1944 C-15A-Wire-5 Restoration

Nice work Robert. Im curious how loud it is with the generators running and all the compartments closed up?

[Robert Bergeron]

Thanks for your nice words . It’s noisy Wayne ! I made rubber pads for the supports so that reduces the noise considerably . The fact that they both exhaust outside helps also . The original had a muffler under the body so i installed one on the 1 inch line . It is bearable . I wish i knew how to post a video here it would be neat to let you hear it .

I ain't going rubber pads on my HUW chorehorse. It's metal on metal crankin' out the decibels all the way baby!!!

If you have ever been to an antique engine collector how you would see civilian Chore Horse running and fitted with a 20 foot section of flex pipe fitted with a cast iron ball type sound breaker.....which they usually buried in a few inches of loose dirt.

The noise level becomes quite subdued and muffled.

Any reason why the military would not have used a similar contraption????

The chorehorses did come with that flex line for burying into the dirt. I think you just transferred the regular muffler over to the flexpipe, but won't say for sure. It's been a lot of years since I worked with them.
It made them very very quiet.

Reference picture of the correct Canadian Chorehorse for the 2K1 box. When operated on the move from the generator compartment they are noisy because you can’t obviously bury the flex exhaust in the ground to damper the noise . The flex hose is seen in the illustration with the small pancake muffler for ground station use when you pull it out of the truck . I was fortunate enough to find two of them in good working order . Both were made in 1943 and are almost identical except for a few minor details , probably replacement parts . Both have their protective covers . Much less common than the later Post-war 30 Volts conversions . British models had protective cages like the Post-war version .

[Robert Bergeron]

Took these two identical parts off my second 2K1 box . The were riveted in place . They were on the right lower corner of the rear generator compartment external doors . The doors are in two sections and they move up to let fresh air in when the generators are running . They are both identical and marked : Pat 1936 other patents pending Canada . At the bottom of each door centered is a handle to help move it up and down . The handle abuts to the top of the opening . What is the function of this part ? The scew on top is functional and comes out when turned counterclockwise . ?

.....muffler/pipe readily available on Ebay from $50 to $75 + USD....... cast iron ball type or flatter disc shape like the military. Ear plugs 0.50 cents.

Cheers

The BSA version that I have (still crated) comes with flex hose and muffler, but as far as I'm aware they were only ever used with the flex hose in the field: drag it away from the vehicle (downwind), extend and bury the hose, then recharge the spare set of batteries (do NOT float-charge the WS19 battery).

Unfortunately my crate was opened and is missing the tool/spares box with the manuals, cables, etc. (I have most of the spanners and am looking for the rest of the bits.)

If running them in the vehicle I'd fit a couple of carbon monoxide detectors - one in the generator compartment, and the other near the operator position, just to be on the safe side.

That begs the question, was there a special exhaust pipe issued with wireless trucks to meet the specific need for in vehicle operation? The HUW has a hole in the bottom of the generator cabinet that attaches to a fixed steel tube exiting out the vehicle floor. There must have been a 'quick release' pipe to go from the generator to the connection. Like most wireless trucks, they set it up so the generator (along with the wireless set and batteries etc.) could be quickly removed to work remotely. That's when the flexible exhaust pipe and muffler would have been employed.
