The fast classes will soon be a all 460-560 show. They have just started to develop the RD engine, combined with the torque-amphlifier, no contest.

so all of your clubs run stock engines? why the constant bashing of rd engines? why the constant whinning? im always hearing this argument n get sick of it, where were u when wackashaws entered,or dt466, or combine motors or so on and so on. all clubs offer stock pulling, all clubs have rules n if ,like u say they make a class for the non ag engines then fine itl be their rule, but id say all ag classes alta run stock weight

a stronge m will run with a rd at lower spd limits, ive seen it all summer, same for a olli ,but a wackashaw is same problem as a rd, not really a antique engine, if everyone bashing a rd would say only able to run a engine pre 1959 it be same as 20 yrs ago ,oh but then ud be sayn it aint fair a guy can build a 30k plus m engine so a rd with big cubes n a lower spd class all light is behind the eight ball but yea a real beaste in fast or open. jm2cnts

The RD engines, except for the 501, date back to at least 1950...for those who say it's "modern." IH stayed with it a long time, but its origin is fairly ancient.

I was aware of the rd ag being a true antique but the real point was why bash the rd n not the others. Jmho if guy bashing wants some other ideas just ask, lots of ideas about rules to make things fair but none will fix all

Red Diamond (RD) engines date back to 1940-41.

They are the factory replacement engines for the

FBB engine series. The FBB came in W40/WK40 tractors

so RD's are an ag engine. IIRC the RD501 was

introduced in 1954,1975 being the last year of

RD production.

Oh my. Let me try to straighten things out a bit. I'm try to find out about transmission and mostly rear end issues.

Just to clear up things also, this tractor will be an antique V-8. I will be doing a lot of what I call "standard practices" to improve the strength of the components. The HP. applied will be aprox. 750 to 850.

My apology for not being a little more clear.

560 rears with all improved parts installed in the transmission and rear are the strongest. They put in a stronger differential with tapered bearings to support it. Different bull pinion gears with bigger support bearing. Bull gears also with a different tooth angle. Then they started offering a roller inner axle bearing and a roller bearing to support the rear of the transmission main shaft. Also after a serial number break the rear main shaft bearing housing along with the transmission housing was changed from 3 bolt to 4 bolt support like a 660. 400 and 450 rears are much like a 560 so some parts interchange. Between SMTA to 450 W and F models and all the 560 models and the 660 several different transmission gear speeds and ring and pinion combinations can be used. F-560 has a deeper reduction R&P than the SMTA to F-450. Also standard first was deeper on a F-560. High speed 1&R on a F-560 was the same as SMTA to 450. 3rd and 4th gears also have more than one choice. Like someone said if using a T/A and depending on if shifting more than once a pull, at least the T/A clutch needs beefed up and the rest in top condition. Don't know about some of the beefed up T/A units, get conflicting reports. from the rear of engine back a SMTA to 560 is the same. If I remember correct that's 5 inches longer than a M for the same distance.

it would be closer if it was a 400 or 450 vs 560 chassis....then a M....the 400/450 are 4 inches longer than a M plus have ta's just like a 560....either way you will have to buy a heavy duty ta that can take it if you know what I mean and a heavy duty clutch the rear end weather 560 or m 400/450 send out rear gears and get a good limited slip to make it pull better. gears and stuff in rear are strong in both tractors.....hope this helps im not getting into the other motor stuff they did enough of that in other posts I know your going v8.....

560 transmission/rear end has more parts available

for what you have in mind. If possible a 656 rear

is better still. is a good place

to start asking questions, 750-850 hp is entry level

over there. lol. Good luck and have fun.
