I have removed the engine for repair and have noticed that universal joint has small deterioration. I should change it? And where to buy spiders 6598303 and 6598304? In a manual parts they have different numbers, they differ? There are no problems in replacement? It is necessary to balance? I am sorry for English, this is mine Google the translator.

6598303 and 6598304 different?
Yes they are both different. One has threaded tabs for the allen bolts to screw into, the other does not. When you remove them, you will see they are slightly different.

Notice where the grease zerk is, some are in the middle cross and some are out on a end cap which makes it easier to grease in the future.

The u-joints for a 642B are Precision U-Joint 994 (PRE-994) and Precision U-Joint 952 (PRE-952). I bought mine from Woody's Auto Supply online. They're about $45 each. I think the 743 uses the same U-joints.

Grease zerk on Precision U-Джойнт 994 (PRE-994) and Precision U-Джойнт 952 (PRE-952) are in the center, it will be not convenient to grease It.

Unfortunately, I can't call, therefore have written the letter in Loader Parts Source but while there is no answer. Somebody from Loader Parts Source can will read this branch of a forum. Question: whether there is a second spider and where there is a greasing place.

Have you checked with Bobcat for parts? To get what I wanted for the 632 I had to go to Bobcat , theirs were a little higher but not much and they greased on the end cap.

My the nearest in 350 km and not so (I so have understood) wants to potter with old cheap spare parts.
