How to change CB250rsz front fork oil and oil seals?
hi its been quite a while since i have done 1 of these but if the bike has the original forks on it i am sure you can do this without removing the complete fork of the bike, after suporting your bike you can chose to completely remove the fork if you wish, i would first try it without removing the complete fork first, remove front wheel, remove front mudguard and inner stabilizer, keep all bolts together in a safe place, you will need a clean container, to catch the fork oil,(TIP) if you catch all the oil and alow time for it to drip dry you can measure the amount of oil that was in the fork by pouring it from the container into a measuring jug, this will save time if you dont know the specific amount of oil required, to drain the oil you will need a suitable alun key to undo the fork leg/tube securing bolt, you will find this in the lower of the fork leg where the wheel spindle fits, turn the key anti clockwise to undo it, hopefully it will crack loose, if it just spins and doesnt undo you may need air tools to shake it loose, once the bolt is undone secure the fork leg and remove the bolt, the oil will then desperse from the fork, moving the fork lower slowley up and down will help rifle the oil out, make sure the sealing washer is on the bolt or you may have to fish around inside the old oil for it, when you are happy all of the oil has been removed, carefuly pull the fork leg down all the way until it comes of the stanchion, pour any oil into your container, if when you pull on the leg it does not come off this will be because the fork stanchion on your bike has bushes that are fited to it, and not to the lower leg, in this case you will have to remove the whole fork, remove, the dust cover from the fork leg inside you will see a circlip remove this and washer, remove cap from fork top and pour out your oil, and fork spring noteing direction , remove the lower bolt, fix the fork lower in a vice at the very bottom of the leg wher the flat area is, do not grip tubular area,then to remove the seal you will need to push down on the fork stancion to its lowest point, and sharply pull up useing the stancion as a hammer, repeat this untill your fork seal is removed, replace in reverse order, good luck hope this helps. paul
