Hey gut's I've one pump cylinder that needs resealed (and rechromed) but want to put it off a couple weeks, fairlywell booked next coulpe of weeks. Is it possible to replace the seals (o-ring , backing ring seal gland and scraping ring) and pollish out the scratchs without removing the cylinder to try and buy a little time till Im not giving up to much time with truck down??  Schwing 1200 kit on a 1985.. Its Leaking hyd. fluid in to water box, Don't know exactly how much. Enough that water box over flows after about 200 yds.    Thanks

 Easy to change on Schwing,take out bone,remove flange from rod,remove face from cylinder,inside water box,weld or braze 3 or 4 inch wood screw on screwdriver,turn screw tool into packing,yank it out,replace scraper and o-ring,replace packing ,re-install face,flange,and bone.....should take no more than 3-4 hrs.Turn rod in main cylinder weekly so seal does not get damaged too quickly.With a leak as bad as you describe,moisture has a better chance of entering the hyd. system,it might be a good idea to repair as soon as possible.

SPEEDY; SCHWING SAYS THEY ONLY SELL NEW CYLINDERS AT $6200+ .. DO YOU KNOW A SOURCE? THAT COST VERSES $2000 OR SO TO PULL MINE, MAY JUST REPACK AND HOPE TO GET A COUPLE WEEKS MORE. iVE GOT TWO PROJECTS WITH JUST TWO MORE POURS. THEN IT WONT HURT TO DOWN IT FOR 4 OR 5 DAYS.
