Engines / Bryce pump for Petter
« on: March 23, 2023, 01:34:42 PM »
Hi,

Trying to rebuild the pump on a Petter AV1 series II (don't know if early or late).
Pump is labeled A1AA70/5S99.

Is this pump appropriate for the application?
Oldengine archives say it should be A1AA70/5S111H if early series II, or A1AA70/6S177H if later series II.

Engine is/was running before I removed the pump for rebuild (leaking at the base).

My original question here..

Listeroid Engines / Leaking Bryce pump
« on: September 28, 2022, 06:45:11 AM »
Hi,

The Bryce pump on my Petter AV1 leaks slowly. If I leave the fuel shutoff on it leaks about a cup of diesel every 10 days...

If I shut off the supply, I would have to purge the system If I don't start it "soon", meaning within 2-3 days.

Sound like the element needs replacing? I don't know if delivery valve would also cause it?

posted here as this forum is more active...

Generators / Do Petter AV1/AVA1 or Petteroid have flicker/waveform problems?
« on: September 26, 2022, 12:17:16 PM »
Hi, As the subject line asks.

I would think/hope that 1500 rpm generators based on these engines would
have acceptable flicker/waveform as boatloads were sold/still selling? over the years.

I really don't want to get into the Lister CS base flicker problems.

Would appreciate some feedback.

regards,
Nick

Anyone the composition of HOYT #14 babbitt, or white metal, and would it be appropriate to line big end bearing shells?

Original Lister Cs Engines / 116 mm piston
« on: April 01, 2022, 12:46:56 PM »
Moving on to the pistons, I was surprized to find they measure right at 116mm.
Is this common, and more important are there rings available?

I will need this sorted before final boring/honing of the aformentioned sleeves.

Original Lister Cs Engines / CS big end bearing failure analysis
« on: April 01, 2022, 12:06:48 PM »
Here is the big end shell that had substantial slop in it. While difficult to measure accurately,  I'm
getting about .65 - 0.82mm clearance.

I've yet to check for runout and taper on the crank throw with a mic but with a caliper
I think that even a 0.040 under still would be too loose,

Cant believe that this was hacked like this.

Note:
total lack of oil grooves
the oil feeds of the top shell babbitted closed
delamination of babbit (could be simply lead)
bad/no tinning of shell

The other shell, IIRC had no noticeable slop, but the top oil feeds are clear on that one

Alas,

Original Lister Cs Engines / Laystal liners
« on: March 29, 2022, 12:49:09 PM »
Hi again,

Do Laystal liners still make chrome liners for the CS? Any experiences here?

I saw this post and wonder if I could get a clarification, reply 20 by listard-jp2

Original Lister Cs Engines / CS cylinder repair
« on: March 29, 2022, 12:20:29 PM »
Hi all,

This cylinder is from my early 10/2 that I've finally started work on.
There is a fairly deep (~2mm) ridge from water damage I'm guessing. The ridge is about 5 inches down the bore.

While I know about re-sleeving, could this ridge be brazed with bronze or brass? and then bored and honed to size.
Cook the cylinder on the BBQ and the braze...

I'd like to keep the chrome on the cylinder as much as possible. The other cylinder seems to be fine.

I would also think that 5 inches down the bore the is minimal combustion pressure, temp as, IIRC, the power stroke ends at about 50* in a 4 stroke...

I am also contacting a firm here that can spray the ID and finish to size..
They say they can spray whatever metal is desired (e.g. chrome based) etc...

regards,
nick
PS This will be a working machine

Generators / Is a Petter AV1 a suitable generator for inverter input???
« on: August 04, 2021, 12:51:00 PM »
Hi,

My backup gen, 3000RPM 6HP Robin, Sincro 6KVA, low distortion head, capacitor regulated is often NOT accepted by my Victron inverter as an AC source, to switch to battery charging. The max load here is 100A at 12-14 VDC, whichI feel is quite within the capacity of gen system. No voltage drop/hunting.

All other AC loads run w/o problem, washing machines, driers etc.

I've set all parameters in the Victron to accept wide voltage and "bad" quality input.

My main, army surplus generator, currently being rebuilt/fixed has no prob. DEUTZ aircooled twin w/ massive 6KVA head, AVR regulated.

To the point,
The gas consumption is killing me w/ the gas gen. I would like to swap the alternator over to a Petter AV1, 6HP at 1500rpm I have that's running great.

Would this Petter be acceptable in this scenario? Would hate to fab everything, make pulleys etc. and have the same problem.

I ask as it "seems" that many one lunger engines have power quality problems unless strapped w/ huge flywheels etc.

regards,
nick

Engines / Petter AV1 Series 2 valve clearance?
« on: June 14, 2021, 02:07:11 PM »
Hi,

As the title asks. I've set them to 0.007" i/e, based on the Series 1 manual floating around.
Do these also have the wick in the rocker shaft?

tx,
Nick
