    1986 250ES Big Red Clunks When Shutting Down

    Hello all,
    Long time troller, first time poster. I have a question regarding the clunk that I am hearing when I shut down my Big Red. It's definitely coming from the L/H side of the engine. I have already replaced the one-way clutch on the right side which took care of the kick start issue & I inspected the left side one-way clutch while I had it opened up. The one-way clutch worked fine by hand and there was no noticeable wear on the starter gear. While I was in there I replaced the needle bearing that goes between the crank & the starter gear (L/H side). Once I got it all back together, I still get a clunk to varying degrees when it is shut off. I am worried that this will damage the starter reduction gears if I use it. I found a NOS one-way clutch for the L/H side & once it arrives I will install it to see if it will eliminate the issue. My question is there anything else that I may be missing to cause this issue? It's been so long since I've heard one that I knew was correct, that I can't remember what sound it should be making or not. I know the clunk & spinning sound is bad (fixed), but is a slight clunk normal? I've only started it about 4-5 times since I've put it back together. It seems to vary but at it's worse, it sounds rough to me. Any help, is greatly appreciated.

    Yes replace the starter one way bearing and it will help , but they all make that noise to some extent even when it's all working properly .

    Ok, it seemed to me that they do, but I couldn't remember. I just don't think it should be this bad. Thanks for the reply.

    Clutch was delivered today, just got it put in and that fixed it. Sounds so much better. When I heard it, it was like, "Oh yeah, that is what it should sound like". Funny how you forget.

    Awesome ! At least you got it repaired before it tore up the starter gears
