dann2707 Posted October 10, 2012 Report Share Posted October 10, 2012 My snail cam bolt hole on ones side of my Rockman Manus was fungled up before I bought it. What size is the bolt? Is it the same size as a maggy bolt? So does that mean I need an m5 helicoil kit? Completely new to this so sorry if it's a newbie question haha. Cheers!

Martin Reynolds Posted October 10, 2012 Report Share Posted October 10, 2012 You could always get it tapped and use a m6 bolt? Quote Link to comment Share on other sites More sharing options...
N.Wood Posted October 10, 2012 Report Share Posted October 10, 2012 Could you not just run a nut and bolt? Quote Link to comment Share on other sites More sharing options...
dann2707 Posted October 10, 2012 Author Report Share Posted October 10, 2012 What would an m6 benefit over a helicoiled m5 thread? (not arguing, just curious) And nut and bolt is a no go as it doesn't go all the way through the frame. Weld is right on the other side of the hole.

Martin Reynolds Posted October 10, 2012 Report Share Posted October 10, 2012 Either would be strong enough. You're pretty special to thread a snail cam bolt, all you need to do is 'nip' them up so they don't come loose. Quote Link to comment Share on other sites More sharing options...

I didnt mean 'you' as in you dan, i meant as in people in general Oh right I see haha, Sorry you could drill through the weld surely? I could, but it's not exactly ideal and i'd have a gash looking bolt sticking out of an otherwise sexy looking frame Quote Link to comment Share on other sites More sharing options...

dann2707 Posted October 10, 2012 Author Report Share Posted October 10, 2012 I'm just going to helicoil it. Easy enough just wanted confirmation on what size but i've found it out now. M5 x 0.8 helicoil x 1 Dneeded. Interesting to know that you can specify how big the helicoil thread will end up determined by the x 1d at the end, 1 D is x 0.8 so it will end up at 0.8mm long thread. If you were to choose M5 x 0.8 x 2D the thread will be 0.8 x 2 so the threaded insert will be 16mm long. Useful information incase anyone reads this in the future like. As the snail cam hole depth is tiny as cheesecake I need the smallest insert size ( x 1D) Quote Link to comment Share on other sites More sharing options...
isitafox Posted October 10, 2012 Report Share Posted October 10, 2012 I knew that'd get mis-interpted. I didnt mean 'you' as in you dan, i meant as in people in general It happened in Leeds one day, cause there's no thickness to the frame where it screws in it just got torn out by the wheel. When you sort it, can I have my washer back in exchange for the original echo washer!! Lol Quote Link to comment Share on other sites More sharing options...
dann2707 Posted October 10, 2012 Author Report Share Posted October 10, 2012 Eeeeek don't say that. Washer for what?This is why I f**king love onza and echos chain tensioning system. It's flawless and as accurate as you like. 1 Quote Link to comment Share on other sites More sharing options...

When you sort it, can I have my washer back in exchange for the original echo washer!! Lol in that case, id be tempted to drill and tap it completely through. i run an stock x-ray where the snail cam bolt hole goes completely through the frame, and its been fine for the last year, and i run some pretty high chain tension!

isitafox Posted October 10, 2012 Report Share Posted October 10, 2012 I gave him one of my toothed washers that goes on the wheel bolt to hold the wheel as the echo ones are smooth. Then 5 mins later he fell off that wall near the gallery(?) Quote Link to comment Share on other sites More sharing options...
dann2707 Posted October 10, 2012 Author Report Share Posted October 10, 2012 Ohhhhh I'm with you. It's got matching black ones now, think they are from Neils bike as they have bits filed out for his dropouts on his Echo. Not certain though.

liam n Posted October 10, 2012 Report Share Posted October 10, 2012 I don't think you'll be able to tap it out as the hole won't be deep enough for the tap. As most taps have a pointed end with no threads However I'm not 100% certain, i don't know how deep your hole is...and you may be able to buy a tap with out the pointed end. By the sounds of it you'd probably be better drilling all the way through and using a bolt. but make sure you use knurled/toothed washers to stop the wheel moving aswell.

liam n Posted October 10, 2012 Report Share Posted October 10, 2012 Do you have a video for that? Not yet, just waiting on a frame that needs heli-coiling, preferably not my frame. (touch wood) Quote Link to comment Share on other sites More sharing options...
Rob Leech Posted October 10, 2012 Report Share Posted October 10, 2012 Dan, don't bother getting a tap or a helicoil, just get 2 M6 x 10mm cap heads and liturally screw them in. Will take a bit of elbow grease to do, but you will tap the hole with the bolt itself (the hole is already the correct size to tap to M6 ).
