Lynx II, hull # 4225

Guys,

Another quiet day in the county. I hope the 'light at the end of the tunnel' is not an express freight train, and that life will return to normal.

Guys,

Our oldest grandson, Chase, is visiting and of course we had to take the Lynx for a spin. He is now the third generation of our family to take the Lynx for a drive.

Guys,

Had a great weekend at the Aquino show at the Ontario Tank Museum, networking with the folks from the OMVA and participating in some of the field events.
Found that I still have an issue with a front end shimmy at speed over rough ground.
This took a back seat when I heard a disturbing sound when parking the Lynx at home. Poking around I found that the double drive pulley that is bolted to the end of the crankshaft had come loose and allowed the fan blades to brush up against the radiator. Fortunately no damage to the radiator other than removing some paint.

Now to find a better way to secure the ratchet bolt.

They didn't have it back then, but we have it now: Loctite.

Dear Peter,

Despite being at the same event you and I have not talked since.

Watching you in the arena while we were waiting to come in, the death wobble in the front end was only too visible to myself both times you came around. I can only imagine what it was like to handle. I wondered if tire pressures and or the tire size itself or construction had any part to play.

I ask this as the Supacat ATMP tends to be driven too fast off road by users. There is no suspension, so the tires give a bounce which can be violent if the right speed is achieved, operators have to be mindful of that.

I agree with Rob Love, Loctite, I use that $%^& on everything (appropriate strengths of course)

I use the same 1050x16 tires and every now and then I get that wobble. Then it goes away. Haven’t really found out why but the only thing that was different is that it was soon after I used a tire shine to clean up the tires. Maybe sun on one side. Still a mystery to me as it comes and goes.

Glad no real damage was done to the radiator. I echo what Rob says about Loctite. That should keep the bolts from backing off. I think your other alternative will be constant pretrip inspection of them to make sure everything is tight before hand.

As for the wobble. Do your steering knuckles use the New Departure pivot bearing with shims? Going by some of your pictures the basic steering knuckles look very similar to the CMP ones. Is there any side to side play on the wheels if you jack up the front of Lynx? When I rebuilt my truck I was sure to follow the step by step instructions in he manual for getting these setup with the shims.
