Hi all,

I have just purchased the front springs and a rear shock from hyperpro, then another bottle of oil as I'm sure 1ltr will not be enough.

When dismantling, what tools were used. The is the 'H' and something that looks like a die holder. Are these required, or have people improvised? If so, what with.

Does someone have the width of the slot in the H. I'm sure that will be easy enough to create.

Many thanks.

1l is enough! 👍

This H is called Damper rod stopping tool, and size between 11 and 12mm is just right. I have 12.3 - 13.3 tool and is slightly to big. Damper rod nut size is 14mm.
1l of oil is just enough.
Tricky part of fitting back spring collar is to hold damper rod in place , as it's dropping down below top of the spring.
Are you using stationary spring compressor?

Hi,
I was following the workshop manual, it doesn't use a spring compressor?

When I changed springs last week, had to use one

OK,
what is it? What does it do? Is the a better picture of one? Can it be fabricated?
 
Sorry loads of questions. But I'm not expecting to do this again so its not something I'd need 8n my toolbox.
