4500 tech question

[Anonymous Poster]

i was wondering since the 4500 and 4600 have the same size enjine, could the 4500 be tuned up to the power level of the 4600? the reason i ask is i read a post that someone had written that said the 5105 and 5205's were the same tractor and to buy the 5105 and get a good diesel mech. to tune the injectors to bring the power level up to the 5205.
i enjoy this group very much and have learned alot. i'm in the market for a 4500 or 4600 w/fel. thanx to any replies in advance.

We discussed this somewhere on another thread... maybe jplan...

I have the JD5205...it has a larger water pump, an added oil cooler, different injection pump assembly and I think a different radiator than the 5105 to dissipate 8 Engine HP difference of heat generated between the two.

I had looked quickly {not closely} and find both the JD4600 & 4700 have these differences over the 4500. {and yes the 4700 has the larger displaced engine of the three}.

Yes I agree, by "tweaking" the injecting pump to increase the fuel delivery rate will substantially increase your hp {& heat}, but other things are also done to complete this power equation to basically get rid of the extra heat generated.

thank you very much for your reply. that was very interesting. learned something. the 05's are nice tractors. wouldn't mind owning one myself.
thanx again.
