Trying to make my WC puller come to life

[AllisWC puller]

I have a allis chalmers wc puller. It has had work done to it but needs more power. What should i do to it in order to make it more competitive. different motor?
 

[BushogPapa]

Gotta tell us what you NEED and what classes you want to pull in..

Ron..
 

[AllisWC puller]

I pull from 3500 up to 4500
it needs more power. Ive been told to find a gleaner motor to go in it but have had no luck at all on that

Put a WD45 engine in it then do mods to it. A WD45 engine is a straight bolt in and will up the HP to around 45HP but not add much weight to it
 

[allischalmerswcpuller]

What do you mean then do monds to it?
 

[old]

The little things like maybe mill the head a tad bit for more compression ad if you really want to ad some semi cheap HP polish the intake and exhaust area of the head
 

[allischalmerswcpuller]

Yea I need all the horsepower i can get

Well a stock WC is right at 30HP so going with a WD45 will bring that up to around 45HP just stock. Now if still want more and have the $$ to play with you could take that tWD45 engine and do an over bore sleeve set, mill the head and maybe do some carb work. If you really want to go hog wild find some one who can port and polish the head for you and that would open it up a good bit more but that also cost your some big $$. A simple polish job one can do with a simple demail type tool and some time

I did mine a few years ago. Email me for some info

if ur running 28'' ruber then a 45 motor is more than enough in relativly stock class, if u want to run larger tires or higher gears the your talking about building a pulling motor
 

[allischalmerswcpuller]

Well it has had some work done to the motor. Ive had some head work done to it, msd ignition. and other things but just not enough power at all. Would a wd45 help out much?
 

[old]

Well as I said the WC is a 30hp tractor and the WD45 a 45HP tractor stock so unless your WC is pushing 45HP yes a WD45 engine would help a lot

Unless it is warped milling a WC/WD/WD45 head will do nothing because the combustion chamber is not in the head on these engines. You can easily upgrade your WC engine to WD45 specs. by using the half inch longer stroke crankshaft from the 45,manifold and carburator. A common cheap trick is to use the WC OR WD flat top pistons with the WD/45 crankshaft to bump up the compression or using 170/175 crater pistons. If you are changing pistons it make sense to go the over-bored 4.125" inch sleeves and pistons. By installing the 45 crank together with the larger bore, your WC goes from 201 cid to 240 cid. Of course you also want to use a governor spring from a D-17, 170, or 175 to get more RPMs from your engine. Good Luck! Kip

What all did you do to your Allis Chalmers
 

[m.appel]

these are flat heads,milling i"snt gonna help,find a e-gleaner engine,if u can"t,thats ok,bore the block to 4.125,use WD pistons,re-grind yor cam to 175 specs,do a good valve job,send the carb to Motec engineering in Indiana,assembly it very carefully,get a part-time job to pay for all this,my wc dynoed about 65 ponies,oh ya,get a 175 gas gov spring,good for 2000rpm"s,your gonna think u died and went to heaven-no BS.
