This may be one of the stupider questions posted here, but me not being a mechanic...I just purchased a B and the previous owner told me that he thought it may need a crankshaft, throwout bearing and maybe a block. The block appears not to be cracked, so my question is -- is this engine worth rebuilding or do I need to find another engine to rebuild and just swap them out? I just wanted to know before I tear it down, if it isn't worth the time, I will find another engine.

Pull it apart and then mike everything up..And go from there. Sleeves are available with complete crank and cam shaft rebuilds on the net.I rebuilt a 39 B from the bottom up. Ihave never seen a motor so worn out! The oil pump drive pin on the cam shaft just wore off... Guess what happened to the motor. If you are serious about restoration criuse the net and find parts new and used. Have fun

What Steve said, open up the engine and see what your dealing with. I would guess your biggest problem would be lifting the engine up and away.
You can open one up in a couple of hours. strip the tin, raidator, valve cover, rocker arm assembly, head bolts, lift the head off, and remove the pan. You will be able to inspect the valves, and cylinder walls from the top. Pull the rod and main caps and instect the bearings. I have a bunch of pictures in my fotki site that will give you a look on the inside. www.fotki.com/DickL The albumn below is of a Allis C. The disassembly of the little B albumn might help and at the end of the tractor pulling albumn has some pictures of the little Allis engine.

why does he say its all junk? if it dont run, it only takes 2 days to get it all apart and look to find out what is really wrong and what it would take to repair.

The first thing is to try and get it running. Check out the spark, gas to carburator, Maybe check valve clearance and see if valves are free if it hasn't run in a while. If you can get it to run you will be able to tell soon enough about the condition. Some cracks can be repaired, some can be lived with. Crankshafts can be reground, or built up with sprayed on metal and reground. As for the throwout bearing, if the clutch works after the engine is running it is ok to use. Find yourself a manual or two, it will be money well spent. And keep asking questions here, people here are very willing to help.

Today's Featured Article - A Towny Goes Plowing - by Anthony West (UK). I live in an area renowned for its rural beauty. Small fields with hedgerows and trees are common place, as are small hamlets with village greens and the odd duck pond complete with swans. The center of any village once the shop is closed is the old tavern. Rustic places with cheerful names like "The Griffin" "Red Lion" or "The Plough and Harrow" are found dotted around the country lanes all over the place. The warm glow of yellowish light can be seen for quite some distance at dusk, and ... [Read Article]
