I would go watch the 55000lb antique class!!! I know they used to do such things here but that was 40+ years ago, are there any ultra heavy antique pulls anymore?

Maybe your stroke is too long for your sleeve and the piston is coming too far out of the bottom of the sleeve at the bottom of the stroke then it is trying to cock in the bore to shove back up and this causes excessive heat and failure. I have seen that before.

A perma clutch will likely not be successfully setup by fooling with finger heights. You need the proper tool which indexes off the cover plate and actually clamps the clutch with pressure like it was applied so you can set the fingers. There are 2 different pitons sizes used on 4430 depending on SN and the shims used on the tool are different. A perma clutch is not like a normal clutch since it

Makes sense to me $10K on a turbo is totally fine but a $1500 head is just out of line!!!

Lots of dimensions wrong to put IH sleeve in Deere block. Why not just bore the 1/16in out of the Deere liner? Be much easier.

Do you have a print or sample of what you need? I have made several one off shafts for pullers.

.050" is a pretty standard desired clearance on moving parts.

4955/4960 has the low ring piston and 9mm is the old injector size so you need a drill slightly over that.

Going to need a 9.0L block though for a 7 journal Deere cam unless some serious machine work and fabrication is involved.

Because of the extreme amount of flex in the Deere cam I would advise against putting roller bearings in the block as they will likely spit themselves out.

Fracture split and Powder rods are not always the same thing. There are forged fracture rods as well. All the common rail Cummins engines left the factory with fractured rods and there are plenty of them over 1000hp on stock rods. Deere has been using fractured rods for around 10years as well and I know of a 9.0L motor running 1600+hp and over 3000ftlb on stock fractured rods.

I am not sure what you are getting at here. The old rule was not effective at all and the class was running a lot of 4.1" turbos with a 3" ring hanging in front. The new rule is 3.6 smooth bore which is probably actually taking power away from the class. I actually think that they should just go ahead and make it a prostock class and allow any single turbo, then the cross competition would be a l

Intercooler, it works better and is more reliable. They also act as a filter for the engine if you pop a turbo. I far prefer being able to shake turbo bits out of an intercooler rather than having to pull a cylinder head and fish them out of pistons and probably even having damaged valves and seats.

If you change it to 3000rpm limit then they might as well just be Ky hot farms as there really would be no competitive difference besides turbo and a lack of safety equipment. With the current turbos the limits of the factory drivetrain is already an issue as I know several have broken this year. As the class currently is you already could build a hot farm for the money it takes to have a competi

The diesels better enjoy it while they can. I imagine the alkys will be voting the diesels to 3" smooth bore next year.

I built a 4640 rear end tractor that can get down to 8500. It was a serious diet. Aluminum wheels, home made frame and front end, roll cage and lightened everything. Drivetrain is very strong though. Still has factory brakes though so it could still drop several hundred pounds if it needed to but it runs in a 10K class so no need, plenty of moveable weight now.

48% faster. If you have the power for them you will just end up breaking your trans as they add a lot of load by changing the reduction from the finals to the trans itself.

You won't make any power at 6000rpm with a 3x3 turbo. Power will be dropping after 4000rpm for sure with that setup. You will probably be around 800cc, .093 lines should be good, just get the biggest good intercooler you can find and forget about the water and meth.

Piston pins are moved up in the piston, that is how it handles the extra stroke. Main bearings are bigger diameter in 8.1 vs 7.6 as well.

Under 850 hp a beefed up quad range clutch and 2 spd should hold good, over 850hp and you will start wrecking gears and the stub shaft between 2spd and transmission.

Nobody ever offered a 903 in a 2wd, so any class you can run it in you should be able to run a 8955 too. Then again I think this is all silly and the top level classes should just be cube limited and whatever turbo limits and the rest should be open, I mean after all how many of the parts in one of these were ever available form the factory? Very few if any, there are Hypermax motors that don

There were aftermarket kits available to put 8v-71 in the big Deere 2wds and Cummins made a kit to put 903's in them as well. I would be interested in building an 8955, but I suspect it to be a learning curve for sure to get it right. They had a bit of trouble with reliability in stock form so not sure how it would do once you really started leaning on it. I figure some diehard Deere guy wo
