Question about 1988 Chevrolet Blazer
I have a 1988 s-10 Blazer 2.5. There is no timng chain, only 2 gears, cam and crankshaft. I need to know how to get the gear off the camshaft.
The gear is press fit onto the camshaft. The proper way to repair it is pull the camshaft and have the gear pressed off and a new one pressed on.
At one time I had made tools to do this job without removing the cam from the engine. I no longer have the tools, they were borrowed and not returned.
