Trying to wrap up my 2056 build off of a 1.7 case. Has anyone had an issue getting the air baffle plates to fit with the 96mm cylinders? These are the little cooling tin pieces tucked under the cylinders on both sides. The 3/4 one seems to fit, but the 1/2 piece, which I know is different, will not. The "ribs" on the piece are interfering a bit with the cooling fins on the cylinders. I'm happy to grind the tin down a bit to get it to fit, but I'm hoping this isn't an indicator that I've done something else wrong in terms of assembly.

I DID have .035" shaved off the bottom of the cylinders to get proper deck height, and I can see where that may have contributed.

I believe the baffle pieces are unique L/R but are the same across all years.

TIA

Add a photo, but I seem to recall the parts are identical from side to side.

Pretty sure they are different (different part numbers) L/R:

Baffle plate 021 119 319 ®
Baffle plate 021 119 320 (L)

I can try to get pics later.

The parts are different from side to side.

I'm guessing that shaving down the barrel is the major contributor here. I'd be tempted to pick up an extra for that side, then trim to fit. The extra one would be for when I f***ed up the first one, or for when I discovered that something else was going on so I needed an original part again.

Hate when that happens.

BTW.

I don't remember having to trim the deflector when I did the 2056. Used AA cylinders.

Or could be I just don't remember.......

Thanks fellas. I'll probably go ahead and judiciously grind the rib back so it fits.

Hopefully nothing else going on...

All the baffels are the same. They were NOT designed for 96mm barrels. You have to modify them to fit the jugs. They are an important part of the cooling system. I covered this a couple of years back.

Bend the case tabs.

This is good info. I tried to search for it on the site, but didn't come up with anything. Hopefully someone else will find it (or this thread) next time.

Some judicious snipping and sanding and I think I've got it fitting ok. I did bend the tabs as well, thanks Mark.

Engine tin is funny stuff. Between different versions of Type 4, and it being bent and flexed over the years, it seems like it's always at least a little bit of a struggle to get something on correctly, although this is the first time I've had to cut something.

As always, thanks for the shared wisdom from all.
