OS FS-60 Bearing Installation

[@ronitsingh85]

I was eagerly waiting for the progress of the FS 60.

[@ronitsingh85]

I don't know how much heat is generated inside the crankcase but am sure over time the heat will dry out the grease or oil inside the shielded bearings. Even if this does not happen, the oil that comes out of the fuel would be liberally lubricating the bearings thats open to prolong its life. There are also ceramic bearings with quite a long service life, maybe a nice upgrade for an engine that is run a lot. The OS fs 60 is coming along nicely!

Good man

And I'm sometimes moaning when - rarely- any of my Laser engines needs new bearings - they have 3 in them. The big Saito FA-220 has 2 of them. This thing has 5 of them!!! I should never moan again :) Regards Harry

Bearing installation is definitely not one of my favorite parts of a rebuild for sure.

[@Laser100man]

@@dmrcflyr2 Most definitely I don't blame you David.

Even replacing bearings in an electric motor is not my idea of fun either.

Nice, this came sooner than expected. Regarding the replacement bearings, I know you had a trick to find them at Boca (by using FS90 lookup). But Brant's eBay site has nothing at all listing FS-60. Was there a similar trick to finding the correct bearings at his site? Thanks!

[@dmrcflyr2]

Yes. I used the actual part numbers of the bearings like: (1) MR6001-ZZ (1) R6 I contacted him via the eBay contact feature and simply asked for these bearings. This is why it is important to have the bearings required on hand and not simply go by the name of the engine.

you pop bearings out, and if they dont have numbers, measure them. theyre all standard, and being japanese, metric. easily obtained... if you can, abec5, be ready to pop a seal out in some cases... very few bearings are "custom".

[@chuckmcdonald4795]

Is there a hood method for this without using an Arbor press. Hate to spend the money for something i might use a time or 2 a year or 2. Lol

[@dmrcflyr2]

@@chuckmcdonald4795 Yes it is possible to install bearings without a press, but it is much more consistent and safer to use a press. I cannot tell you a better method than a press however. I suppose using a vice as a holder and sockets or something similar as the awl and then use a mallet out light hammer to tap them in. Personally I’ll use my inexpensive press especially doing customer engines.

cases in hot oil or just pop them in the oven at 150. shafts in the freezer, maybe in alcohol... the bearings in almost all cases just fall in place.
