Any one know how to remove the front end bearing from a Picco 26 motor. I suspect its leaking fuel from there. I notice a stream of fuel and dirt build up under the motor around that area.


Much appreciate any assistance

I get a regular buildup of crap on the engine mount on my savage from my force .25 so i think its pretty normal for the engine to do that, ive read i think on here somewhere that someone had a similar problem.

i think i got the same problem as you like their a lot a fuel around the engine, i think it might be you backplate and the fuel has moved around during the day under your engine mount, also have you sealed the carb that could be a problem too. If you have what did you use and where can i get it

My wasp leaked fronm the front bearing. Take the flywheel off and make sure the crank shaft if pulled as far out as possible when you re install the flywheel and tighten the engine nut. After doing this my front bearing leaks a lot less. A little leakage is normal.

thanks guys for ya help.


I have sealed the carb with some Hi temp silicon. And the same goes the backplate. I have run through about 2L plus of fuel so far and the crank is browny colour. everything else looks pretty clean inside. My picco isabout month old.


The Silicon stuff is US brand RTV Ultra black (rate 260c). Used it on previous motors so its pretty good I reckon.


The frontend bearingshouldn't need any silicon..!

Husky,


I have pulled the shaft as far it will go then placed the brass collet on the shaft then the flywheel and tightened the engine nut firm. There is about a2mm gap between flywheel and front bearing, it wont go anymore.


If its the norm for a little leak for Picco/wasps I could live with it.


thanks

Sounds all right, Just make sure the collet is pushed as far onto the shaft as possible. You cant use silicone on the bearing, its impossible

Yep Ultra Copper is good, used it on the ol' motor bike - no problems at all.
