Engines / Re: CAV fuel pump repair/parts
« on: August 18, 2022, 12:08:21 PM »
Because it is a standard and readiliy available pump virtually and diesel fuel injector place can rebuild and set them for you. It does require proper instruments to set the pressures so if you dont have a pop off tester then take it to a specialist.
As another option being on the rivers over there you must know of some boat repair shops on the river, they too can help.

I agree that over time springs do loose some pressure, especially if it was compressed after shutting sown last. You mentioned to add a shim to lift the pressure but to me that sounds back to front. If it has lost pressure I thought you would remove shim/s.

We have a product here that looks the same but is made of stainless steel and is called a scourer. Mainlu used in washing up. They look like a neat ball from new but then flatten out and eventually will look like yours. I have heard of timber floor treatment being done that way but never seen it.

Hi VP, I think the steel wool may have been an air filter not a tool.

For many years we set spark plug gaps to a hacksaw blade an points by the look of the gap. The kitchen knofe must have been one of the older types with the thin carbon steel blade not the thick stainless steel blades.
I have a couple of the old high carbon steel blades that actually were a butter knife but I run them on the oil stone and they make the best sharp knives in the kitchen and hold the edge very well. So if you see some in an Op Shop grab them and try it.

Take a visit to Pearns World, there is a heap of toys to choose from, just not for sale.

I stripped down a tractor engine that had the cam gear replaced. Same size gear but diesel version of the same engine but 90' out with the timing marks at TDC on #1. So I made my own marks to be certain. I knew I was on TDC as the rotor button was facing #1 and the cam lobes were away form the cam followers so I marked everything up at that point.
It was not until later that I found out about the difference between TVO and Diesel cam gears. Very glad I took the steps I did as it made assembly so much easier.

Try not to be hard on yourself. We have all made mistakes and by doing so we learn by them. In time we hope to see some more progress as it happens. Stay calm and continue with the great work you are doing.

OOPS big time. Sorry that this has happened after all your very hard work in collecting it and stripping it to this point. Do you think you will be able to get another one?

General Discussion / Re: Quick question

Nice little and very reliable engine. As for value it is an age old question which for me comes down to supply and demand. Have a look at the usual auction sites in your Country to see how many are for sale and how long they have been listed and what they sell for as well.
I cant put a price on it at all as I have not looked for one but sometimes when I have an item I want gone if I get my money back for it then good, if not how much am I prepared to loose on it if anything and hold onto it until the price rises. The good thing for you is that you have confirmed that it starts and runs so that is a huge benefit to buyers. As a suggestion do a YouTube clip of a start up and run which will confirm what you say in your advertisement. It presents well so anyone with a footpath roller, boat and then marinise it, or depending on what RPM it is governed at a good standby engine for a genset.
Wish you well selling it.

Nice one. Good luck with the sale and hope it goes soon.

if your injector is the same style as in reply 23 then pressing it out from that side appears to be the way to go. Keep soaking and a small amount of pressure and maybe introduce some heat. Even heating and spraying with WD40 to get it to draw in deep and quicker. If still no joy then more heat is how I would aproach it

12
It can only be a guess to say yes push down on the pre-combustion chamber to push the injector out but I would also want to make an adaptor o fit under the injector so that a small amount of lift could be applied as some pressure on the pre-combustion chamber. Again I woul make an adaptor that would fit nicely around the chamber but not touch the raised section.
Lots of pre-soaking and maybe some or a lot of heat to assist in it's removal.

Well done on the recovery og this special little engine. You may be surprised at how little it will need to run again. As stated, what it looks like on the outside may be bad but inside still good. Thanks for the pictures.

Good advise Bob and some easy things to check. For me I would still want to see the fuel atomising on all injectors. To answer the question of compression testing, yes it can be done but you will need the adaptor to fit into where the injector would normally be.

If injectors and pumps are good and you have confirmed that they atomise the fuel by hooking them up while outside of the engine and cranking it over then maybe a valve. I suggest you check they are atomising because there may be a problem/blockage in the fuel lines.
I just had a thought. Is this a 3 cylinder engine as it is listed as a HR3? If so have all injectyors and pumps been serviced?
