Default Replacing Engine Bearings

im replacing the bearings in my engine right now and got the front one in but i guess it wasnt hot enough to get the rear one in so will it hurt the front bearing to heat up towards the rear so i can get the rear in?
thanks for advice!

As a ground rule yes, any heat build up more then the operating temp will hurt my advise is you use a heat gun and the bearing extractor or installer to assit the in the job without causing damage.

Or you can just get a new set and do a new install, I had a bad install once and took the chance of reheating to extract and reinstall properly , the engine leaked and got damaged.

I change rear bearings all the time with the front installed. The front will be just fine. Dont sweat it. Just reheat and use the crank to help pull the rear bearing into place and make sure the front is seated well after rear install. Just take your time and make sure to get the block nice and warm. These motors aren't rocket science. If you were good enough to get em out, you can put them back in just fine.
