Issues with installing the backrest wheel
Thread Content
When installing the backrest wheel heater, can oil be applied to the shaft diameter?
It should be possible; otherwise, it will be hard to get out in the future.
Sure, just apply a little butter!
Why do some craftsmen say that touching the oil can cause oil absorption, making it harder for it to come off later?
When installing it today, I touched it a bit; an experienced worker said that one shouldn’t touch the oil on it, as doing so makes it harder for it to come off. I don’t understand why
Yes, some manufacturers produce backrest wheels with a large degree of interference between them and the shaft; even after heating for assembly, this interference remains, so a small amount of lubricant can be used during installation
Lubricant or grease can be applied.
Sure! But it’s best to calculate the expansion amount after heating! ! ! Before installation, use measuring tools to check the fit clearance to ensure successful assembly! ! !
