Re: Converting my GT Mohawk hubs to sealed cartridge bearings

That one actually looks like a factory sealed hub.  You can tell because the rim around the bearing hole is thicker.

Little hard to tell on my phone but looks rounded where bearings would sit. If it is then it's unsealed

Re: Converting my GT Mohawk hubs to sealed cartridge bearings

My bullseyes always had free play....still do! but my loose rythym hubs are causing me problems and i want to switch to sealed as I'm having trouble sourcing decent quality replacement cones. Last set I bought lasted 1 lap of the track and major graunching noises forced me to head home.  Anyone converted  loose rythyms to sealed?

Re: Converting my GT Mohawk hubs to sealed cartridge bearings

Well I had the noise problem on a looseball hub I had, I went to a small cone and it fixed it no issues, but if you want to swap your rhythm hubs the same applies as mohawks, just need to use a micrometer to measure what size bearing you need, I'm pretty sure rhythm hubs use 6000 on front and the rear non drive side, and the drive side uses a 6200. Don't take my word though and double check with a micrometer.  cool

Re: Converting my GT Mohawk hubs to sealed cartridge bearings

Thanks for the advice. I'll try smaller cones first and if that doesn't fix it I'll go down the sealed route.

Re: Converting my GT Mohawk hubs to sealed cartridge bearings

The nice thing about it is, if you don't go too crazy, all you need to do is unbolt the axle and pop the bearings out and you have 2 normal hub shells again, minus the old destroyed loose bearing cups.

Re: Converting my GT Mohawk hubs to sealed cartridge bearings

I'm starting the Superlace Conversion. Trying to determine the best way to remove the ball bearing cups.

Some good ideas here and unfortunately too much lost information and the photo bucket dick head strikes again.

Re: Converting my GT Mohawk hubs to sealed cartridge bearings

So essentially what we're saying is that GT bored them all for cartridge bearings as a way of streamlining manufacturing, but then stuffed loose ball into some as a way of filling a product line.....right?


Hutch Fun Facts: All main line Hutch's with digits only S/N (no letters or baseballs) on the rear drop outs were US made and had their dropouts stamped between late '83 and '86.  Obviously the frame manufacture would occur slightly after that, even if they just threw 'em in a bucket randomly.  There is an obvious date code in that the first 2 digits seem to be the month and the 3rd digit is pretty obviously the last digit of the year running from '83-'86.

Re: Converting my GT Mohawk hubs to sealed cartridge bearings

Not exactly... these bore holes are 24.5mm I haven't found anything to match. I've searched for 2 weeks now. The axle was standard size hole

I guess I wonder if what we're saying is that it's a bit sloppy good enough.

I know that Suzie did this with SOME of their hub manufacture runs.  And I can prove that statement with pics and complete details on how to identify the hubs that can be converted from free to sealed bearing.  Along with the best method and tools to use for removing the brass(?) bearing cup races in order to achieve a nice snug fit for press in sealed bearings.  Such that they use 3/8 inch axles. The only difference between the converted hubs and hubs that came off the line with sealed bearings is the style of axle.

I discovered this entirely by accident or chance while polishing some hubs just a few months ago.  Doable but time consuming and requires a lot of patience and power tool skills, lol!

Peace


HUTCH please, neat or on the rocks;  black'n'chrome or chrome'n'black, pure and unadulterated...like savoring a 20 year old single malt Scotch.  If I wanted a candy color flavor, I'd have ordered a glass of Haro.

I  think this bearing may work

16062RS  3/8x29/32x5/16 inch

The  OD is  23.02mm so if  hub is 24.50 then you can machined a sleeve 0.74mm thick

Its a 1606 bearing

https://www.nationalprecision.com/ball- … l_inch.php

Skyway  uses a 1614 and the  1606 actually rated  slightly  more for  load i so i think it would be ok.

Re: Converting my GT Mohawk hubs to sealed cartridge bearings

Sorry to bump an old thread, I’m just curious if El Gecko ever got his hubs dialed in.  I just picked up an old 2000 Dyno XR with triple wall ZAC-Xs laced to Mohawk hubs.  Rear axle is bent and/or cassette may be bad.  Figured I have to replace the axle and cassette so might as well see if this sealed bearing mod is doable.

Re: Converting my GT Mohawk hubs to sealed cartridge bearings

Not yet, but it's funny you brought this thread up again because I started working on them again recently.  Got my grail Pro Series last fall and now I'm gonna use these converted hubs (my originals from bitd) on that bike.  Need to figure out a better spacer system for inside the hub, or find a machined axle with shoulders that's the right width.  I was having trouble keeping everything tight with the hardware I got, and I actually cannibalized them awhile back for another project.  Never even got to lace em up and ride em.  I need them to be strong for this bike, so I'm gonna try to do it right this time.  Hopefully I'll have some updates for you guys soon big_smile

Phil used some kind of epoxy I think.  The only thing that sucks about 1st gen Phils is that there is no flange in the hub shell to keep the bearings in place, so if you get a really hard sideways hit, the whole axle and bearings can slide to one side and pop out.  Loctite works fine as a replacement.

Wow, seriously?    yikes

Guess that's why they are 1st gens, and not current gen.

Can't believe a hub manufacturer would not put bearing seats in the shell   roll

well it was literally the first attempt at a sealed bearing hub. they made them like that into the 90s. phils are junk yikes
