9N Valve Kit Replacement

I need to redo the valves on my 9N. I am seeing rotating exhaust valves and non rotating exhaust valves. Is there anyway to know what I have before I tear into the engine? As far as I know its never been apart. I haven't done valve work before so this is all new to me. Thanks,
 
Fullers Farmalls ,No way of telling what is in there without removing the covers.99% chance they are non rotating exhaust valves in there.Exhaust valve rotates were used in engines that ran high hours to keep exhaust valves from burning,not needed for low hour occasional use as most are used now days.It is best to get your valves done at a machine shop unless you are experienced at valve work and have all the necessary tooling to reface valves and grind the seats. So you say I haven't done valve work before so this is all new to me. It is best to have the work done at a machine shop including a welsh plug removal and block boil out and cleaning,deck checked and resurfaced if needed,sieve replacement and oil pump rebuilt with (correct gear diminutions)(many are wrong) and proper clearances.
 
Thanks for the heads up. I was hoping to get the kit from here and dive into it. I know about valve lapping and am pretty mechanically inclined. I might have to take it somewhere though because the other stuff is definitely above my pay grade.
 
Yes take it to a good quality machine shop,ask them about doing a old Ford engine sieves,valves and oil pump and save yourself all the grief and headaches.I know you would like to do all the work,self gratification ect.but some things are best left to a professional.You will be happier in the end. Read some of the archives about oil pump rebuild problems.

You have your answer , you won't know until you remove the valve covers and see . You will probably find you need adjustable lifters . I doubt you will find a machine shop that will do a valve job with the old style non adjustable lifters . There is not much money in a low profit N valve job to start with and shops have to turn some big bucks to keep the doors open these days .

With that being said , why do you think you need just a valve job ? Usually the rings are not far behind or they are already losing pressure .

Personally I would go all the way or throw in rings , gaskets , and lap valves for a few more good years of use . The good news is these N's are probably the best motor to learn to rebuild , you would almost have to try to fudge it up as even a poor job will still run OK . This group will keep you on the right path if you do it yourself .
 
It runs fine when under heavy load but pops a lot when idling. It needs something. I redid all the wiring and split it last year to put in new clutch seals. I think I could handle the work. I just
didn't know what the rotating valves are. I will tear into it this spring and see what happens. I think I could do most of the work myself. And I'm not afraid to get the tools to do the job. I
just wanted to make sure that I got the right parts. I'm pretty sure that these have been rebuilt in small garages all across the US. I am going to try and avoid taking it somewhere as much
as I can because unfortunately money is going to be really tight this spring.
 
e="Fullers Farmalls"](reply to post at 21:47:08 I think that even if you have rotating valves you can replace them with standard valves. It will not make any difference on the low hours and light work these tractors see now.

Converting to the newer 8N adjustable lifters is easy. Remember to use your 9N springs as they are stronger and you will need a new head gasket. Once you get all your parts ready here is a link to a how to document I made to help you along. I've done several N's this way and have never had a problem.

oops! forgot we can't mention that other site. Shoot me an email and I'll send you the word document.
 
question to all. Im doing a valve job on my 1939 N right now. I removed the old valves and the valve guides do not have a rubber seal on them. The new kit comes with a rubber seals. How critical are they? Are they needed? Why i ask is cause they are being a real bugger to get in with the seals as in I cant get them in at all. whats the trick?
