fix oil leak from blower

i have a Kobelco blower that started leaking oil out from the top pulley. I am going to pull it off and check. Any ideas as to what is leaking, and hat could possibly cause it?

Also, There is a spring pressure relief in the blower housing at the front. Should it have pressure after a pass when pressed in?

How do you check the oil level in the blower?

 

The blower should maintain pressure. If not, your losing/lost the seals..

 

which seals are you talking about?

 

snout seal is leaking as for how much oil it depends on which one you have, pull the front drive off and put a new seal in it,your parts store will have it. Dave

The blower is a Kobelco 8-71 Superman with a 5" snout.
How do you know what is full?
do you fill it by removing the pressure relief valve and using it as a fill hole?
What type of oil goes in the blower?
Any tricks to removing the snout?

Thanks guys, just really new to this blower stuff.

 

we always run what ever we use in the motor and what I always do is in the bottom i put a drain in it 1/4 pipe plug and a fill in the top and a full plug in the middle in the front

3-D I just had the same problem with my superman .
I ordered a new seal from Fowler engines and changed it my self.
A snout seal isnt that bad a job too change but you will need a press to do it.
If you aren't mechanical and dont have a press you could send it out.
Jeff at http://www.jdfperformance.com/ is just north of Dallas and should be able to fix you up no problem.
Every one has their own opinion but I like to use a good quality 2-stroke synthetic eingine oil in my blower case .If you tear up a rotor seal and push your blower case lube into the engine the 2-stoke oil will burn and not detonate you engine.

 

I just replace my snout seal and bearings. Pretty simple process. We set the blower back 2" and put a 2" spacer on the snout. 12 runs on the blower and the bearings & seal were fried! The extra 2" put way too much stress on the bearings. Had to go to a 7" snout to fix it properly.

 

Jeff at JDF fixed me up today. Thanks for the replies, and a MAJOR thanks to Jeff for getting me going so quick.
