LOSTAR Bearing Pullers Editorial Review
The LOSTAR Mainshaft Bearing Inner Installer & Puller Tool 34902-84 is a mixed bag according to reviews. The inner race installer works very well, but the remover has quality issues with the centering cone.

However, the majority of customers found the product to be useful and performed its job as described.
