Question about installing Shimano Cassette
Hello All,
I recently took off my Shimano Cassette (HG 50 8 spd) to clean it and noticed on the lock ring that the I should tighten with 40 Nm (Newtons I presume) of pressure. I don't own a torque wrench and was wondering just how tight the ring needs to be and what exactly 40 Mn amounts in terms of the Park chain whip tool (SR1 I think) I was using might equal. Seems to be working ok, but not sure if I might have tightened it too much and am creating a problem because of it. Thanks in advance. |

If you have no possibility of measuring the torque applied, think then in terms of the torque required to properly tighten a car wheelnut for alloy wheels (approx 110 Nm), then take somewhere between a third and half of that for the lockring. Sorry, can't explain better than that . . . The torque value is probably not so critical. Just avoid being too tight (damaging the lockring and freehub threads) or too loose (shifting not working quite right because of too large a distance between cogs and spacers if they're not properly squashed together).

Question about installing Shimano Cassette
40 N*m is about 30 ft*lb. You don't need a torque wrench, just tighten it with a fair amount of force on a 1 foot wrench. I use a die stock to hold the splined tool as its a perfect fit and the setscrews retain the splined tool. A die stock has two handles which allows one to maintain pure torque. Since each handle is about 6" long, I put about 10 pounds of force on each. -- Weisse Luft |

You don't need that to install the casette. |

We can give him the benefit of the doubt here I'm sure. He did not actually say that he was going to install the ring with the whip. His words were "was using". I chose to interpret his text as asking for a *comparison* between the force required to tighten the lockring, and that required to remove it (with the whip and spline wrench, as he must have done). In fact, none of us (including myself) ever answered this question of his. But if he really was using the whip to install, I guess he's got the message by now ;-) To OP: Rhesus, you still messing with that cassette? /Robert |

In defense of the OP, the Park chain whip tool has a socket on the butt end to hold the splined lockring tool: http://www.parktool.com/tools/SR_1.shtml |

Question about installing Shimano Cassette
You're correct, its that the opposite end of the Park Chain Whip is also a
wrench that fits the FR-5 cassette lock ring tool, sorry for the awkward wording. I mentioned the tool because I thought it would give some people who respond an idea of the size of tool I was using. The link below shows the tool. http://www.parktool.com/tools/SR_1.shtml "Richard Tack" wrote in message ...

Question about installing Shimano Cassette
the SR-1 has a wrench on the opposite end of the whip that fits the locking
ring tool - mentioned it that way because I was trying to give an idea of the size of the tool I was using.

Sorry for the confusion. I just use the cassette tool and fingers, no need for chain whips or wrenches. It has never worked loose, although I do tend to take the cassette off to clean every few months. However people do say the nine speeds are more temperamental. |
