Valve spring compressor and a torque wrench to plastigage the crankshaft journals. Probably borrow them from the auto parts store. NAPA use to have loaner tools. Perhaps other auto parts stores. You will need other specialized tools as you get deeper into the engine.Eric85 wrote:What I'll need to get for tools and parts to pull the head and remove the valves.
Parts. Do not order any parts until you have determined what you need - have measured the engine parts and assessed needed machine work and parts.Eric85 wrote:Right now I'm trying to get a list of things I will need come spring when I can get it inside to pull the head. So far I know I'll need a can of kroil. But I'm also thinking of getting plastigage, some push rods, and a head gasket set, and maybe a oil pan gasket.
Use the .002 - .006, or the red stick.Eric85 wrote:In the plastigage kit it came with the "green" 0.001 to 0.003 inch and the "red" 0.002 to 0.006 inch.
Running clearance is the measurement between the dry (no oil) bearing insert and the dry crankshaft journal on a newly rebuilt engine. Maximum permissible clearance is = time for an overhaul. Kinda a rule of thumb is that you want .001" of clearance for each inch of crankshaft journal diameter.There are three main bearings on the crankshaft. What I'm confused with is the difference between the main bearing running clearance which is 0.0009 to 0.0039 and the Maximum permissible main bearing clearance which is 0.0055.

That definitely helps.
I was thinking;
When I go to torque the bolts on the main bearings (to 78 foot-pounds) I think I’m going to have to use an extension on my torque wrench.
Will the extension on the wrench affect my accuracy? I’m using the clicker type torque wrench.

I used the "red" plastigage last night on the center main bearing. I wiped everything clean before I used it and after torqueing the bolts to the 78 ft lbs I got
I have not done the other two bearings yet. Question I have is should the bolts be dry? I didn't clean the oil off of the bolts before re-torqueing them.
Also will the temp in the garage affect my results? It has been pretty cold here in NH, I bet it was around 10 degrees F in the garage last night.
My plan is to do the other two bearings tonight. I'm also going to use a different torque wrench tonight to see how it compares to the one I have been
