Hi All,
Please can you assist. THe Shimano speedmaster driveshaft with the screw that fastens it instead of the circlip as in the attached picture, does it require some loctite threadlocker to keep it in place?
Many thanks for the advice,
Cheers,
Leon
honestly, i would still use grease. just bear down on in until it is good and tight. it should hold just fine. just be aware in case it loosens.
Thanks Alan,
I will make sure to crank it properly, with loctite it does seem like it is a disaster waiting to happen especially being 2 different kinds of metal
the problem is using loctite on previously dry threads will not prevent corrosion.
Alan: I had a problem with a loose screw on a handle replacement (Sal no comments about a screw loose :D). I had to put Loctite on it to keep in place. I was wondering if gasket sealer would accomplish the same thing as greasing (water intrusion protection), yet gasket sealer does not totally harden but dries like a soft glue. Also the screw can be turned out when it is needed to be loosened. I expect that gasket sealer would protect from both water intrusion and loosening from vibration, especially on internal parts where one cannot monitor the tightness. Gasket sealer will also protect the parts from corrosion. Dominick
if you are having a problem with things loosening up, go for the loctite. if you are not having a problem, i would rather see you stick with grease. too many times i've been stuck trying to back out a corroded screw and wished that the guy before me had dabbed on just a little bit of grease.
you might like to try a bit of mono fishing line.i only use loctite where i must.cheers

Dominick, no comment about your screw being loose, you already know that ;D. Use loctite only if you must! I have some housings that can't do much with them, someone really liked to use loctite on those screws. Sometimes things don't work out the way you want them to, you can try heat and everything else to remove the screw and you'll still ruin the part. Cast aluminum parts will give before the stainless steel screws will.
Hallo
Busy servicing Shimano Speedmaster IV (Drive shaft moves from side to side) The image/attachment in this post does not open for some or other reason, is the photo still available somewhere, alternatively what does this screw look like that is depicted in the post. Can a second circlip be used if there is too much play on the shaft?
