1  Mower Building / Setup Help / Driveline / Re: Craftsman LT1000 won't shift on: October 23, 2014, 10:35:39 AM

   GrubDigger has the right idea.  Chances are, this mower was parked out in the weather at some point, and water/moisture got inside the case, corroding and rusting the shift mechanism, as well as the shift keys, collar and shaft.  Teardown and cleanup are the only way to see exactly how bad it is.

   Remove the shift-detent screw, spring and ball before removing the cover.

2  Mower Building / Setup Help / Driveline / Murray Transaxles? on: October 23, 2014, 10:23:41 AM

   I am trying to compile a list of the transaxles Murray used in their late-model riders -- mid-engine, rear-engine, standard, or wide-body -- anything from 1997 to now.  When you look one up in the Murray Parts Lists, all they show is "Transaxle, Peerless (or Dana / Spicer) -- For Replacement Parts, see the Central Service Distributor in your area."  So...whenever any of you come across a Murray rider with its original transaxle, please note the Model Number of both the Murray and the transaxle, then let me know.  All input greatly appreciated!

   If you're unsure of the date of the mower, most late-model Murrays used Briggs & Stratton engines, so look at the first two digits of the engine Code Number -- that tells the year-of-manufacture of the engine, and that is usually also the year of the mower.

   You can Reply here, PM me, or if you want to call me directly or email me, my Contact information is in my Profile.  And yes, I am interested in hydrostats as well as gear-drive transaxles.  If I can compile a reasonably complete list, I will Post it here.

   Thanks!  Wink

Hi guys, picked up a Peerless 717A 4-speed transmission and everything looks good. But one thing worries me... It sports a 3/8 output shaft with threads on the end. Any ideas or tips? I'm thinking it will be okay, but it'll be hard finding a 3.5" Pulley for it!



   Check out Reply #5 on http://www.heymow.com/index.php?topic=29098.0

   Question: The title of your post says it's an input shaft, but in this question, you state that it's an output shaft.  I presume you're looking for the input shaft...?

  The 600s are obsolete transaxles and are getting extremely hard to get parts for.  Why not flip the 820?  Better, heavier-duty, parts-available transaxle.

  Go to your local airport and get some 100 Octane AvGas.  Much better than normal pump Premium (usually 91 Octane) and no need for mixing.  It's in the $4.50-$5.00/gallon range right now, depending on location.  No ethanol, either...

What's the difference between the two besides they want 200 more for the 140c??

Thanks, boxcar

  The 'C' in the 140C probably denotes copper windings, which would explain the $200 price difference. The plain 140 likely has aluminum-wire windings -- lower cost.  Go with copper.

7  General / Coffee Shop / Returning answering-machine phone call messages on: September 25, 2014, 07:32:05 PM

   Do any of you know a David Cass in Coco Plains, Tennessee?  I'm not even sure on the name and spelling, but if you do know someone close to that name and location, please have him get back to me.

   This afternoon, I received a phone call on my shop answering machine, since I was outside the shop at the time the call came in.  When I checked the messages, "David" wanted to know if I still had the differential locker gears for the Peerless 820 transaxle.  I do, and I pride myself on taking care of my customers, as most of you already know, but at the end of the message, "David" said, "You can call me back on this number."  The only problem is -- he didn't tell me what number, and since I don't have CallerID, I don't have any way of getting back to him.

   When leaving an answering-machine message -- to anyone -- make sure to leave your call-back number.  It's a matter of simple phone courtesy.  And if you have to leave a message, speak clearly and distinctly, especially if you are on a cell phone (my phone is a hard-wire landline), as nothing is more frustrating than having to listen to the same message numerous times to try to decode the scratchy and static-filled message in search of a name and number.

   Go to your local B&S Service Center and have them Sell you a copy of Form MS-0415, Engine/Alternator Replacement Guide.  Very valuable help.

   Then, go to your local boneyard and get a late-model wiring harness off any mower with the carburetor after-fire solenoid. You'll need the part from the instrument panel to the 6-pin engine connector and the carb solenoid -- you won't need any of the interlock-switch or seat-safety wiring.  It wouldn't hurt to get the starter solenoid and its wiring, either, part of which runs off the ignition switch.

   Lastly, get hold of anyone who has purchased a Sears lawn tractor in the last 10 years, and borrow their Repair Parts Manual.  There is an easy-to-follow Wiring Schematic in the front of the Parts Book that shows all the hookups and connections.

   Any business owner will do -- as long as they have a tax-exemption certificate.  It doesn't have to be a mower shop.  Surely someone you know who has access to a tax number would be willing to help?

   "Retail" price on LTH transaxles are in the $600 range.

10  Mower Building / Setup Help / Driveline / Re: Transmission for Senior Design Project (Peerless 820) on: September 22, 2014, 10:55:42 AM
Thanks for the input. As of right now we are planning to run this transaxle.

So multi-person is 8 to 10 pedalers and a driver. With that being said because the driveshaft will have an individual freewheel for each pedaler the input torque will not be equal to the total force of all the pedalers.
   You're most welcome.
   Are you sure you will be able to accomplish this with an end weight of 3,000 lbs.? 

The current plan is to tow this thing in reverse with the rear wheels off the ground for transportation. We will be building a steering lock-in so that we can leave the front axle on the ground and have the transaxle not under any load when being towed.
   Excellent choice for towing, if you are using tapered roller bearings on the front wheel hubs.

Reasonably long service life is honestly probably only a few thousand miles. By taking the static weight load off the axles, and the torsional load of braking off the transmission by running outboard brakes I think this is quite possible.
   I agree.  You may even get more mileage with your planned setup.

Are the gears helical or straight cut? In other words can I reverse drive them? The reason why is, with the current setup I would have to run a 'B' input Peerless 820 which seems to be significantly more difficult to source. With that being said I can run my driveshaft in either direction so if I flip the transaxle and run the input shaft opposite than the standard spinning direction would this cause damage?
   The 820 has straight-cut, heat-treated alloy-steel gears. 
   The only 'B'-Input 820 curently available is the 820-003, which I keep in stock.  However, any 'A'-Input 820 can be converted to a 'B'-Input by replacing the 'A' Cover with a 'B' Cover and reversing the countershaft bevel gear and thrust washers inside.

Lastly, what is the standard direction of input on the 820 'A' and 820 'B'?  Can I run the input shaft in the opposite rotation? Meaning if I flip the transaxle in a way that would usually mean that I would get 1 forward gear and 5 reverse gears, can I just spin my driveshaft the other direction to correct it or will that cause damage?
   The standard input direction for all Peerless transaxles is clockwise when looking down at the input shaft from above the transaxle.  In a low-speed 820 application like yours, I don't see a problem in reversing the input rotation.  Yes, if the transaxle is mounted so that clockwise input-shaft rotation produces 5 Forward speeds and 1 Reverse speed, you will have 5 Reverse speeds and 1 Forward speed with counter-clockwise input-shaft rotation.

Sincerely; Rodney
11  Mower Building / Setup Help / Driveline / Re: Shiftable 700?? on: September 21, 2014, 12:38:25 PM

    Who is this "fellow racer"?  Find out who it is -- he or she would best be able to answer your question.

    Theoretically, it would be possible to shift the 700 while running if you lowered the input-shaft speed, but to do that, you would need a smaller engine pulley, a larger transmission pulley, and a transmission sprocket about the same size as your axle sprocket.  You would also need to declutch before shifting while momentarily backing off the throttle.

Just noticed it said I had to be a dealer with a tax-exempt certificate with them.

   Do you know any local shop owners or business friends there who could order these for you?

13  Mower Building / Setup Help / Garden Tractor Pulling / Re: Panzer model A stocker build. on: September 19, 2014, 01:30:04 PM
   Bob Riordan at Small Engine Distributors in Kansas City, MO, (816-421-6020; www.smallenginedistributors.net ) has a load of old Panzer stuff he will be offering soon.  I believe he's wanting to sell it as a lot.  Four or five complete tractors (one with dual rear wheels), mower parts, ground-engaging attachments, etc.  Sorry I don't have any pictures.

14  Mower Building / Setup Help / Driveline / Re: Transmission for Senior Design Project (Peerless 820) on: September 19, 2014, 12:48:40 PM
We are in the planning stages of a Mechanical Engineering senior design project. We have been tasked to build a multi-person pedal powered bus.

Anyway, I want to run a peerless 820 and I have some questions.

#1) I read somewhere that these things will run upside down (820-017) because they are grease lubricated not oil bathed. Could I run one unmodified rotated 90 degrees backward from the original position. So input shaft pointing torwards rear of vehicle instead of vertically?

   Yes, according to Peerless engineering, you can run these transaxles with the input shaft in a horizontal position.  If you do this and run axle-down, I would recommend that you do as the racers do and also add 6-8 oz. of Lucas Gear Oil Additive to the Bentonite grease to better protect the shift mechanism and cluster gears.

#2) Do I need to run a viscous clutch (slips while engaging until fully engaged) or can I run an on/off electric PTO clutch?

   I suppose you could run either one, although the electric clutch will produce more of a shock load on the transaxle.  My recommendation would be to use a belt/idler clutch, like riding mowers.

#3) Can I shift on the go? Stock lawn tractors usually require you to stop to change gears. However, these 820s seem like they should shift while moving forward if supplied with a clutch.

   You can shift on the go only if you declutch and have the pedalers momentarily stop pedaling to remove the input load on the transaxle.

#4) Will it be strong enough to move 3k lbs with a much slower than average acceleration? Assuming outboard brakes and fully supported (no shear load) on axle shafts?

   That's considerably more maximum load than it was designed for but since it will be a very low-speed input, you should be okay.  The 820 is designed for "ground-engaging attachments", so if you're using one to pull a 2-bottom plow, you're approaching that much of a static load anyway.

#5) If it comes to it (hope to design in a way that doesn't require this) could this transaxle withstand being towed at highway speeds in neutral?

   Only if you want to replace the transaxle after you arrive at your towed-to destination.

#6) Can I run slightly higher than maximum tire size? I am looking at 180/75-13 trailer tires as my smallest option after accomodating brakes.

   Peerless recommends a maximum tire diameter of 23" for the 820.  Your 180/75-13 probably aren't much larger than that.  Again, with the low-speed application of your bus, it should be okay.

#7) Will it have a reasonably long service life?

   Define "reasonably long".  The Peerless 820 is the heaviest-duty gear-drive transaxle available, so it's the best choice for this project going in.  The only way to find out is to build it and see how it performs.

Sorry, that is a lot of questions. Some of these things I will have to do analysis on to prove them to my sponsor but if it isn't going to work I don't want to waste my time on it. Especially, because I have not been able to get a response from Peerless about the load specifications of the transmission.

Thanks, A lot.  

   Apology not necessary.  "You won't learn if you don't ask."  If your sponsor wishes to contact me, that's fine.  And if you need further questions answered, feel free to email me.  I've helped with mini-bajas in the past.   And...you're most welcome.  If you do go ahead with this, you'll have to let us know how it works out.

   Your only other choice would be to use a transaxle from a small FWD car, but that would be considerably heavier than the 820.

   My question:  How many people is "multi-person" -- how many pedalers are you planning to have powering this 820-in-a-bus?

   http://www.smallenginedistributors.net/transaxles.html .  Buy a supply of the 2000-002 or 2000-007 if replacement is required in the future.  These Peerless LTH 2000-Series transaxles are good units.
