Using a bent PTO shaft cause damage?

[Todd 22]

With the help and encouragement of the forum I’ve gotten my 8N tractor running and holding fluids. The engine is running great and was time for its first assignment which is to run my log splitter. It split the a cord of black oak without complaint but the PTO shaft is bent which causes the PTO mounted pump to wiggle. So my question is will bent shaft cause additional damage to the tractor or the pump. I realize you can it a new one for about $150 complete with bearings and seals but I’m a little low on cash after the holidays and set a of tires is a priority. Thanks in advance and Happy New Year. Todd

P.S. I’ve attached a b/w picture of the old girl after she ran for the first time after spending 2 months in this novice’s workshop for you enjoyment.

I think your instincts are telling you the answer. Bent shafts cause excessive wear someplace. Seals can go quicker, couplings wear faster, vibration loosens things and makes it all worse.

The real question is how much is too much. My guess would be that each application has it's own answer.

Nice picture however.

BIGGEST 8N I've ever seen! :lol:

Those tires look pretty dern good compared to mine. I believe I'd make the PTO the priority myself.

a bent pto shaft is not a good thing,however are you running your pump with it attached to a over running clutch?ive seen alot of them wore to where the wont run straight and will flop around all over.if you are try removing your orc and installing your pump directly on your shaft,or if neccesary on a straight solid adapter from 1 1/8-1 3/8 if your pto shaft has not been changed to the larger size.if you are running orc see how much sideways play you have in it.

By the way,most pto pumps will wiggle some from th way they are made,shoot us a picture of what pump you have and how it coupled to tractor,you may not have a problem.

Those tires look fine to me but if they aren't, run them until they won't run any more. It looks like you've still got decent tread on the back, with the lugs a little bit ragged or covered in dirt. The fronts have some cracks and weather checking, but still look decent. Either way, that PTO shaft really should be taken care of.

Todd: A suggestion--repair or replace the pto, then take an angle grinder and smooth up the bars on your rear tires and paint them with black tire paint. I did this to a 2N I restored that had the original tires and wanted to save them. Turned out great and the damage to the bars was hardly noticeable.--Bert

Since you are asking us a question that deals with the BACK of your tractor.. a shot from that angle would have helped.

If it is the shaft that is bent.. then yes.. running it WILL eventually cause problems.. then you will need tires.. and a new shaft.. and possibly a new pump.

If you have a sloppy ORC on there.. remove it.. it ain't helping.

A pc of the back and the setup will be like 1000 words, as the saying goes.

I removed the OTC and it is better but not great. Before I removed the OTC it was out of round by approximately 3/8". Now it about 1/8" off now. BTW... the picture is from the good side. The tire on the other is missing a chunk about the size of an orange between bars and I can see the tube. I was afraid to put load on the tire for fear it would fail.

Ok if you have a pump with a round input shaft,coupled to a splined adapter,i would run it its normal.if you have pump that slips over pto shaft,you could be ok depending on how much wear is in bushings,you can check runout on pto shaft,but i would advise having a helper with his foot on the clutch when you do.if you want to check your pto shaft pull it,and lay it on a flat surface and roll it slowly and you should be able to see if its bent.

Ya shouldn't have polished him up just for a picture....grin. Ever thought of re-sizing, before you submit...whopping HUGE pic.

Check to see if your shaft is the old style 1 1/8 and see if someone has slid an adapter sleave on it. they ae thin and wear out, and could be the cause of the 1/8" out of round wobble if the sleave is bad.

If the tire is good enough to dismount, pull it off and cut a section of a big truck rubber mudflap and glue it into the tire as a boot..

I've seen tires with pieces missing where the owner use a section of a donor tire and laced it up with bailing wire after drilling the holes with a drill.. also say a section BOLTED on with carriage bolts.. both had a thick rubber boot on the inside to save the tube... both tires made it many more -years- before being replaced.
