PeteB1966 Posted September 1, 2018 Share Posted September 1, 2018 (edited) Hi guys, new member here, I have a 78 750 fitted with a Metmachex arm. I need to replace the bearings and wondering if my arm takes the same bearings as a standard arm. Just wondering what I need to order before I take it apart. Thanks Edited September 1, 2018 by PeteB1966 Quote Link to comment
gs7_11 Posted September 1, 2018 Share Posted September 1, 2018 Are you sure that's Metmachex? Looks more like a JMC to me. I'd be interested in the answer to your question.....I've got one too. I'd assumed it used standard bearings. Quote Link to comment

PeteB1966 Posted September 2, 2018 Author Share Posted September 2, 2018 Yep tis definatley Metmachex, I removed the sticker when I first got it. I'm going to remove it today and see whats there, keep ya posted Quote Link to comment
CockneyRick Posted September 2, 2018 Share Posted September 2, 2018 Too skinny to be JMC & the adjusters Quote Link to comment
gs7_11 Posted September 2, 2018 Share Posted September 2, 2018 Yeah, I just hadn't seen that kind of bracing on a Metmachex before. Good luck with the bearing job. I've just taken some out if a standard GS1000 arm and they were a right bugger. Quote Link to comment
PeteB1966 Posted September 2, 2018 Author Share Posted September 2, 2018 Got the arm out, bearing size is 33 o/s 29 i/s 30 d so not standard size? Guessing I measure inside between the rollers right? Or is it casing size? Standard size is 22x29x30 Quote Link to comment
CockneyRick Posted September 2, 2018 Share Posted September 2, 2018 No bearings remotely that size! Double check your OD measurement & see if any numbers stamped on it Quote Link to comment
PeteB1966 Posted September 2, 2018 Author Share Posted September 2, 2018 Youre right my bad, just checked again... 33 o/s 23 i/s 30 d Quote Link to comment
gs7_11 Posted September 2, 2018 Share Posted September 2, 2018 I've got some standard GS1000 ones here. They areTA2530Z, which is: 33 od 25 id 30 deep. Could it be those? Measure the id to just inside the outer race. https://simplybearings.co.uk/shop/advanced_search_result.php?search_in_description=1&keywords=ta2530z Quote Link to comment
PeteB1966 Posted September 2, 2018 Author Share Posted September 2, 2018 Ah thanks bud, thats probably where Ive gone wrong then as I measured the i/d across the face of the rollers ( not that they roll any more as rusted up solid) the arm is stamped gs750 gs1000 gsx750. Thanks for the offer but am popping into my local shop tomorrow they keep a selection of bearings in stock. Quote Link to comment
