tapered needle rolling bearings headrace cups for srx

[guest668]

just put new tapered needle rooler bearing headrace cups in my frame and they dont seem to fit flush ..they protrude a little...is this normal? have definatly pushed them down as far as they can go ...go them via wemoto.

From memory mine fitted flush to the frame.

Not on a SRX - but I have had taper rollers sit flush and sit proud.  If the seat is clean before they go in and they are put in square all should be fine do the protrude evenly? Are they the same top and bottom set? - it will be a slightly different spec bearing.  You can seat them by cracking down the pivot nut really tight - but this risks knackering them before you start, can flat the rollers, pit the race, crack the hardening or all three...

the cups seem to protrude evenly by  about 1mm no more.  Thankd for all you comments

always been flush on the srx's i've done.....i'd strip it all out again and clean the area where the cups sit in the frame, then make sure the cups sit well down onto the shoulders in the frame.
not left a spacer in there or summat like that?

First set I had in the Triton were flush, second set were slightly proud.  Stripping and checking would not be a bad shout, but they maybe OK

the bottom cup sits fine the top cup is slightly proud but it seems to tighten up ok have had several goes at taking them out and redoing them ...no spacers in there and all clean inside .

It's a while since i did one, but are the cups that fit in the frame both the same thickness?.....somewhere in the back of my rapidly diminishing # of brain cells i seem to remember that they are different.......might be a different bike/place/time....just a thought.

but if all seems ok, then go for it

[guest668]

i ordered top and bottom seperately so am sure have got right ones in right places...seems to have tightened down ok and movement is good so will see how it goes......again thanks for all your help everyone

Out of interest where did you get them, from memory the bottom race is a non-standard size which is awkward to get hold of.

I sourced them from WEMOTO sown near brighton....the cups didnt look to dis similar to me
