Does anyone have any suggestions on how to remove the timing gear from the camshaft on my 88 4 cylinder??? The engine is still in the car with the cradle swung down.

Can I ask why it needs to be removed?

Only because you are looking at a big job if you cannot get a puller on the gear. The gear and shaft are held in alignment by a woodruff key and press fit to the shaft.

As long as you can get the timing cover off, having access to the oil pan front bolts/screws and can cut the oil pan gasket if it is stuck to the cover. I don't see why you would not be able to change gears with the engine in the cradle......

Replace Crank seal.

Would you like the page out of the chiltons' manual?? it calls for a cam shaft removal... lifters, push rods,.....etc

Well, you can remove it with a gear puller (of sorts), but then you have to put it back on. This is the difficult part. You can't pound on the new one as the camshaft can move. You will have to hold the cam shaft in place. You can pull the lifters and then pull the cam shaft out... Either way, a lot of work, sorry.

This is Back On Holiday's write-up that I used to fix mine. The hard part is getting the new gear back on. I had trouble finding the proper size tap (with matching bolt). Also, you need a good quality drill and bit to drill the center hole in the cam. If all else fails (and you have the engine out in a public parking lot on Memorial Day, 500 miles from home) you can heat the center part of the gear and beat it on with a hammer. Totally piss poor way to do it though. You have to keep pulling the gear away from the block, heat it, whack it, repeat. Not recommended.

OK second try at a write up. I hate it when you typo the username or password and lose thwhole $&$&^%$&^#@ ing post.

With stock fibre gears, this is really easy. Steel gears, you're on your own. The guy that told me this trick also told me to throw the new gear into some oil to soak before I started the rest of the job. I don't know if it does anything but the rest of what he showed me made me tons of money. I allways used heat to burn the seallant off the timing cover for fast removal. Drill a single hole in the steel ring of the cam gear. 3/16 or so. Drive a tapered punch into the hole and crack the cam gear. It now slides off easily. if required drill and thread the end of the cam. Use a threaded rod and a nut and a bearing, i used an AC compressor wheel bearing, to press the new gears on.

Paid over 12 hrs at the dealer, took 45 mins or so start to finish usually.

Rick
