bearings and pinion machining

July 14, 2008 8:24 pm

A couple of days ago, I posted up a bearing inquiry on the Hillman yahoo group.

hey gang,
I’m currently going through the axle in my rapier series 2 project and
am having difficulty locating the correct bearings. The bearings that
came out of my third member are as follows:

carrier cup: Timken 16284
carrier cone: Timken 16150
pinion cup: SKF K26118S/4/J
pinion cone: SKF K26283S

i ordered what we though were the correct bearings from Rick @ sunbeam
specialties. but the bearings that he sent were not correct.

pinion bearing set: Federal Mogul M88010
carrier bearing set: Federal Mogul LM501310

these bearings are the superseded parts from his parts catalog. his
books also list 2 different pinion bearings. my rapier uses the same
bearing for the inner pinion and the outer.

i put in a call to my local bearing house, and am awaiting his search
results. from what i could find on the net, the timken online catalog
shows he carrier bearings but the pinion doesnt seem to match.
i did find a place in the uk that listed the pinion bearing at 200£
each…could this be right?
$800 for 2 bearings… good god that’s more than i paid for the car, LOL

anyway, thanks again for the help

what I ended up finding was the following:

bearing update for those who care… :)

i got the bearings from Kaman and this is what i’ve found.

the carrier bearings (16150/16284)were the same as the ones i had.
the only difference was about -.002″ in the race thickness.

the pinion bearings (26118/26283) were about .005″ smaller in inner
diameter than the originals and again the race was about -.002″ in
thickness…

Since the pinion bearing was slightly smaller in diameter than the original bearing, I chose to skim a bit off the pinion gear so the bearing would not be to tight when installed. The results were better than I had hoped for.
