muddy Posted March 26, 2023 Author Share Posted March 26, 2023 Unfortunately there's quite a change in shape on the side of the block so a plate won't do it. Im mulling over whether to waste more time with some JB weld or similar or bite the bullet and get a new block. 2 hours ago, L19MUD said: Not good news but loving the way to get the engine on its side!

smallfry Posted March 26, 2023 Share Posted March 26, 2023 Definitely caused by block not being uniformly hot enough. JB weld might surprise you, but I would looking for a replacement block. Quote Link to comment Share on other sites More sharing options...

Bowie69 Posted March 27, 2023 Share Posted March 27, 2023 So it adhered well to one part? Quote Link to comment Share on other sites More sharing options...
elbekko Posted March 27, 2023 Share Posted March 27, 2023 Grind out all of the cracked material, clean up the edges properly (you may have to boil all of the oil/coolant out of it), grab a sheet of cast iron, and braze it in. Preheat with a torch and let it cool down under a bunch of fire blankets. At least that's what years of watching people do it on the internet has taught me Quote Link to comment Share on other sites More sharing options...
smallfry Posted March 27, 2023 Share Posted March 27, 2023 What sort of engine is it ? I will ask around here to see if anyone has anything. Unless you decide to go the six pot route ! Quote Link to comment Share on other sites More sharing options...
muddy Posted March 27, 2023 Author Share Posted March 27, 2023 It’s a Perkins Ad3 I believe, I think I can get a brand new block for £350 I just need to make sure it’s the right one. If it is I will probably go this route for ease, I’m a little bit sick of this ‘quick’ project now. Plenty of other things to be getting on with.

landroversforever Posted March 28, 2023 Share Posted March 28, 2023 Patrick Edwards in Oxfordshire would be worth a shot if don’t have any luck sourcing a block. Quote Link to comment Share on other sites More sharing options...
Popular Post muddy Posted March 21 Author Popular Post Share Posted March 21 A year later and it was the tractor run again last Sunday. A few months back a friend gave me a direct injection engine from a compressor or roller that had been sat out with no injectors and the head sat on loosely. I cleaned it up and left if for a month or two with penetrant in the cylinders but it was seized solid. Anyway two weeks ago I commenced tear down, found the bottom end to be in good shape so pressed some new liners in and rebuilt it with parts from both engines, added a nice dual display smiths capillary oil pressure/coolant temp gauge, repaired some wiring after a mouse has nested under the dash, re bushed the front axle pivot and added some wear plates to the PUH. Just a word of note the original delta engine is an A3 indirect injection and the new one was an AD3 direct injection. whilst basically the same the are very much not and a 'quick' rebuild and throw together turned into 4 days of head ache and hassle. Noticeable differences are between the rear main oil seal the AD being a modern lip seal, this means the rear main cap and crank are different, the seal housing is a bigger diameter than the rope variant so your backplate won't fit and the rear main cap is also much wider so the rope seal sump doesn't fit. Of course my 'new' sump was a different shape so I had to modify the front axle mountings on the tractor. The cam is also slightly different having a drive on the rear, the AD3 has an extra row of headbolts on the edge that need plugging in the top of the block (BEFORE you fit the head......) , dipstick is now on the wrong side just to ruffle some anoraks and of course every Anyway it completed the run without fault so now to blast and paint the wheels and work out why the brakes have no bite. Backplate showing how much it needs opening up by Picture cos tractors, we have gone from a red block to a yellow block but that's about it.... So if anyone needs a virtually brand new rope seal crankshaft or direct injection head let me know! Edit to add picture of new engine... 8 Quote Link to comment Share on other sites More sharing options...
JohnnoK Posted March 22 Share Posted March 22 (edited) Why not try the same approach as you just did but braze a fine mesh over the area to support it? Like they have done in the crotches of this combustion casing. That's a stainless mesh brazed into place to prevent cracking and blow out of the casing. edit to add: Mmmm, should have checked the date on that reply... duh!

Gazzar Posted March 22 Share Posted March 22 I wish I could braze. That's a very tidy bodge. Quote Link to comment Share on other sites More sharing options...
