Repair of frost damage

[Great War truck]

This early Leyland engine has suffered some frost damage. In your collective opinion, do you think it is repairable?

 

 

Thanks

Hi Tim,

 

It would hlep if you had the broken pieces or most of them. I has reminded me of a training course I was on once, when with MoD. It was run by Belzona, which is a manufacturer of chemical repair solutions and used extensively in industry. Do not compare this with metal putty or plastic metal. The chap showed photos of some examples of repair and related how an owner of a vintage tractor, contacted the company to see if their product would work on a frost damaged engine ( from the photos, it looked to be a Fordson Standard block). He was told to clean it up and an engineer would come out.......when he arrived, the guy had cleaned it up..by breaking out all the cracked parts and cleaning them, leaving a gaping hole similar to your photo. The job was a lot more complex now, but it was all pieced together using Belzona and never leaked.

 

So in answer to your question, it could be possible........at least it is not a pressurized cooling system so that helps.

When in doubt, ask Richard :idea:

Wonderful answer. I thought that the reply would be a simple "not possible".

 

Now, i am under the impression that some (possibly all) of the missing pieces have been lost. Will the repair still be possible, and what can be done about the missing parts?

 

Many thanks

Hi Tim,

 

Thought it would be unlikely that the broken bits were still around. I know that if it was me, I would look at fabricating a replacement out shell for water jacket, cleaning up the edges of the broken cylinder so that it fitted snugly, the stitching in. I recollect an AEC 760 block having thrown a rod, we had it sent to a specialist cast iron block repairer called Barrimore (spelling?), after they had welded in a section of cast iron, the outside of the block was leaded and with a coat of paint you would not know it had been repaired. It is worth talking around to some of the old established companies who specialise in this work to see what methods are prefered.

I had severe damage on a prop for Horatia and took it to a small company who pronounced it scrap.The reason was a previous bigger co had repaired it using the wrong material setting up a reaction.They reshaped the prop and built it up with epoxy so it could be used to make a mould to cast a new one.This they did then machined it to shape,these people were artists.The prop was 24x24 so reasonably big and the bill was a grand,I think if its that inportant to you there are people out there who still work mirricles.It just takes time to track them down.If its the last one left you dont have a choice.cheers john.

There is a large amount of debate on whether to cold stitch or weld repairs. I imagine the answer boils down to cost and application.

 

Cast Iron Welding Services are specialists in, er, cast iron welding and have done lots of work for vintage car owners over the years. More info, and some pics, here: http://www.castironwelding.co.uk/

BELZONA! Now that was a wake-up call, Richard.

 

We used it up until 18 years ago for all manner of "super bodges" and I can testify to its ability to do the impossible. First application was to rebuild a badly worn torque converter input shaft as a tempoary fix until a full rebuild, but that was going 10 years later when the loader was sold. It had a very short shelf life, so unless you were a regular user most got wasted, and you couldn't trust old stock. www.belzona.co.uk Still going strong.

 

Never tried complex repair stuff like the Leyland block, but why not? Just need a material with a similar expansion coefficient to C/Iron and you have yourself a chinese vase and the right glue.....

 

Aplogies to Tim, I thought this was a ploy to get opinions before you posted an "after" picture, knowing the sort of work you are capable of!

 

If the photos in some adverts are to be believed, Runflat, there are some highly skilled welders out there who would relish the challenge!

Tim bet me to the mark in posting this picture. I sent it to his brother originally seeking an opinion as to repairability considering the tasks they have undertaken. I'm prepared to spend time rebuilding this, shaping steel sections to allow them to fit, and if to be taped and screwed in place I'll undertake the work. Concern is there regards expansion rates between steel and cast and welding techniques if a decision is made to weld. Checking out suitability of firms to take on the welding.

Will check as to the availability of Belzona here in NZ. It sound like a useful product.

We had another 36 hp engine along with the rest of the truck made available, however before we could collect it the scrap price rose and its now gone to China.

That made me laugh, as you are quite right as that is exactly the sort of thing i might do.

 

This thread just goes to show what a marvellous pool of knowledge we have on here. So many thanks for everybodys posting.

 

Hopefully Doug will be able to get his engine fixed and other readers will see what can be done.

 

Our Autocar engine suffered extensive frost damage at some stage and the French owner had soldered it all back together. It was a marvellous piece of work and probably done in the 1920's. I will see if i can find a photo of his handiwork.

 

Thanks all
