|
|
Hello everyone,
Please see the attached photos.
I have a 2332cc bubble top Aluminum case. I'm using OG cylinder tins and doghouse fan shroud.
In the one photo you can see the fan shroud touches the engine block.
For those of you also running a doghouse fan shroud with a bubble top case, did you have to trim the areas I've circled in red?
If trimming the shroud is a must, anyone have an up close photo or template you used?
thank you
Ted

| Grab the tin snips and start trimming. With tge shrouds sitting on the case you can see where it hits. Your also gonna have to put spacers or cut and weld the ends where the cylinder tin bolts on. |

I think its easiest to bolt up the alternator to the shroud, and start fitting the shroud without the cylinder tins. Once the alternator is down in its stand, and sitting square, then add one side cylinder tin, and make it fit, then do the last side. You will also need to rework the pulley, and the sled tins.

Don't you have a classroom full of impressionable minds to educate? Lol!
Ted, Like Brad stated, get the tin snips out and start trimming. I didn't make any template for the massive amount of cooling shroud trimming and cylinder tin widening on my 2276.
The images below are what I went through to get my tins to fit a very wide engine that I built a year and a half ago.
Cylinder tin and fan shroud mock up.
I needed to trim the FS about 8mm to get the generator aligned with the crank pulley and sitting on the filler stand correctly.
The FS sitting ontop of the bubble top case.
I made up the difference in the short cylinder tins by adding around 10mm strips of sheet metal to seal the tins against the bottom of the cylinder and the case. The pic is not pretty but the final product fit well and keeps the cylinders cool (er).
Then I had to deal with the massive gap between the cylinder tins and the FS.
The sides of the FS were sliced and widened to meet the cylinder tin fastener holes.
The test fit.
Like I said, it's not pretty, but it is serviceable. I welded inn some sheet metal strip oi the inside of the FS and then used some body filler to smooth things out.
Pay no attention to the condition of my garage. It was a busy time in the middle of winter.
This one is just for Steve Marriot!

Wow! 67 that is some impressive surgery you did there .
I did not think of what you and Brian said about starting with the alt/gen to get that fitting before fiddling with the cylinder tins. I'll give that a go and see how far off the shroud is from allowing the alternator to lay flat in the stand.
I'll try to snap a photo or three once I get it to my liking.
thank you and everyone else for replying. I appreciate all of ya!

Hey Ted, I try to share my experiences when these turn into puzzles.
One thing I didn't, or forgot to mention above is, You may have to extend the FS flanges where they intersect with the cylinder tins.
It seems like a strange thing to do. But I found that after trimming the FS where it contacts the AL case. I had a gap at the flanges into the cylinder tins.
Fun times.
Definitely get the gen/alt sorted first. I didn't and it was a bit of a set back once I went to fit the gen on the engine above. _________________ I have learned over the years.

Another thing, as the memories/nightmares flood back to me from my build.
Think about what carb linkage your gonna use.
I wanted to use a CSP center pull linkage that I had on hand for my 48IDA carbs.
The CSP center pivot will not work on an AL case, without modifying it, extensively.
I ended up using a VS center pull linkage that attaches to the oil fill/gen stand base. Not the ideal setup for an engine that was built for racing.
Recently Alstrup mentioned that a Hex bar linkage would be a better choice for carb linkage.
YMMV!  _________________ I have learned over the years.

Oh, definitely, but I need some escapism here and there - especially in the week and a half before winter break . . .

Thanks for the great suggestions. For carb linkage I purchased the CB hexbar kit along with my IDAs. Hopefully that will work well.
Lots of odds and ends to button up. Besides fitting the tins, I still need a spark box and ignition coil. For the carbs I've also got to work out the fuel system. I want to bench run this engine when its break in time but am not sure yet how to plumb the carb fuel lines. Maybe a -6 T connection with the feed end hooked to a good electric pump and that fed from a gas can?

When I built my test stand I used a fuel tank off a riding mower mounted up high so it would gravity feed. You could use some sort of improvised stand and a temporary tank like motorcycle mechanics use. These have a built in petcock for shutting off the fuel flow. Gravity feed is the ultimate KISS fuel system. |

| Silly little question, street rod, putter, could one remove shrouds? And run with out, maybe a pusher fan on lid to pull heat from engine? |

Simple answer... NO.
Time has proven that the original German engineers were pretty smart. _________________ Glenn
