Crankshaft pully bolt Sign In

I have a 1987 Toyota 4Runner 2.4L Turbo with automatic trans( hate them). I just replaced the crankshaft seal belts, waterpump. My problem how to keep the crank from turning while torqueing the bolt. The trans inspection plate you have to remove the tranny to remove it. I have the belts tight for now and have used sockets with other ratchetts on power steering pully bolt and alt pully bolt. Im out of ideas please help. Also no air tools.

Will probably take a helper but you should be able to lock the "flywheel" with a pry bar to get the crank bolt properly tightened - may have to remove starter or could use a dust shield - dunno for sure on that one but that's a way to do it,

I confess .In the v8 days a burp with the airgun worked , never had a failure . However , when the eng's got knocked sideways there was'nt room for the gun and/or the torque value was lower than i could get gun adjusted to. This is a way when you dont have access to flywheel like this one.Remove #1 plug, turn eng to TDC #1 cyl. Take a length of 1/8 inch dia cotton clothes line . turn eng slightly either before or after TDC depending on crankbolt being LH or RH thread. Feed in lne till cyl is full. Carefully torque bolt .Back eng up to relieve pressure . Take out line.

Matco tools has a tool for this purpose that I believe is called the crankstopper. It threads into the spark plug hole and stops the piston from continuing in its travel. remember to take the thing out before you try to start the motor. Sounds dumb, but I've seen in happen when people get distracted. I don't think it costs too much for it.
