If its the fuel pump it seems like they should work no mater how they are mounted.

General Discussion / On the Level?
« Last post by mswyka on March 17, 2024, 02:41:10 PM »
Good afternoon.

I am installing a new pump in a sled and am wondering if the pump must be installed level?

Does anyone know of a reason that pumps must be level?  Or, is it possible for me to mount the pump on an angle and still have it operate properly?

Appreciate if anyone has any experience with mounting pumps askew.

The gear on the crank should be tight to the crank.  If the one you have spins likey you will need a new gear.  I should have one if you need it.

One more question about the oil pump gear on the crankshaft. Is this gear supposed to be press fitted to the crankshaft? For how loose this gear is (spins freely) I can't see how this would drive the oil pump.

Thanks in advance.

Some of them I could hammer out, but not this one…. I put it in the 20 ton press and pushed on it until it started to flex into an S shape.  I even tried a sledgehammer.  Acid is the only option for this one. 

I read that the acid can be neutralized with baking soda, so that’s what I did…Even though I’m not sure the weeds will grow in my driveway either…

Sounds like you are close to a solution.  I initially tried hammering them out.  Then drilling them out - but I could never keep the drill straight.  So the acid was the best option discovered so far.  If you have a way to boost temperature that could be a help.

As far as disposal, lets just say that there is a spot in my gravel driveway where the weeds won't be growing for some time.

I don’t have a good way of getting the temperature. 

I left it set for another day, but it’s not enough.  My local store was out of the gallon jugs so I got 2 quarts, hopefully it’s enough to finish it off. 

What did you do to dispose of the spent acid?

Did you measure the temperature of the acid bath at any point?

I had bought two versions of acid, one was the green kind.  This is the first one I tried and found not to work well at all.  I tried the standard acid with MUCH better results.  However it seems to be taking quite a long time, must be due to the cold temps outside.  After 24 hours in the standard acid it removed several inches of shaft and was still bubbling consistently.  I’m hoping with enough time it will remove the rest of the shaft so I don’t need to buy another gallon.

Good morning.  Wow, not sure that I ever timed the reaction.  What I can say that it was on the order of hours and not minutes - but definately less than 24 hours.  I think that the biggest problem is that of surface area as only the end of the shaft is exposed to the acid.  If I could I would probably use something like a peristaltic pump to circulate the acid bath into the end of the suspension arm.  I also found that temperature plays a big part to how well and how quickly the aluminum was disolved.  The higher the temperature the better.  The reaction is exothermic which helps raise the heat but out of doors in the winter the heat of reaction may not be enough.
