Appologize in advance if this is stupid but I need some help with 2 problems and no to little money and not enough time is not my problem its my reality. 1 I can not get the timing chain prockets to move. I have sprayed PB blaster on and aroud the sprockets and shafts but still no movement. Crank is still in the block with just the main and rear caps still in place. Any solutions or toughts? 2. How do you remove the oil filter cap on the block? I have removed the cented bolt that the filter screws onto. Solutions or thoughts? Thanks Bing

For the timing sprockets, get two big flat screw drivers and carefuly lever them off. Once the crank sprocket has moved far enough, a gear puller can be worked around it. Just be carefull not to damage the sprocket with the puller. You can also get a hammer and one of the screwdrivers and carefuly tap it off. Sounds like you have a spin on filter. Getting the center nut off is usually the hard part. The sheet metal part is probably glued to the block after years of use. Try heating it with a heat gun or steel a blow dryer. And again use a screw driver to carefully pry it off. If you do mess it up, it's not a big deal. They can be straightened and new ones are easy to acquire.

Charlie, I got the oil cap off thanks for the help. I still can not get the crank sprocket to move. The cam sprocket moves with ease. I tried rubber mallets, screw drives and no luck. I will try a gear puller and see if that helps. Is there a way to unhook the timing chain? I looked last night but did not see any. This would atleast allow me to get the motor completly tore down and allow for more room to work on the crank sprocket. Thanks Bing

If you take the core plug out at the back of the block, you can push the cam back to get the gear off and remove the chain. Try heating the gear and then prying. You'll need a big screw driver. A small one will just bend. You'll probably be replacing the chain. In that case, you can cut it off as well.

Bing: What Charlie said is true, but do it with the engine upside down so that the lifters fall clear of the block when tapping the cam out of the sprocket. You can actually tap the cam backwards to knock the expansion plug out. Then you will be able to take the crank out, and have better access for pulling the crank gear. John

Hi, you could also try 2 large chisels, one either side of crank sprocket and tap them in one at a time just to get sprocket free and koving then should be able to be moved with screwdriver or tire irons.

I have had some luck using a drum brake adjuster tool to help lever off both sprockets from the backside. Gentle force, usually tapping it with a rubber mallet. It has a sharp bend that helps. If the timing chain is a throwaway I usually cut them off to get out of the way. And as has been said heating the sprockets helps too.

Thanks to all for the suggestions that were offered but Charlie gets an extra pat on the back today. I pushed the core plug out about 1/2" and the timing sprocket cam right off. Block is completely dissasembled and ready for sonic testing this week. Thanks again.
