Restoring crank and rod bearings
In the past I recollect restorers using two kinds of powder (one course and the other finer for finishing) which when mixed with oil were used to restore bearing journals. Prussian Blue was used to measure progress. One of the powders was color yellow. Apparently the abrasive qualities deteriorated to zero with use so that clean-up was not a big concern.The reports were very positive. I am unable to find info in the archives. Does anybody have further info, advice, including source for obtaining?
Thank you in advance. George |

Re: Restoring crank and rod bearings
Timesaver for babbitt and soft metals like bronze or brass comes in three grades of abrasiveness. Follow the directions regarding the relative amounts of Timesaver and oil in the mixture and do not exceed the percentage of Timesaver advised. You should only need the fine grade although a rough fit might require the medium grade. Take your time and do it right!

Edit: Friend says I am too negative. I do like timesaver, just watch the crank end play. Should not be a problem unless you do a lot of lapping with coarse or medium grade, but again, pay attention to end play. Last edited by PC/SR; 04-25-2019 at 12:19 AM. |
