removing oil injection?

Looks to me like I can remove the pump and lines. Plug the fittings on the bottom of the case and build a cover for where the pump mounted. The case already has the holes for oiling the crank bearings.


Now the ?'s

does this sound feasable?
Has anybody done thiers this way or is it better to leave the pump on?
Any bearing problems going to happen with the removal of the bottom lines etc?

Thanks in advance .......................SRXtreme

PS 1998 SRX motor

The same can be done to the SX motor too?
 
I was wondering about doing the same to my viper. We've had two vipers in our group this year with failed oil pumps. Is oil pump failure very common on the vipers?
 
viper oil pump

I never really paid any attention to the viper pump but I would assume it is the same as the SRX pump. I am not removing the injection for any specific reason other than to open that area up where the resevoir sits. neater appearance and loose a pound or two. I have never need more fuel than what the tank holds so I might as well only carry what is needed. As it is now I only fill the oil res about half way.

I was told (and it seems logical) that you will not get enough oil to the outer crank bearings if you disconnect the oil injection.

How is that logical? The pump mixtures the oil in fuel pump...
 
That is exactly what I am wondering. The case is drilled to feed oil to the bearings from the top. I am thinking thier might be enough oil to supply the bearings from just what is put in the fuel 32:1 or thereabouts. The botom oil feed line has a restriction in them so I cannot see the pump providing that much oil to them. On another note I knew a guy that tried drip flow to the bearings but the motor sucked the resevoir dry. Well if I got time this weekend I will yank everything and try it. The worst case scenario is a couple bearings...........................SRXtreme
 
You'll need to richen your fuel mixture to compensate for the fuel volume displaced by oil in the premix

I don't think so as the oil is mixed in the fuel pump before heading off to the carbs.....................SRXtreme
 
Lawrence, there's mixed opinions on it, some guys like to drip feed it, but it seems to me like it'd be bigtime over-oiling in that case (like you said, suck the reservoir dry). I imagine it should work fine, and like you say, worst case scenario a couple of bearings, and it'll be the end ones that go (easiest to replace)
 
All you need to do is remove the pump and resivoir, make a block off plate, plug off line on very bottom of case, and the line on your fuel pump. then just mix your fuel 32:1 and you will have no problems. As far asa block off plate i machined mine out of a piece of alum. the same shape of the flat spot on the case, then drilled two holes and used to socket head cap screws. don't forget a gasket though. good luck and have fun.
 
you need to be able to add lubricant into the void where the pumps was in the case. it oils the bearing on the water pump. when you take off the stock pump, save the bleed line. drill hole in your new block off plate and attach the bleed tube after extending the tube length. this way you can add oil so your water pump wont fail.
 
From my understanding is once that cavity is filled before capping it is all that need to be done. Or does that oil eventually drain from there?..................SRXtreme
