Shim Removal Tool Ferrari and Fiat X19

Recall seeing a thread that shims from a Volvo will work.

 

only one 2V engines

 

Fiat (128 - 127 - iscunonove - ...) uses the same shims as the 2-valve V8 ferrari: 33mms.

I haven't asked yet, but a good parts supplier perhaps can get the 29mm valve shims...


Bell, you can order your X1/9 shims at SP if you like. ;-)

 

The X1/9 motor is a SOHC and the tool works by depressing both valve buckets at the same time, with the tool between them so supported on both sides. I doubt that it would stay put when depressing a single bucket as in the 2v 308.

There's an old thread somewhere that says that the tool for the Fiat DOHC motor used in the 124 works on the 308. I've never tried it.

The Fiat SOHC and DOHC use the same shims, 33mm.

 

The Fiat 124 tool works great on 2 valve 308s. Had one for a while, but gave it to my techs since I had no further use for it. Two curved prongs pushed down on either side of the lifter and the shim popped out easily with a small screwdriver or ice pick.

 

Volvo 240 and x1/9 shims are the same

 

The Fiat SOHC cam tool for the X1/9 can be found by asking around Xweb Forums, there's guy there has started making repros and there are a fair number of originals still floating around. Midwest-Bayless and Fiatplus could probably find one for you as well. It works so well that I wouldn't waste my time looking for anything else.

(I'm looking for a Fiat DOHC tool for my 308)

 

Some thread necromancy in a worthy cause, as I just finished swapping out a 308 shim using the Fiat tools.

First, the two prong DOHC tool available in the US aftermarket will not work on a two-valve 308. It's too tall to fit under the camshaft, and the prongs are wide enough that they won't clear the bosses at #1 and #5 cylinders. It's quite possible that original Fiat tool would work, but I don't have one.

Second, and to my surprise, the one prong SOHC tool needs just a touch of grinding to work just fine on the rear bank of the 2V 308. All that is needed is to bring the height of the "fin" down a bit, and to taper the nose a bit... Both changes that will likely be helpful on the SOHC Fiat motor as well.

I'm not sure about the front bank with the engine in, as the handle may foul on the front bulkhead. If it does, well that's what welders and cutoff wheels are for.

 

I think taking the cams off and also changing the seals and O rings while in there is the best way.

 

Eric- The one I had was an OEM Fiat tool for the 124 Spider.

 

Any chance the Fiat SOHC valve tool would work on the Colombo 4-cam V12's ?

 

In the Mondial t repair manual, it states that valve shims can be removed by applying a jet of compressed air to the base of the shim. I have used this method and it works well. No need for a special tool.

 

Well, how do you depress the cam follower and hold it while you are blowing out the shim?

That's what the special tools are for, to facilitate removal, not physically removing the shim.

 

Yes, you are correct of course. Sorry about my mistake. I had my camshafts already out, so I was thinking of that scenario!

 

In that case you did it the hard and messy way.

Much easier to lift the follower out and pop the shim out with a small pointy tool.

 

Yes,the four-cam or quad-cam Colombo pre 1967

I read that this simple Fiat tool could be used although slightly altered ?? Need help to confirm though...
