If both press fits are "tight" you will crush the bearing so that it is difficult or impossible to turn. Inherently there are problems with this design, the first of which is thatĬare must be taken not to "crush" the bearing during assembly. The arbor/bearing assembly depends on "press fits" on both surfaces of the bearing, that is the outside of the bearing itself (the OD) is press fit into a cast housing, and the arbor is press fit on the inside (the ID) of the bearing. This would never allow a straight cut of any kind on this saw. The bearing on the pulley side was "shot". My arbor was badly worn and wiggled side-to-side quite a bit, seemed like The trunnions is grease - that is, both trunnions can slide off if the Thing holding the female section of the trunnions to the male section of Iron top and trunnion assembly come right off. Knock two pins from the crankwheel shafts and the cast Four bolts hold the cast iron top to the base, four more bolts hold the trunnion assembly (trunnions,Ĭast housing for arbor/bearings, worm gears, motor mount plate, etc.) to Other than rusty bolts, this was painless. I also called and spoke with technicians twice they answered each of my questions accurately and with no hesitation. Literally within 30 seconds I was told the saw was made in 1975 and that a parts list and user manual would be sent immediately, no charge. Obtaining The Paperwork And Creation DateĬalled Delta at 1-80 and gave them the model and serial numbers. It should also be noted the more I take apart and "make like new" the more I take apart the "marginal" stuff, then the stuff that looked good to begin with starts to look bad. Saw was basically useless as is, but the price was right. However the cast iron tabletop and all steel items were badly rusted (although structurally sound) and the arbor had about 1/8"+ play side-to-side. The mobile base was in good shape, as were the wheel cranks. I acquired an old 10" Rockwell Contractors Saw and wished to make it "run and look like new". This model was the precursor to the current delta 34-444 and I'd imagine most of the items discussed are relevant to similar contractor-style saws.
This document covers my repair-rebuild of a Rockwell tablesaw, model 34-348.
