| Hey new here just looking for some advice on my WD I use for planting and most of my hay work with. Wondering what could be done for more performance for in the field. Been considering putting pertronix in and wondering what I could do to the carb? Thanks in advance for any input on this. |

How much more do you need? Haying and planting aren't really high horsepower applications. WD45 crank and pistons will buy you about 10 horse. Gleaner E or D17 engine would gain you 15 or so. Keystone turbo will get you 15 to maybe 20 more. Best option is sell the WD and buy a D17. Far better tractor anyway. AaronSEIA

| I’ve thought of going the d17 way but I hate to get shed of my WD first tractor I bought plus just refreshed the motor last winter. I pull a international cyclo and would just like a little more for on the hills to keep the air up and keep my speed good. The haying isn’t too bad but my 9 foot haybine in heavy stuff you can tell it sure wouldn’t hurt to have a little extra. |

| Perform a cranking compression test on that engine with the throttle wide open and a battery charger on the battery. Report back with the results and we'll go from there. A WD normally has 100 lbs compression. A WD45 has 125 psi. A D-17 has 145 psi. A WD45 carb, manifold and air cleaner will wake it up some. |

| The tractor originally was a wd45 and had terrible over heating issues even when taking hay and I got frustrated brought it in and tore it down to find a cracked block which I had the old WD motor sitting at home and after I rebuilt it i used the 45 carb and manifolds. And me and my dad tried our best fine tuning the carb. |

| But, you might have considered using the WD45 crankshaft in your WD engine when rebuilding it. You've gone backwards in cubic inches. |

| Would that work with the flat top WD pistons? |

| Run a compression test FIRST !! If they are old pistons/sleeves you cannot install the WD45 crankshaft because it will push the pistons right up thru the ridge edge worn into the sleeves. |

I've cut the ridge out before. Have a ridge cutter somewhere in the shop. ------------- -- --- .... .- -- -- .- -.. / .-- .- ... / .- / -- ..- .-. -.. . .-. .. -. --. / -.-. .... .. .-.. -.. / .-. .- .--. .. ... - Wink I am a Russian Bot |

| I wouldn't ever consider using a sleeve that had the ridge cut out just to accommodate the 4 1/2" stroke crankshaft. It needs new sleeves at a minimum. But, until he runs a compression test, we don't even know how high his compression ratio currently is. |

| I’ll do the compression test first. Once I find out compression tester first that is lol |
