i have a question i was hoping someone can help me with. When i was changing the oil on my tw, i snapped the head off of the oil check screw in the cylinder head (the screw in the last pick of this how-to: http://tw200forum.com/forums/43754/ShowPost.aspx. When i ordered the replacement, i noticed the product number had changed to the following, 90153-06029-00 SCREW, HEXAGON; however, when i received the screw, it is double the size of the old screw. i started screwing it into the hole, but it started to give me some resistance about half-way to being in. I decided not to force it and did not use it.



Has anyone else had to replace this screw? if so, should i just go with what Yamaha is telling me and use this new screw that is double the size? this is possibly a stupid question with "yes!" being the obvious answer, but i just thought it was odd to see such a difference in the new part compared to the old one.



the part i ordered was tag 3 in the link below.

EDIT: im not sure why the link to the how-to is not working, but it is the oil change how-to pinned in this section

Hi Tom,



When you say "double the size" are you talking about the diameter or the length?

thank you for embedding the picture.



yes. by the grace of god, i was able to get the broken piece out.




You're very welcome. I'm happy that you got the old screw out as others haven't been so lucky. I have no clue as to why the new screw would be longer. Hopefully someone that has been in your shoes will chime in.

I just went out and took my bolt out and measured it - the threaded portion is 10mm in length.


I get the same measurement on the original one too. I'm not sure how long the replacement was because i cut it down to the size of the old bolt. My concern now is it looks like there is a little oil leaking from the screw hole, so i think my solution did not work.

I am too. I didn't think i would be able to get it out, but persistence paid off. There was oil on the threads so i was able to unscrew it little by little using the tip of a tiny screwdriver. I don't know either. I'm going to reorder the part from Stadium and see if I just got the wrong part last time.



EDIT: Well scratch that. It's $15 to ship the screw and washer. I'll just go to the Yamaha dealer and order it.

I had the exact same experience you did the first time I changed my oil, head snapped right off and I was fortunate enough to be able to back out what was left of the bolt with an eyeglass screwdriver.



I wouldn't waste your time or money ordering a machine screw from Yamaha. I bought a pack of Dorman Brand Class 10.9 Hex Flanged Cap Screws in size M6-1.0 x 10mm from my local Autozone and used one of them. I think the 4 pack was about $2.50.



The replacement works perfectly, and I make sure to only loosen or tighten this bolt with a bolt driver so I don't damage the threads with this much stronger fastener.



I couldn't find a perfect match even at Ace hardware, but the auto parts store had scads of em.

HA HA HA HA HA!



After pulling my bolt out and measuring it an hour ago, when I went to put it back in, it broke off! - Holy cow poop!




Anyway, after 30 minutes of fiddling around I was able to get the broken piece out. (I used a center punch and a small screwdriver, but I ultimately had the best luck by taking the copper washer off the (broken) head and putting the head (that had 2 threads on it) back in there. The bolt had a bit of a spiral fracture and the when the head and the broken piece connected up in their original orientation they locked together enough so that I could get the broken piece to unscrew.)





DonBenito - thanks for the timely info. I was going to head to Ace Hardware, but after your message I will be making a trip to AutoZone and use one of those bolts until my next RockyMountainATV order.

Thanks for the tip DB. I will stop by autozone and pick up what you recommend. I went to home depot and Loews looking for a replacement when it happened and neither had what I was looking for. I didn't think to try autozone.

Aw man that sucks. No good deed goes unpunished.
I'm glad you were able to get the remaining piece out. I guess this happens more often then I thought. I can't believe how easy it was to snap the head off of that screw.

Man I love this forum... Glad to hear I am not the only one that had this happen. Just finished my first oil change on my new 2012 at 120km. Went pretty well thanks to the instructions on the forum, until I loosen the oil check screw. Thankfully oil came out of the hole, but went to put it back in and apparently torqued to hard and 'ALMOST' twisted off the head.. thankfully I stopped before it snapped. Will be using the info here to go buy a new bolt..



One other thing happened that I hope is not too big of a deal, when I was taking out the filter to clean the filter was stuck to the cover, and the rubber gasket from the filter stayed in the engine.. I as able to pull it out of the oil filter opening and put it back on the filter and am hoping that is ok.

Should I go and buy a new filter just to be safe???



Thanks,



Margo

I wouldn't worry about it. The force of the cover should keep it from moving around. If it were me, I'd use it and when i was near the dealer I'd buy another filter to replace the ruined (not really ruined, but you get my drift) one next time I did an oil change. I always like to have an extra filter in my toolbox just in case. Make sure to put a little motor oil on that rubber seal before putting it back in the motor so next time it'll come out with the filter.
