Have problems with my 1650. Trans not engaging.

[joetx]

Thanks in advance for any help you can give me. I'm new to the cub thing, but I have managed to get a hold of three. A 1650, and maybe two 124's. Had one abandoned at the shop for maybe 25 yrs. and finally started working on it. Meantime, I traded for the 1650 and then a friend gave me another 124. Got this 1650 about 6 month ago. Finally got it to run and I parked it to wait until I got some implements to do some gardening.

Got everything ready and now my tractor is not moving. However the implements do lift. Checked the oil and it was really low. Added little more than a gallon. I just wanted to top it off to see if it would work. Will change all fluid and filter later.

Started it and worked the forward control valve forward and reverse and it finally moved forward. A little jerky, but that seems to have stopped. No reverse. I ran it around the yard a while and checked oil once more. Topped it off again. Moves forward but no reverse. After messing with the lever some more it sometime goes into reverse, but very slow and in a jerking motion. There's a 2" hump to get into the shop and it wouldn't reverse over it. No power at all.

The forward movement isn't great either, and I sometimes have to move the lever from forward to reverse and back until it "catches" and goes forward.It doesn't have power. Seems to have a lot of slop in the bracket that actuates the pump to make it go in gear. It stays in neutral and doesn't crawl.

I saw on youtube how to adjust so it stays in neutral, Don't think that's my problem. Anyone have one taken apart, where you could send me or post some pictures of how the brackets are supposed to look when they are in good shape...New condition, so I can compare to mine.

Here's my 1650

I would change the filter. I didn't think it was possible for a filter to be so gunked up that the hydro wouldn't work, until a new to me 1811 would jump about 1o feet, stop, repeat--etc. Installed a used filter of a junk rear and problem went away. Of course I had a trans. full of water too. Changed oil and filter and hydro works great. I would spend $15 on a filter if it were mine.

As it happens, my wife has a Dr's appointment tomorrow and I'll be where there may be a cub parts place. I live out in the boondocks and have nothing here. I thought about buying a filter and gasket if I can find them.

Another problem, is the brake/clutch pedal? Don't know what it is, have a return spring. Mine seems to stay partially down and doesn't return completely. Anyone have a parts # for a spring if needed? Thanks, Joe.

It is a brake pedal. It also puts the transmission in neutral when depressed. It does have a return spring. It could be either 3 or 7 inches long. Probably dependent on serial number. Look underneath. It may be broken or disconnected. Maybe bungee cord it all the way up and see if that changes anything.

Search the forum, maybe the resource section,--I am pretty certain there is a list of acceptable filters you can pick up at a parts house. Check the list--just because the filter screws on doesn't mean it will work.

Regarding your spring and filter too, just go to Cadet's website and look up the parts--you can even buy direct from Cadet. There are some of our sponsors that carry a good selection of parts as well.

Think I took this picture of the serial number.

X10 on fluid and filter. You can't troubleshoot a hydraulic trans until you know it has good fluid and filter. It's "Step 1).

Wix 51410, Napa 1410.

Here's the official list of filters that cross:

Long shot, but if someone was monkeying around and removed the charge pump and did not install correctly since it can be done, will not produce hyd. pressure. The pump swash plate is what's going to be giving you your forward and reverse inside the unit.

If the charge pump was on backwards, the lift wouldn't work, and the unit would not move at all.

Makes good sense, Jon! I wondered if that mistake was absolute zero pressure, since the engine would still be turning the charge pump. Good to know!
