Need suggestions on how to remove fore and aft bearings from shaft on Dremel 370-5 Moto-Tool. I don't have a bearing puller. The bearings seem to be very tight on the shaft. My concern is the pot metal ''cage'' that surronds the forward bearing. I'm concerned that aggressive tapping on the shaft might break the surronding metal.

I have exactly the same unit a 395. The kit comes w/ a wrench to unscrew the nut holding whatever you have locked in. If you can't find the wrench then I suggest you get an adjustable wrench and lock it into the flat side of the nut. There is a place where it will lock in so that you can tighten or loosen the nut. Some of the 395's come as a kit w/ all the different attachments, accessories, heads and tools. If it came with a plastic case the wrench is usually slotted running parallel just in front of the handle. You will see it when you open the case and take a top view look at the handle. It is sometime hard to see but it's just there. Good luck.

From looking at manual there is no transmission or connector so the only possible explanation is that the shaft is broken. You might try calling this number
1-800-437-3635 to see if they repair or can further advise you.

Lubrication
ARM BEARINGS
Lubricate the arm bearings with oil after 10 hours of use.
Re-oil after every 50 hours of use or whenever there is a
squeak coming from the bearings.
TO LUBRICATE
1. Turn saw on its side (Fig. 18).
2. Remove rubber plug to expose bronze bearing.
3. Squirt a generous amount of SAE 20 oil around the shaft
end and bronze bearing.
4. Let the oil soak in overnight in this condition.
5. Next day repeat the above procedure for the opposite
side of the saw.
