Progressive spring install... HELP!

[kevin-vic-b.c.]

I got my progressive springs yesterday, I am slightly confused when it comes to the fork oil level.

First thing is to block the bike up so the front wheel is off the ground, then I need to fully compress the forks and measure to the top of the fork oil.

 

I am sure there is an easy way of doing this but I am easily confused and this has got me.

I do not have the bike apart yet, I just need to know what I am doing before I take it apart.

 

Thanks everyone.

They are easy to compress once you get the caps off.

Doing fork seals while you are there? If so you will have all the old oil out, or you will have to drain for a while. There a screw at the bottom of the tubes to drain fluid. The forks need to be fully collapsed, then fill with fluid then springs, with pre-load tubes, and caps. (carefull not to cross thread, fine threads) :canada:

The Progressive Instuctions state:

 

Oil level should be 5.5 inches from the top of the tube with the fork completely collapsed and the spring REMOVED.

 

So top cap off, spring out, push lower fork all the way up and THEN measure the oil level.

And don't forget to PUMP the forks to get all the air out of the bottom.

Since the fork tubes are at an angle, is the 5.5 inches at the front, back, or middle?

I don't think it's that critical. However, I used a square that was nearly the width of the inside of my fork leg to measure the oil level. The oil level would run across the face of the square and I used the center as my reference.
