Ashwamegh 25/2 : we are CLOSE now !
« on: November 25, 2018, 07:25:06 PM »
Today I had the opportunity to spend time with the beast.

Checked mufflers and intaked....no obstructions.....I did finally add
oil to the oil bath air cleaner. Remember those ?

Check injectors...looks like the correct numbers to
me ??

Adjust valves....I tried a few methods but wasn't happy...it started
and ran fine but I didn't think the intake had enough play so I did
the old slap and tickle at about 10k straight across.  Starts/runs
fine.
Check load for numbers.....yep, 4.2+ kw..... I am using space heaters and heat guns...checked each one and got the total.

Play with springs...The final spring wiil just hint at wanting to
hunt.....I can observe the slightest movent in the linkage but I
don't really hear a change in engine rpm.


But here are the numbers....

61.5 HZ no load
60.00 with the 4.3 kw load I run.

That is better than it's ever been....
man, I'm HAPPY with that !

I will need to do some more/better electrical work
before I try any heavier load testing.

I know everyone has been on the edge of your chairs with
anticipation, so I decided to spread the joy !

You aren't trying to tell us this was all down too  light gauge wiring that wouldn't carry the load properly are you?   :laugh:

That's great news, Gary.   Your patience and perseverance did it.

Well done Gary, lets hope she brings you many years of joy and electricity.

Great news! I'm glad it's working out. I know the frustration of getting the response dialed in....and the joy of getting it right is worth the trip!

Hello all.  I am a longtime viewer and have never posted but think I can add a little about the lack of power.

I have several Listeroids that power generators, compressors and stuff.  One of them belted to a ST-5 falls far short of expected output, but holds frequency and voltage great at less than full loads.  In dinking with it last week I found the governor pulls the rack and speed increases when the load is small, but at high loads and certainly at near full load the speed starts to fall off even though the governor has pulled to "full fuel" position.  I pulled the pins in the linkage and tried again to get full power by manipulating the rack by hand had no problem at all in pulling rated power  and beyond!  The situation is that the internal governor arrangement does not have enough travel to operate the rack both to no fuel and to max load fuel.

A solution that I'll implement is to lengthen the arm that operates the vertical linkage so that the rack can open further.  I believe this is a defect in this engine due to a poor copy of a Lister.  This defect does not exist in my other engines. 

Maybe other engines have this defect hidden waiting to puzzle their owners?

Thanks for listening,
George

Hi George, very interesting observation. I posted a while back some photos of a genuine Lister CS governor linkage and a modern Indian copy. the length of the linkage levers was wrong and the alignment with the rack was terrible. I chose to make brass bushes for the original rather than use the replacement. Still haven`t made any smoke as I am waiting for the cylinder to be sleeved.

Good work!
I too had governor linkage issues which turned out to be the spring tension and also a linkage that was binding (Alignment).

You are now ready! Caution.... You may find yourself praying for power outages.   ;D

Good News for You!
I have a similar Ashwamegh 25/2 w/ ST12 head. Last night we had a wind storm and the power went out a couple of hours before bedtime.
I just lit a pair of ISO-Butane camping lanterns so we could read books (remember those?) before bed.
BUT! Today I went to the garage and inspected / pre-lubed the Listeroid and lit it off for the first time in about 4 years. It took right off!
I ran it @ 3Kw on space heaters for an additional hour after the water temp got up to 200F (93C?)
I want to caution all of you twin operators that the 'off side' injector pump cam follower and the end of the cam run very dry. That housing does not have a supply of oil, so I plumbed in a pipe tee at the top of the oil pump and run a hose to a Frantz oil filter an direct the filtered oil into a fitting that dribbles onto the 'dry' cam. This cavity has a drain hole to allow oil to return to the sump.
I have added oil pump discharge pipes, out the block to an oil heater (small marine transmission oil cooler) that resides on the hot jacket water 'up' leg. Then a full flow oil filter and back into the block to dribble onto the 3 main bearings.
Now the oil is heated & filtered so I don't worry about using detergent oil.
I went thru the governor spring routine, as with you, the final result was good. I'll be looking into the 'full governor travel' George mentioned.
My 25/2 was set up and run at 1000 RPM initially, but it was pretty twitchy, and with the poor governor springs would overspeed when load was reduced. It shook so bad it broke mount bolts and was generally scary. I considered that too be too risky so:
I got a smaller gen-head pulley, which reduced engine speed to about 735 RPM (too bad, smoothest was about 910 RPM, but no pulley available in that size) My measured Max Output is 9.6Kw blowing black smoke and squeaking the drive belt!

Hey SHIPCHIEF have you considered balancing those flywheels - there's a lot of info on here about that; and substantial improvements to be made I believe

Mike and All;
Without any education or knowledge, I added weights to either or both flywheel inner rims, including a big old crescent of lead I cast for the purpose. I never achieved satisfactory results.
I should look that up.
However, I now have access to a DynaVibe propeller balancer which has an accelerometer and a a timing strobe.
Truth is: I don't need 12Kw and I've grown to like the current speed & fuel consumption. It performed well during the February 2007, 5 day Ice Storm blackout.
I would like to see it run even smoother and a bit less clanking... :P

Hi 'Cheif

I'm liking the idea of using an oil cooler the 'other way round', there's lots of stuff on here that refers to the Lister's oil temperature being on the low side.

As the crankshaft on my CS was badly worn I had the big end re ground and replaced the mains with taper roller bearings - and plenty of Loctite 620 -, thus removing the need for the oil pump. I re routed the oil pipes to 'squirt at the TRB's even 'tho it's not necessary (Follow 38 ac's tip of removing the inspection plate after a run and see how much oil has been slung around the inside of the crank case by that little dipper)

Re running the plumbing and heating the oil before filtering and sending it back to the inside seems like a great idea.

Cheers
