Engines / Replacing expensive old imperial bearings
« on: September 11, 2019, 09:49:39 AM »
Hi Guys, a while back I posted about an issue I was having with finding vintage Timken tapper bearings for an early 1950`s Cooper petrol engine. The bearings were available if I was prepared to cough up $350 each plus delivery and taxes. Rather than dump this nice vintage engine I decided to modify the crank shaft and housings to accept modern metric size tapper bearings. A lot of searching on bearing manufacturers web sites and a lot of phone calls to my local bearing supplier and I found NTN 32210 bearings would be an adequate replacement.

The outer diameter of these bearings is about 1.5 mm larger than the original, while the internal diameter is about 10 mm larger than the crankshaft, the width of the bearing is about 2 mm less than the original, a big issue with adjusting the end float! The load rating and life expectancy of the 32210 is a little lower than the originals but since one of the originals was still serviceable after 60 plus years I will have to live another fifty years to wear them out, not very likely but I live in hope!

The two housings have been in the lathe and bored out to take the 90 mm cup,  I have turned up two bushes to to enlarge the crank shaft from 1 9/16" to 50 mm, these have a 2 mm flange to allow for the difference in bearing width. This allowed me to cut gaskets to bring the end float back within tolerance.

I have posted some pictures, hope this will help someone in the same situation.

Hi Guys, found this deceased estate sale while searching for information on my Cooper XD lighting plant: https://petermilling.com.au/clearing-sale-2/24/

Hope there are a couple of cashed up Australian engine collectors who might be interested.

Everything else / Macksville rusty iron festival
« on: September 01, 2019, 09:23:00 AM »
Hi Guys, sorry for not posting much recently, been busy. I have been at the Macksville rusty engine rally. The call went out, last year, to beat the world record for the number of old stationary engines running simultaneously. The previous record was held by South Africa with 207 running for 10 minutes. Today Australia managed 333 old stationary engines running at the same time for 10 minutes! We could probably have got close to 400 but we had a few non starters. I will probably be coughing up the fumes and smoke for weeks to come.  :laugh:

So I guess that throws out the challenge to those of you in the rest of world, can you do better?

Bob.

Everything else / Antique generator control unit
« on: August 24, 2019, 10:34:29 AM »
Any one know what this is? (see photos) It appears to be some sort of a generator control unit, It has start and stop buttons and a large variable rheostat to adjust field winding voltage and thus output voltage. Found it in a pile of scrap in an old guys shed, gave him $30 for it. Any info much appreciated.

General Discussion / Brexit
« on: March 31, 2019, 09:20:40 AM »
As a Brit living in Australia I have watched the total paralysis of the UK government with a mixture of shock, horror, despair and disbelief. I am damned glad I live where I do, I would hate to be ruled by these idiots. I think the attached photo of the UK Prime Minister sums it up.

Things I want to Buy / Cooper engine circa 1925
« on: March 18, 2019, 10:44:32 AM »
Hi Guys, I had a very interesting outing with a mate of mine who took me to a shed in the middle of nowhere. The owner of this shed collects antique diesel tractors, he has dozens, all of which he has painstakingly restored to as new condition!

He also has a few old stationary engines which I would be interested in buying, so does anyone have any idea what a Cooper/Stover petrol engine made in the 1920`s is worth? See photos.

Other Slow Speed Diesels / Armstrong Siddeley 10 HP diesel engine
« on: February 24, 2019, 06:40:04 AM »
Hi Guys, I had a mate turn up today with an engine I have never seen before. It is a single cylinder Armstrong Siddeley 10 HP air cooled diesel. It is in remarkably good condition for it`s age, it turns over but has low compression (probably valve seats judging by the air hiss). I have been invited to help with the restoration of this beauty so if anyone has any information please get in touch. In return I will post pictures showing the internals of this beast, on the forum. I have posted a couple of pics to get your attention.

Other Slow Speed Diesels / Southern Cross ETB diesel engine
« on: February 13, 2019, 12:28:10 AM »
Hi Guys, I am awaiting the delivery of a Southern Cross ETB 2.5 HP diesel engine. Manufactured in Australia circa 1950, they were also manufactured briefly in South Africa. This engine has sat in a mate`s shed for the last 20 years. I have finally persuaded him to part with it for free!  :) 

Sadly it is incomplete, missing the fuel injector, pump and fuel lines. The originals would have been made by an Australian company called Pyrox, who manufactured injectors and pumps under license from Bosch.

I have been unable to find much out about the missing items but believe they are very similar to the units used on a Lister CS 3/1. I suspect that I might have to change the injector nozzles and fiddle with the pop pressures a bit to get them to work properly. Any thoughts please?

I have attached a photo of a complete ETB I found on the internet, probably a breach of someone`s copyright, for which I apologize in advance. I will post photos of my unit once it arrives.

Don`t see one of these every day. Never been run since manufacture. $5000 is way too rich for me but as a collectors piece it is probably priceless: https://www.gumtree.com.au/s-ad/warwick/collectables/vintage-lister-diesel-engine/1207228263

Hope someone can find it a good home.

General Discussion / Solution to lack of age care places in Australia
« on: January 15, 2019, 06:50:51 AM »
Hi Guys, my wife just received a text message outlining how to get around the shortage of age care places for the old and infirm:

Say you are an older senior citizen and can no longer take care of yourself and the government says there is no Nursing Home care available for you. So, what do you do? You opt for Medicare Plan G.
The plan gives anyone 75 or older a gun (Plan G) and one bullet. You are allowed to shoot one worthless politician. This means you will be sent to prison for the rest of your life where you will receive three meals a day, a roof over your head, central heating and air conditioning, cable TV, a library, and all the Health Care you need. Need new teeth? No problem. Need glasses? That's great. Need a hearing aid, new hip, knees, kidney, lungs, sex change, or heart? They are all covered!

As an added bonus, your kids can come and visit you at least as often as they do now! And, who will be paying for all of this? The same government that just told you they can't afford for you to go into a nursing home. And you will get rid of a useless politician while you are at it. And now, because you are a prisoner, you don't have to pay any more income taxes!

Is this a great country or what? Now that I've solved your senior financial plan, enjoy the rest of your week!

General Discussion / setting up a community enginre bank
« on: January 04, 2019, 10:26:30 AM »
Hi Guys, it`s coming on council clean up time again, this is the time of year when you can put out busted machinery for recycling. I am considering setting up a Community project where I fill a shed with second hand equipment that can be rented out for next to no money, while their own equipment is being repaired.

I already have a collection of pumps, pressure washers, whipper snipers, lawn mowers, chainsaws and ride on mowers all of which have been dragged out of the bush and fixed for little or no money. People today are hopeless, they have no experience in either using or maintaining equipment and consequently throw out perfectly good stuff which ends up in landfill. Today I was given a pressure washer that does n`t work, a quick inspection shows that it stopped because the low oil level mechanism turned off the magneto coil. Further inspection suggests that the engine has probably run for 5 to 10 hours max.

Would this business model work? How much should I charge for second hand equipment hire? I`m a good engineer but I`m a lousy businessman and my health is shakey at best.

Thoughts and advice please,

Bob

General Discussion / Motor oils
« on: January 02, 2019, 06:50:04 AM »
Hi Guys, with it being so hot here at this time of year I have decided to stay undercover and do a little maintenance work on some of my lawn mowing and other small engine equipment (oil change, filters etc). I have a range of engines from Honda, Briggs and Stratton, Husqvarna and the inevitable Chinese Honda clones, all four stroke.

Not too surprisingly I can`t find most of the service manuals so I did a very quick search on engine oils on the internet. Every single manufacturer recommends their own brand of 10W-30 detergent oil for all of their air cooled engines, regardless of whether these engines have oil filters or not. All at a vastly inflated price over regularly available 10W-30 engine oils.

The one manual I did find was for my GX-165 Honda clone pressure washer. This engine has no oil filter and the recommendation is for a non detergent SAE 30 oil.

This makes perfect sense to me as I don`t want a detergent oil keeping any detritus in the sump in suspension. Can anyone explain to me why all the western manufacturers are advocating their own branded detergent oil for engines without oil filters? It`s almost certainly made by one of the big petrochemical companies and just bottled with a different label.

Yes I know this is a diesel engine forum, so stop throwing things.  :laugh:
