Replacing fork seals and need to know amount of oil for outer fork on a twin cartridge tpye fork rm250 2005

Dave, I usually measure the amount of fork oil that drains out of each fork and replace with that same amount. In my experience this is not necessarily a critical spec. All bikes are different, however. Many owners and mechanics will experiment with differing amounts and weights of oil. You may consult your dealership and try to get within a couple ounces of spec.

Hi,,,,,,fork seals are to stop oil coming out of your forks,,,,if your forks have oil on them ,then the seals need replacing.(you cant fix them)


hope this helps

forks need to be removed,and disasemble,and cleaned,new fork seals,reasembleb fit new seals, refit damping cartridge,fill fork with 5w fork oil upto 120mm from top,refit spring, refit fork cap

Well, when you take off the fork make sure you empty it first before anything else then make sure that the fork pressure spring is released before changing the seals. The fork oil amount should be no more than 200 cc or no less than 190 cc

try about 250-350 cc

You have to get the book on this one to redo your forks, If you are replacing a seal or just topping them off, you shouldn't have a leak, but the fork oil is special from any bike shop and the amount is kinda critical, so find a book with the amount of oil needed. Usually you would remove the forks, lay them in a big long pan, pull the ends, and pull the springs and seals out, squeeze them back together and fill them with oil. Hope this helps.

The forks hold 286ml or 9.67 US OZ of oil, best would be to use hydraulic oil.
Good Luck.

NOTE:
Refill front fork oil up to the top of the outer tube so that bubbles
are visible while bleeding air.
• Refill specified front fork oil up to the top level of the outer
tube again. Move the outer tube up and down several strokes
until no more bubbles come out from the oil.
• Keep the front fork vertically and wait 5 – 6 minutes.
NOTE:
* Always keep oil level over the cartridge top end, or air may
enter the cartridge during this procedure.
* Take extreme care so as to pump out air completely.
• Hold the front fork vertically and adjust fork oil level with the
special tool.
NOTE:
When adjusting the fork oil level, compress the outer tube fully
without the fork spring.

Each fork has an outer dust seal, and an inner seal inside of that. Dirt gets between the seal lip and the fork slider and causes the oil to escape. The fix is to have them (Both sides) replaced. You need a fork seal driver tool (Size specific for the size of the fork) and something to measure out the oil amount. It's not an easy job, if you have never done it. Also... if the oil has never been changed, it's due.

hi,replacing the seal is quite easy,although it will sound complicated,jack up or lift the bike off the ground so that the front wheel is in the air(about 12-14 inches should be enough,remove the front wheel from the bike,remove each fork leg,this is done by undoing the bolts(4 on each leg)the front fork is quite easy to work on just do one at a time,remove the dust cover from the top of the staunchion tube(larger diameter tube),beneath that dust cover you should see a retaining clip that holds the seal in place,remove the retaining clip(and dont lose it),the seal is now ready to remove,the easiest way that i know to do this is to force a screwdriver through the body of the seal,you may need to hit the screwdriver with a hammer as some seal have a tin backing plate,put a hole through the seal on each side of the fork leg taking care not to damage the chrome of the fork leg,then use the screwdriver to lever the seal out of the fork leg,to reinstall the new seal,put a smear of grease or oil around the outside of the new seal,slide the new seal down the fork leg and seat it squarely into the fork tube,very carefully tap the new seal into place being very carefull not to damage the outer surface,i use a small piece of dowell type timber to do this as the wood doesnt damage the seal surface,i use a small ballpeen hammer to tap the wooden dowell,once you have the seal seated down the tube you should be able to see the groove for the retaining clip,reinstall the retaining clip making sure it is seated corectly,replace the dust cover,if you are going to replce the fork oil or top it up do this once the fork leg is back in the bike,repeat the whole procedure for the other fork leg,once you have done the fork seals reinslall the fork legs back into the bike and refit the front wheel,to top up the oil in each leg,simply undo the large cap on the end of the fork leg,you may have to remove the handlebars to do this,be carefull as the cap will be spring loaded and can easily fly off if you are not ready for it,top up or fill with the correct weight oil for your bike(normally a 10w oil),check with your local honda agent for the correct quantity,normally between 400-500 mls,this all sounds quite complicated but is actually quite easy and can be done with a minimal of tools,each fork shold take about 1/2 hr to do...hope this is a help to you
