power gear hydraulic jacks, 1997 bounder 36s

Powergear makes rebuild kits for their jacks. You will need a heavy duty Bench Vise and possibly a torch to break the old collar loose. The rebuild kits come with a new lower collar that has a grease zirc. I would buy the rebuild kit and then let the local rebuild shop install if you do not have the tools to do the job. Powergear jacks also have springs. Some are internal and some are on the outside like you have. You usually measure the length and diameter to determine which kit you need for your jack. Unless you still have the yellow p/n label still legible on the jack. Doug
