Lynx II, hull # 4225

[Peter Duggan]

Guys,

The results of the magnaflux have provided enough information to determine that the engine can be rebuilt. That's the good news. However the pitting on the cylinder walls was extensive enough that the cylinders will have to be sleeved. There was one small crack found, but the folks at the engine shop claim that it can be "pinned". They have a fair bit of experience with the 239 and appear to be quite confident.

It will be great if the Lynx can be restored with the original major components. I do have another 239 lurking around in the recesses of the garage, but I believe it to be post WW 11, and if anything it's in worse shape.

Peter, how bad is the pitting? Will it bore to 3+5/16"? They will (apparently)go out past that and pistons (and gaskets to suit) are readily available. They can go out safely as far as 3+7/16" in a really good block. (not suggesting you risk that) 3+5/16 is considered safe enough to not have to do anything special as far as a porous bore goes, if your block is not badly rusted in the water jacket.
It will give you more cubes.
The extra cost of sleeving can be diverted to the pistons.
Be aware that there is always a degree of risk in going for the o/s bore.

Lynn , I think the blocks that suit the 3 5/16 are the C59 blocks, (later model )that the hot rodder's love to bore out because these blocks are apparently thicker in the wall. I do not think the 99A's will go that far.

[Lynn Eades]

I may well be wrong, but my understanding is that any of the blocks that were made with 3+3/16" bore, will work. The 3+1/16" blocks can only go out to 3+3/16"
If I have this wrong please someone let me know.

If you think about it
Std bore =3.1875
+.060" over bore (normal)= 3.2475 (2 1/2 thou under 3 1/4")
Add to that another ).0625" (1/16th")(or another 0.031 thou from each side) and you are there.

Guys,

Slow but steady progress on the smaller bits and pieces while I wait for experts and the larger components. Very satisfying to look at the steadily growing pile of parts that are ready to be installed.

I have dismantled the "scissors lift" mechanism for the drivers seat. It looks as if it was submerged in sea water for most of it's life. I am looking to source - C19SR 110327 - screw - special shoulder - seat riser assembly. The thread size is 5/16 -18. I am hoping that it was used for by Ford for more than just the Lynx seat. If anyone knows where I can obtain them, please let me know. I am looking for ten.

Thanks, Peter

Folks,

Went to Odessa on Saturday looking for inspiration from old green iron and the people responsible for them. The folks from F.M.V.A. did a great job and there were even more vehicles than last year. I hope this trend continues. It was a very worthwhile event. Only disappointment was the absence of the Hammond barn gang.

Please excuse my bias for CMPs and old B model Macks.

Peter

Peter, when the part number prefix is the same as your model of machine,(CS19R) Then it means Ford never had that part in their system until they built that particular machine. It may have then been used in later Fords, but I suspect it is special to just a few war time machines.
If you have some made, some originals may then materialize. That seems to be how it works.
Another angle is to check out the various parts lists from the different suspension seat makers like Bostrom etc. Some have scissors that may have the type of bolts you are looking for.

Hi Pete,

I had a couple of my seat riser bolts which were beyond saving, two were snapped off at the raised section and three others had the tread ruined. What I did was to machine off the bolt section in the lathe, drill through the centre of the remaining part with the shaped head, machine up another bolt, allowing for the split pin and then silver soldering the new stub end into the shaped bolt head. I was fortunate enough to have all 10 of the bolts to reclaim. Maybe that is what you can do if you have all 10 (110327) bolts.

I'll show you my overflow tank manufacture as soon as I get back to continuing the restoration story of hull no.1726. (Next week I hope).

I hope that this idea helps you.

Regards Rick.

Peter,
That seat is almost a direct copy of the one in the Daimler Dingo, even down to those screws, although I suspect the thread is different (Daimler was BSF). No consolation though as I doubt you would find any nos Dingo screws.

Guys,

With the engine in limbo, decided to move onto the hull. The floor needs some welding repairs before I haul it off for sandblasting and primer. Rotated the hull so that I can clean and prep the area before tracking down a welder.
The cost of rebuilding the original engine escalated to the point where I am trying to track down a more cost effective 239 engine. Some promising leads. Wish me luck, Peter
