L 775 with "issues"

[lewbest]

Hey guys New guy here & just bought a L 775 "basket case." Right side don't seem to pull; jacked up it does a little but grinding noise. I haven't tried the left side yet. When I got it many hydraulic lines, linkages, etc. had been removed, The right chain was taken apart & the right brake disc was off. Amazingly everything but the bolts was there. I got it all back together & found that little transmission is pouring fluid out around the drive shaft. I'd filled it with 90 wt as the owners manual instructed so I either have the seal on on one of the side units leaking or the hydraulic pump leaks. Plan to put a seal in the hydraulic pump first as that seems simplest; read thru the adjustment section of the owners manual (was fortunate enough to get one with the machine) & plan to adjust everything & see if that helps. I'm thinking that there's a problem in that right side unit tho (haven't jacked the left side up to see what it does yet) but one thing i noticed when i tried to adjust that right chain that even with the pin lifted to make it freewheel there was no way I could turn those right wheels by hand. Any thoughts, insite, etc. appreciared! If anyone has a service manual you'd sell (or could make me copies of the pages related to this) please contact me; email addy is lew at lewslittlefarm dot com. Thanks! Lew Best near Waco, TX
