Ford 7600 overhaul

[Gruffalo]

Our 1981 7600 which we've had from new needs a clutch putting in and wondering whether to have the engine overhauled whilst it's in bits. It's done 9761hrs on it's original engine and not had any major issues - Dad always insisted on new 50/50 A/F every 2 yrs and we're sure this has prevented the porous issue. What's the likely cost of reboring, fitting liners and new pistons, and head possibly skimming and new valves ? Also it could do with the cab lining on the inside by the doors. I'll try and post some pictures if I can. Thanks

2k

I have one in the shed too, just sat there. It's had a recon engine years ago and it all good and working etc. What sort of money are these fetching now? Mine's 2 wheel drive with the Q cab.

No, it's too good for a full restoration

Not sure why but I really fancy one of these. I think its because I cut my teeth on a 4600 and neighbours had 6600s. Can't think what I would use it for either + I don't think they were actually much good, but I think they look smart.

5 or 6k I'd say, not many left now

The 6600 is still there. Make him an offer[emoji23]

hi Gruffalo you are in same situation as me the only difference is that your tractor is 7600 and mine is1960 dexta with clutch failure and worn out engine , but I will overhaul engine myself as I used to work at tractor dealer back in 1970's I am in middle of overhauling engine in TEF 20 diesel for retired farmer and I go through everything in fine detail to make sure job is done properly

Ours has been more than 'much good'

Good. I'm glad it was a good machine for you. Restore it.

9761hrs - it's barely run in
Seriously though, does the engine need doing? Is it breathing heavily? If it's not I would leave it alone - we've had 6700's, 7700's and 7710's do well over 10,000hrs on the original engines - as you say, 50/50 A/F and on the dot oil changes were the key with those engines.
While you're doing the clutch, if it's done a lot of PTO work, I'd put a new ipto hub in the flywheel (you can always put the ipto shaft in later - saves splitting it again to do it in the future).

They all breath heavily, even when new

Not a heavy as they do at 14 or 15,000.

Yup mine has since new, esp when given a bit of work, ours has been a very reliable machine despite trying to kill it on a 3.5m power harrow that it seemed to live on for it's early years. The spool valves were the only disappointment, leaking but then thats a Ford/New Holland thing, my T6090's valves leak slightly too. Progress for you

Short motor?
That’s what we used to do with ford diggers quick turn around.

If it has the original smooth block won't you devalue it by bunging in a new type motor?

Nail on head.
