DO NOT USE 24mm 0r 25 mm SOCKET THEY WILL DESTROY THE SEAL--USE A 3/4 INCH PVC COUPLER-- A $40.00 LEARNED LESSONOriginally posted by JM317
I just replaced mine in about 10 minutes and it was the first time I've done it. Once the impellar is unscrewed and removed, pull the old seal out with some pliers. Tap the bearing and seal out with a screwdriver or socket. To press the mech seal in, just use a large bench vise and 24mm socket. Place a piece of wood or something behind the back side of the case of course to keep the back from getting damaged by the vise. Place the socket's hollow inner side directly over the edges of the mech seal with the back side of the socket against the other side of the vise. Make sure everything is lined up and even. Crank the vise down. Install the seal and bearing/backside of the impellar seal with another socket (I used a washer inbetween the socket and seal when tapping it), install the impellar again and you're done.
THANK ATV GODS THEY HAD ONE IN STOCK -ONLY AFTER USING OLD SEAL ON THE IMPELLER TO PRESS IN THE MECH-SEAL
i just purchased a new mech seal, bearing, oil seal and all gaskets including the metal one shipped to my house for $50 from service honda all oem / i have not replaced any of it yet and not sure i wanna take advice from anybody on this thread after reading it!!! sure does seem to b alot of controversy over what works and what doesnt! lol surley it cant b that difficult!
Go Big or Go Home!!!
With the correct tools its a walk in the park. Without the correct tools its like walking barefoot in the desert. I have seen many people destroy the $35 mechanical seal.Originally posted by Grande Huevos

The best advice is too use heat. The bearings and seals will come out much easier. 250 degrees is good.
Last time I was pressing in the mechanical seal I broke the water spigot. If you heat to 450 you can even get the spigot unscrewed.

I see stuff whether it exists or not

the original how to works, everyone has their way and their two cents about how to do it. The way I explained many years ago, allows you topressin the metal seal with out a special tool and minimal risk of wrecking the seal.

I just let a friend replace mine cause I thought he knew what he was doing...he had did his before, well he tapped it in with a 1" pipe. It seemed like it went in real smooth. Well after I put it back on it was dripping from the coolant hole under the waterpump. Anyway I purchased a new seal AGAIN and did it myself with a shop press and a 3/4 white PVC cap...yes platic cap and it worked awsome. I cleaned the area for the mechanical seal good with steel wool and said a few prayers! It works awsome. Thanks to AceCarlos for help with advice too.

Getting back into things, actually, picked up an old beater, along with a few new friends that are eager to get into the sport.
I'm looking at designing a new ignition system, going to see if I can marry a CR250 and a stock 250r ignition together, should be an interesting project.

for the power of the CR and lights of the trx?
if it doesnt work out just go with the ricky stator, stator, flywheel and rectifier
the best way to go to get what you want if im right as into why your doing it, try and get a PVL digital ignition that u can use lights with.
