You could use Loctite retaining compound on the loose fit gear. but to find the correct position you may need to use a dial indicator and some packing until it cures

Inge,

if you no longer need the fixed jet #11 I would buy it from you.

Sorry for late replay.

@Hogay: Now I got it. I bought a new gear, now its much better
@Jacek: I never had the jet #11, sorry. I can´t find a shop here in Europe, so I want to configure the M-54 like M-51.

I cant find the tourque for the alloy heads in my manuals. Is 65 ft labs (88.1 NM) correct? Is there any specific tighten order?

Thank you :)

Torque the bolts in a cross pattern (think points on a star).

Torque the bolts in increments, starting with a lower torque setting on your torque wrench, and go over every bolt in a star pattern several times until the bolt stabilized at your torque setting.

I would start with 21 ft pounds to start going over the star pattern till toque has stabilized, then increase to 42 repeating the torque pattern until stabilized, then finalize the torque at 60-65 ft.

Check the bolts the next day to see if they remained stabilized at your final torque,

If you’re using copper or original asbestos head gaskets ….. to me allows for gasket compression and bolt stretch.

Others will probably chime in with their experiences

65 ftlbs (85~90Nm)...in two or three steps.
Make sure to torque in a cross patern, that's most important.
And retorque after first heat-cycle, and again after the first 100mls or so

^^^^^

Except for the torque check after first heat cycle, an after running it for a hundred miles or so……

Isn’t that what I said too???

And just to further clarify:

According to the US Army Maintenance manual for WLA’s.

TM 9-1879, dated March 1944, page 35… step (5)…I quote:

“Head bolts must be tightened evenly to attain a tight joint.

First turn down bolts just snug; then tighten each of them one eighth to one quarter at a time until they are all securely tightened.

Use special head bolt wrench (41-W-1525).

If torque wrench is available, tighten head bolts to 60 foot pounds minimum, 65 foot pounds maximum tension when the engine is cold.”

Inge, I do believe this information is in the knowledge base if you care to look

George, shame on me. I overlooked you post.
Your right, the information is in the manuel TM9-1879.
I just checked the translated german version, and the value is not writen there. The manual is in the paper bin now.

Don't worry George; you're still the King... :wink:
But, Inge has a point; in the first manual dating april '41 both torque settings and a maximum speed of 85mph is mentioned.
Later (>'42) manuals don't mention any torques, and mention the maximum speed (as opted by the US Army as 'minimal required'..) of 65mph.
That's on the dataplate, so that's what the manual says..
All myths set aside, all badtalk too; a WLA should be able to do a genuine 70mph...(speedo says 80-ish at that point).
Not that you want that kind of speed out of an 75+ year old flatty, just fact-checking.

Motor starts with one kick :D, but the fuel tank must be replaced. Unfortunately the tank is sold out or very expensive in Germany.
I have a service car tank with a late style petrol valve. Can I use this tank for my WL?

Yes and no...
Yes, you can fit a later Servi-tank on your WL..no problem.
No; a WL should have the right tank.. :wink:

Like these from the UK:

...but you'll need welding skills to fix 'em

Thank you for the link. What is the difference between my tank and the eBay tank? The shifter lever mounting?
Or what makes a G tank and WL tank?

I’ll go to Washington DC today and drive down to Orlando. Is there a store nearby where I can buy a tank.

The UK tanks are for later >'48 WL/Gs.
As you can see, the shifterguide mounting lays in a tank recess.. whereas the <'47 has the guide ON the tanks.
Also, the >'48 dash is smaller, so you need to widen the recess to fit a <'47 dash.

Unfortunately there is a 8mm gap between the tank and cover. I think I cut the plate and weld together again.
Or has anyone a better idea?
