Shock rebuilt
« on: July 18, 2014, 17:47:31 »
Together with an overall check & replacement of some parts, I had my rear shock dismantled, arranged and rebuild. I considered it would be enough for the km left to my bike.

It turns out it was a good idea, because there was a part inside that was half broken, so I was in real risk of "getting seated" all of a sudden!

In its 185000 km, all I had done was to replace the spring for a Hyperpro one some years ago. According to some expert, this stronger spring shortened the life of this half broken part.

This part is an aluminium cilinder, like a pot withoud lids, with two circulars "carvings", one inside and one outside, where spring hold, and serve for the preload adjustment.
This expert crafted a new part, but with the carvings at different height, so that there's two thinner places instead of a one much thinner one. With this design, position 0 of preload adjustment is equivalent to position something in the old one, but this is no problem considering my "over 60 kg" weight  8)

To summarize. If you have stronger springs, you are risking an internal break of the schock in the long run.

Greetings,

Josep

An old engineering lesson from the early days of 'tuning'. Components must be compatible to spread the load, weakest link and all that.
More horsepower, break the clutch: stronger clutch, break the chain: stronger chain, strip the gearbox etc. etc.

Pleased you are prepared for the trip Josep.

Thanks to you all, men!
This is my last visit in a couple of weeks. We are leaving tomorrow, so unless a curtain of rain stops us (this is a possibility   ??? ), we'll be reaching England by Tuesday.

See you,

Josep
