LT27 Gear Box

[yacaboni]

A friend of mine has an oil filled gear box that I believe is for a Wood-Mizer LT27 mill. It has two keyed straight shafts and a keyed tapered shaft at right angles to the other two shafts. It also has a plunger that disengages the gears when it is depressed. It may be for an accessory. It appears to be in excellent condition. Can anyone shed some light on what this gear box is for and if it has any value as a replacement? Thank you.

Do you have a picture?
LT27 has a rope feed and a chain gear drive for up and down.

I don't have one now, but can get one when I visit my friend next week. He had a LT27 mill, but upgraded. He never used this gear box. The gear box is left over from the LT27. Since I am new, can you explain how to insert the photo from my picture file?

Hi Marty,

I have found additional information on this gear box. It is an Eaton Hydrostatic Transmission, Model 700-042. It is apparently used for moving a sawmill head forward and reverse. It may also be used for lawn mowers. I have attached a couple of pics.

If that thing has a plunger that kicks it in nuetral wouldn't the sawhead free fall? Sounds dangerous, course I may be missing something.

It does have a plunger. I have been able to find limited info so far. I have found some info on a Model 700-001 and a Model 700-041 on the Web, but not a 700-042. The prices new appear to be greater than $500.

This is not a Factory WM part. I have seen these on small construction rollers and lawn equipment. I am sure they are used on many types of equipment. The stud you see sticking up is the free wheel pin just like WH_Conley said. I think the shaft with the threaded end is the speed control and the forward reverse control.

I have now found that Eaton lists this genarally as a Model 7. Within that class there are many sub models. I have information on Models 700-001 thru 700-040, but nothing on 700-042. I will have to do some experimenting with the unit to determine input/output rotatation direction and number of speeds. I agree that the small tapered shaft is the gear control. The push pin must be used to release pressure in case there is a stall and the transmission locks up.
