Goulds 3196 shaft dimensions by frame

The 5 Goulds 3196 power ends, ST, MT, LT, XLT and X17, with the journals, bearings, seal sleeve seat, coupling end, bearing span and overhang each replacement shaft is dimensioned to, as the matching catalog part loads into the configurator.

The 3196 frame is the power end: ST, MT, LT and XLT, and the X17 for the 17-inch sizes. The frame fixes the shaft; the hydraulic size does not, so identify the frame first, from the nameplate or from the bearings in the first table.

Journal diameters and bearing numbers come from the bearing-fit and bearing-type tables in the Goulds i-FRAME installation manual; sleeve, coupling, span and overhang from the Construction Details in the brochure. Both journals are cut to the k5 bearing-seat fit, the light interference the manual specifies for a rotating inner ring. The X17 coupling diameter and key, bearing span and overhang are not in the published tables and are marked est. in the second table: estimated by ANSI analogy; confirm against your shaft.

The threaded impeller nose on each catalog part is representative, sized under the impeller register, because Goulds does not publish the thread. Every dimension stays editable in the configurator and the drawing title block stamps the source frame.

Bearings, journals and seat fit by frame

Journal diameters in inches at the finished size. The fit is the ISO 286 class with its deviations from nominal; the bore in millimetres is the bearing bore the journal is sized to.

Seal seat, coupling and axial dimensions by frame

Inches. Overhang is impeller end to the inboard bearing centre; span is centre to centre of the bearings. est. marks a value that is estimated by ANSI analogy; confirm against your shaft. The nose thread is representative, not an OEM dimension.

Goulds 3796 and Goulds 3996: the same power end

Goulds models that mount the 3196 power end and ship the same shaft. Each row is dimensionally identical to the 3196 frame it names.

Reading the frame off the bearings

6207/7306 is the ST, 6309/7309 is the MT, 6311/7310 is the LT, 6313/7313 is the XLT or X17. XLT and X17 share a pair; the seal/sleeve seat separates them. The inboard radial bearing is a single-row deep-groove type; the outboard thrust bearing is an angular-contact type with a double-row alternative of the same bore, so a double-row number on the old bearing does not change the shaft.

What is representative, what is estimated

Every value in the first table and every unmarked value in the second is from the Goulds tables. The impeller-nose thread is representative. The X17 coupling diameter and key, bearing span and overhang are estimated by ANSI analogy; confirm against your shaft; the part page shows the same values as configurable starting points.
