Canadian Lynx Armored Car

[Andrew Rowe]

Thanks Jordan and Harry , good useful input , although I will be running standard 8 -ply military tires , but I do have a brand new set of war time tires in excellent condition , run flat , that I might put on one of the Lynx's. I don't if you picked up on it , but actually building 4 x Lynx's.
Today I had a look at the clutch slave , trying to figure the cylinder return spring length, finally I think we have a brake through and have discovered that I was using the wrong length pushrod to work this one out. New length is 11",
instead of the 7&1/2" one I had , this shorter one is for the Larger "Indian Patterned Wheeled Carrier" rear engine chassis , of which I am associated with as well, as shown in picture. Cheers from The Tank Factory.

Andrew,

Off to a great start ! Promises to be a regular read as you progress. FOUR Lynxes is quite a challenge.

Looking forward to your updates.

Thanks Peter, I have not "Officially Started" , but just tinkering away on various components , I hope my postings can compliment what you have done.
Today we can look inside the differential of the Mk2 Lynx. This runs a 40 tooth and 6 pinion axle , based on Ford 3 ton truck. The crown wheel is standard in that respect with the 6.66 ratio, however the axle housings have brackets for the big shock absorbers that are iconic to the Lynx , axle shafts are standard 16 spines as similar to Bren Carriers.

Hi Andrew, Am I correct you are going to do 4, FOUR or these at once??😮

[Andrew Rowe]

Hi Colin, YES , that is correct, I actually had a 5th , but pulled the reins back a bit as I did not have enough mechanical parts for it , chassis was a bit buggered anyway! ( 3 x MK1 & 1 x MK2 )
A few more pictures of the MK2 Diff during assembly , all parts being totally stripped and new bearings / seals applied. Second pic shows the pinion as pulled apart. In the first picture you will see the end results awaiting their final cleanup and paint. In the top of the rack you will see a MK1 Diff awaiting it's rebuild. The Mk1 is based on lighter 1 ton Ford components, but I will go into that a bit more in depth when we get to those ones, Cheers from The Tank Factory.

Today we have a look at the inside workings of the Lynx steering box. The main difference between a MK1 and Mk2 is the steering ratio. It takes 2 full turns of the steering wheel to achieve full lock in either direction on a MK1 Lynx and 1&1/2 Turns for the MK2. The bearings used are NU304E.TVP2 which is basically a paraelle roller used for the end of the sector shaft , and for the main worm shaft the Timken combination of 35-BC and 38X . Also of note it looks like they upgraded the 3 x main mount bolts from 7/16" unc to 1/2" unc.

Hi Andrew,

An interesting thread. I note the similarities between the Lynx clutch master cylinder and slave cylinder and the (Ford) M8/M20 throttle master cylinder and clutch slave cylinder.
