Canadair CL70 CFR 58-91588

Thank you for that Marc, just a very useful read in general aside from own personal interest.

So,

a request to you all. I need a quantity of small tires for this restoration.

3.40/3.00-5 is the size I am after, in black and a ribbed tread pattern like a wheel barrow is desired. They will have to be tubed I am thinking. As yet I have not taken one of the rims apart.

A two or five dollar difference makes a big difference at the end when you consider how many tires I need for the whole machine, which is 20. Right now I would like to get 10 for the rear car as that is going to be done first.

If anyone can make some suggestions please.

Any chance of a photo of the tire you are looking for?
A drawing in the repair manual suggests a profile similar to a wheelbarrow tire with circumferential rib/groove tread.
A cursory Google suggests the size is used on lawnmowers, handcarts go-karts and (ultralight?) aircraft. http://www.lawnmowertirestore.com/3-...-and-tube.html and http://www.aircraftspruce.ca/catalog...SABEgLBI_D_BwE PLy ratings and weight capacities seem to vary with most of the Google results having squarer shoulders than the manual seems to be showing.
Also, what weight capacity do you need? Google was showing a range from 380 to over 450 pounds.

[Robin Craig]

Grant,

silly me, yes a photo always helps doesn't it.

Here is something that kind of shows you. It is actually called a saw tooth pattern and has a slight side to side zig zag where as a wheelbarrow is a multi groove around a circumference.

A weight rating of 350 is way overkill.

[Robin Craig]

Grant,

the first link was very acceptable, the second one was too chunky on the side for my liking.

I assume the first one is in USD

[Grant Bowker]

Not confirmed about USD but reasonable as they are in Newburgh IN.
Another US source http://aircraftproducts.wicksaircraf...be-2/tr100-065
Several wheel assemblies, apparently not sold as tire only https://www.motionindustries.com/tax...000000%7C10+in

Carlisle seems to make tubes for that size https://www.walmart.ca/en/ip/Carlisl...RD5S245Y9R5E5J so might make the tires too but a quick look on Carlisle's site didn't find the tires....
It seems they do, as part #519016 https://simpletire.com/carlisle-3.40...5-519016-tires Several sites show the tires as not stocked but orderable....

So,

It has been a long summer with little time for me or the CL70, such is life and my work schedule and demands, it pays the bills and has perks so I can't complain.

So the CL70 has, to ensure starting at sub zero conditions an ether starting aid system. The manual makes reference to it but doesn't give any details of maker or anything r even a picture of the "capsule" that contains the ether and makes it work. It was just one of those details that I was figuring was lost in time.

Once again, life, strange as it is, taught me that there is always the chance of a gem if you get off your backside and network and use your noggin.

So I went up yesterday to Oshawa as an invited participant to the opening of the Military Vehicle Conservation Centre which is the first part of the planned building expansion program as I am a museum member, so the CL70 was far from my thoughts.

But I digress somewhat, this week saw me wasting time on the vacuum that is Facebook but with a surprising benefit when I saw a Swedish truck for sale in the UK and the detail shots of the interior.

On the dash was a familiar looking device, and questioning of the owner confirmed it was an ether cold start system. See the picture attached and the silver reservoir type affair on the dash which if you were not careful could be mistaken for say a brake master cylinder reservoir. I asked the owner if he had ever seen the capsules that went inside but he said no.
