Thread: front PTO Identification help

Looks like a generic forward facing rear PTO.

Did you get the selector top to go with it?

It fits in the back of the transfer box in place of the the bearing support flange at the rear of the mainshaft. There are teeth on the rear side of the transfer box constant gear that connect to the slider gear (dog clutch) that you have on the input gear of the PTO drop box.

The selector top replaces the rectangular cover plate on the top of the transfer box, and the tines on the selector engage in the groove on the slider gear.

There is usually a shaft with a knob on the end that inserts through a hole you drill in the front of the seat box next to the hand brake. This shaft connects to a lever on the selector top and there you go. (some early selector tops had a knob on the top and you operated it directly by removing the middle seat and cover.

IIRC the shafting is merely 1" shaft bar to which you attach various combinations of uni joints and shafting. All available from engineering suppliers like Blackwoods.

As to the rating I have no idea, but your read of it may be quite correct. That will usually be set by a spring and friction plate inside the output shaft. The rating on the winch and the shear pin will usually set the load rating. Remember you have a lot of mechanical advantage created by the gearing on the winch (or whatever) on the front of the vehicle so 6000Lbs can be multiplied several times by the reduction of the winch gearing.

hey

yea I have 90% of the selector, just missing the last section of the handle that protrudes out from under the seat..

the rest you are spot on about... but I suppose I was really after a manufacturer, so I can get parts for a rebuild/service before installation...

just one more thing, my landy has the output/hole in the front cross member dead center... I understand that the shaft runs down the chassis rail with the aid of chassis bolt through bearing mounts, but does the output shaft exit out the center hole of the front cross member? as my landy has a 202 holden motor and the engine seems to get in the way of the front output hole, though I have read of holden powered landies having front PTO's

The hole you speak of, is that the crank handle hole?
Aaron

you taking the ****? crank handle hole lol

it would be around 4" in diameter, I have same as in the center and rear cross members, the last 2 line up with the rear PTO output of the gearbox, the front one just seems to have the block and sump of the 202 in the way...

The hole is used for the crank handle and also the drive from the engine to a capstan winch.
I think with the front output PTO you have the drive is taken under the front crossmember.

The PTO usually runs along the chassis close to the bell housing with a carrier bearing mounted on the side of the bell housing to help take some whip out of such a long thin shaft. I just pulled the carrier off mine so I could replace the bearing while the car is in bits.
