B7100 smooth fan belt - Bando FM 34.5

[AJT]

Hi

I have just snapped my Bando fan belt belt and have ordered a new one for a B7100 but it is too short and is toothed.

I have tried searching on Bando but get nothing back, so I imagine this belt is no longer made.

Does anyone have the part number for the smooth V belt (not the toothed belt I ordered!) or any compatible alternative as I can't find the correct one. 86.5cm long, 8mm wide.

Thanks

Try this Dayco one on Amazon.com for around $10. Size 4L380
The belt has very little stress on it. No water pump and only a low output dyno.

Amazon.ca

seems a 3L (3/8" wide ) belt is the proper width.
cogged (toothed) belts are supposed to be better...

Hi

The 7300 is the same length as the replacement I ordered. 77cm/29”. That fits on two pulleys but mine has 3.

My current belt is 86.5cm / 34”.

Odd.
Mine has 3 pulleys- crankshaft, dynamo, and tensioner.

Looks like you have a B7100 that someone has upgraded the engine in it.
Looks like a D850 or D950 with a water pump and a real alternator.
If you give me the number that is stamped into the block just to the side of the injection pump facing up i could be able to tell you the proper belts for it.

Or just take the broken belt to a local auto parts store and match it up.

And it doesn't mater if the belt is cogged or smooth, they both will work the same.

Thanks. I couldn’t see any number. I think my rather vague description of three pulleys was actually 2 pulleys and a tension pulley!

Ok. Finally took the plunge and order a 3l340 drive belt. Was 34” / 86.4cm. In all honesty it could have been a tad longer without issue. Thanks for your help.
