Definitely a non standard set up for a 300 or 350. Is there any clutch lever on the handle bars operating a belt tensioning/slackening mechanism. If there is not, no wonder you were asking how to select gears! Crashing the gears in and out will not have been doing the selector collars andy good.

Looks great Ivan, well done mate

The belt tensioning pulley assy is not original Junior.Its been “modified” presumably because the original clutch worn out.Also the engine is a later 7hp (or maybe 8hp) B&S.

Here are some pics. Phew glad that worked.

Hi Charlie, nice to hear from you. Looking at the manual you supplied, I’ve lost MT39 – Miller axel felt washer small, and my MT40 bearing cap end, I’d have thought my RC40 spring washer has gone and I may have lost the compo bearing MT361, it wasn’t on the end of the axel, but may be caught in the shell.
I guess the simplest way forward is to drill out the rivets and remove the shell from the outside? And then see what’s what. I can bolt it back in with suitably sized bolts an nylocs?
$64,000 question is will I be able to source something to replace the bearing, or will I be able to find a bearing assembly in an gash miller attachment.
I’m guessing that built in ’63 it’s now out of warrantee – poor show that like rolls Royce they’ve not sent their man round yet to fix it for me!

Hi David,

Do you know the specific colour of maroon you used to paint the dumper?

Thanks

Best wishes to Val, hope she is ok

Late Cultivator not a problem Alan, looking forward to reading it

How do I put the pictures up?

[vhgmcbuddy]

Quite possibly but depending upon how much you value the machine not a disaster and not a difficult job to do. Worst scenario is that the roller shaft drive sprocket is well and truly seized on the shaft and it has to come off to get the roller out of its carrier. Put a puller on it and it turns inside out, warm it up too much with the gas axe and you melt the plastic bearing carrier behind it. Carrier is cheaper than the sprocket but in a commercial situation if the sprocket didn’t yield so some gentle persuasion we would probably cut it off !
Try a bit of heat on the sprocket, careful use of the puller and some plus gas releasing fluid and with a bit of luck it will draw off.

Let’s have some pictures! Worth a thousand words etc!!

The story about this howard is as follows, I saw it advertised as a howard 350 but when I went to see it I saw that it wasn’t a 350 and the guy said he made a mistake and that it was a 300. So I just took his word for it as Even though it was being sold as spares or repair I thought it was a bargain. Along with the rotovator I also got the cultivator, the plough and the potato furrow at a very good price. I have now got the engine starting and going although its a bit noisy just have problems working the gears. I think the engine could be a replacement engine.
Just went and had a look at the tinwork as some of it was off when I got it. It has howard clifford 300 and a coat of arms on it if that helps any.

Sorry for the confusion Junior. Howard 300 with a Briggs engine had the friction disc clutch fitted to machine serial No 643. It was then replaced by a improved friction disc clutch. Later the cone type was used. All this of no use, as previously mentioned you probably got a 352.

[vhgmcbuddy]

I’m no Howard expert but the clutch illustrated has the ball bearing thrust race to disengage it, so doesn’t that make it a 350? Didn’t all? the earlier 300 machines had the “fibre washer” thrust? Also, didn’t the Dowdswell 352 just have a simple fast and loose belt drive engagement/disengagement system – or was that the Dragon?

[vhgmcbuddy]

The free wheel units screw to a hub which is solid with the roller shaft. They can each spin freely in one direction only and should lock in the opposite direction ie with the engine off and the drive engaged you should be able to push the machine forward but not pull it back. If both rollers can be locked with the above test I would suggest that your problem is roller slip on the ground and not a mechanical issue.
From memory the free wheel units have a small arrow etched into them to denote the direction of drive. Again, from memory I think that it is possible to assemble the ratchet units to the shaft the wrong way round resulting in no drive being transmitted to that roller.
The attached scan shows the general layout.

Im sure the model you have Junior is a Dowdeswell 352.Early models had a 5hp B&S engine whilst later ones used the MAG/KUBOTA engine.
