air impack and it held ---- I used it yesterday and stuck a stainless eyelet in the end of a handle for my bell on the porch

and would all that add-on crap you did to it cause this crack ?. I dont know ?, just asking :-). I have never seen them crack at that spot, most oil leaks i've seen are from a stripped oil drain plug ?, or a bad gasket matting surface ?.

I've never seen one crack there either. It is possible because of the extra power it caused the crack, but I will never know for sure. When I split the case & put a new one on, if it cracks there as again, then I guess we will know the answer....


Add on crap lol? You mean a bbk to make more power? lol.. You're funny shade!

not the top end crap, the clutch kit stuff, surely this would cause extra stress on the engine cases, and tranny.

No BIGGY with a cracked case ------- I had two different 300 cases with cracks in them this year , first one no doubt was the PO beating the side cover at the bearing holder and cracked the side cover , I could have fixed that crack , just threw another cover on it --------- then I found a chunk of case that was right on the threaded bolt hole , I was able to fix that one by making it into a stud instead of thread bolt hole , used JBWeld on that one ---I am liking that CRC Minute Mend better and JB Weld , it can be shaped smooth during application before quick curing , in other words , it stays where you put it
