My tractor has three bolts around the mcv that will no longer torque to spec (20lbs). It is developing a slight drip. Before this drip goes into a blown gasket is their a repair that can be made? The problem as I see it is that the bolt threads are stronger than the casing threads & the casing threads are now gone (because me and whoever owned it before me overtorqued the bolts). Because the mcv cannot cinch tight to the casing, the leak is now starting. Any input is greatly appreciated.

You can go in a bit deeper with a longer bolt , i have done that on a couple or you can install Keenserts on some of them and you can evern drill the MCV and rethread to 3/8th course . I have seen this problem on six or seven that i have worked on . Your not suppose to use a six foot pice of pipe to tighten a 5/16 th bolt even though it is a grade 8 . And you can also use a heilycoil i just don't like then unless there is no other way.

you can get the heli coils in kits.used to come with brill bits inserts and tap.application tool was made out of plastic.i always dabbed lock tite to the outside of the insert very sparingly.after insert bottoms out make sure you break the bottom tab off.blow it out with air. on deep holes you can use 2 inserts if i remember correctly.cummins used a similar repair for head bolts on the 855 engines.make sure the lock tite is dry before you put it all together.

There is a thread repair kit made that I believe is sold under the trade name Heli-coil. I looks like a stud with the center drilled out and should be available at an automotive parts store. They are not cheap because you should buy a special tool to install them, but there are places (like yours) where the cost is acceptable because of the alternative. All you need to do is drill out the old hole oversize (drill bits is provided or the size is provided) and then screw in the new threads. Whala, fixed good as new!

Used a Heli-Coil on W-30 head bolt. It held to 90 foot-pounds.

Those heli-coils work pretty good but you do need to tap the hole after drilling, and then use some sort of thread locking stuff to prevent the heli-coil from unscrewing when removing the bolt. Another option would be to just drill and tap the hole out to the next bigger size, and then use the next size bigger bolt. This may or may not work in your situation.

We have right at 60 degrees here. Should be closer to 30. Farmers almanac says 50 inches of snow in February. Gonna have to hurry to get that much, but I won't say that too loud.

I dunno, there is a fair amount of February left, 50 inches in 23 days (give or take) that's only a bit over 2 inches every day, or about 15 inches a week... :>)
