Engines / Re: Cracks in piston insert
« on: January 22, 2018, 03:28:38 PM »
I guess it's hard to say whether these pistons will hold up or not. I have six pistons that all have fractures and none have failed. No one has come forward stating they have seen pistons fail from cracks in the combustion casting, so I will run these piston with oversize rings...

Thanks for the replies ...

Thanks for the replys...

 All three pistons had a build up of yellow cake on top of the iron center insert, it had the consistency of plaster. The center piston had the bottom oil scraper ring broken.
 I guess these piston are no longer servicable, really is  bummer, was planning on going the route of oversize rings, ring gap is .032. Not sure what to do now, have already sandblasted and painted the engine.

Hi

 Is it normal for lister pistons to have cracks in the steel inserts in the piston tops. I have a Lister sl3 and have noticed all three pistons have multiple crack in the steel insert in the pistons.

Thanks again Starfire for your reply...

 It turned out to be a real easy fix, the ring that holds the brushes has a wedge in it that is attached to a nut. Backing the nut off loosens the ring, so I was able to turn it to match the placement of the brushes to the green generator. Now with no load I get 115v at 61hz, and at 10.5amp load I am getting 117v at 60hz.

 The name plate on the dog house on the fatboy is Panther Ranger and has a date code of 1955.

 Thanks for the help....

 Thanks Starfire for the in-depth reply.

   I had another look at the brush placement between the two fatboys, with one having the small brush holder pointing forward and the other in the opposite direction there is a 1 1/2" offset to the brush locations. The Big brushes holders point the opposite direction of the small.

 There is a tag for direction on the generator that indicates it was made to operate in the opposite direction then it is setup to run now. The generator was made in 1955 and the SL1 that is powering it was made in 1960.  So would running the generator backwards cause this issue, I have a multi meter but no oscilloscope.

The grey fatboy is the one that needs help..

 I have another fatboy on a sl1 and have restored another as well both of these with the same 10amp load drops about 5v under load. The small brushes are getting about 3v per pole. The fatboy with the large voltage drop the small brushes are getting 17v to one pole and 5v to the other pole measured at the brushes.

 The other fatboy I have here has issues as well, it has a dead short across the starting terminals. It will not produce ac voltage unless 12v is applied across the resistor terminal for a second, then it produces ac fine. Both of these generator where purchase from the same fellow and seem to have been worked on together(same wire crimps)

 Noticed today that the 4 small brush holders are pointing counter clockwise, looking at other fatboys they all seem to be pointed clockwise.

Lister Based Generators / lister fatboy voltage sag
« on: November 29, 2017, 11:48:40 PM »

  I have a mid 50's 2kw fatboy, no load voltage of 133v-62hz and with a 10amp load voltage drops to 110v-60hz. It is 8 dc brush head, 4 large brushes and four smaller. The 4 smaller brushes are connected to two wires these are the are attached to a resistor. I was under the impression that the resistor connected to the smaller brushes was to adjust for voltage drop, it seems to be providing all the current for excitation. If the resistor is disconnected voltage drops to 2v. When the generator is outputting voltage it is producing 20vdc from the ssf winding.

 Any thoughts...Thanks

Thanks for the reply.

   I found a autotransformer that would do the job, VICTRON 120/240V 32/100A autotransformer.

 This is a transformer for step-up, step-down and split phase output balancing purposes. The step up and step down part is easy:  Input can be 120 Volts and output 240 Volts or input can be 240 Volts and output 120 Volts.  Regardless of the input voltage the input current is limited by the built in breaker to 100 Amps. The split phase output balancing is a bit more complicated to understand:  When the input is 240 volts you can have two 120 volt load groups with a total output of the full 100 Amp rating regardless of whether the loads are balanced or not. The transformer automatically takes care of the load balancing.  See the links below for more details:

Autotransformer  100 A
Input/output voltage  120 / 240V
Input circuit breaker  100 A two pole
Frequency  50/60Hz
240V to L1,L2 current  32A
Neutral current, 30 min  32A (3800VA)
Neutral current, continuous  28A @ 40ºC/100ºF
Transformer type  Toroidal
Enclosure  Aluminium
100 Amp Input circuit breaker  included
Protection category  IP21
Safety  EN 60076
Weight   13.5 Kg
Dimensions (h x w x d)   425 x 214 x 110

Generators / 1959 FR3 with Kato Head
« on: November 25, 2017, 09:14:14 PM »
 Looking at maybe purchasing this generator setup, it's a 1959 Lister FR3 with a Kato generator and a Mechron power panel. The tag on the generator head lists it as 115V and 122amp. This to me could be the deal breaker, as a backup generator I would never need 122amps at 115v, mini split heater and water heater need 220v.

Do you think this generator head could be configured for 120/220v. Or is there a way to transform to 120/220v.

Already have a Lister sr2 with a kohler 6.5kw head and a Lister sl1 2000w 120v for backup power.

I would pass on this Lister FR3 setup but the guy wants less then 1k for it. So I am trying to find a need for it, save it from the scrap yard.

Any thoughts...Thanks..
