This is my PPT project. First let me relate what little info I have concerning the manufacturing history of PasseParTout's. PPT's were made at three different locations. Valcartier made them in Courcellette, Quebec first. I'm not sure when exactly it moved from there but am sure it was still being made there in November 1970. They then moved to Edmonton, Alberta and were made by I believe, Valquentin Industries. Again not sure of the time period. Lastly they were manufactured by Twin Bay Industries in Elk Rapids Michigan where mine was made. I know they went out of production there sometime in the mid 80's.

I have service and parts manuals for the later models, which I can provide copies of to anyone who wants them for $40 for the set, which includes shipping. They may also be helpful to owners of earlier models. If anyone is interested just contact me

The first picture you see on the left is how it looked when I first acquired it. It was originally all yellow but the previous owner had painted it black and white. A local county had been the first owners and they apparently used it for spraying mosquitoes in local swamps. It was purchased at auction along with its twin by the gentleman from whom I purchased it.

I sanded down the fiberglass hood and repainted it to its original yellow color. I also repaired the vents and replaced the gauges. It's powered by a 16 HP Onan engine driving a snowmobile type variable belt drive connected to a gear transmission. The transmission has 2 forward speeds and one reverse and I was having trouble keeping it in gear. I removed the whole engine/drive train assembly and dismantled the transmission. I found a couple bad bearings and the linkage way out of adjustment. Unfortunately I didn't get any pictures of this part of the project but repairing these items cured the problems.

I played around with it for the rest of the summer and found it was an excellent runner. It was much better at traversing downed trees and especially brush piles and heavy brush than any of my other ATV's. It did however, not seem able to climb or descend as steep an incline as my MAX IV. At least it was very unsettling to do so.

One of the problems facing me was the poor condition of the front and rear track rollers and a few missing or broken track teeth. You can see in the one photo that the roller on the right of the drive cog is completely missing. The others are cracked, split and some half gone. They are all hollow plastic and don't seem to have held up too well. I came up with some solid plastic wheels from Grainger's that I hope will work out as replacements. You can see them on the axles before I reinstalled them. The track teeth are simply screwed onto the track belt. They were original a hollow plastic and supposedly designed to break away should something become severely jammed in the cogs. I made some out of a large plank of UHMW plastic I acquired from Machinists Materials. They seem to have turned out well and appear tougher than the originals. I am only replacing them as need be.

This pretty much puts the PPT in good operating condition. Eventually I will sandblast and paint the main chassis of the machine but for now will stop here and concentrate on some of my other projects.
