I recently had an engine built by McMark and I am now starting reassembly.

I figured that this was a good time to have some parts powder coated and hardware zinc plated.

They turned out pretty good so I thought that i would share, here is the result of a couple of pieces.

Wow! That is purdy!

I would suggest you make sure the fan is balanced now that its all back together.

Looking very nice! If it runs as nice as it looks, and it should having McMark rebuild it, you are going to be one happy TEENER!

Thanks for the tip on the fan balance. How is a good way to test the balance of the fan?

Is it a full rebuild? If so, you can get the whole rotating assembly balanced -- crank with gears, flywheel, pp, crank, fan. (I think that's everything.). Also a good idea to get your rods balanced end to end and matched to each other, as well as match the pistons. I think shooting for .5g between the heaviest and lightest is what you want.

Any competent machine shop can balance your stuff.

I am new to engine building but that's what I am having done to my parts...others with experience may chime in.

Looks bad to me.
Compressed when cold. Expanded when hot. That looks expanded.

you shouldn't be able to slip much between those bellows when it is cold.

Living in Clovis you ought to just get rid of it. Do you really need heat?

I made the mistake of taking a fan apart to blast and paint without noting the original orientation. The machine shop had to drill a half-dozen extra holes in the back side of the fan to balance it

Lesson learned - I'll ALWAYS stamp some markings on the fan and pulley prior to dis-assembly to assure properly balanced reassembly

Looks like the fan is heading to the local machine shop for a balance check.


Any Ideas where one can find a usable thermostat, they are pretty much NLA it seems.

If the shop says it's out and needs to be drilled, have them mark where the 'heavy' side is. Take it apart and reassemble with the small weight (on the inside of the front of the pulley lip) on the 'light' side and recheck the balance ... they may not have to drill it.

There is a guy on the Samba selling new ones: http://www.thesamba.com/vw/classifieds/detail.php?id=1036746

Great tips all

How close is adequate when it comes to balancing the fan?

Posted by: Porschef Jul 30 2012, 06:10 PM

Kelly,

It is purdy, put it back together and enjoy.

I like my attention ho 914 much more than I ever did the very reliable 75 911s I had...never a single problem with the 2.7... Drove it cross country in 93, and the only hiccup was an almost imperceptible hesitation as I was crossing Summit pass in CO...never gave me a problem....

Making sure the pulley part runs true as well.

Posted by: echocanyons Jul 30 2012, 09:14 PM

I had the fan balanced as a whole, it didn't come out perfect but they didn't have to drill it. How much out of balance is too much?

Also, what marks should I make before plugging this thing back on the engine?


At this point I'm pretty much dying to get my daily driver back on the road.

Posted by: euro911 Jul 30 2012, 10:03 PM

How far out of balance did the shop tell you it was? If they didn't drill it, maybe it wasn't too far out

TDC and either 7.5° (1.8L), or 27° BTDC (1.7 & 2.0L).

Here's a good tech article on Pelican: http://www.pelicanparts.com/techarticles/914_timing/914_timing.htm

Although not my preferred vendor (or 2nd, 3rd), AA has a new type of thermostat that is supposed to work. Their part # : R021119159A, and last I checked it was $74.50. Although this week in the Valley we sure don't need a thermostat as was pointed out above.

All looks great by the way.

I went ahead and ordered a thermostat on thesamba, probably not necessary but hopefully it helps a bit with warm-ups.

The fan was a couple of grams off, the shop did not recommend to drill it.

I ended up marking TDC and the hard mark on the fan.

It's coming together.
