|   when installing a 700-800lb spring... | puffy
Jan 9, 2003 10:13 AM | | what's the trick to getting the spring in and preloaded properly?
do i need a special tool? can i do the job myself? it seems a 700lb or higher spring would be difficult to compress by hand, and once it's in ... do you use a wrench to twist the preload ring?
thanks

Jan 9, 2003 11:01 AM | | I have a 700 or a 750 (can't remember) on my Vanilla R. I don't have any problems turning the preload ring. I usually grab both the ring and the spring and twist both. If I remember correctly, I think Fox only recommends one turn of preload. |

Jan 9, 2003 1:29 PM | | until it tops out, hold the spring up against it, and fiddle the slotted lower spring support off of the shaft. It may be quite tight getting the slotted disc off because those heavier springs are very long (you do have a Fox spring recommended for that particular shock/bike, right?). It is like one of those tavern puzzles. You will need to have the rebound control turned all the way in to slide the spring off. Reverse the process to reinstall. If the spring is too long to get the lower disc off, your spring is the wrong size. You may be able to compress the spring a tiny bit by grabbing it in the edge of a vice, though you should not have to resort to this.
Once the new spring is in, turn the preload adjuster down agains the spring so it just touches. Now turn the preload down onto the spring 1 single full turn. This is the "zero" preload point. Do not exceed 2 additional turns of preload.

Jan 12, 2003 4:01 PM | | I'm using 4 turns preload on my 700# on my Vanilla-R. It's far from coil binding. I calculated it would take about 10 turns to coil bind without the rubber bump stop. The shock doesn't have any topout clunk with medium rebound adjusted.
It feels great when riding.

| That according to both Fox and Turner | Tscheezy
Jan 12, 2003 10:09 PM | | when I asked about my Vanilla on my XCE. I think their point was that if you need more than 2, your spring rate is too soft. I suspect, however, that they are afraid of coil binding and some shocks may suffer from that if you go much past 2 turns (mine would), so as a blanket policy, they say 2 max. You compress the coil about 0.1" with each turn, so that can add up fast. Some folks run way too soft a spring and just turn the preload collar down half an inch.
Just regurgitatin' here.
