Finally getting the Bamford back together after waiting for the crank grinder. I sold mine a few years ago, wish I'd kept it. Also how to keep those banjo fittings from leaking which is a huge problem with the China and India parts. These are called Dowdy washers or Bonded seals depending on where you live. They have a soft seal to take up irregularities and a hard washer to tighten against. Your connection will be leak free. Now 9 Bamfords sitting here, anyone want a job????

Who says you can't polish a turd,LOL :D

Those oversize twins have a lot of continued issues. I tell everyone who brings one here to keep the RPMs low and output 16HP or less.

I am not aware of any records for pumps.

Your numbers break down to this
D- model
H- hopper cooled
Z- anti clockwise rotation
8- added to 1950 is 1958 production

Bob, at one of the Amish sawmills I work part time everyone goes to one back corner to relieve themselves. The mill is sided with tin and it is rotted off about 3 foot high from people pissing there, LOL

Bob, that's the same problem I had when we moved 8 years ago. My shop work was shut down for over a year while we remodeled and moved and I build my shop. Work kept coming in and I had quite the pile when I got going again.

Eating supper tonight,
A truck backs in driveway with long trailer, Hmmm what's this all about??
Driver says he has two engines for me, Uhhh what??
He has a note, says repair as needed signed xyz Amish fellow from 3 states away.
 2 Z3 Bamfords they are the 7HP version. Out to the barn they go, many engines are a head of them. Hope he is not in a hurry!

Ahhh Butch,

You are, as always, a fountain of valuable information!
Have you tried this method yourself?
 
Thanks again

Cheers

Glad it worked for you,
As for corroding the flywheel to the shaft if you can let the engine sit a while you could try relieving your bladder withbit directed in the area of the shaft, flywheel junction???😅😅

Pull both gibb keys and then push them back in by hand as far as you can make them go. Then push on one flywheel rim while pulling on the other and reverse that motion. If there is any more than the slightest movent back and forth on the keys it is likely the problem, especially the one that goes in a long way before it tightens. You need some shim stock about .010" place a strip under vthe key that goes all the way in before tightening. Then tighten the key and start the engine. This usually isnt a permanent fix but will tell you if that's is the problem

Just a few more pics. The normal overhaul on one of these is 2x what a Lister costs due to all the hand work and lack of cheap parts.
Bamford uniquely shrouded intake valve. There is a rotation stop built into the retainer so the valve cannot rotate. Ordinarily all this goes in the scrap bin and new oversize valves are installed but this engine is low houred. We ground the valves, touched up the seats and it's good to go. Also shown is the copper sleeve for the injector bore. This separates the coolant from the injector. They are always rotted out or close to it. Many of these engines are half full of stop leak that was dumped in an effort to avert fixing this problem. The tubes are shop made as is the tooling required to swage it in place so it doesn't leak.

I have a Lisle ridged hone and a wide range of attachments for it.

Some pics of what we go through to properly rebuild these. No more big end bearings existed for these engines that anyone knows about. Custom made bearings were the answer but complicating things is the 4-5HP Bamford used two different I D.s in the big end of the rod, early thick she'll bearings and late thin shell, both use the same 3.000 crank pin. Now, when all the possible I.Ds and undersizes are considered the number of stock bearings becomes quite large AND expensive. Also complicating things is there isn't a market for 1000s of bearings. The answer became having one size custom bearing made that would be as adaptable as possible. I had bearings made for the large rod bore and all of the them are 030" undersize. It's much cheaper to grind the cranks 030 under than to stock all sizes of bearings or than having them welded and ground to standard. Pictures show the current Z2 4.5HP project. Boring the big end on the mill, then it was honed to size and locking tabs machined. Also shown is the finished rod and the newly made inserts. Now off to the crank grinder to have the pin sized to my bearings.

Bruce, I have several 4-5HP  cores that belong to me and can be made available as rebuilt.  We can add your engine to the list!
The rebuild process is pretty basic, I'm just the guy who was willing to make the required investment in tooling and  inventory of reproduction parts and pieces. Unlike a Lister where anyone can purchase parts a Bamford owner must either deal with me or have one off parts made at $$$$ prices. I don't sell the parts except in very special circumstances, parts are used here and that locks me in for the shop labor and my labor pays the bills around here.

Bruce, the Bamford are worshipped by certain Amish. after being thoroughly abused for many years they could no longer keep them running so they put them away. Now that my little operation has been discovered they are coming out of the wood work for rebuilds.

Bob, I make my fasteners from 1044 bar, known locally as Stress proof. it is fine for applications to Grade 8. I don't substitute in crucial areas such as big end bolts and nuts but all others are fair game.
