Top Link casting.

[ollie989898]

Trouble is, if you get it repaired rather than replaced, will your insurers want to know if the fudger parts company next time you are taking your 6f down the road?

It's for this kind of thing it makes me savage when you can't seem to find a pin that actually fits the hole or a collection of decent lynch pins on a place. It's literally this one thing that costs 50p between you having a good day out and utter oblivion.

 

[David.]

Can you still buy those good quality locking lynch pins, Rubig perhaps was the name?
Most seem to be soft Chinesium crap from dealers stores.

Credit where it’s due- it’s one hell of a casting if it didn’t just snap off the first time you lifted it with the pin half out!

anything over 5 should be semi mounted anyway on the road imo.

There's nothing worse than a flaccid lynch pin.

My local dealer only stocks Sparex ones in a bucket, every time I buy a handful I have to lay them out on the counter and go through them one by one to make sure they actually work.

I ripped a casting out the back of a lwb t7 NH.

Insurance fully covered it.

Never found pin yet. Have had a metal detectorist look.

Be interesting to know if it was lynch pin first or just ripped out.

The bush needs to become part of the casting to replace the metal that was drilled out from around the original hole,hence the welding...

I don’t think that the bush fitted as standard to the 7400 series Fendt back end is welded in. Not noticed them being so. They just look like interference fit bushes to me, not that I’ve actually given it much thought.

 

[startinghandle]

Perhaps weld in some scaffold tube?

What is problem
The short piece of scaffold tube which I had to make diameter bigger for it to fit
Did 100% satisfactory job

Why the f**k Massey use the stupid hair clip thin lynch pin to hold the top link in place I’ll never know it’s a sh!t idea

 

[jms37]

We’ve had a few “nearly” episodes with pins. Older timers here always give out about the quality compared to older ones.

This thread has made me decide to get some decent pins.
Any suggestions?
I know this isn’t a particularly helpful tangent for the poster- so apologies!

Welding around the outside between bush and casting won’t add strength back to the body of the casting though. The only way would be line boring, welding and line boring back to size. I don’t know if that can be done on such a small hole.

unfortunately I think it is a new casting job, which is going to be horrendous.

or…. Accept the loss of that hole in the casting and use the others.

Sorry, just taking the mickey.

Similar incident on a tm150. Broke one side off at the hole. Amazingly the R-clip that had 'fallen' out landed neatly on the U guard

We welded it back on and made a heavy bracket to reinforce it and replicate the 2 top link holes that bolted on down towards the pto. No bother, but an accident investigator's wet dream.

 

[pycoed]

I wonder whether a local engineering firm could drill it oversize and bush it back to original size?

I would have thought that , but watch Cutting Edge Engineering on Youtube who does a lot of high load hole repairs. He always welds & re-bores, never removing metal & rebushing. I don't know how much meat is around the damaged hole in question, but it seems a sounder plan to me?

 

[David.]

The forces involved in anchoring a top link that is carrying a heavy mounted plough, even before shock loads from bouncing on rough ground are considered, must be akin to those holding an airliner engine in place.
Bearing in mind that this is a casting, how confident are we that a weld repair is going to be strong enough?

To be fair the fact the casting has miss shaped and not broken I'd be fairly confident someone who knows what they are doing could weld it and re bore it. Certainly they'll be able to tell you whether it's even doable.

If you call the insurance, they could well cover it.
If you repair it and it breaks later on in life, almost certain they won't cover it.

The Deere design is best where the hole for the linch pin is always vertical.

I suppose its good, but sometimes annoys me a bit insurance would rather replace whole thing and not repair it.

I had a cracked fibreglass tractor bonnet. I know a guy that would have made decent job of repairing it. They refused and insisted on replacing whole bonnet.

In that you’re correct as a bonnet it’s essentially cosmetic.

Always recall a story a local at engineer told me from the days when insurance companies actually did repair stuff.
Tractor got hit by a car on rear wheel. Wrecked wheel and rear trumpet. Old tractor so insurance paid for a complete rear quarter of a breaker.
The new second hand parts fitted and ran fine for 6 months. Turns out the new half shaft was warped and killed the diff and new trumpet housing.
Customer back to square one. Insurance company don’t want to know, they’ve paid out.
It’sa horrible can of worms and you can quite see why insurance take the stand that they now do
