I'm needing to raise my bike back up, which requires taking pressure off the suspension and I need to jack it up. The only stable spots under the bike are the bottom of the oil pan, or on the center stand brackets, other than that, there is the mount for the rear suspension spring.

Will i be ok by jacking it up on the oil pan?

What model bike? Generally a bike's oil pan can support the weight if you spread the weight out. Use a board to spread the weight out so that the jack pad is not putting pressure on just one small spot.

You can't use blocks of wood? One to span the reach and other to make your lift points the frame?

It's a gs500f '08
I had tried using blocks of wood before but the nuts wouldn't budge. Not sure if its because they were rusted over or what. I was suspending the bike at the bottom of the rear suspension link. It was a pain in the ass though. I'll try the oil pan idea and use wood blocks to spread the weight out.

In addition to boards, you may want to use some rags in the spots where the boards don't touch to spread the weight out further. The sides of the pan will be stronger than the middle.

If you need to use some force and you can't get under too well, you can lean the bike on its side somewhat against a sturdy support and have access to the bottom from an angle.

My CBR929 was virtually impossible to jack because of all the tupperware, exhaust pipes directly under the engine, etc.

So I borrowed an engine hoist and used a sling. Zero chance of it falling over or off the jack no matter how much force I needed to apply to something.

I tried again after applying liquid wrench, multiple configurations... but no success. I'm going to go out and get a torque wrench today and hopefully that will get me some better power and torque

Torque wrench won't help getting a bolt off, it is designed to properly install a bolt. You may want to get a breaker bar.

Dang good to know. This simple project is getting annoying. I'll look into that today, hopefully I can find it locally... otherwise I'll just deal with it and ride the bike as is for the next couple months

Since you seem to have some stuck bolts I have a few suggestions.

1) try using a cheater bar on your wrench or socket..this is a 2 foot or so length of pipe, you use it to extend the handle of your wrench to give yourself more leverage. You can go longer if need be..I recently set a personal record... using 12 foot! cheater bar made of 2 inch steel pipe on a 3 foot long pipe wrench to break loose some 30 year old 4 inch threaded iron pipe fittings here at work. I was standing on top of a big tank, had a helper on the ground with the other end at the wrench, it looked crazy but it worked!

2) Use a 6 point type socket, not a 12..this makes it much harder to strip the head of the bolt.

3) Get a helper to hammer on the wrench in the same direction that your pulling, often the shock will knock it loose.

4) Beg, borrow, or rent an electric ( or pneumatic if you have air) impact wrench ( the thing you see used to take car wheel nuts off), this will remove most stuck hardware easily.

Good Luck!!!

I like the extended wrench idea, someone above reco mended against the impact wrench though. They stated it was for tightening bolts , not loosening.

Oh shoot, I think I'm going to buy a torque wrench for general purpose throughout my bike and car, and I'll get the impact wrench if I can't get enough torque from my muscles using an extension bar. Thanks for the help, I'll report back once this is resolved.
