97 Disco Bottom End Rebuild
 

Just starting a new thread for the bottom end rebuild as to not clutter the HG one.

Does anyone know the size of the crankshaft pulley bolt? Can't find in RAVE. I assume the pulley must be removed before the front cover can be removed. Right?

As usual, I've got an opinion on this. You would pick the strongest torque on the engine... see https://landroverforums.com/forum/di...ighlight=crank

Always up for more tools.

Wow 185 ft-lbs! No one says the socket size though and RAVE doesn't say either. It's bigger than any socket I have.

Remember you're one of the guys who suggested replacing pumps and rings! :)

Not sure of the size but you usually need one heck of an impact gun to break that bolt loose. You'll need yourself a harmonic balancer puller as well if I'm not mistaken.

Amanda & Dustin - please read the posts that were attached, there are several ways to remove that rascal without an impact wrench. The Spike method of wrench on ground and bump starter is cheap and quick.

Nut is 15/16. Just tried my breaker bar/belt wrench combo. Belt wrench slips. I'm past the point of being able to use the starter aren't I? Wood or pry bar on the crankshaft seems like a really bad idea.

Just a quick note about sockets. One of the few good deals I have gotten at Harbor Freight was a set of larger deep well IMPACT SOCKETS. They are a heavy construction, not chrome plated, will take a lot of torque since they are made for impact wrenches. They do come in larger sizes, which I needed for changing my rear drive shaft over to a 98 to get away from the damaged rubber coupler.

Like Buzz and Spike have let us know, there are some simple shortcuts. I have used a simiular technique where I placed a hydraulic jack under the breaker bar and jacked a nut or bolt loose. A little more control and finesse than the bump starter method.

Whatever you do, keep it as square as possible (socket to nut).

Here's what I did:

15/16 6-point 1/2 drive socket + breaker bar + cheater bar + vice grips + old belt wrapped around water pump = crank bolt off easy

Young man, we shall have to make space on one of the branches of the shade tree for you. Well done!
