Can you tell me where I can get new drive chains from. My DD has narrow chain links that don't seem to be available. The rollers are only 3/4" wide whereas standard chain is 1" wide. |

I ordered new chain a few years ago from a bulk chain supplier. I gave them the information on the chain from my parts book and they had similar chain in stock and I the new chain within a week. ------------- Jack of all trades, master of none |

I am not sure but I think that chain was identified by a number, #60, #80, etc. plus pinch and number of links. I don't remember the number but it was listed in the parts book. ------------- Jack of all trades, master of none |

Looks like page 128 1 1/4 or 1 1/2 pitch #100 or #120 ------------- Faith isn't a jump in the dark. It is a walk in the light. Faith is not guessing; it is knowing something. "Challenges are what make life interesting; overcoming them is what makes life meaningful." |

I checked the number stamped on the side of the chain link, it is 121. It has an 1 1/2" pitch, but the roller is only 3/4" wide, which is not a common size. I think my only hope will be to try find NOS chain unless anyone has any other suggestions. Standard 120 chain has 1 1/2" pitch but a 1" wide roller. This size chain is too wide for the double sprocket. |

Sounds like the deal with bicycle chain where pitch is #40 but chain is #41 that is thinner in width . Ran into that on both bicycles and overhead garage door openers that used chain. Use to find a lot of things like that at old military surplus places that handled vehicle parts or surplus military hardware - know for a steer axle CV joint for my Pettybone loader I found one at a place like that over in Mpls - but most of those places are gone now over there as City is beautifying areas and putting up appt buildings and condos for yuppies http://www.fbchain.com/roller-chain-size" rel="nofollow - http://www.fbchain.com/roller-chain-size http://www.fbchain.com/roller-chain-size/roller-chain-dimensions-35-ansi-b-29-1" rel="nofollow - http://www.fbchain.com/roller-chain-size/roller-chain-dimensions-35-ansi-b-29-1 ------------- Faith isn't a jump in the dark.

Found this on google: https://octaforce.com/diamond-american-standard-roller-chain-d-121-60-3-34-pitch-19-05mm/" rel="nofollow - https://octaforce.com/diamond-american-standard-roller-chain-d-121-60-3-34-pitch-19-05mm/ You might find it in the oilfield industry, saw 121-2 and 121-3 (double and triple) listed fer that...
