Bonneville America Forums Forums Technical Forums General Tech Torque Specs on Sprocket Cover Bolts

Hey folks,

I just learned the hard way that I apparently overtightened one of the sprocket cover bolts the last time. Hopefully Triumph keeps these in stock. I need one bolt so eloquently described by Triumph as "BOLT,RHHF,DOMED S/LESS M6X50 "RHHF, M6 X 50, S/LESS". Anyway, does anyone know the correct torque these should be on with? I figured it was only a cover and went via feel. Bad mistake. Apparently I ate my Wheaties that morning...

Thanks in advance,

Steve B.

9nm according to the manual

Roadworthy,

Thanks! If you don't mind me asking, did you find this in the service manual or the operator's manual? I am just starting to work on my bike and didn't see it in the operator's manual. What began this was I think I'm leaking a little oil. Yesterday, I went for a 130 mile ride and when I returned I noticed two wet drips under the bike. Upon inspection, I had a coat of oil all over the bottom of the engine. This happened when the bike (05 America) was new (it now has 19,000 miles on it). It was determined that a few of the bolts on the bottom of the engine weren't torqued down correctly and loosened up. Once tightened by the dealer, all was well. Anyhow, I figured I also just oiled the chain, that may have been the issue also. So I started to clean up the bottom side of the motor and in doing so, snapped a sprocket cover bolt.

I guess it is time to order the service manual. In the meantime, can I trouble you for one more? What torque should the bolts at the bottom of the engine be? Trying to ease my mind and still get a few miles in today. I figure the sprocket cover should be fine with 4 out of the 5 bolts holding it.

Thanks,

Steve B.

I got it from the service manual. What bolts at the bottom of the engine are you talking about?

Roadworthy,

Thanks! I was talking about the eleven bolts that hold on the oil pan.

I Ordered the factory service manual .. ring binder... when i got my bike .. used .. a year ago .. wonderfull thing to have .. takes awhile .. triumph had to have it printed.
lol guess they dont get alot of requests .. worth the hundred bucks .. all day long !!

Well, I think I may have a legit oil leak, although a minor one. Just got back in from a short 30 mile ride. Noticed oil on the bottom of the engine right under the sprocket cover. Started thinking that the leak may be just oil from the chain, however, I noticed it is golden brown and not clear with some dirt in it. The golden brown color looks exactly like the Mobil 1 4T oil that I put in the bike. Once the engine cools (I learned my lesson already), I'm going to take a look at the sprocket. Gut instinct tells me the seal in there is going to be the culprit. Anyone have any experience with these? I'm thinking I may be taking her in a month early for inspection this year...
