down from alaska at the inlaws for christmas in oregon, sister in law came to visit as well and her KDP ejected from the engine (1998 12V)

engine still runs but the timing case is broken and has a chunk broke off thats rotating around a bolt, also exxon valdeeze

from what ive read i need gaskets seals and timing case. take out rads, remove accesorys.

then cam gear gets pulled or camshaft removed (dowel trick for the tappets, etc) which method is fastest/reliable?

then case can come off, new gaskets and new case, assembly is reverse of disassembly, locktite on all bolts, new KDP to align case and if NOS case KDP tab

did i miss anything? any tips tricks?

thanks in advance

Can it be done in 2 days yes but wether or not you yourself can do it in 2 days depends on your own ability. You will be removing the injection pump too. It also depends if your doing this in a well equipped shop or in the front driveway. Removing the cam gear from the camshaft is not an easy task or likley option without the proper tools to do it.

Got a floored barn/shop, all basic hand tools (sockets wrenches screwdrivers pliers) will a part shop rental 3 finger puller work for the cam gear or does it have to be specific tool?
do you have to pull the pump or just the gear on it so you can swap the timing cases?

I wouldn't want to try it in 2 days, can you patch the case for a short term fix?

This is my personal story, been running a patch for 8 years now.

If you get the cam gear off with a puller how are you going to get it back on? Personally I would not recomend you doing your first one without some experience in doing something similar. It's more like transmision work getting that gear back on the cam without damaging something. It needs to be heated up in a bath of oil to reinstall, or that's the only way I have done them myself, but you will not likely get it back on without a heat source and no a torch is not something to consider.

Right now is the perfect time to replace the tappet cover gasket. They are prone to leak with age as they get brittle with all the heat cycles they see. It should last another 20 years when done.

We use differential heating occasionally on certain parts of the helicopters I work on, torch is right out for reinstall I agree, it needs to bake at 300f for an hour and cool the camshaft. Ive had another person mention the tappet gasket so I'll have to see if I can find one by Saturday

The tappet cover gasket is easy to find - got mine at the chain auto parts store. Felpro brand, which is perfectly good. Do that while you have the injection pump out - its not fun, but that's the time to do it.

It could be done in two days if:

I had every tool needed

Enclosed garage or no weather expected

All parts on hand including new timing case, oil, coolant, ect.

Make sure you also get a replacement dowel pin. It is needed to keep the housing indexed to the block, so the gears will mesh properly.

I have done a few, and learned to leave the injection pump in place. I just remove the gear from it. I have always removed the camshaft, have never tried removing the gear but it's sure tempting for the hours it would save.

A nice tool to build would be a fixture that bolts to the block in place of the lift pump, and holds the camshaft in place while the gear is reinstalled. I've never looked to see if it's possible or feasible, but maybe someone on here will run with it.

Good luck with whatever you decide.

You can remove the cam and leave the gear on it. If you were change the cam you can heat the gear in the oven. Put a little oil on the cam snub and move fast it will fall in place if you got it warm enough!
I agree with torquefan, good luck and make sure to have someone take Murphy to the bar way away from you

No turning back now, $10 of bolts made a chicken foot puller fit to pull the cam gear, it came off fairly easy, ppump gear popped right off easy peasy
