I plan on cleaning my bearings using motor spray. However, what kind of oil do you guys use to oil them? I would imagine it's a light oil but if you can tell me the kind and brand and where to get it from, that would help a lot.
I just take the seals off, blast them completely with motor spray then put a drop or two of trinity royal oil and spin then for a few minutes so the oil get distributed evenly and they feel smooth. If they still feel rough I repeat the process untill there smooth.
I tried without taking off the shields for a while and finally did. I found old grease that hadn't come out in my lacquer thinner bath and motor spray cleaning procedure. The bearings were much more free afterward. So, I'd say that , yes, you have to take them apart occasionally.
to do my bearings i first remove the shields on both sides drop them into my egale bearing vibrator thingo with motor spray in it. then whip the bearings out oil them up heaps(5-6) drps then spin them a bit drop them back in and wait about ten min. pull them out let the motor spray evaporate the clean each sheild put 1 side on put 3 evenly spaced drops of orion free revs(it's what i use) spin it a little and put it all back to gether this way does take a little longer but i takes a hole lot more time between nesicary cleans and i've done six meets on a fairly dirty track and the car will still roll off a table tilted at like 5-8deg
