Re: How to remove the hydraulic hose on the boom cylinder on a 450c loader?

That is correct, the big cylinders that move the main loader arms. I just dont know how to tighten the hose that goes on the cylinder, the end that connects to the pipe end that is up in the pocket. I cant get those pipes out. Crows foot? Homemade crows foot type tool??

Re: How to remove the hydraulic hose on the boom cylinder on a 450c loader?

Digging up an old one... I replaced both of my boom cylinder hoses last fall (left side). An old JD mechanic told me no need to remove the steel pipes as the o ring on the new hose end will seal just by tightening the other end of the hose before securing that end.(after hours of trying to get those...
