steering head bearing replacement

[kudzu]

My 1977 GS550 failed inspection (steering head bearings). It seems tapered roller bearings (all balls brand) need stem modification and it looks like it's weld to the lower yoke. Anybody have any info or experience with this issue?

Am I better off with OEM ball bearings.? does anyone know the ball dia. in inches or millimeters? Suzuki part no. 06111-08003 loose balls are anywhere from .94 to 2.95 EACH and there are 18 upper and 18 lower ball bearings.

So, yes, I could use your help and the benefit of any experience you have. Oh, and because this is an inspection thing I don't have the luxury of time. My twenty days runs out September 2, 2013.

Thanks in advance.

you might find they just need stripping, cleaning, repacking with grease and adjusting correctly when refitted

Any bearing shop has them cheap. I put tapered rollers in my 77 550. No problem. No machining at all.

Might just need an adjustment
