ZF 220 housing crack
This topic has 2 replies, has 2 voices, and was last updated by
April 23, 2024 at 6:56 pm ZF 220 A gearboxes were pulled apart for bearing and seal replacement while the engines were rebuilt and an internal crack was noted in one of the housings, refer attached photos. It appears that the crack has propagated from a pilot pressure hole, does anyone have a flow diagram for the ZF 220 so I can figure out what caused the crack. I am thinking of using a rotary burr to open up the crack and TIG welding it back together then redrilling the…

March 25, 2024 at 7:38 am If the tag is missing from my transmission, how would someone tell what model V-Drive I have. Ā It is bolted to the following spec Cummins.Ā Model: 6BTA5.9.M2 Serial:4483T453 HP: 300HP Is there a certain profile.

February 29, 2024 at 12:29 pm Hello, does anyone know the correct part number for a Hurth HSW 630V1 trolling valve? (behind a 6BTA-M2-250HP) I understand ZF 63 is a similar transmission which I have found trolling valve part number ZF 331299009, can anyone confirm if that is compatible with my transmissions?
1 ReplyMarch 1, 2024 at 4:44 pm For anyone else that is wondering I have confirmed with ZF that Part – 331299009 is indeed the correct part for the Hurth 630V1 and ZF 63IV transmissions.Last Post by:

It was working normally, until one of the hydraulic lines to the oil cooler (rusted at the coupling) and leaked the fluid out. At which point I had no forward or reverse. I replaced the hose, filter and refilled and now I have reverse but no forward. When in neutral the shaft …

5 months ago November 24, 2023 at 6:32 pm Good evening, I am in the process of powering a boat with a qsm11, currently the boat has a man D2876LE401 with a twin disc MG514c gear. Was wondering if there is a bell housing to join the twin disc with the qsm11?
