drive train.

remember i explained the extremely dangerous concept of ‘while i’m in there‘? the last part of my elaborate and well thought out plan to convert my favourite trail weapon into a slightly renewed favourite trail weapon. the last missing pieces were of course the new cassette; same as the old one, an x01 10-42. there…

rollercoaster 1.

ever since i came to australia i have been looking for an opportunity to race enduro – on a motorbike. while i arguably was never any good at it i always liked that kind of race. firstly it (mostly) a race against the clock, not against a bloodthirsty mob of other guys with apparently nothing…

pretty chewed up.

the drive train. it looks a bit … used. i’m not complaining. the chainring, the chain and the cassette are actually consumables, I guess with the kind of power my little legs put out they are just wearing really slowly, but given most parts are probably 2 years old it’s ok to see signs of…

threads.

how hard can re-packing your santa cruz nomad link bearings be? not very, right? there is even a grease nipple! well … someone in south east asia obviously did not really pay attention when they machined the threads in the frame and the swing arm (or forgot to change a tool as per the schedule).…

while i’m in there.

it all started with a bit of time & nothing better to do on a sunday afternoon. the fact that the rear brake had been gripping the disk asymmetrically has not really ever been a problem but being a bit of a perfectionist i was determined to make sure the pistons all moved synchronously. a…

more problems.

after i had replaced all the bearings i thought it would be a 5 minute job to put it all together again. i was wrong. this is one of the axle bolts through the lower links. they both look pretty much the same: ruined threads. not sure what happened here, but someone must have damaged…

press.

now that the bearings are out i’s time to get the new ones in. unfortunately it is difficult to find the special tools required to professionally press in the new bearings … so a little ghetto engineering is on the cards.good thing the 6900 2rs bearing internal diameter is pretty much precisely an m10 thread. the…

what’s cooking.

there is this problem with the uncharacteristically rough roller bearings in the linkage of my favourite nomad. the old bearings have to come out before the new ones go in, but there is no way to get any purchase on the outer race and once you start hitting the inner race the whole bearing just…

sticky situation.

when it comes to bearings sticky is definitely not what you want. and those bearings are very, very stick. unfortunately. see those grimy rusty and overall pretty gross bearings in the lower link? then again this is not a difficult problem to fix, i need 8 bearings and a few seals, a bit of grease…
