I looked through PRB and Russell which showed no Lasonic listing. I searched here and found no definitive belt sizes for TRC-918, 920 or 931 2nd Edition. I do need belt sizes for these 3 models if anyone has them, I would appreciate the info, thanks!

PRB Unfortunatly don't have Lasonic belt sizes. Your best bet is to measure old belts end to end, multiply by 2 then subtract 5-10% for stretch. Unfortunatly I've replaced belts on all those Lasonics but forgot sizes. The 918 is the hardest to replace belts on and if your not familiar with it, it can be very intimidating. The 931 is easy to get into deck but you need 4 hands to get belts on (there are 3). The 920 is pretty simple. Good luck :thumbsup:

The main drive belt on the lower deck of early 2nd edition 931 ---- SBS7.0

That is the size I picked, as mine was 7.75" stretched and the 7" is working just fine. :thumbsup:

The main drive belt on the deck of TRC-918 ---- SBS9.2

That is the size I picked, as mine was 9.75" broken and the 9.2" is working just fine.

One thing you need to be cautious with is if belt is to tight it can damage motor and capstan. I always order extra size belts in between in case this happens. I eventually use any extras on other decks :-)

I also need to replace my 920 belt I'm wondering if the 918 uses the same belt size as 920

I know it has been asked before, but does anyone have the belt sizes for Lasonic TRC 920?

 

Does anyone have belt sizes for Lasonic TRC 975?

On my TRC 931 2nd Ed. top deck was SBS16, bottom deck was SBS5.1 and SBS4.6 (didn't do counter belt).
