Hi I have a few questions I need help with as I am putting the old girl back together.

Is the govenor spring easy to change? I assume it is easier to do before I put the rad in. Can I just use a needlenose plier?

Should I try and find brass nuts and washer for the manifold? I have anti-seize nuts I got from agco? I think the nut size is 3/8.

Do I need anything on the waterpump gasket? I didn't put anything on it.

Bolts on fan - there are two bolts on the fan - almost like de-clutching bolts. Should they be loose to let the fan adjust slightly?

thanks!

the governer spring can be changed any time. its a little tight with the hood and radaitor installed by still can be changed with a needle nose . the waterpump gasket will be fine bare. I like to put copper coat on the pump side and nothing on the block side. it makes it easier to take back off. the two bolts in the side of the fan pulley are for tightening the belt. Adjust the two halves to take out the slack and tighten the bolts.

Don't put brass nuts on manifold. When they seize you cannot take them off with a torch, and they will seize in time. MACK

when you put the manifold nuts on get you some FELPRO C5A anti sieze compound.i gurantee if you remove them in 5 years,they will not be siezed to studs...

When tightening the manifold, snug the very front and very rear nuts first, which will square the manifold to the cylinder head. Then, alternate between all six nuts a little at a time until good and snug. Now, every time you go to use the tractor (while still cold and unstarted) resnug those bolts. You will find the gaskets keep shrinking for a while and after several tightenings of the bolts they will be tight and the gaskets won't blow out from low torque on the nuts.

Use the copper C-5A anti seize if you can.

In the governer department if you decide to change the control rod seal the pin that holds the gov spring fork on the rod is tappered and must come out driving it to the front. I just found this out the hard way,the pin has about .o10 tapper to it. The pin is avaiable but not the rod or fork however I did find used ones.

Re; the fan bolts. Loosen them and adjust the width of the pully so it fits your belt while it is on the bench, then install it on the engine. 60 +/- years in the elements make it a little difficult to free it up; some snake oil and/or heat may be necessary.
