Re: WK40 Mccormick - how many are out there ?

that looks like you will get some good parts, on factory rubber wheels, is it a 4 speed?
G'day Jake. Yes it has a 4 speed transmission. The tractor was lacking rear rims and a drawbar along with other small misc. I'm hoping to locate a factory swinging drawbar some day.

Are the WK-40's fairly common in Australia? I find the older Chamberlain's very interesting especially the models with Detroit power.

Re: WK40 Mccormick - how many are out there ?

yes there are a few Wk-40's here, I have #6318 a 3 speed, I do see more WD-40's tho. Never seen a gasoline model till I went to the USA.
Most 40's here are 3 speeds, not sure why. Just got a Delco 6V starter for mine.

Jake.

Re: WK40 Mccormick - how many are out there ?

The front half of the W-40 water pump closely resembles the one used on the Farmall M's. I'm wondering if the double pulley off the M pump would fit on the W-40 pump.
Lee and I have been doing a little research into the water pump pulley issue. Because it is a direct descendent of the W-40 we decided to get a water pump off a W-9 instead and compare the pulleys. Lee located one at Pete's Tractor Salvage in Anamoose ND and brought it over.

Check out the pictures. It looks like the W-9 pulley will fit right on the W-40 pump. Will know for sure when we try and make the switch.

Re: WK40 Mccormick - how many are out there ?

I own the following WK-40 McCormicks..

WKC-4460
WKC-4462

I wonder if #4461 is still around..The one WK has 16.9x34's on it..It also has a gas manifold and a TA-40 crawler hood..

The Wards 32" rear tire on the other one blew out not long after getting it..




Back 35 years ago there were a bunch of WK-40's in my part of the country..I once owned (3) WK-40's,(2) WD-40,s,(1) WA-40,and (1) W-40 4 speed..

The W-9 double pulley water pump fan hub and pulley flange will fit right on a W-40 water pump housing. Except for the housings and impellers all other parts interchange. There is no part number or description for the double pulley fan hub in the W-40 (TC-19) parts book. It was only available as a complete water pump unit for the electric start option.

Here is how the part numbers shake out:
2369 D......W-40 pulley hub
2370 D......W-40 pulley flange
2370 DA....W-9 pulley flange
???????.....W-9 pulley hub. I found it very strange that there was no part number on this hub. Maybe someone out there with a W-9 parts book will chime in to supply one.

The only other part my parts book (TC-32, W9/WD9) lists is #8023x, fan & generator pulley hub with oil seal.

Re: WK40 Mccormick - how many are out there ?

Note that 2369D is also in parts books TC-33 (O6, W6, OD-6, WD-6) and TC-25 (T14 and TD-14). If it fits, it fits, is probably the best answer.

Eric....Thanks for the info. This means that the fan pulley hubs off of Farmall M's and H's will also work. That makes it a very easy part to secure for those interested in converting their W-40's to electric start.

Re: WK40 Mccormick - how many are out there ?

Interestingly, the part number shown in the MD/M books is the 8xxx number shown for the 9 above. Not sure why the O6/W6 book would have the 2369D unless, again, it is related to the engine speed and the desired generator speed.

4421 is indeed a 1936. All WK-40s are 1936 model year except for the exceedingly small possibility of a few 1937s tagged as WK-40 in the model block. As for value, look at what runners have brought and subtract $1000 for a manifold, and keep going. It appears the rear wheels are correct so that is a plus. W-40s are a money pit and parts are made from "unobtainium" so be careful giving too much for one you haven't had a chance to operate yourself. There are many unknowns such as, will it carry any oil pressure with anything less than SAE 50 and at more than 30 degrees F? There are 7 main bearings and 4 cam bearings, all with appetites for oil that dwarf the capacity of the undersized oil pump IH chose to use.

Re: WK40 Mccormick - how many are out there ?

Its very complete. Missing only the mag. I know the original tool box lid is even with it. All lugs are there and in good shape. Any idea what a runner is worth? I'm not schooled in the value of these so I'm I'm uninformed. It'd look good next to my wide front steel wheeled Oliver 80 tho

Re: WK40 Mccormick - how many are out there ?

Carl - There is a fairly rough 40 on a recent eBay listing at 3600 or something like that. Now, there were no bids so it is hard to draw conclusions from that. I would say a runner with original wheels and original engine (and isn't showing signs it will immediately need to be opened up for major engine work) ought to be in the $4000 to $7000 range depending on how nice it is and what other features it has (W-40, factory 4 speed, road gear, with cast wheels, decent tires, and proper electrical equipment is going to push you over the top, for example). Steel wheels won't necessarily help the value in many circles. It's unfortunate but true. That's just my two cents. Diesels, maybe twice that.

Re: WK40 Mccormick - how many are out there ?

Thanks Eric. They haven't priced it to me yet. It might be cheap. Id pull the lugs off during restoration and replace with rubber grousers. I've always liked the WK40's. It seems to have lots of compression. The manifolds been repaired at some time with epixy so it appears to have run some time in the not to distant past.

And for myself the steel wheels is what makes it for me. Id be looking for steel for it if it was on rubber

Eric...These W-6's would have to be non-electric crank starts as the 2369D fan hub has no generator pulley on it. It hardly seems possible that there would be any customer demand for this "option" by this time. Think it was brought about by the WWII shortages? IHC seems to have been quite adapt at using up their old stock parts on newer models.

Re: WK40 Mccormick - how many are out there ?

The "Search" continued from post #39

After about 3 weeks the weather moderated and the trucker was able to load and haul both tractors. I found the "safety" chain that was securing the wayward rear tire to the steering column to be a bit interesting. No rear wheels turned on either tractor so I ended up winching them off the trailer with my C-5 logging skidder.

The rear tractor is #9842 which I introduced earlier. The front tractor is a electric start 4 speed which suffered from fire damage on the top side. The fenders, gas tank. and hood all suffer from heat distortion. The tag is gone...probably melted. The intake/exhaust manifold and the 32" rear rims are junk. I think that this is a later model than #9842 due to the changes to the oil filter. The engine # is WTM 1707K. I find the front/rear tire combination a bit odd. It seems unlikely that a customer would have ordered his tractor with factory rear rubber tires and front steel wheels.

Lee and I were also able to secure a nice JD 4-14 ground lift plow along with the W-40's.

So now the work begins.....

Re: WK40 Mccormick - how many are out there ?

Bahart - Nice picture of the wheel. This has the shoulder for the dual extension drum. Briefly, dual 32" wheels were approved for the W-40 and WD-40, then disapproved by IH because of insufficient clearance between the tires. I wonder if this might be part of one of those setups. One last thing I'd ask you to check. Is there a spacer between the hub and the seal sleeve on the inside of the hub? If so, these could also be an F&H center for dual wheels on an I-9, I suppose, although I have an I-9 on duals and the hubs do not have these markings.
Eric, here are some pictures of the outside and inside of the F&H hub. I also took a picture of our modified air cleaner hose to accommodate the starter.

Re: WK40 Mccormick - how many are out there ?

We just bought a '36, has a cracked (like grand canyon size) in the exhaust manifold, and a pretty decent sized blown out chunk in the intake manifold. Anyone have a source where I can find a replacement? It's hand start right now, I'd like to find a starter because it's hard for Dad to start as is. I also need to find the grill emblem too.
