Bamboo GT Street Belt

I would like to know if these belts are the right spec for the GT street setup
D&D PowerDrive 250-5M-15 Timing Belt

 

Old street belts and Gt street belts are not the same length.

 

Old belts are 260-5M-15, don't know about new...

 

I have swapped out belts on gt street setup is 245 5m 15 a/t is 360 5m 15

 

first number ie 245 is length in mm the second number 5m is tooth pitch and the third number 15 is the width in mm

 

When I got my street kit they accidentally put in the old street belts. I had to wait for the GT belts because the old ones were too big.

 

Gt -0004 52 teeth (?)
Gt3 - 50 teeth.

Not much in it! but it must have meant it was too big to use or I would have used.

 

Are there not different sized gears available for the GT? I only have a Gen2 but I have 97's on it with some type of GT gear that I got from OZ...

 

245 i5m 15 s for 38 tooth right? I was under the impression that 250 5m 15 would be for 32 tooth

 

Gt004 if for 38t

 

2 teeth = about 5 mm so 250 is for 38t, 245 for 32t
Apparently they are GT3 belts not hdt, but the weaker hdt work fine I have found.

 

I picked up the 250 belts thinking it was for my 32T. Just got the 245 to be safe...thanks for the info. According to Alli express the 250 has 1 more tooth than the 245 so will count to be certain.

 

The stock evolve 32t GT003 belt has 50 teeth....just counted like 3 times. The 250 has 50 teeth and the 245 has 49 teeth. What am I missing here? I dont have a stock evolve 38t GT004 belt but curious as to the amount of teeth on that?

 

yea man no idea. There are MANY threads on reddit saying 250 for 32t but didnt seem like anyone tried it. Maybe they both work but 1 is not ideal
