Hi and a big warm welcome from UK.
I have now tensioned my b52 drive chain to the max and was open to suggestions which steps to take next? do i
replace the complete chain ?
remove a half link and re-pin chain back together ?
replace complete chain and both sprockets ?July 23, 2016 at 11:52 pm #16234
If your sprockets are still in good shape I would just replace the chain with a new one. I wouldn’t just remove a link, because if your chain is stretched that much it will wear your sprockets out faster.July 24, 2016 at 10:55 am #16241
Purebeats how many K’s on the odometer?July 25, 2016 at 12:26 pm #16247
Hey and many thx for the response , totally agree and will carry out my next maint procedure as your options stated, I will only at this stage replace the complete chain, lol looking forward in having to count the total amount of links , coz aren’t these chains sold in different lengths ,, oh and not forgetting imperial sizes, oh not looking forward to this, !! Can’t see spec in sub cmm (July 25, 2016 at 12:28 pm #16248
Hi Roger and big thx for interest, will enter the Km / mile digits tomorrow,July 27, 2016 at 8:35 pm #16268
Purebeats.. to check the chain for wear.. apart from the obvious stretch limit test..
Try lifting the links on the sprocket to test whether the force is being shared between the maximum number of teeth on the cog. The worn/stretched links will lift off the cog easily with all the stress being put onto only the first link. Obviously this accelerates wear and eventually this is evident as distortion of the teeth which become hook shaped. This is a common issue with chain driven bikes and usually it is recommended to replace the entire drive train. I would guess(since I have only recently joined this illustrious squad of bomber pilots) that the bike has done 10,000Ks or thereabouts if the drive train needs replacing. A photo of the sprockets would be good. Interested to know how you go.. Having said all that I’m not sure what the stretch limit is.. Of course you could probably run the teeth down considerably with the only issue being possible damage to the upper surface of the swing-arm.July 29, 2016 at 7:55 am #16283
Many thx for your reply, my B52 has now covered 511 km’s , so I ve decided to replace the whole chain. One thing though that I wanted to point out is when tensioning your chain , be sure to adjust your rear brake calliper’s ,as the more tension applied moves the disc out of the brake callipers.upon receiving a new chain I will attach photos of chain length differences.July 29, 2016 at 10:50 am #16287
Please confirm the odometer reading..That’s not a lot of Ks.. a bit surprised the chain needs replacement..
Also a pic of the sprockets would be helpful…
And thanks for the tip..August 1, 2016 at 2:16 am #16313
Gee I have 7500 miles on my original chain, and it’s in like new shape. Maybe I should pedal harder or something.August 1, 2016 at 11:15 am #16318
Hi , well it is what it is , and yes I am wondering why I can only do 511km compared to your 7500???, here’s some stretched chain and new chain( fitted today) photos…August 1, 2016 at 11:21 am #16319
cont……August 1, 2016 at 11:24 am #16320
ok , completely failed in attaching these pictures…lol too big files
what’s the best way of doing this?August 3, 2016 at 4:34 pm #16344
You need to host the image somewhere and then copy the link address to the ‘Add/Edit Image’ box.
Very interested to see the amount of stretch and the condition of the teeth on the cog. If the teeth are not hooked then they are not worn. Did you ever lubricate the chain?August 3, 2016 at 7:08 pm #16346
Hi, the main and freewheel sprockets are all good, I lubricate the chain before every ride and would say I maintain to a very high standard, as I renture more into this frequently routine maintenance, I will post some other found technical flavours that with a slight twist will prolong the likes of this beautifully crafted bike.
you got any suggestions on sites to post pictures?August 3, 2016 at 9:43 pm #16347
