Getting more umph outta a cheap engine

[Reno badboy]

Yea, I guess a two stage system is a bit much for a Harley.(110-165) It does real neat things to pistons!!!(Valves too I guess!)( Oh yea,the rods also!) 16 over springer,rigid,jockey shift,3" open belt drive on a 100" stroker motor!

If you get an engine with a keyed shaft and have it threaded, you need to make sure the length of the shaft is correct and the shoulder on the shaft to be in the correct place on the shaft or the pump won't work on it since the impeller screws all the way to the shoulder of the shaft, the length of the shaft and where the shoulder is located on the shaft is important for the impeller to be in correct location within the pump housing.

Someone was telling me to other day that they owned a new Keene P-180 pump that fits a 5/8" keyed shaft, but I haven't called Mark Keene to find out if that is a fact or not, I would suggest calling Keene to find out, it would make a lot of sense for Keene to make a keyed pump IMHO, if it's a fact that Keene makes one now you would still need the shaft to be of the correct length and have the shoulder be correct as well, so that is another question that should be asked if you call Keene.

Lovejoy couplers fix it all as many configurations and ez to do-John

You're rite john a lovejoy would work.most all industrial pumps use them.Skip thats a good point when I threaded my 1in shaft someone post the spec's over on 49ers mikes back when it was tom ashworths.And they where the same as the threaded.One thing I can't understand is why all the pump manufacturs don't have the coupling stile pumps like I have on my 3-4-5 golddivers.Keyed or threaded works great and tons of room four the air compressure pully.

You guys are talking apples and oranges here.

A direct mount pump is lighter and cheaper to build than a pedistal mount pump. The space the direct mount pump takes up is smaller than a pedistal pump.
I happen to like the pedistal type better for maintence reasons, the bearing are stronger and easier to replace and seals will change easier as well. The belt to run the air compressor is much easier to change with a flexible coupling also. So I feel the extra cost and weight is offset. One other thing worth mentioning is that the keyed shaft motor is much easier to find if the motor dies out in the bush somewhere.
