    Replacing Seals in Dipper Ram on a 2002 JCB 214

    Did this on our JCB 214 on a remote island in the Bahamas. Pipe wrench and a long bit of tube. I marked the start point on the nut so when putting back on and tightening you have a reference point. I have done the bucket ram, all the rams on front bucket and stabilizer rams this way.

    Just pointing out that it can be done out of the workshop if you have some appropriate tools with you. Cylinder nut on the CAT was a tad smaller than 6" maybe 5 7/8"
