M38a1 CDN2 - Winter Project

[Wayne Hingley]

Hi David. The way you describe is the way it is mounted on my 1953 jeep. My understanding (and someone can correct me) is the CDN2's originally had these primers mounted down low to the left of the ignition switch. However that location is just in front of the driver's knee and not practical. The modification was to drill a hole and mount them up in the location you see. They did not mount them flush with the dashboard in that new location (as far as I know). Again, someone please confirm (Rob Love...?)

A poor photo below (from 1968 Operators Manual) that shows the primer in the location by the main switch, and mounted with the brass body on the driver side of the dashboard. The windshield washer fluid pump eventually took the empty position to the left of the ignition switch... Im not sure what year that modification came around. In the photo from the manual it looks like there is a plug in that hole. Perhaps the primer was located up by the main switch from the factory.

Update: I just noticed the windshield washer fluid pump shows up in the 1970 update of the Operator's Manual.

Fantastic work Wayne! Can't wait to see it in person!

...took another test drive this morning. Working much better, but not perfect yet. Still a small hesitation, and sometimes hard to start. Ill keep adjusting...

Im not getting enough (or any) vacuum to run the wipers. I may need to rebuild the pump. Unless there are any suggestions on how to improve vacuum.

A few photos from today's drive around the neighbourhood. My two boys (8 & 10 years old) absolutely love riding in the jeep!

One of the copper vacuum lines on the windshield was completely plugged with crap. Once it was cleaned out, the wipers work great. Of course I had already switched in a spare fuel/vacuum pump, as I assumed that was the issue (I need to remember to always check the easy stuff first!).

It sounds like the mudwasps. They used to often build their nests in the vent line of the Jeep wipers, rendering them useless.

The little buggers have even been attributed to airliner crashes when they have either blocked pitot tubes or relief valve vents.

That's a new one to me... it was packed full of fine dark brown powder (mud?). It was so dense that I had to use a 12" long 3/16" drill bit to auger it out. Then I could get a stiff wire in there to clean it out. I've never heard of mud wasps, but it sounds like what I had.

Unbelievable! A guy who actually drives his restoration and will go in the bush with it. No trailer queen there. Keep up the great work Wayne.
BTW, decals received, look great.

Photo above from this site shows the primer pump set up the same as yours Wayne. I suspect with the close proximity to the light switch, the two may have interfered with each other if mounted the usual way.

Great photo Rob. I had not seen it before. Also a good visual on the alternate location for the SMG and fire extinguisher.

Particularly unusual (to me) is the reverse orientation of the park brake lever (using the seat mount bolt). I have never seen that before. Was that common, and what was the reason? Was it to avoid interference with the SMG?

[rob love]

That is the only reversed one that I have seen. Certainly not an approved modification.

As to interference with the SMG, many Jeeps would have never seen an SMG in them. It was more of an armored weapon, although they were well interspersed into all units.
