Fiat 70CI. Repairs, modifications and stories.
I can't help with this one. Hopefully some one else will be able to, but however it resolves, please post the solution to help the next person in the same dilemma. -

Fiat 70CI. Repairs, modifications and stories.
I think you're correct. A look at the South Burnett web site brought up this: "In the late 1960’s the 70CI models in Australia had a name change to AT7 (Angle Tilt). Apart from the upgraded track rollers and grease pump up and track adjusters as against spanner adjustment on the 70CI, and... -

Fiat 70CI. Repairs, modifications and stories.
I have two manuals and both are for dry clutch. I have a vague recollection of talking to someone who had a machine with a wet clutch but that's about it. Be interesting to put together a spread sheet of all the different models and what varies between them. Tricky though. My dozer was assembled... -

Fiat 70CI. Repairs, modifications and stories.
Glad to hear it all looks OK. Sounds as though it's settling down. There's a whole bunch of plates making up the clutch pack. When you pull the lever, you take the pressure off the pack and allow it to slip. Much the same as a car clutch, but with more plates. As the pack gets thinner, due to... -

Fiat 70CI. Repairs, modifications and stories.
I had a problem the second time I did my clutches in that the centre clutch hub was sitting too far onto the shaft. It's a taper fit but you do it up very tight. I suspect that over the years the hub has incrementally stretched. The issue was that when the clutch released, it was possible for... -

Jamming a screw driver in doesn't sound right! There's a pair of nuts that adjust the lever. Loosen off the outer nut. When the cam is against the follower, there should be 1 mm clearance from the inner nut to the lever. This translates to about 50 mm free travel at the lever hand grip. This... -

Fiat 70CI. Repairs, modifications and stories.
The clutch disconnects the track. On easy going mine will sort of head towards the left, if the left clutch is disengaged. Down hill it'll head to the right. If it's pushing a load on the right side of the blade, it'll most likely sit and pathetically spin the RH track. I find for definite and... -

Fiat 70CI. Repairs, modifications and stories.
My levers pull pretty much as far back as they'll go. If they're not hitting the seat, or ruining your chances of having a son to pass the machine on to, I wouldn't stress. The lever action should be effortless. I had an issue with mine, that every time I left it a while, the power assist didn't... -

Did the power assist on the steering lever work as it should? -

Fiat 70CI. Repairs, modifications and stories.
I took my whole ripper assembly off, dumped it in a trailer and sent it off for someone with a seriously large welder to fix up the various cracks. Bit of a bonus from the job as I wouldn't have taken it off just to be welded. I'd have done it myself in situ. -

Fiat 70CI. Repairs, modifications and stories.
Always interesting to see how others tackle these PIA tasks. I had limited facilities so put the blade on a length of steel for easy sliding and then jacked the grousers with a hi-lift jack. Lifting it up and using a ratchet strap would have to be easier! -

Fiat 70CI. Repairs, modifications and stories.
To be honest, I'm buggered if I can remember. I'm thinking the gear stick sits on a little stand and you undo a few bolts and lift the assembly off? I'm trying to find some images from when I was last in there but am not having any immediate success. I'm pretty sure the top cover comes off as a... -

LOL; so it's not just me! Same problem. F'ing great lump of steel across the back. Now replaced with 75 x 12 angle, bolted into place. I feel your pain! -

See your point. If you have the time, having a look is probably wise. Give you an idea of where you're at with the rest of the transmission. Chances are, you'll be replacing the booster cylinders, at the very least. -

If the clutches are not slipping, I wouldn't be rushing to pull things apart. Check the release levers are doing their thing, may well need adjustment. If the levers are releasing the clutches correctly even a rusted clutch pack should break loose under torque. Once loose, they'll soon polish... -

Fiat 70CI. Repairs, modifications and stories.
I recently replaced a broken track spring. Mine are tensioned via grease pressure. I took images and intended to do a write-up but have been struggling for time. To do mine, I had to break the track. If you are also doing steering clutches, breaking the track makes that job easier. To break the... -

70CI root rake
Thanks for that Metalman. It's a nice neat job. I'm looking at longer tynes and tighter spacing. Reason being that the main use will be pushing up sticks and rubbish, hopefully without dirt, and ripping out clumps of blade grass and bracken. Interested to know your thoughts on this plan. -

70CI root rake
Thanks for the replies. The 6mm is due to that being the heaviest section 125 x 75 is readily available in. My concern is exactly as redneckracin puts it, one tine hooking. My concern is not so much that the RHS won't take it, but that the attachment for the tine will tear off. I'm giving much... -

70CI root rake
Just starting a little project to fit a root rake to the blade of my trusty Fiat 70CI. Thought it'd be fun to share this. Basic situation is a 70 hp dozer. About 8 acres of ground to clear. Many clumps of sag which is a type of clumpy blade grass found in Tasmania. A good size plant can stop the... -

BTW. Thanks for the images JimBob. Interesting to see the stripped machine. I have to say I'm curious about the wear on your tracks. My grousers are no better than yours but they are worn straight, whereas yours curve off to the sides. I also note that your track plates appear to be worn thin on...
