T104 = Trapezoidal tooth belt in HCR rubber, 24,000 miles/ 24 monthsI see the Gates T249 belt gets referenced quite a lot. Something to bear in mind is that this is not just a Gates T188 belt made using HSN rubber, the tooth profile is different too.
T188 = HTD round-tooth belt in HCR rubber, 36,500 miles/ 36 months
T249 = HTD round-tooth belt in HSN rubber, 50,000 miles
T188 & T249 are fit interchangeable, but the T249 is the more durable belt.
T188 doesn't work in the UK, but asking for Gates part number 5168NS does.
