do you need to change oil on a devilbiss xr2500

My connecting rod bearings are press fit, not held with a convenient screw clamp. I believe the ones I removed are NTN 6203LLBC3 (ie size 6203, dual rubber 'non-contact seals', C3 radial clearance). I also replaced the bearings in my connecting rods. I consider it likely that bdk-parts is selling a genuine kit and that neither vendor was responsible for the o-ring mistake (I have since bought another two from bdk-parts for spares, and the included o-rings are correct). Otherwise, both kits seem identical, right down to the box they're in. Unfortunately, one kit came with the wrong size o-ring, but since I had lost track of which kit had the wrong o-ring, I sourced a replacement myself (AS568 -039, silicone, no issues to date). In fact, the lip enforces the proper entrance of the ring or connecting rod assembly from only the head end.Īt first I ordered two K-0650 kits, one on ebay from bdk-parts (shipped for $35 & tax), and another through a more 'proper' channel (at greater cost). Neither the added length nor the pronounced lip seems to cause trouble on this pump. Hopefully the new finish is at least as durable as the old. DeVilbiss pumps AC-0051 & ACG-4000-1 also call for K-0058.Ĭompared with the cylinders I removed (presumably the originals or from a K-0058 kit), the cylinder in this kit has a different finish, is longer, and has a more pronounced lip at the connecting rod end. The correct cylinder/compression-ring kit for this pump is the K-0058, which seems practically unobtainable at this time. The K-0650 kit works on a Sears / Craftsman 919.152813 air compressor, which is a rebranded DeVilbiss using the AC-0102 pump. No matter, because Garage Journal is probably a better place for this anyway. It seems that the ebay content moderation system is quite touchy (supposedly it searches for forbidden content with no consideration for whitespace!). I had originally written some of this as an ebay review for a K-0650 cylinder & ring kit I bought, but ebay wouldn't display it. This is an informational post to assist others repair their Craftsman / DeVilbiss oil-free air compressors.
