I use a bearing puller made by JP racing. But there are several ways to do it. Heat the block up by the bearing with a heat gun, place it on a hot plate and heat it up, put it in a small frying pan and heat it up, put it in the grill or oven and heat it up. Just get the case hot enough and it should about fall out. May have to give it a little tap but it should come out pretty easy. The rear bearing may also come out. Just make sure you have some good gloves on and put the bearings in before the block cools off.

hold the crankcase and make sure the tip of the glow plug wrench makes contact with the front bearing from within the crankcase. Hold the crankcase and the wrench together and tap/whack/slam it on a wooden chopping board

Not if you have the tool. Kinda hard to get out otherwise. Could tap it out from the back side I suppose, but it's easier in/out with heat otherwise.

Here is a couple vids for using the heat method. He uses airplane engines, but it's all the same.

The GRP engine tool works like magic it is so easy its like cheating. If you have ever pounded a bearing out with a wooden stick and hammer you will appreciate this tool. Front bearings dont last forever and need to be replaced when they leak. I recently replaces the front bearing in an OS speed and after I gor the engine tore down it took less than 5 mins to pull the old bearing and insert the new bearing. I love that tool. I know its 180 bucks but its worth its weight in gold.

Do not Freeze your bearings because when you put them in and they cool down condensation will form and cause the bearing to rust.

+1 on that, never freeze your bearings. Heat the block, remove the old bearings, and drop in the new.

+1000 on this tool have done the heat it and beat it with a stick thing
if it is in your budget (save up for it ) get one the right tool makes it a
lot easier and you will not put off changing them a oven mite and a stick
are not the right tools
