Right went off on a tangent. Got as far yesterday as finding room in the mill to mount the B&S motor on a right angle plate. Was about to go into it this morning with a fly cutter. Found a sleeve that brought the motor down in volume but would have fit. but after being grumpy at this extra work...

I've done some sleeves on motorcycles and cars. What makes the B&S motor silly is that you do need a lot of travel to get in on the mill. Otherwise I would go in with a fly cutter and get into it. Bit I don't quite have the height in my mill. What I do see though is that the B&S cylinder does...

I hoped this was not the case. What might be a good reliable engine push mower engine that fits this bolt pattern that can be rebuilt? That would be something with a separate cylinder or a sleeve and parts available. Has anybody thought about boring one of these out and putting a sleeve in?

Yeah this little motor is OHV. I was going to lap the valves but aside from this head looks fine. I was hoping somebody might have specific part numbers for oversize rings. I cannot find them on the B&S website. From the parts list the B&S code for the ring set is : 26 591976 SET, Ring...

I have a little 'sprinter' mower. Have had it about eight years. It has actually been a great mower for the price. Gradually it has got lower and lower on compression and has reached the point where it just stalls out on pretty much anything. Did a compression check and it seemed very low. Able...

What I did in the end was just dump the whole mess. The sprockets. All of it. Put a big lever on the side. Bit like a skid steer. Works amazingly well and feels nicer than the original steering. Some things I noticed about this were that I can now steer the mower while pushing it from behind...

Yeah that was my thought to. But what happens is the linkage out to the front/tracking arm contacts the motor. You get a narrow area of clearance out to the front steering arm where the linkage doesn't hit anything. So it seems to me that removing the engagement lever to a different setup is the...

Of course the alternative would have been to swap the steering over so that it came out the right side of the mower instead of the left. But the way Rover designed the steering it cannot be flipped. At least not that I can see. Also the tracking arm on the steering isn't on a spline! What I did...

Ah my explanation was not clear. What I was saying was that I looked at bigger drive sprockets like on the Supa Nova. This makes sense to because if one imagines the sector gear that came out of the Rover then it then it would be about 120mm in size as a full gear. Now I have space for the...

Sorry it has taken awhile to come back to this. Got the front end reassembled. It is almost good to go _but_ the ratio is not quite enough. Close but not quite. Now the main problem with all of this really is the placement of the engagement for the clutch for the cutter. I went in to the local...

As soon as the pinion turns up in the post I will come back and update this. Should be next week some time based on the tracking.

Today I turned out the hole in the drive gear. The hole itself was 19mm but of course splines. Splines were hardened. Lathe is currently in pieces so I drilled it out. Think it tore up my nice Christmas tree bit to! What worked nicely was to just grind the splines away. Slips on the...

So some digging about in my junk box found something interesting. After looking at lots of drive sprockets and some bicycle cassette sprockets in my junk pile are all the same pitch as some cox steering chains I came across. According to some blurb for a steering chain on ebay ... Width...

Think I might go with a drive sprocket off a bike. I have lots of those about in a box somewhere with different size holes. Also lots of 420 chain to fit em. Found a smaller looking pinion on the fleabay that is also 420. Now just trying to remember where all my chain pin pushing tools and other...

I just looked at the plate that carries both shafts again. I think it has an adjustment on it anyway that may be enough to let me tension a chain setup.

That is a great idea. I had wondered about a sprocket setup as well but I was not sure if I would be able to tension it. But now that I think about it what I would do is split the bottom plate that carries both the steering shaft and the secondary shaft. Then I could side each plate away giving...

I took the console out and did some measuring and then had a go in the cad at trying to come up with a layout that would let me use a linkage. No matter how I move it about I really can't seem to find the space. First thing to note is that on the left hand side the linkage for the cutter...

So I think I understood the picture? Rather than a gear does it just have a linkage from the steering shaft to the plate ? I was wondering about just putting another linkage in. I know the sector gear also gives a bit of reduction. Talking to an old lecturer of mine that is good with the physics...

I did the same and put a Loncin in my old Rancher 1755 mower and I didn't have to much trouble with the wiring but what did get me was that the fuel cut solenoid wouldn't work when wired in to the same path as everything else in the start circuit. Cannot remember the precise details right now...

Hello everybody. This is my first post. I recently had a bit of a bingle with a tree and broke the steering sector gear in my Rover Rancher mower. Part A07693. I see that this part is no longer manufactured and am having problems finding a replacement. Since the mower has the engine in the...
