oil injection pump

[KruZer]

im probably bringing up somthing old, but my 84 spree's injection pump has failed, i bloked off both oil lines and am running pre mix, however the pump will not stay put. How do i get the pump to stay secure??? Note: i removed the shaft from the pump to avoild it trying to pump oil

new o-ring, tighten the bolt that holds it down, and grind the teeth off the shaft and put it back in there

the o-ring SEEMS tho be in good shape, i can barley get the bolt to tighten down, never thought about grinding the teeth off the shaft. There are threads at the end of the shaft that goes into the pump itself, but does not thread into anything, the pump literaly blows itself off the block on startup, would the shaft not threading into anything play a part, or do i just need to grind the teeth down??

The hold down bolt hole threads are striped. Either Heli-coil the hole or thread it to the next size up.

there is no hole there, its a retarded slot that you slide a nut into and then thread the bolt in from the top, would zip ties work??

LOCTITE!

you can also try to find another small nut to slide in the bolt down space and a corresponding screw, if too long just cut the screw to the right length
