m806 arvl info needed

[Tyson Eich]

Hi Guys im looking to see if anyone has any information on the m806 arvl
like how many pounds the winch can pull and and fluid capacity or any info would be great. there were only a few in Canadian service and info is basically not available for these units.

First I ever heard of M806 ARVLs in Canada. The M113A2 Recovery vehicle, light, was still referred to under the M113A2 name.

I just checked our tech library, and we have the parts manuals for the ARVLs.

I note the winch parts are the same as that used on the M577 ARV. I'll research a bit further. I'm pretty sure I saw the data summary here somewhere, but my tech library is a collection from several sources, and a lot of things like data summaries were not put away by their respective CFTO numbers.

Found the data summary for the ARVL. It is a Pacific Car and Foundry model P30 (modified) 20,000 pound hydraulic winch.

The ARVL was the very first M113 FOV I had to drive on the highway. It was an end ex, and for some reason I got thrown into the pig. The heater flooded out, so no heat, and the thing was all over the road as we crossed over the swamp heading towards Douglas. The infantry carriers we were with scooted off into the distance and we caught up to them at the coffee stop.

I have no fond recollections of that trip.

I called it a m806 as thats about the only carrier that I can find any information about and seems to have only been used by Australia and Canada. These seem to be a rare beast and there is virtually no information or really any photos of them in Canadian use. 20000Lbs seems like a really low powered winch when your thinking about pulling forces on a stuck carrier in a bog even once double lined.

Don't mix rolling resistance with the weight of the vehicle being pulled. The ARVL was meant to give units with M113s the ability to recover them. A carrier is only 21,000 pounds, give or take, and depending on conditions, the winch is only dealing with a fraction of that. So once you go to 2 to 1, or even 3 to 1 on the cable setup, you have plenty of pull.



The majority of the NSNs in the manual for the ARV are US based, so the design may well be adapted from some American variant like the M809.



Is there any specific information you need on them?

Is there any information about fluid capasity of the hydraulics and pump info or the plumbing in general

The ARVL is somewhat of a rare bird although as Rob as stated there is information available on this vehicle type. My count tells me that there were 37 in the CF and originally the ARVL was based on the M113A1 although beginning in the late-1980s these were upgraded to M113A2 with two different ECCs for this vehicle type. My records tell me that they were all disposed of in the 2000s with the last one in 2012. Which one do you have access to?

Here are a few images from my collection.

We have one at the museum in calgary here and we were looking for information about it because it's kinda rare no one really knows anything about it

[rob love]

They fall under the C-30-672 series of CFTOs in case anybody wants to look them up. For the M113A1 they will be uinder the C30-572 series of pubs. I believe I have an old index of CFTOs, which should list all the relevant publications under those series. The two parts manuals we have at our museum cover the winch and hydraulics, the rear door with the much larger tow hitch, and the small crane on top. Otherwise, it's pretty much just another M113.

Hydraulic tank is 30 gallons. Originally the pump was belt driven...there was a mod for a much larger direct drive hydraulic pump which will extend through the lower engine cover. This is detailed in an installation instruction I have here, and is also likely reflected in the parts manual. It would appear the earlier setup had the ramp also running off the winch hydraulics. This installation returned the ramp to a separate installation.
