If oil seals and flanges are fitted then the additional torque to turn the shafts will be significant.

The flanges haven't been fittet yet, the oil seals are in. All the bearings got oiled. I measured it again for a couple of times and got something between 3.5 and 4kg with the China scale, which is within specs of that old manual, albeit being on the upper end.

It sounds as though you don't have much to worry about, I wouldn't be too concerned.

May I ask a related question: I have assembled the input shaft too and this time I feel the preload was waaaay to low. With the scale it only required 0.2kg of force to turn it (without intermediate gears). I initially set it using Nigels method with shims between the case. After disassembling and cleaning it I measured again: 0.03mm. So I'm doubting the dial / arm I'm using. Might be too unstable and giving me a too high margin of error.
That's why I went with the scale method next, again referencing the old manual that specifies between 2.26 to 9kg preload for the input shaft (a rather large margin). After adding shims and measuring again and again I'm currently at around 3.9kg force required to turn the input shaft (string wraped around the cross drilled part of the shaft). To me that feels rather tight, but then again I have no experience with the LT 230. |
