|  Z1 Freeride SL oil level? revisited? | keen Jan 10, 2004 11:19 AM | | I did a search on the 03' Z1 Freeride SL and found many posts on volumes, levels etc. I contacted Marzocchi yesterday and was told by two techs to compress the fork and lower the rods (L/S as much as possible due to the top cap)and set the oil @ 55mm from the top. They actually suggested oil level vs. volume to set-up the fork. Two points of mention 1) In all the posts I read none mentioned 55 mm from the top 2) My fork out of the box had far less oil than 55mm. Any definitive answers for the oil level? |
|  Zoke is W-R-O-N-G | SDizzle Jan 10, 2004 4:59 PM | | I don't know by how much they're off, but I don't think the numbers they gave you are right. It isn't the first time, so don't worry about it. They make good products, they just know know anything about them!
Now, measure by VOLUME. The merits of this have been discussed before, so I won't go over why (a search will reveal the answer)--suffice it to say, it's much more accurate. Again, 85 ml right, 50 left. |
|  FWIW, I did it the SDizzle way, and the fork feels fine. | Tscheezy Jan 10, 2004 11:47 PM | | Zoke sent it out with about 10ml in the left leg. Those dillweeds. Anyway, using SDizzle's 85/50 volume I get close to full travel, the dampening and ECC work as they should, and things are smooth. Seems correct. What more can you ask for?

|  Actually 55mm should be fine.... | Ventanarama Jan 11, 2004 6:47 AM | | 55mm from the top measurement should work just fine. The cc's numbers in their tech manual and CD are wrong, but those will result in much higher levels than 55mm from the top (higher as in more oil, ie: lower mm measurement. 55mm works fine and should get full travel. Any higher than about 50mm and you probably wouldn't get full travel. I do agree that using volume is the easier way though.

|  re : Actually 55mm should be fine.... | keen Jan 11, 2004 8:53 AM | | I am sure that with either volume or height measurements I can achieve *satisfactory* results. What bothers me is all the conflicting information on this fork. Can't Marzocchi @ least correct their website? I have a brand new fork that I thought would be a bolt on and ride. I shoudn't have continue R&D for Marzocchi. I am almost tempted to sell the SL in favor of a coil, @ least there isn't conflicting data w/ that fork. Thanx |
|  Marzocchi can't get the oil height/volume..... | Ak Dave Jan 11, 2004 9:11 PM | | correct on any fork. I've owned a few and all were off at least a bit.
good luck,

|  How about the Z1 Coil?? I was doing mine last night and woah... | Bikezilla Jan 12, 2004 8:53 AM | | I had 5.5cm before I started, and almost half that when I refilled according to spec. The Z1QR20 Technical Service manual (not the useless owner's manual)suggested 155cc in each leg.
I let that puppy drain for more than a day, and pumped the heck out of the rods and stanchions to try to get as much oil out as possible. (Done upside down and right side up) I'm pretty sure 155cc didn't come out. I also pumped the fork and rods quite well when I refilled the fork, tapped on it quite a lot to shake loose any bubbles and kept pumping the rods until they felt full. (Pumping and filling in stages)
Also I have to say the internal component arrangement does not seem at all like the manual indicated. The manual shows the round washers go beneath the springs. When I disassembled the fork the washers was on top and quite frankly, I don't see why it would go under the spring as most of the pusher nut would slide into the spring without the washer on top and then wouldn't sit very flatly. Also there is a 4-point star washer on the rod to hold the spring bottom in place.
I would call 'Zoke but it seems from the threads here that the techs are quoting the manual, and if the manual's wrong, then why bother?
About measurements: I poured exactly the same volume of oil in each leg and got rather different measurements. The left (ETA) leg is higher. Now I really did try rather hard to get all the oil out of both. So my question is what good is doing your fill by *volume only* if you can't be sure if you got all the oil out and/or each leg fills differently anyway? Is my measurement method flawed? I take a straight rod and dip it into the stanchion until it just-barely touches the oil surface, then measure the length of the rod, where my fingertips are holding it right at the lowest point on the crown opening.

|  Z1 SL ONLY!!! | SDizzle Jan 12, 2004 5:27 PM | | I couldn't tell you what the volume for the coil model is; my guess is the springs take up quite a bit of space, and the ECC dampers are a lot different than the ETAs. Also, the dampers/negative chamber and rebound chambers take different amounts of oil, and that's why the numbers are very different per side.
I got my volume measurement from a fork that had it's internals coated in oil, and was emptied as best I could. Provided the volume measurements are the same, and my process is the same, everything will come out fine everytime. |
|  Oh yeah, I know they're way different. | Bikezilla Jan 12, 2004 7:13 PM | | Yeppers, many differences. I'm sure even the ECC rod is a different volume, let alone the air chambers and such.
I was wondering if anyone had info on the oil levels/volumes for the coil Z1.
Larry and Warrguru suggested 50mm that seems pretty good.
Thanks! |
