Timing belt replacement.

[bodkin1]

Wouldn't you know it, today the timing belt finally snapped on my truck. From the looks of it, this doesn't look like a fun job. I was curious as to if any fellow TRS members have a certain way to do the job.

Post #21 summed it up.

Also how do I go about removing the crankshaft pulley? It is virtually impossible to remove the 4 bolts holding it on with a ratchet and socket without it spinning either way. Will it harm the engine?

 

[bodkin1]

Well somehow managed to get the pulley bolts out (with help from a lot of penetrating oil), but it ain't going anywhere. Guess I will have to use a puller to remove it? Tried tapping it with a hammer, to no avail.

Advance has a nice rent-a-tool kit that has a pulley puller and installer. I ended up finding one on ebay and picked it up for about $35 shipped. Advance wants about $100.

Well I was able to finally get the pulley off, a few more taps with a hammer did it. Now what's really giving me trouble is what the pulley is bolted on to, held onto the camshaft sprocket by a 22 mm bolt. I am pretty much out of ideas on how to get the bolt out without the crankshaft going either way. Maybe an impact would get it outta there?

Impact will do it. It worked when I replaced my timing belt on my 2.5 liter

Am going to try that when I get home from work today. Got a 18 volt cordless impact I use at work that I will bring home. So far that's the only thing keeping me from going any further, the camshaft pulley.

As I recall, I used a ratchet with a long handle tucked under the frame rail, then bumped the starter with the ignition disabled.

 

[bodkin1]

By "bumping" it, you mean by cranking the starter a half second?

And I would put the ratchet/breaker bar on the right side (as I am looking at the engine from the front)?

 

[bodkin1]

Well finally got the 22mm bolt that holds the harmonic balancer off, by way of "bumping" the starter... the thing ain't coming off. Have tried hitting it with a hammer multiple times to no avail. Would a puller do the trick? Or hit it even harder with the hammer?

I applaude you for your efforts and give you a bump.....

I just drug my 2.3 to the auto shop in town where we get all our tractor parts from....

Finally had to borrow a puller from my dad's friend who runs a garage down the road from us. Had it off in 5 minutes. Reading some TB related theads here, gave in and bought a new Crankshaft Position Sensor ($148 from OReilly's). Had to take out the bracket for the A/C and power steering just to get the wire to the sensor located properly. That bolt for it underneath the engine is a royal bitch to get to: could only use an end wrench on it. Got the belt and new tensioner in place. Amazingly my dad and I got the truck timed on the first shot. Decided it was ok, and started putting everything back in place and took it on a test drive. She seems to run exactly as she did before. Ah glad to have my truck back running. Was only down for 4 days!

it is possible to replace the timing belt without
removing the crank pulley. crank the motor
while using a tire iron to fold the guard on the
crank out to give you room to get the belt in.
the guard looks like a big washer.
i broke a lot of timing belts before i figured out
that i had to hit the clutch before hitting hard
snowdrifts.
