Magnum 4 stroke repair
Can anyone put me intouch with someone who can repair or has replacement bearings for a 1.20 Magnum four stroke engine. The bearings may be shot in my 1.20 and it might need repair. Thanks for your help.

If I buy replacements, how hard is it to get the old ones out and replace them with the new ones. I've never gotten this deep into tear down of a 4 stroke. I've had them completely apart except for removal of the bearings.

Put the crankcase in your oven at 200 degrees F and heat for about 15 to 20 mins and the the bearings will tap out very easily. Reheat crankcase when putting the new ones in.

You must heat the crankcase. They are a press fit. Hobby People are the distributors of Magnum and they will repair it.
