How to remove and install cam bearings at home?
In order to remove and install cam bearings, you must have an install tool. You will be much better off purchasing a quality universal tool as opposed to a cheap bargain tool store unit. We got ours from Comp Cams. Note the box of bearings; we have them numbered 1-5 in order of placement in the block. 02.
What happens when you spin a cam bearing?
The damage is usually limited to the main journal surface on the crank and the main bore housing. A spun cam bearing will tear up the bearing bore in the block (or head in the case of an OHC cam), and possibly snap a timing belt or chain – which may result in one or more bent valves if it’s an interference engine.
What should I do if I have spun bearings in my engine?
If an engine has suffered a spun rod or main bearing, and the engine is rebuildable, it will require resurfacing the crank journal, possibly re-machining the main bore or big end rod bore (or replacing the rod) depending on the damage that has occurred.
When is the best time to replace cam bearings?
Once tightened, a hammer is used to knock the bearing out of the block. You want to remove all of the bearings before moving on, unless you are only replacing one. If you are at this point, there is no real reason not to replace them all. Now is the best time to thoroughly clean the block. 09.
