Knackered Tractor

[gensetsteve]

What caused the crack, frozen block or something else ?

What about brazing it???

 

I've brazed cast in the past with good results.

 

Brazing wouldn't hold up to the stress that the block would be under. Good for rads not so good for blocks.

If its just the water jacket what are the stresses???

 

Most moden engines are alloy, so the stresses can't be that great.

 

Many steam boilers are brazed and they has some serious pressure.

Just found out my tractors knackered. The Block has a 4" crack in it:( the tractor is an IMT, copy of a massy 135.

Just gotta weigh up what to do, the mechanic says we could do a temp fix with epoxy resin this would be cheap but no guarantee how long it will last, next is the option of a second hand block if we can get one to fit, it would then also need piston liners and etc and work doing to the head. Ideally I would get another tractor, a 4wd with loader.

Ohh well, keep calm and carry on:)

HI HODGE sorry about your tractors head but I've talk to mate who worked very large plant in the middle east he said the think is cast iron repair metal switch its very good look it up on the net mate all the best with it jon

I araldited a 135 4 cylinder that had frost damaged at one of the pedestals that the clamp for the injector bore on, 1972 and it was still ok when it got exported to Pakistan some years later.

 

Subsequently I used a local metal stitcher on a Holder gearbox, in those days (1986ish) he charged £10/inch of crack.

 

I see there are several firms offering the service via google.

 

The technique is to clean the crack and pull it together, or indeed insert a new piece. Then a series of pairs of holes are drilled either side of the crack, with a slot machined between them. Into this a tapered dumbbell link of nickel is hammered, these progressively bridge the crak. To make it leak proof overlapping screws are threaded into the line of the crack and sealed in with loctite.

Metal stitching is what to look up:thumbup:

I have seen bulldozer blocks that have been stitched back together with grub screws threaded along the line of the crack then more in between to completely seal the joint, a run of weld was then placed along the top and ground of .When painted the repair was invisible, you may have to strip the engine depending on crack location

Model boilers, perhaps. Not real ones!

 

Canal Navvy is right, if you want the crack repaired, metal stitching is the only effective way to go.

HI MATE metal stitching is the best thing to use last night out with a mate who had it done on very large plant in the middle east i do no cost jon

I have a dexta that i used liquid metal on , filled a half inch frost hole in then stuck a patch of sheet over it

That was 6 years ago it works hard splitting around 600 tonnes of logs a year without a problem
