Vehicles originally painted to contract spec at GM plant - solid flat olive drab finish.

Not olive drab; Khaki was the British colour, Olive Drab was the US colour.

Well the students tried to crank the engine over and found out that the flywheel is cracked. Now they have removed the transmission and started working on the bell casing. Pain in the backside with some of the bolts in the actual casing itself. One looks like it might be stripped.

On a positive note the new master cylinder was reattached and the new lines were installed and now the brakes work.

I've also attached two new pics of the fuel line switch

Hi Joel; Nice to see kids working at preserving history. If you can't get that fuel valve to work properly PM me and I'll see if I can't find you a NOS replacement from the collection here. Might even have a flywheel if yours is damaged....Bob

Well the students finall removed the flywheel...holy crap...what a pain to remove. First they students removed the transmission (one student thought he could lift the whole thing himself, he tried but quickly yelled for help). Then they had to remove the clutch plate and then the flywheel, all with the bell casing on because you can't remove the bell casing until everything is out of it first...ahhhhh

We are trying to see if the flywheel can be replaced but we don't know yet. The students finished off the major body work so that it can be sandblasted, then returned so we can get it painted. Two of the students can not wait for it to get back so that they can complete the body work.

Hi Joel

Didn't really follow the problem with the flywheel, was it loose, flywheel cracked, or the ring gear damaged?

Cheers Phil

Great photos, hope all the students are enjoying the project, most of us reading about the process are wishing we could have a project like that in school.

[Joel Culliford]

Ring gear is cracked, We are hoping the 2nd CMP has one or that Youngs Automotive can find a replacement, so far they haven't let us down, they have been awesome.

Great work you people are doing,i put a link on face book to it on my page under Ken Hughes (in New Zealand)

Hi Joel

If all you need is a ring gear or a spare flywheel with the gear installed then I would not tear down the parts truck....... I think a lot easier to find one than to strip major components from the spare truck. I have spare flywheels here in Ottawa..... it is just that finding a large enough envelope to send it to you is a bugger !!!!

If you are desperate, I could sandwich the flywheel between two squares of plywood and forward by Grey Hound bus..... but it is heavy $$$$..... in all eventuallity you would need the clutch surface polished in a machine shop.

Hi Joel

You should be able to get the flywheel ring gear from a local parts supplier price range around $50. Checked the Chevrolet Master Parts book 1938 - 1951 it list all flywheel ring gear ALL 38-51 as being part # 3835306 may actually run later than 1951 as I remember the key to knowing which is the number of teeth.

Tried looking on NAPA Canada's web site and found BKP 6003002 as being the part number with this as description:

Line code BKP
Part number 6003002
Description Flywheel Gear
Attribute Product Features:Replacement Ring Gear On Flywheel & Flexplate Assemblies Duplicate Original Equipment In Fit & Function,# of Teeth:139,Manufacturer:Anchor Industries,Mfg Part Number:139CF,I.D.:13",O.D.:14",Width:.507",Pitch:1 0 / 12,Tooth Chamfer:Front

Obviously have the local parts guy confirm that this looks like the correct part number.

Check your tooth count, I could not find a price on line from Canada but US Napa wanted $42 US. Last time I ordered one of these it took under a week for it to come in.

Reason I mention this is that having a flywheel shipped may cost more than what the ring gear costs.

Installing is easy, heat the ring gear in an oven to 350F pick it up with a pair of clamp on pliers and it will drop right on to the flywheel.
