Camshaft Sprocket Removal

Hey Angella, I know it's been a couple months since you were asking about the Camshaft Sprocket tool that is used to remove the camshaft. You had said something about a website that explained how to remove it without the need of the tool. If you're still on this website I'd love to find out that website. I've searched and can't find anything. I too need to remove the Camshaft sprockets and don't want to spend a ton of money on something I'll barely use. Anyone else with ideas would be greatly appreciated.

I don't remember the site... but we ended up putting a socket on the bolt/screw heads you can see through the sprockets. Worked great... just keep it a smaller sized socket (1/4 or 3/8). It'll look like it's giving a little... but messing with those bolt heads a little isn't going to hurt anything in the long run (it's not a moving component, it holds on that big old metal dirt shield important, but won't really affect it one way or the other...

Glad to hear everything went well!

How did you fit the 3 row radiator? Did you do the electric fan mod and free up some hp at the same time?

And what of firestone? You probably should have driven it by just to rub it in.

Thanks

Thanks Angella,

That sounds so logical it's almost funny. I haven't had a chance to try it, but I can see how that would work. I know the bolts you're talking about so shouldn't be a problem. I've got my engine sitting on an engine stand with new one on the way (see picture).

One other question for you pro engine guys. I'm planning on swapping out the following for new. Anything else I should think of replacing while I'm doing this:

Water Pump
Thermostat
Idler Pulley's
spark plugs
timing belt
fuel injectors

Someone suggested replacing the Cam Oil Seals because they dry out easily. Is there anthing I need to remember when doing this. I've taken these out on my junk engine, but when replacing on new engine (see picture) do I need to be careful or do anything special?

Any help for a novice would be GREATLY appreciated!!

I am definately NOT a pro, but you don't need to replace fuel injectors. If you are worried about them, have them pulled and cleaned and before and after flow tested. I did that to mine when I reshimed my valve train and despite 256,000 miles of driving they were either dead on spec or only 2% away from spec.

I used cruzin performance's services and they did a GREAT job.

Here are the flow test results before and after

I will definitely check into that. When I pulled out my fuel injectors (and I am definitely not a pro) This is a first time for me. This is a second car that I'm fixing just to have a second car and to see if I can do it. Anyway, when I pulled out a few of the injectors it looked as though the end's had a plastic looking piece that had cracked off. I just assumed they were shot and needed replacing.

Mine had that too - and they replace all o rings and sealers, and those end pieces. When I got my injectors back I did not recognize them they were so clean and shiny. They could have been passed off to a toyota dealer as new and not 15yrs old!

I strap wrench didn't work for me. It wouldn't hold the cam gear securely enough. I tried using a long socket on the backing bolt and eventually got that to work. If you use a short bolt, the socket will slip off it. If you use a long bolt, it will bend. Finally, I figured out I could use a long bolt, put several nuts on it to reinforce it, and put a long socket over that.

It took a breaker bar three feet long to break the cam gear bolt loose on mine.

A 3 foot breaker bar!!!

I've got the universal sprocket holder tool and it's not nearly long enough to hold against a bar that big, thats too much leverage for one man to conquer alone.. Are these reverse thread, or do I just need some more muscle against it... Maybe a little penetrating oil. Any tips would be usefull.

Also, what happened with that three row radiator? I sent mine to a shop and they said it was junk. I'm going to replace it, and would like to go with an economical electric fan solution as well..

thanks in advance

1990 included?

The 1990 6cyl that I had a look at today is right beside a Toyota dealer and the campaign for the head gasket was never on this vehicle - If I buy it and it goes I have to pay for fixing it myself. It was never done there either (past)

Not all are covered.
