Timing belt replacement on 2.4L going bad...

I borrowed a pulley puller (3 arm) from Autozone, and ended up breaking off a piece of my damper(on crankshaft) pulley flange. The pulley tool must have slipped and was biased to one side and broke off a piece of the casting (pulley is castt iron.) So now I'm in a bigger pile of dooo!

Which option to proceed on. As you may know, the pulley has 3 spoke and youtr typical puller will not work because it's designed for 4 sploke and has 2 working arms.

I don't know if there is another 3 arm puller that would do the trick. And I've seen somewhere where someone used a bearing splitter and put it behind the pulley and got it off that way. But I don't know how they pulled on the bearing splitter because of the 3 spoke pulley.

Use a sawsall and cut off the three spokes, then easy acces to pull the rest of the pulley?

Use a dremel to cut the hub and then use a chisel hammer to split the hub?

Get some dynamite and blow the thing to holy heaven?

Gey some beer and forgetaboutit?

I think you should be using this type of puller...

At least that's what I used on my 99, 2.5 4 cylinder

I used an autozone 3 arm puller and it worked for me...my only problem was the center of the puller messed up the thread for the bolt so I had to just use a thread tapper to clean it up. It did take two tries to get the marks on the cams to line up with the crank mark (put it all back together and had to take apart again cause it was one tooth off). I'm already not looking forward to the next belt change.

The puller they loaned me had 2 different length rods that go into the screw hole and pulley hole. The drive screw on the puller is hollow. The longest one was too short, so I put a smaller screw into the pulley hole and tried to crank on it with the puller screw. I think the puller was not on properly, as it's hard to hold everything in place and ratchet. The rods they supply ensure that everything stays centered, and also holds the puller in place as you engage the arms properly. If they had a longer rod, I probably would not be in this situation. Anyways hopefully somebody will read this and learn from it.

I've got a shop locally that will do the work (3 hrs labor) so I;m done for now, and hopefully no valves got smacked. If I need to pull the head I will be most dissabointed.

Got beer?

I just did one of these timing belts yesterday. Theres no holes in the pulley for that puller to grab. you need a special puller that goes into the deep hole where the crank bolt goes and bottoms out about 4 inches in.

BTW this is the same engine as the PTLoser uses so asking for a puller for a PT may get you the correct puller. This is the one I used.

Your 2.5 is a "shortened" 4.0. The OP has a 2.4 which is a different engine. You can read about both on allpar.com .

90k according to the pt book. Don't put it off as these are valve Benders and rarely make 100k w/o the belt stripping.

Same engine as the pt but with different external bolt on's.

I took my 04 2.4L to ~113K in 3 years and 4 days from new to totalled without a hickup. I ran M1 Clean 5000 10w30 with Mopar filter from the first oil chane to the last and never had one problem. I miss that TJ.

You asked a technical question in a technical forum, I answered it.

How is that following you around?

Its not my fault that you don't know the difference between the 2.5L engine and the 2.4L engine in a TJ (you don't have a timing belt)...
