    Posted: 23 Jul 2010 at 8:03pm
Hi some of you may remember a few months back i started doing a restoration series on my little Bulldog, due to my computer crashing and then my car blowing up, it kind of lost its way.
Anyway due to a bad hip injury ive had to put my Gem restoration on hold for a few weeks, therefore I felt it was about time that I finished off this very rare little Rotavator.
I aim to show how to do the basic jobs, for the members who are new to the world of restoration.

Howard introduced The Bulldog in late 1954. Less than 12 months later, after Lanz the tractor manufacturer  took them to court, Howard changed the name to Bullfinch. This means very few were ever produced with The Bulldog badge on them, allmost all were labeled up The Bullfinch. Has anyone else on here got one?

A while ago  Keri, (My Missus) asked me what I wanted for my Birthday. I had allready spotted this machine on E bay and had after some discrete questioning assertained it was in fact a Bulldog, rather than a Bullfinch that it was listed as.
Keri said if I bid for it she would pay for it as a present. Some last minute bidding secured it for the princley sum of 16.04p. To be fair it did look very rough in the photos, but I guessed it was superfisal, - When collected from just up the road in Worcester I could see that I was right.

When I aquire any machine I try to find out what I can about its history. In this case Ive got original sales sheets for them also engine and machine operators manuals.
According to the factory records this machine, number 6431 was built on the 14th March 1955 and dispatched on the 25th April the same year to Staughtons in Northampton.

Long ago it has also been the subject of a repaint in yellow,- Cant wait to turn it Orange again!

The next step with any project is to asses the machine fully and make a list of what is requierd. With this series of Rotavator it is imperative to check the main shaft hasnt sheared, i.e there is still drive to the wheels.
This one was fine which is allways a relief.
Next all the shafts were checked for play, leaks etc and all again was fine.
The head was removed off the engine so i could see the internal condition of the engine.
A list of parts needed was drawn up;
2x Rubber handle grips,
1x tyre,
1x Starter pulley,
1x Airfilter tube,
 
On top of that a number of small dents will need addressing and the engine will need a full overhaul because at present is a non runner.

With these rotavators when i restore them i allways strip them down to a rolling chasis, i.e gearbox, pulley, wheels rotor and rotor box. This unit is then stripped to allmost bare metal using chemical paint stripper and a pressure washer. Blasting may be fine on the loose covers but I dont like it anywhere near any seals or berrings etc as the results could be disastordous.

Here is a photo of the rolling chasis minus its wheel as the one tyre was missing, the simple solution was to pinch a wheel and tyre off a scrap machine I had, one alternative would be to use a cut down cambelt, (ask your local garage for an old one).
To remove the wheel just undo the nut, lever behind the wheel with a suitable bar and give the thread a sharp tap with a copper hammer.

The engine is next in line for attention. To strip is as follows;
Remove the fueltank.
remove the airshround which is held in place by 4 bolts on the top and four small screws on the side.
Next undo the six head bolts.
To remove the flywheel youn need to lock the piston, i simply put a soft socket in the cylinder and losely refit the cylinder head with four bolts.
Early 2A's had a bolt in the end of the ropre start, later ones had a screw head, if the later fit a sutaible chisel or similar in the slot and using a spanner undo anti clockwise. Next i place a lever carefully behind the flywheel and place a piece of wood over the end of the crank and give the wood a sharp tap with a hammer. The flywheel should then pop off to give proper access to the coil and points.
Above the flywheel is a little plate held in place with 2 screws, undo these and you will have access to the valve springs.
Photos will follow showing how to clean the points and regrind the valves,  both very important jobs on these little Jap's.

trosher, the nut is an extractor, when it starts to go tight keep turning it and the flywheel should come off.

At the moment i cant give a lot, perhaps ebay in the spring may be your best bet as rotavators double then. They are rare, production of about 18mths but exactly the same apart from the name as the bullfinch.

Hello there,
I've just retrieved a Howard Bulldog from an old barn on our farm and intend getting it going for my grandson to use on his mini farm. Far more instructional for him to restore than buy a new one. At the moment it is an orange version of the yellow machine you got from eBay!
I've been reading your restoration project with real interest and have bookmarked the page as my guide! There is only one belt on the pulleys....it appears to drive the rotors...what job does the missing pulley do?
Hope you're still active and the project is running well.

Hi there should be 2 pulleys on both the engine crank and the gearbox output shaft, the idea is if you change the belt from one set to the other it changes the gear ratio.
you can see photos of similar machines on my website  including the howard bullfinch www.howardgem.webs.com
Forum member TITCH should be able to supply you with the correct decals, very good they are to.

Thanks for your help...that explains why there is only one belt...........all I need do is change it from one pulley to the other...is that right? Out of interest I'll try to post some pics though I doubt we'll do such a good restoration job as you've done with yours. The decals would be the icing on the cake so I'll contact TITCH in the near future.
Thanks again

Yes that right, just move the belt across, as its for your grandson, if you give me your address in a private message i'll drop a copy of the  bulldog operating manual and jap 2a manual in the post.

Thanks, that's really kind of you........I've replied with private message and also asking where to get a set of +0.20 rings for the Jap engine. Forgot that we also need an exhaust...I guess I could make one but if there are some used or even new ones out there I'd rather go for that.
