Farmall H Steering Bolster

David Pommert · Oct 29, 2009

The bolster seems to make a clunking sound when driving the tractor. Assumed sleeve bearing was worn. The new sleeve bearing seems to be as loose as the orginal. How much clearance should the new bearing have relative to the bolster?

The clunking sound was probably the thrust ball bearings on the bolster shaft.

Lot"s of wear on the bolster shaft occurs thru the years, not just the bronze sleeve. What I did to mine when I rebuilt my 40 H was to have the bolster shaft welded up, then I turned it down to just nicely fit the worn bushing that was in the housing. I allowed around .005 play. That bushing is not easy to get out.

David, If the shaft is worn, build it up as Dave suggested. If the sleeve is loose in the bolster, you can add shim stock between the sleeve and bolster casting to reduce the free play. The less slop you leave, the better you'll like it. This happened on the bolster of my '51 H and I found that a previous owner had taken a chisel and beat the tar out of the bore in the bolster in an attempt to make the sleeve fit. It was extremely unsatisfactory as the sleeve didn't have firm support and wore away quickly.
