[Rockhounds] Re: DP Genie parts

[Hans Durstling]

Hi all,

Just yesterday I dismantled and doctored a Genie which the owner 
acquired second hand. He says it is 19 years old. This is about the 
fourth elderly Genie I've disassembled. Based on that I'm inclined to 
think that a two year old Genie ought not to need parts replaced but 
more likely only adjusted.

In all cases the pump has been a problem upon reassembly. The belt 
slips, the pump turns slowly if at all making the spray feeble or 
absent. I've found two main causes for this. One is getting oil on the 
pump belt. This makes it slip on the pulley. (It is not humanly 
possible to disassemble clean and oil a machine like a Genie without 
getting oily fingers.) So corrective measure number one is to clean the 
oil off the reassembled pump belt with a series of Q-tips soaked in 
alcohol. It's hard to get at but it can be done. This restores the 
friction between belt and pulley.

Sticking of the pump elements and in particular the piston may also 
make the pump harder to operate & hence cause the belt to slip. The 
piston is a leather disc which fits itself snugly to the cylinder walls 
by dint of running. If you've had the pump apart  you will have 
"deformed" the leather somewhat. So it will at first jam slightly and 
will need to be run-in a little before it has conformed itself smoothly 
again against the cylinder walls. With everything cleaned, oiled and 
reassembled, run the piston in by turning the big pump pulley manually. 
  Stick a wooden dowell or pencil or something into the pulley holes to 
turn it. This is a good way also to turn the belt to clean the oil off 
all of it. And while you're at it also degrease the shaft where small 
pulley that drives the pump belt runs. This little pulley sits loose on 
the shaft. Only friction turns it. So you want to maximize friction at 
that spot, not lubricate it.

Hope that helps - and remember: your own Genie mileage may vary!

Cheers,
