Gustavo, the part numbers for my LT40 are different from yours, so I can't help you directly. Try this ...

Find the up-down chain in your manual. See if it has a description that looks something like "chain, #50-2 ...". This will tell you the size of the sprockets.
  #40 = 1/2" pitch.
  #50 = 5/8" pitch.
  #60 = 3/4" pitch.
and ...
   #50-2 means 5/8" pitch with 2 strands.

If you have this information, all you have left to do is to count the teeth on the sprocket.

We buy them from 2 different companys but under the same part number. Here is the manufacturer number. DS40B10x3/4. Maybe someone down there can cross them over.   Thanks

If all else fails,  you could take the old one to the parts supply place and see if they can match it.

If you're talking 4 pinions/sprockets you must meen the offset idlers.  They should be a common machinery supply item if you have a local supplier.  The chain is a # 40 and you can count the teeth on the sprocket and measure the center hole to describe it to the machinery supplier possibly over the phone.

As previously described, if you can take the defective part to the supplier, maybe he can either match it or supply one that can be adapted.

If you need the drive sprocket mounted on the gearbox output shaft, it's a 2-chain, 11 tooth, one inch bore sprocket unless you have the integral shaft and sprocket assembly.  If you have the assembly, you might still be able to machine off the defective sprocket and fit  a one-inch bore replacement onto the shaft.

Good luck

Just looked at the manual and see that you are referring to the "drive" sprocket.  My industrial supply catalog (Grainger) doesn't list a #40 chain 11 tooth sprocket as a standard with a one inch bore.  No real problem. A machine shop can bore a standard socket out and re-broach the keyway.  If you have the integral shaft and sprocket assembly and choose to replace locally, you'll have to machine off the old sprocket and mill a keyway for the replacement sprocket.

Hope this hasn't gotten too complicated.

Again, good luck.
