It would be pretty difficult to put a FEL on a dozer that had never had one on it from the factory (not saying it’s impossible though) The towers (transom weldment) are totally different, wider, and have two additional pivot pins per side. The FEL is model number GU306, and I suspect it is manufactured by Guilin but not positive.
The lifting capacity on mine is probably around 1,800 lbs. and I say that because I’ve had it full of very wet gravel with no problem.
Another thing you have to consider is the rear counterweight that attaches to the TPH. It weighs about 1,000 lbs. and is very necessary to keep you from going over on your nose when lifting heavy (I just used the backhoe instead). Did you see my video of the FEL in action?
I haven't used the FEL at all since I purchased the skid steer.

Now I get it. You have a manual shuttle clutch, like that found on a wheeled tractor
Those pics sure bring back memories. Had many Cats down to the bone like that.
You're doing a great job. And btw, i found the OEM joy-stick hydraulic valve stack from my dozer if you're still interested.

Like, what would happen if the pulley was on the break arm instead of the pedal?
Then the take up rate would be about one-half that of the OEM rod linkage, giving no advantage in this case. It's explained pretty well in your link.

Some additional questions Bob:
How do you plan to adjust for brake wear?
There is no real adjustment for that per se, but the pedal travel is adjusted by taking up on the eye bolt.
How did you make sure the steering clutch was open before brake was applied?
Actually, I didn't touch the clutch adjustment, it was still within spec. It still fully releases after about 1-1/2″ to 2″ of pedal travel, at which time all of the slack is out of the brake band and it is being applied from that point on at 2x the normal rate, so you actually have less pedal travel to achieve full braking capacity.
Unrelated to mod….How did you adjust your steering clutch?
By the book.
Bob, I think you can start wearing your cape.
At no point did I say we have reached the promised land, and I have no idea why I insist on calling you Pete. Account deleted.
Thanks guys.
Pete,
There are more forces involved than a simple class 2 pulley system. The movable pulley anchor point is about 3″ up from the pivot (fulcrum for the second class 1 lever system) point. The distance from the pulley anchor point is over a foot. There is a tremendous mechanical advantage there that overcomes any losses in the pulley system. In essence, the pulley system efficiency is compounded.
Hope that explanation works.

Correct.
“The geometry configuration of the cable allows for twice the take up rate of the brake actuating arm over the straight rod linkage…”
Nothing was broken.

Here is the pic of the mod. The geometry configuration of the cable allows for twice the take up rate of the brake actuating arm over the straight rod linkage, compensating for the slack in the actuating links at the brake band anchor points (and it feels like power brakes too).

Agreed. However, I would make absolutely sure that coolant isn't trickling down from another source, such as the thermostat housing.
