ISX rear main seal install

[JMBT]

Quickserve says not to use any lubricant when installing the rear main seal on the ISX motor, instead to use a 10 percent soap solution? 10 percent, thats pretty specific. yet they do not specify what kind of soap, and I guess we are mixing it in water?

Any experience with this soap mixture? Or is there a product or sealant of some kind like is used on the front main seal?

Thanks

I usually shake up some water with a little bit of truck wash or windscreen washer additive. No need to be specific about the soap ratio. The idea is to make the rubber slippery for a few minutes without introducing petroleum based fluids. The soap dries once the seal is in.
