Default New 1811 Frame Twisted















I just brought this home to replace a 1512 I just sold. It has only 711 hours on it. The 1512 had a bazillion hours on it but I probably should have kept it. I didn't notice how twisted the frame on this 1811 was when I bought it. It has a bad bearing on the 44" deck (center) because the grease zirk is plugged.

The fluids are clean and I got the push blade with it. It runs good but there is fuel leaking slightly from the carb float bowl. The throttle/governor springs must be in the wrong holes because the throttle isn't right.

Any advice on measuring and straightening the frame? Once I can verify it is tweaked, my plan is to use a come-a-long and a couple of oak trees. I'll pull the right rear while the front left is anchored.

The tractor in the rear is an 1864.

Before you get crazy, loosen the six bolts that hold the transmission in the frame. You would be surprised how flexible a Cub frame is. Ask me how I know.

I don't have a pic but I had a 1772 on my lift table and noticed that it was twisted to the muffler side and I was positive that the frame was twisted. I loosened up the bolts that hold the rear in the frame, jacked up the muffler side and re-tightened the rear-end bolts problem solved. On the 82 and 72 series Cubs the rear-end is a stressed member. That's one of the reasons they bust the aluminum rears at the front mounting points. As absurd as it sounds just the weight of the muffler on the Kubota powered tractors because it hangs off the right side is enough to cause this after enough time with loose bolts in the rear. The Supers are the worst because they have longer frames.

When you get it straightened out you can bolt in the rear plate off a cyclops and it will really stiffen it up.

Sam,
I shouldn't have used the word, "twisted".
Maybe this is better: I think the left side of the frame is pulled back.
The 1512 I had was really loose compared to this 1811. The hydro on the 1811 is pretty noisy. Maybe the rear end is a little tweaked? Another symptom is that when the brake is pressed all the way to the foot board, the hydro lever isn't centered, it is slightly in reverse.

I still plan to replace the fluid and filter.

I spent the night loosening and lubing tensioner pulleys on the deck and hanger.

RR1862CC,
I need the plate to mount bagger. I agree, it is a good add-on. Thanks for sharing the insight. I already bought one on eBay.

Looking at the pics I can see how you would think it has diamond frame damage, however I'm more inclined to think it's a bent dash and misaligned grille housing. The amount of frame damage it would take to make it look that bad would probably rip the bolts out of the rear end housing. You could mesure it diagonally just to be sure.

I put a square to the frame this morning before work. The left side is about 5/32" forward of the right side. That's exactly opposite of what I thought I'd find. The 1864 reads square at the same points.

I'll square everything up when the rear plate arrives, or I'll just steal the one off of the 1864. It'll be interesting to see if moving the frame changes the brake centering.

Some advice needed: I suspect the six bolts are in there with locktite. I loosened all of them a 3/4 to 1 1/2 turns and the frame didn't budge. I've turned a lot of wrenches in my day and I didn't like the feeling I was getting from the bolts, especially the four in the differential housing. They did tighten down again.

I was thinking someone had loosened them before and then over tightened them. Should I be using the impact to loosen them? If you use heat, how long do you apply heat and where do you apply the heat.

Thanks!
PeterJ

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
