Re: 450c 6-way fittings?
You will probably find a .010 shim will change hyd pressure 80 to 100 psi

Re: 450c 6-way fittings?
When you get your new washer, would you measure thickness and post on here, in case someone else has similar problems, it would be for all to see! Also, after you install new washer and your 3 thin shims, and warm oil and pressure test, post on here what is pressure of your system, and if you have t...

Re: 450c 6-way fittings?
Another suggestion - when you are testing hyd pressures over 300 psi, do not use brass or copper fittings, they won’t stand the elevated pressure and personal injury could result.

Re: 450c 6-way fittings?
I found a listing for your 450-c on line and believe your hyd pressure is 2250 psi.

Re: 450c 6-way fittings?
Forgot to say- get a bunch of .010” and install them, if you would rather. Put 5 or so in and try it. All the washer does is make it so you don’t have a bunch of thin shims. I always install thickest shim next to spring, that way spring action over time won’t distort thick shim( it will distort thin...

Re: 450c 6-way fittings?
The T10649 washer is available on eBay , the thin shim you have should be U10562 and is .010” thick. Get a regular flat washer,( O.D. Of washer should be close to OD of thin shims), ( use a flat washer from your hood or floor plate) measure the thickness, install it, follow my previous post, or orde...

Re: 450c 6-way fittings?
You need to find out what the hyd pressure is supposed to be, and at what RPM. Then put a pressure gauge( approx 1000 psi more than what your spec is) and a good gauge, then bottom a function so pressure is max. Record this reading. If it’s low, put in .050 washer or approx,but measure so you know h...

Re: I Am Afraid of the Answer
I would try and start engine with the inj pump that is on it. It may just surprise you, and then run pretty good.

Thanks. If you could, the thickness of the plate would be excellent !

Re: 440ic Frozen Engine
Do you have to remove rocker assembly to try this way of unsticking pistons? Would you put some more WD40 or similar into spark plug holes before putting air pressure into cyl?

Re: I Am Afraid of the Answer
Lavoy is very right( again) about homemade rope crank seals. Proper rope seals are impregnated with a mixture( mainly graphite- slippery) fibreglass rope would probably be very good as a grinding- polishing compound and wear a groove in the crank in about 1/2 hr, then burn up from heat( major fricti...

Re: 440ic Frozen Engine
Did you have antifreeze in rad , or was cooling system drained to store it? When you get engine out and apart, check cyl head very closely for cracks( or have a shop clean and crack check it) very common for these to have cracks. Good , non cracked used ones seem to be hard to come by, check with La...
