Just how stuffed is my drivetrain?

[Shepherd]

therein lies your problem!!

 

Yes if you look at the pic its item 7, that step must face inside. You need to turn that bearing around.

 

Pressfit BB is actually easy to replace with a few homemade tools, I've changed mine twice already.

 

Please share these home made tools...

 

I take my crank off regularly to clean old grease and dirt out and reassemble with new grease.. But dont have a bearing puller and dont want to hammer things out...

 

Looking forward to your feedback.

 

Kind Regards,

Tim

First off, your drivetrain's shot. Somewhere in the tech section there's a document called "Everything you ever needed to know about chains" or some such. Find it and read it, especially the bit about how to measure chain wear. If you know when to change a chain, you may never have to buy another set of cogs again.

 

Second, if that spacer makes your BB seize, it's not meant to be there. Don't compromise on recommended torque just to make it work - you'll either wreck the bearings or the spline, and then it's time for a new crankset too. If the chainring doesn't rub on the stay, there's enough clearance.

 

This one?

some pressfit bearing don't like to be removed and the plastic casing around the bearing tends to disintegrate when you take it out

This one?

 

That would be the one. Quite a read, but definitely some stuff worth knowing in there - particularly how to measure and how to clean.

Definitely a great read about the chain....

Ok cool thanks, will just go back to the specialized shop and have them change the bearings... normally a 10 mim job...

 

I do regularly take crank off, clean and re grease...
