Hi i have a 1985 22r pickup. I am in the middle of rebuilding my head and i broke my timing chain guides in the process. They should be replace anyways since they are still stock. I hooked up the bare head so i can still bump the starter. I have read on all the other threads to use a 1/2 breaker bar and bump the starter, use chain wrench, 1/2 impact gun, and i even made the holding fixture with the 3 holes and the 30 inch bar welded on. Broke a few 19 mm sockets already and wasted to many days working on one bolt. It has been heated through out the entire process have used pb blaster penatrater, wax, wd-40 and a few other penatraters

I read in another post about cutting the washer type flange off would relieve the tension behind the bolt would cutting that off really release the tension and will the bolt come out with ease.
Any help is great And should the toyota dealer stock this bolt

Have heard that if you cut a slit or two in the flange of that bolt, that will help release the clamping force tension on it and make it easier to remove. Also, make sure and use a 6-point impact socket on that nut, not a 12-point one or a regular hand socket. And yes, any Toyota parts dealer should have a replacement bolt.

ok so i shouldnt have to cut the whole thing off just a few slits. then impact it off after i heat it up again

A good 6pt impact socket will not break on you. Get a long pipe to slide over your breaker bar. The longer the pipe, the more your force is multiplied in the bolt. I find 48" works quite well. It's entirely possibe the pulley has rusted a little making it a pita to take off.

take a large punchand put it in the centre of the head of the bolt.
Hit it several times with large hammer, then try the impact wrench again....

I have had to cut two off. I cut the whole head off, slid the pulley off and the rest of the bolt came out with ease.

Thanks a lot crawler poowell and rob. those links confirmed that my last resort was to cut the washer off. it twisted right out with my fingers after it was cut up

Now i can finish up this project

This is why it is always a good reason to pull the oil pan if you are doing any major work on your truck. I guess the timing chain guied broke a while a go that would explane my all of a sudden out of time situation an few months back.




Timing chain was starting to cut into the case

Indeed, Sir.

The crankshaft itself seems to absorb the impact you need to loosen these bolts. I simply removed the oil pan, and placed a wedge (my tool was an allen wrench) between the lobe of the crankshaft and the rib of the inside of the block. Next, with a little tension on your bolt, give the breaker bar a gentle strike with a hammer. This has always loosened these stuck bolts for me.

My super-secret, super-easy way of holding the crank in place to remove crank bolt:

Get some of that plastic line used in weed wackers, the thickest available. Take out the #1 spark plug, and run piston down to bottom deat center. Feed in 3 feet or so of plastic line in through the spark plug hole, making sure to leave a little sticking out for removal later. Turn motor counter-clockwise so piston comes up. The plastic is incompressible, so near TDC the piston will stop as the plastic line coiled up will be pressed in between teh piston and head. Remove bolt any way you find necessary. To remove the plastic, turn crank slightly the other way, and pull. It's soft enough to not harm your valves or head, and hard enough to not break apart.
