Rookie with IHC M

Hi all I am a rookie to this site and to stationary engines.
I have recently come in procession of a IHC M engine via my step son and don't know it's age or what horsepower. All I know is it, since the identification plate has been purloined from it all can I tell you about it is it has IHC and 9700T cast in the block. It has a 3 valve carby (gas, kero, water) and a Bosch FX1-ED1 magneto, there is no spark. It is also missing the oil dripper and tube. The valve rocker arm is broken. Can anyone help with identifying what hp and if I can obtain a replacement rocker arm?

Welcome to the Stak!
You've come to the right place to find information on that engine.

If you could please post a picture of the head of the engine, I would be able to tell you what horsepower it is.

Occasionally, you can find parts for iHC M engines on EBay.

Have fun!

Re: Rookie with IHC M

Hello Dobba
You (or your son in law) certainly picked a winner for a first engine. That magneto configuration is quite unusual to find and the engine seems to be in amasing condition overall.

I don't know why your thread was moved as you'd get local help if it was still in the down under section. Maybe ask a moderator to move it back.

The hp of your engine can be found easily by the flywheel diameter.
The rocker arm you need can be found easily in Australia and I know 2 people who would, more then likely, have them at hand.
I wouldn't worry too much about the no spark yet as those magnetos are fair dinkum dandies. I wouldn't mind betting it's dirty points or dirty slip ring or bad grounding somewhere (more likely inside the magneto) that's stopping the spark. I'd be surprised if it had to be rewound.

As for date I reckon your engine is around 1922-1924 because of the magneto type. The hp will play into the build year. I'm guessing it's a 1 1/2hp because of the size of the engine compared to the size of the magneto. If it's a 1 1/2, then 1923-1924.
Your engine has some nice features like the gib key guard on the crank side.

Cheers Scott

Part number only. The only place a serial number is on these is on that missing plate.

Measure the crank diameter. If it's 1 1/4 inches then it's a 1 1/2hp engine. If the crank is 1 3/4, then it's a 3hp.

Re: Rookie with IHC M

measurements seem to match 3hp.

its a bit hard to read in this reprint book i got, but it when compare the 'S' digits to the other fractions digits, it matches 1/2 and does not match 1/4 for a 1 and half inch crank, which matches 45mm. flywheel also closest to 3hp.

pictures of head are small, hard to pick differences from 1.5 to 3hp, but best match is also 3hp. this is actually a very good book with all sorts of info. it is edition specifically for the Wico versions of these motors, you need a book to suit your maggy type.

i have about 3/4 of a 3hp, got a sound hulk off scrap heap about 20 years ago,
bought a few of the add-on bits from other parts collections and the net,
then got distracted by Rotavators.
give me another 10 years and i might get back to it.
my approximate measurements are very close to yours.

great that you have such an almost complete motor, dont rush anything, your parts will turn up eventually, the treasure hunt, fixing and making, is all part of the fun.

cheers Rod.

Re: Rookie with IHC M

the maggy should have a serial number with its ID.
if several other owners of same-maggy-type same model engines could share their maggy serial numbers matched with engine numbers, we could eventually guess an approximate ballpark number / date for this motor.
a 'numbers and letters' game, rusty iron version.

Re: Rookie with IHC M

3hp, Very desirable engine here in the states. Hope you get it going.:wave:
I honesty don't think it'll need much at all to get it running. A good going over and find that rocker arm. They're easy enough to find. If you get stuck I'll ask around for you.
You don't see many of the rotary magneto versions over here either. It is definitely a nice engine to have.

Cheers Scott

Re: Rookie with IHC M

Scotty, that should be the American Bosch S magneto They are quite rare They were introduced in 1923 and ran along with the Wico EK. The Bosch was used until 1932. Without the serial number there not much chance of dating them and If it is not the original mag then that isn't much help either.
The Americans on here will know more about that.

Re: Rookie with IHC M

Hi Guys
Just rolled the engine out to have a better look at the magneto, aluminium cover is a bit weathered. On top I could read American Bosch Magneto Corporation made in USA Springfield Mass. On both the mounting flangs is stamped FX1-ED1 but on the side of the left one is 3473431. Checked the diameter of the shaft again and it is 45mm (1 3/4") so from all your input it must be a 3hp :O
Now for the hunt to find the missing oiler and tube and rocker arm. Will kep you all informed.Cheers Dobbo56

I'll PM a phone number for parts when I get home. It'll probably be tomorrow.
An original oiler will be the hardest thing to find. An original oiler is not required to make it run, and run well.

Cheers Scott
 
Hi i have just finnished a complete rebuild of a 3hp Mtype which yours looks like i purchased all my parts from hit N miss enterprise in america good prices and fast delivery i have converted my maggy as my flick maggy is very sad and no one in WA to rebuild it.

Your engine looks great well done job.
When I get the parts needed and if it goes I will then have to decide if I leave it original or restore like yours
Cheers Dobbo56

Re: Rookie with IHC M

Hi Guys. another easy way to tell the HP of these engines is the bolt centres for holding the fuel tank in position. The 1+1/2hp centres is about 2 inches less than the 3hp. I will measure them and put up on screen later today for your info. cheers John

Re: Rookie with IHC M

I wouldn't spend too muck time trying to date the magneto as it could be a replacement. The engines with that mag were only built for a year +/-, 1923,1924, they were switching to the Wico EK during that time and actually not too many of the engines with the rotary mag were built.

Unless you have different information than I have you are not correct saying that that type of mag was used only for about a year. As I have already posted on this thread, the engines with that mag were built at the same time as the Wico flick mag for about ten years 1922/23 until 1932.
You are correct in saying they are quite rare

Stufforbud If that engine is a 1 1/2 hp gasoline It will be 1922/23 My appologies.

Merv C, stufforbud an others
Thats for all inputs they have been very helpful to a rookie.

Regards the magneto all it has on it is American Bosch Corporation made in Springfield Mass. Part number FX1-ED1 s/n 3473431.
I read an actical in gas engin magazine Sep/Oct and Nov/Dec 1982 by Wayne Grenning tilted IHC type 'M' and I quote from this artical " 1923 as with the 1 1/2 hp M the 3 hp under went similar changes. IHC offered the high tension Americam Bosch magneto, but only 1000 of these were built with this option between the years 1923 and 1932. White metalwas used insread of cast iron for the fuel pump and the needle valve head. Anew caruretor was added, it featured three needle valve, a take apart body and individual chamber drain for gasoline, kerosene and water."
My engine seems like it is a 3hp has a cast iron fuel pump with 90° outlet not the 45° outlet on the white metal one. The carburetor has 2 square nuts to allowing the top to be removed, it also is cast iron with a single drain on the front. It is a three valve unit maked gas, kero and water.
So looks like it is one of the 1000 units built between 1924 and 1932, if nothing has been changed on it after it arrived here in Australia.
Cheers Dobbo56

my brother just found me another Howard, a Bantam.
as it so happens,
right next to it is a good rocker and oiler pipe with oiler base for you.
note: you might have to outbid me for it, im actually still missing a whole head.

spoiler alert:
also contains engine trolleys (some with engines)
also contains a ship tank
probably has that rare bolt you cant find.

follow the links to flickr,
3 pages of pics to scroll down.
M3hp oilerpipe and base = P1130461
M3hp rocker = IMG_3593

cheers Rod.

ps can somebody tell me what make is the big flywheel tractor, side views only?
