Hello men
an update of the restoration.
The past week I took the engine apart...bad news!
When honing the second cylinder bore it turned out there was a major damage all around the bore.
There must have been water in the second cylinder when the engine was stored resulting in a deep rusty indentation.
There was allso scoring visible on the shell bearings of the cranckshaft, as wel on the main bearings as on the bearings of the connecting rods.
I guess the engine has been neglected in the past and the oil has become too old and dirty and that's the result.
It turned out that 3 of the 4 pistons were the same and one was different...
The first piston has no T -slot, the other 3 have a T-slot as normal in these engines. I think that the first piston was heavier than the other 3. It must have been changed sometime in the past.
There was also a lot of carbon built-up in the heat expanding slot of the pistons. The first groove of each piston is ment to stay empty to allow the piston to expand when heating up so there's no piston ring in it.
One piston was cleaned, the others were left as I found them.
So, I have a bad engine...
I don't want to get the engine rebored and the cranckshaft to be regrinded because that's waiting and asking and getting promises when it will be ready and then new promises and more waiting...
NO, I'm sick and tired of hearing false promises about when the work will be done or when the parts will be available.
Don't get me wrong, I don't mind waiting for a job to be done but when the time comes, I expect it to be ready, I've heard enough excuses why the work isn't done.
But I have a solution!
Next week I'll get a refurbished engine block (new cylinder liners, standard bore size) and a refurbished cranckshaft with new bearings, new valves (valve seats cut), new valve stem guides, new pistons and piston rings.
It will cost me several thousands of Euros but you know what they say: time is money!
I won't have to wait and I'll be able to continue rebuilding the engine.
I'll be able to put a "new" engine in the jeep in order to ride it without troubles...at least that's what I'm hoping for.
More news to come soon!
