Default How high?

Hi,

I知 about to lower the entire rear suspension and while I知 at it I知 planning on replacing the transmission with a lower mileage unit. I do not have a lift at my place; will be working off of the garage floor. How high off of the ground do I need to have the lower pinch rail in order to be able to lower these two major pieces?

Thanks

wj

Hi wymjym,
Sorry I do not know about the Transmission clearance requirement.
However, I can confirm that to remove the rear suspension (as an entire assembly) in the way that you describe, you will need axle stands raised to a minimum of 380mm at the rear jacking points. .This is with the front wheels still on the ground so giving a higher rear bumper elevation. See image of this exact set-up. This clearance allowed me to use a portable Motorbike scissor-lift to lower the IRS assembly and drag it out.


Hope this helps.

Thank you!
How low does your mc lift go? or rather how much vertical space do I need for the rear assembly?
Thinking I can raise the rear 500mm and the front 150...the angle would be quite similar and give me a bit more room to maneuver.

wymjym,
My Motorbike Scissor lift collapses to 95mm high. However, I also had a piece of 30mm thick wood on top to protect the bolts (see pic). That 125mm combined was enough to support the center of the whole IRS assembly and with the wishbones / hub carriers hanging down on both sides.
I think your lifting plan will work. The overall vertical clearance required (Ground-to-Spare Wheel Well) to drag out the IRS is approx 400mm.

thanks again!
I'll crawl around and make some measurements...do you have any idea how much weight I'll need to support?
I was planning on using a low bodied transmission jack:

Maximum Working load (lbs.) 450 lbs.
Minimum height (in.) 7-1/4 in.
Maximum Lift Height (in.) 23-1/4 in.

do you think this will work?

wymjym,
Actually, the IRS is a really heavy assembly even with the Brake Calipers and Rotor Disks removed. I just don't know what the actual weight is.
I think your Transmission lift rated 205kg (450 lbs) will be at it's limit and not worth the risk.

My Motorbike lift (shown) is 500kg rated (1100 lbs) and was hard work to wind but managed both the lowering and raising. They cost about 50 Dollars.

Billy,
I appreciate the response but that is pkwise's jag...mine looks terrible due to a leaking front seal.
I hope mine does look that good when I'm done with it.
