Default 1959 David Bradley Sears Suburban

Does anyone have a riding tractor from 59 or 60 That has an electric start? The tractor has a Sears number of 917.60602. I have the manual but it does not show the belt info for the starter. It has a Briggs 143402 5 3/4 hp engine. Neither the Briggs nor the Sears manuals offer any help.

If anybody has either the belt number or the part number I'd really appreciate the information.
Thanks,
Alan

I assume you have a starter/generator system. Most were 3/8 inch wide belt. I do not have a part number for you. What you need to do is measure the length of belt you need. You can do this by taking a old worn out belt and cutting it into. Then with the adjustment on the generator near the bottom of the slot wrap this cut belt around the pully and mark where the one cut end meets the belt after you have fullywrap the belt around the pulleys. Then use a tape measure to measure the length you have marked. Use this measurement as a starting point on the belt length you need. Most likey you will not be able to buy the exact length you have measured. get a couple of belts , one shorter and one longer, than what you measure and see if you can make one of them work. When you find one that will work, write the part number on the engine shroud for future referance.

Kent,
Thanks for the reply, but no generator. Just a starter. This does not take a 3/8 belt. The starter pulley is much smaller. When I put the 3/8 belt on, it jams against the guides. It looks as if the starter pulley is only about a quarater inch. There is no idler, so the belt runs all the time.
I appreciate your input.
Alan

If it is belt driven it is most likely a starter/generator. Could you post a picture. I have a Clinton powered Worthington 2 stage air compressor of about the same vintage with a stater/genertor.

Kent, I don't know if these will help or not. The starter has only one lug, and that is for the battery pos.
Thanks again,
Alan

could it be that the crank pulley has a one way clutch? the drive ratio would result in a very fast running starter otherwise, looks like close to 6 or so to one equals over 20000 starter RPM at full throttle??

That is a really good point Lloyd, but the pulley bolts directly to the flywheel. No clutch.
Thanks ,

Well everyone, time to wipe the egg off my face. I also found the part number on the Briggs web site and then went looking. It is a 3/8 by 30 according to Carquest. Brought it home and the 3/8 is ok, but I need a 28 or 29. I found some adjustment space where the starter attaches to the shroud, but can't move it far enough to tighten the belt. I am hoping the smaller the belt the less binding I will have on the belt guides since I can move the starter pulley closer to the engine.

Again, thanks to all who tried to help an old Dutchman with blurred "vision".
Alan

I have a Suburban in Central VA to sell. It is missing the grill and hood and has the wrong engine, but includes mower deck. Was running and moving until the belt broke last summer.

The 1959 Sears DB Suburbans had an electric start option it was a starter only not a starter /generator when you purchased the starter option you got a trickle charger with it to charge the battery. There is no one way clutch the starter ran all the time like a starter / generator.

Actaully no. The starter has two pulley halves that slide and lock to start the engine, but once the engine spins faster than the starter, the back half of the pulley disengages and the starter quits spinning. Kind of like a hand crank engine.

Hi IWL BCNU, thanks for that information I did not know about the pulley clutch as the ones I've seen only had a solid pulley but after 50 some yrs things get changed.

Probably rusted in place. I'll have to look at mine to remember exactly, but the outer half is held in by a pin, and the inner half is supposed to slide. IIRC it has two slides or ramps and when the starter spins it makes the pulley half slide outwards and grab the belt, but when the engine takes off it overspeeds the pulley and makes the back side back off.
I doubt it is good for that small motor to spin engine speed all the time.

After searching the web and buying Allens 59 bradley for the starter he had rebuilt. I figured out how this thing works. Allens bradley was far nicer then what I had. So I installed my parts on his tractor. The starter works like it should.

It works like a snow mobile clutch. The rear half of the starter pulley comes out against the front half and tightens the belt. Once the engine starts the belt pulls the rear half of the pulley down off of the ramps and loosens the belt. This alows the engine to run without turning the starter. Allen was missing the 2 small pullies which makes the belt wrap farther around the drive pulley and create traction on the drive pully.

I bought five 59 bradley's to get all nice parts to do a nut and bolt resto. Now I have everything I need. Thanks for the tractor Allen. By far the nicest of the five. Steve

One will be over restored. all bolts cadium plated and assembled after paint then cleared . one will be back to original assembled then painted gold. The over restored will be electric start and a keeper. The original will be a pull start and sold or raffled.
