Whichever bearing is selected as a replacement, it is only as good as the Installer.
Why? - If you study the Installation Instructions for any LN product ,you soon realize how critical the Installer skill level is.It is not that their product is difficult.It is that LN really go to great lengths to ensure the installation is correct and successful.No detail is ignored. The lengthy Instructions are full of imperatives.
Other diy IMSB's may be just as critical but the Installation Instructions are often inadequate.
Probably a good idea to:
1. differentiate between diy and Pro (LN Approved)installed products.
2. find a local qualified installer & discuss.LN have a list.
The Pro Installer route may seem expensive until you understand how easy it is to screw up an IMSB replacement and how expensive the consequences of that mistake(s) are.
Yes, you can be successful with a DIY IMSB ,but it requires a meticulous standard of work that the average shade-tree-mechanic seldom rises to. For example freezing the parts and tools,buying the microencapsulated bolts, loosening the correct crankcase-half bolts, effective counter-stay and valve train locking,surgical cleanliness,correct tools for RMS install ....
Even the "smart guys" screw up :'the Pelican book instructions have at least one significant error'
We discussed this wiith Wayne and he did say they would correct this in their website. It is better, as Mike said to just read one set of Instructions and follow them to the letter. Linked for your convenience here:
