Hello everyone!
My first post on here having recently bought a YM1700 tractor which I am very pleased with.
The tractor runs very well, in fact I'm surprised what good condition it is in for its age.
There is a slight water leak from the engine and whilst having a good look around for the source of it I came across '2TR16' cast into the top of the cylinder head. However, the engine is definitely a 2TR17 as the plate with all the details is still atached on the left hand side. My question is does it matter that the head appears to have been changed for one from a lesser powered engine? I can't help thinking that there must be sufficient differences between a 2TR16 head and a 2TR17 head to have made it necessary to make two different heads in the first place, rather than just sharing one which would have been much cheaper I guess.
Despite the different head, the engine does seem to run very well, although I suspect that it has been badly overheated in the past which is presumably why the head was changed.
I eventually found that the leak is coming from the square metal plate on the rear of the cylinder head and I plan to remove it, make a new gasket and re-seal it to hopefully stop the leak. Any advice on sealing this?
I'm very impressed with this website and it has already been very helpful in explaining the cooling system and I now know to make sure that the antifreeze mix is not too strong - thanks!
No doubt more questions in the coming weeks.
Thanks for any advice!
