A 2007 Puma 240B lost adhesion of the turcite (Rulon) strip on the X-axis box ways, requiring full disassembly, re-gluing, and re-scraping of all way strips; the same machine had also developed worn ('whiney') spindle bearings. A forum expert noted Doosan lathes are known for this turcite adhesion failure.
Cost not yet verifiedThe same 2007 Puma 240B with failed turcite way liners had also developed audibly worn spindle bearings, with a full spindle bearing rebuild estimated at $7,500-$20,000+ on top of the way-liner repair.
Cost not yet verifiedOn a Puma 240LC, the turret stopped indexing tools on the spindle centerline; when re-tramming the turret in X and Z did not fix it, the diagnosis was a bent indexing shaft or camshaft inside the turret requiring replacement.
Cost not yet verifiedOn a Doosan/Daewoo Puma 240L, three positions on a 10-station turret showed a small reverse 'kick' of the servo during lock, persisting even after disconnecting the mechanical belt and recalibrating the encoder, pointing to a servo amplifier or encoder fault rather than mechanical wear.

From the research record
- MARKET (2 real dealer listings, 2026-09-07): $29,900-$29,900, median $29,900. Exact-model listings; Claude spot-verified a sample.
- RISK (2026-09-08, high): Way covers / turcite (Rulon) box-way liner: "the machine will need to be completely disassembled. New turcite glued on, and then scraped." https://www.practicalmachinist.com/forum/threads/doosan-puma-240-turcite-strip-replacement.365012/
- RISK (2026-09-08, critical): Spindle bearings: "whiney spindle bearings" https://www.practicalmachinist.com/forum/threads/doosan-puma-240-turcite-strip-replacement.365012/

- RISK (2026-09-08, medium): Turret PRO-MOTION servo / encoder: "the turret makes a small movement towards the back to lock (a small reversal of the servo's rotation)" https://www.practicalmachinist.com/forum/threads/problem-with-pro-motion-doosan-daewoo-puma-240l.433465/
