Dave Ross Where did you get the information about 1650's being shipped with ported hydro's and not equipped with hydraulic lift? Is that documented somewhere?

Some 169"s had the ported hydro and no lift mechanism and that is well documented.

I've always believed, and all documentation I have seen was that all 1450 and 1650's came with ported hydro's and lift mechanisms.

I don't know about 1250's but every one I've seen without a lift mechanism does not have a ported hydro.

Josh O.,
Kohler engines with only the short oil dipstick located on the LH side by the points cover usually indicates that they have balance gears inside the block (unless a previous owner has already removed them). Where as if your Kohler engine only has the long, dipstick on the RH side, behind the starter/generator, then it likely doesn't have the balance gears, since the long dipstick would pass through the same area that would have been occupied by the balance gears inside the block.

Post your 123 data when you get a chance. Thanks!

1) Cub model # (123, 125, etc.)
2) Cub serial #
3) Kohler engine model # (K301A, K321AS, etc.)
4) engine Spec # (4759B, 6099A, etc.)
5) engine serial #
6) Type or # of dipstick tubes (dual tubes, long on RH side, short on LH side)
7) Type of engine data label (sticker or riveted).

Richard C It went across this site sometime in the last 6 months. I think in the last two. the discussion had to do with the only difference between ported hydro internally with hydraulic and without was the relief spring pressure.

Ryan W, Ok thanks! I will try to get the info tomorow. Is there any way to make the engine turn over easier with there being no ACR? mM other 123 had the same problem but only in winter.

Lewis P.,
Thanks for the remaining data!

Josh O.,
Sounds like you have a short somewhere in the system that is draining your battery down.
I'd suggest you disconnect the NEG battery wire when you're not driving it until you can find time to determine what/where the short is and correct it.

I HATE electrical shorts!

Good Luck!

Ryan D, as i stated, There is not a wiring harness on the tractor so i cant be sure which wire goes and comes from where, but i will try

Ok guys, Good night and have a great cub morning tomorow!

Dave,

Richard C. is correct. 1650 and 1450 models all had hyd. lift std. from the factory, optional on the 1250. 149's were all std hyd lift, optional on the 109/129. 169's were a mixed bag and some of them did come with capped ported hydros.

The relif pressure changes only applied to the 169's shipped with out hyd. lift, but ported hydros being converted to hyd. lift in the field. A ported hydro has 2 relief valves and springs had to be switched from one to the other and then a new placed in the lift relief to increase charge pump pressure from ~90-150 psig (non-lift) to ~90-200 psig (lift) and implement lift to ~600 psig. The increase in basic charge pressure by ~50 psig over the non-ported models is presueamably to allow for the additonal restriction added to the system by flowing through the implement lift valve.

I have only ever seen one tractor (that wasn't a 169) shipped from the factory with a plugged ported hydro. That tractor was a late production 682, and I can only assume that they were using up parts they had on hand before moving production to the MTD facility.

Well crap, Now I gotta go find what I was talking about to see what I got wrong.
Richard C, Steve, You guys probly know more about it than I do. Thanks for the post.

My 1650 DOES have a ported hydraulic pump and DOES have the hydraulic lift for the deck, but DOES NOT have the rear sleeve lift. I'm guessing the rear lift was an option?

Josh: I think you have it backwards about the generator. At idle a generator supplies such low current that the tractor with the lights on was probably running on battery. Sounds like you ran the battery low by running the lights and low rpm, then after it died, you tried to start it but the battery was already too low. You jumped it and started driving it back to the shed, probably at a higher rpm, but with the lights on and it died again.

Sounds to me like you have a generator that needs refurbishing, or possibly a short somewhere, draining the battery pretty quickly. I doubt it is a problem with the battery.
