    Posted: 12 Sep 2013 at 8:29am
Hi everyone
I have just picked up a Howard yeoman Rotavator and I need to know what size wheels/tyres this model used,both tyres at shot to bits and I need to be able to push it up ramps into the back of my escort van to bring it home which will be a task with two flat tyres,will any other wheels/tyres fit from a 350 or a gem just to make it moveable ?
The yeoman is fitted with the Villiers 40 engine and I can't find a pdf manual anywhere on the internet if anyone has one I would be glad of a copy.
Thanx in advance

I sold my Yeoman 2 weeks ago to a friend who wanted something to restore this winter.It went in the back of my 2008 VW Caddy van OK but i had to remove the handles as they are a long machine.The tyre size i think were 350x10 or 400x10 or 350x12 or 400x12.Sorry i cant be 100% certain on which size it is untill i phone the guy at the weekend who brought it from me to confirm as i will be helping him do odd jobs on it.Incidentally the engine on this one is a BSA 420.

Hi Stuart
Thanks for your reply,the actual size of tyres is not important as I will know that when I go to collect the machine,what I'm trying to accertain is what other wheels (that I may already have with air in them) will bolt directly onto the Yeoman to allow me to roll it up ramps into my van as the tyres and tubes on it are rotted out and are dead flat.

Cheers guys (& gals)

Just a thought. Will it roll on the rims without any tyres?

Hi charlie
That's what I'm hoping,only issue is it has to go up planks into my escort van and its going to rain all day today and tomorrow so will be a little hairy lol,I managed to get a series 2 gem AND a 350 into the back of my old short wheelbase Vauxhall frontera after I removed the rear seats
(Then proceeded to run out of petrol on the bottom of a damn great hill and had to push it up the hill and over the top to get the fuel back to the engine so I could drive it the 1 mile to the nearest petrol station) but that's another story, isn't it amazing how many people drive past you laughing while you struggle pushing a vehicle ( hope they need help too one day and the same happens

Brute force and ignorance it is then Grrrrrrrrrrr!
(That's me getting psyched up for the job in Hand

Hi guys

Thank you for the help and info,managed to drag,kick & scare the yeoman into my little van,tied the doors shut with a bungee strap,the machine is only a couple of inches longer than my 350 so not a problem,upon paying for the new toy the guy handed me (what he called a clutch dog??) He said it had cost him 80.00 a few years back but never got around to fitting it (so I guess its a job that needs doing) I'm really in need of the manual know lol,even an operator manual would be of help as there are all sorts of leavers that I know nothing about let alone changing a clutch dog (is that like a fashion accessory like a clutch bag there is an threaded hole on the back of top of the gearbox (I'm guessing something should be screwed into this?)
What is the lever under the lever that releases the height control for the handlebars it goes a cross the frame from left to right? So many questions

Any help appreciated

Regards

I think the archilles heel of the Yeoman was the rotor engaging selector / dog which is a bit on the small side.The rotor assy is designed to be quickly detached from the rest of the machine.....just pull that lever you are enquiring about under the front of the handles and the whole rotor assy will come off.Then inspect the steel drive dog and brass selector fork.If the control lever has not been keep in adjustment properly then these items will be worn,the dogs will be rounded,the brass selector will be worn etc and the rotors may jump out of drive.I still have a NOS steel rotor gear for the Yeoman above which i never used.This is more than likely the "clutch dog" which you was given.
The 4 control levers are.....diff lock / wheel lock,HI and Low and Reverse,First and Second gear,Rotor drive.They are all marked up on the frame

I can only concur with Stuart , my father bought a Yeoman brand new , and the engaging dog was a dreadful weak point , it had a new one almost on a yearly basis , other than that it was a good durable machine.

Hi guys
Thank you to Stuart & Andy for the info you posted,I will take a look at the machine when I have a min but I think that the bits I have been given Is numbered 66 (sliding dog) on the parts list in the manual I have posted the link to and the other part meshes to it by the looks of things,I'll take another look tomorrow and re post

The NOS part that i have looks the same as the rusty part at the bottom of your picture.It has an internal thread which is a Left hand thread.This screws onto the rotor drive shaft and is the "fixed" dog.
Your new,shiny clutch part in the picture appears to be the "sliding" dog selector to put the rotors in and out of drive.Both these parts should fit together.
Your other part with the brass nut / bush i guess would be an internal gearbox selector part.

Hi Stuart
Thank you for taking the trouble to look it up for me,I have been looking over the Yeoman manual (gearbox diagram)
And you are indeed correct about both dogs'the other part is indeed a selector (although I appear to have parts missing probably in the bottom of the gearbox) in the manual

I have these parts

Number 66) sliding dog p/n 16598
Number 165) fixed dog p/n 16597
Number 69) Selector p/n    16704
Number 71) Bush.    p/n    16622
What I have not got
Number 67) Selector block p/n 16705
Number 70) key.           p/n 16704

In my picture I have the selector upside down in the bush and this screws into the top of the clutch housing (into the threaded hole on top of the housing I asked about in an earlier post,or was about to lol)
The shiny round bit on the end of the selector is actually what's left of the selector block that locates into the recess on the sliding dog.

All I have to do now is work out how to remove the housing and install the bits I have (oh and also locate the parts I do not lol)I don't suppose its as easy as 1.2.3 is it lol?

Hi there Stuart
I went out and had a look at my Yeoman this morning and found a number on the right hand side of the tube running from left to right across the end of the handle bars,
it is Y (or v) 5861, and it does not have another lever on the right hand handle bar either so I'm guessing its an early model which does not have it.

In answer to my own question (how to remove rotor assembly bto change clutch dogs) it was not as easy as 1.2.3 it was more like 1.2 CLUNK (as I pulled the lever not a lot happened until I pushed it a little more then the whole thing fell on the floor, narrowly missing my slippered toes

(note to self put steel toecaps on ALWAYS!)

Now what I need is the parts I don't have, at ideas? Do standens stil have such things in stock would anyone know?

Stuart I heard you mention in another post that you had a part that you never got to use on your yeoman? I'm thinking it maybe an idea to hold spares if this is such a weak point, if you like to part with it pm me and let me know what you want for it.

Cheers

I have sent you a PM
The selector block you have missing is made from brass (or possibly bronze).If i still had my Yeoman i would of removed it and got some dimensions for you as im sure one could easily be made.

Hi Stuart
Thanx for the pm (sounds fine to me,I'll wait)if the guy you sold the machine to ever drops the rotors off and your about those dimensions would be a real help,I'm going to try Chester Hudson to see if he has such a thing as without this part the machine is useless even though it now runs nicely.
I don't know if I can work out from the parts I have what I need as there is still part of the old block still attached to the selector arm ( see picture) all I need is a block of brass machined to the width of the channel in the sliding dog and machined to fit the radius of the cylinder all I really need is the measurements I guess.

Thankyou for your help thus far

Yes its worth giving Chester a call as he may have a selector block.
I,ll let you know if the guy does not buy that spare fixed dog from me   .
Next time im around his place i,ll take my camera and get a photo of the rotor selector mechanism as i know it does need to be removed for repair (the brass selector block is worn and we are hoping it can be "built up" by brazing ).
