WD overhaul

My cousin just tore his 1953 wd down for a BAD case of the smokes. Turns out it has M & W pistons and the rings are fried. They haven't got the head apart yet to see what going on there. Question is, can you still get rings for M & W's? It's got a 4.125 bore. It really should probably have new sleeves and pistons but he's trying to get by on the cheap, because he's already given it to his kids and there not going to do anything with is except maybe go on a tractor ride and tinker around with it.
Any suggestions??

Had the same issue with my WF some years ago- same 201 engine. Try a Hastings ring supplier.

Try to find an "old engine shop". Hone the sleeves "in the block" (no need to remove them if they do not leak at the bottom "O" ring seals). Get the pistons "knurled" to fit the sleeve bores. Check TSC and Central Tractor Hastings - as suggested, and/or do an internet search for the rings. Be sure to grind the valves and check the valve springs and "keepers". Completely clean all oil passages in the engine block, the CAMSHAFT, and the rocker arm assembly and the external and internal oil lines. Check and correct (if necessary) the clearance in the oil pump. Replace or clean the oil pump screen, Set the oil pressure to specifications with the engine "hot and running". Do the final valve adjustment with the engine "hot and running". Be sure that you know how to properly set the rod and main bearing clearances with the use of the "shim packs". Set the clearances to specifications , but on the "tight" side. If you do not have one, get an (I T) technical service manual for the tractor and engine. Read and understand it "before you start" putting the engine back together. Be sure that the piston pins are installed correctly, they are different for different positions (1,2,3 & 4). I like to enlarge the oil holes in the center camshaft journal for increased oil flow to front and rear main bearings. Try to get a "metal covered" head gasket. Use "K & W" Copper Coat gasket compound on the head gasket. Be sure to re-torque the cylinder head and readjust the valves after the engine has been run and reaches full operating temperature - consult manual. Just what I like to do with these engines. (They are a little different than some.) Good luck in your efforts.

You will thank yourself many times over if you just purchase a complete Overhaul Kit with New Sleeves and Pistons, gaskets and all..
Then, it will run very well for many Many years..!!

Ditto on getting a complete kit. You'll never regret doing it right.

Go to www.hastingsmfg.com/. You can get ring sets or individual rings in many sizes. They will sell them direct to you over the internet.

I'm no expert but from what I've heard the factory m&w rings went as good as the Hastings ones. You Can get new piston sleaves / liners from www.external_link . the new piston kits don't have the compersion of the old M&W pistons. Look to see it the pistons are ap46 'wd' or ap48 'wd45' there where two difernt compresion highths.

you can get a set of rings for the M&W pistons from Hastings. THey have the part number listed on their website. I got a set from them last winter, though it wasn't cheap, something like $140 if I rember correctly. The M&W's run an extra ring and it's a bit of an odd set.

I would buy those old M&W pistons if they are the AP-48 if he ends up putting in a new setup.
