PULLEY HELP

Damn... I did this once. I hate to say it but I had to start over. Mine was really off center. How far is it off? if it was less then a quater inch I wouldn't worry too much about it. Unless you want it to be perfect. Probably the worst thing that would happen is the clutch might chatter a little bit when engaged.

This is where welding sucks!! lol

with a 6" up front, that thing is gonna fly! I'd try to get atleast a 5" in the rear. But thats my presonal preferance. I guess it depends on what your gonna do with it. If your JUST mudding, then fast is fine. I like having a slow first gear for steep hills, towing, rockcrawling, or just going slow over big bumps. It makes it more of an "all purpose" rig.
The murray used to be alot faster... It was too scary to drive on anything other then a smooth surface. I had to slow it way down to wheel.

I don't know about that one, maybe dangorustoys can chime in. Are you gonna double up the spiders or weld it up?

hey chunk, ive seen those trannys before. I had a tractor and it had the heavy duty gear oil inside her. The guy that i bought it from said that the tractor was made for a lawn service company and it was specialy made. It had the greese fittings and everithing. But someone might have done that them selves, you never know.

about your pulley, witch way is it off center? You probably dont have Canadian tire but they sell all the pulleys and belts and the pulleys ate like $5.00 can. and the belt are like 10 or 15.00 can. I dont know if it would be worth shipping over but watever.

hey we run a 5" on 5" on our off road mowers it seems to work the best good low end and nice top end we order our pulleys from www.phoenix-mfg.com/

Chunk: I hate to say it too- id cut it off n start over- itll be spinning pretty good and it might throw the belt. i got lucky when i welded mine- the guy had the splined adapter - all i had to do was weld it on the flat deck pulley - tacked it a few times, kept checking it and then welded it up good.

Fearlessfront: Ive seen a couple transmissions with gear oil - one is in my 82 ( thought it was an 84) dynamark - has a drain and fill plug - ironically i have a spare trans exactally like it off a 70's simplicity.

The other kind ive seen is a peerless 700 ( lower input side output kind)- has oil in it, murray transmissions also can use oil - the one in my 94 murray has a fill hole under the pulley .


As for stock grease fittings on a transmission/axle shafts? Never seen one in the 15 years ive tinkered with tractors.

On my mod murray i used a 6" motor and a 3" trans pulley - that thing would go scarey fast - had it in 4th of the 6 gears and almost flipped it when i hit a bump in the road.

My Deere's top end is around 12 to 15 mph. I had it up to 25 mph it was unstable so I slowed it down I run a 5 inch on a 5 inch. The Deere is for extreme off roading not racing. We trailer our mowers to the trails.

Hi
I am new to all of this but i watch alot of videos chunk and i was just wondering i want to restore a mower but also make it in to a racing onee.
Soo what size pulleys would be the best for speeed..
Cheeers

Changing pulleys isnt the only mod youll need to do for fast applications- youll need : direct steering ( stock steering wont work- ive had first hand experience) , lowering the machine/widening the stance , high performance brakes AND saftey gear - like a helmit.

I went upwards of 30mph on my murray and nearly crashed - i took that tractor apart to redo it sometime, but in the meantime I built a MTD thats lowered and pretty quick and handles tons better .

Unfortunaly, you cant have a restored AND fast machine. THere'll have ot be some comprimise somewhere, either in the speed or restoration.

Most of the off road tractors on here dont need direct steering because none really go over 15mph. If you want to go fast, you'll need to upgrade the brakes, and fill the gear box with oil instead of that lovely benodite grease But with a stock tractor, you'll want a lower centre of gravity, so the seat being lowered will help alot.

If you want to keep a restored tractor but have it a little fast I'd say a 1:1 ratio at the most would be ideal. Still plenty of pulling power, and a nice top speed to go crusiing with. What kind of tractor is it anyway?

I have a 12'' on the front and a 6'' on the rear it tops out at about 45mph don't forget the brakes and locking the front stearing. check out the Dynamark racing mower by me that is my build.
