I drilled out some tapered bearing.... So, had a cracked axle on my utility trailer. ran it for months like that, then ordered new axles, new axles had bigger spindles. Mine were 1.372, new ones were 1.375 inner bearing. On the old calipers, thickness of a line. I had assumed common standard sizes.
New axles showed up 3 weeks late, while taking out the old axles, found some springs broken and hidden behind the U-bolts. No one carries replacement springs within a 2 hour drive (in the 1990's every one had them). Ordered replacements, on line, just like the spring supply and replacement shops now do. Another week wait for a 3 day delivery. Installed new springs and axles, got all new hardware with grease fittings. Old hubs didn't slide on. The
BIG spindle difference discovered.
I was contracted to remove and dispose of a 1990 Terry RV tag-along trailer last May. So that afternoon I picked it up, got it home and pulled a hub. Yeah... it worked. So replaced my old hubs and 4 on 9.44" Fayette-Dayton rims with common 6 on 5.5" rims and got the utility trailer road ready and running. During the few days that followed with decent weather, worked on recycling the other Terry RV trailer. Got it down to the frame, now need hubs and wheels to move it.
Last night and this morning, took the Timken LM48548 bearings and sanded the ID bigger. Took a 1/2" wide by 5" long 50 grit belt sandpaper piece, rolled in, placed it in my 1"& 1/8th hole saw, threaded a 1/4" of sandpaper strip out of the one side slot of the cup (slots used to un-thread after use). Sanded until grit was gone on the exposed paper, fed another 1/4" out and continued sanding, several times until the strip either broke off or reached 1.25" long. Then checked it with the scrap trailer spindle. If too small, sanded more. Took about 20-30 minutes per bearing, but cheaper than the $90 per bearing to get the odd combination size. After all, hoping to sell the frame, and would rather make a few than to pay to sell it. Here are a few pictures, have others if you like. The sanding heat melted the grease out of the bearings, so I repacked them before putting things back together.
