Transmission chatter at idle
This topic has 1 reply, has 2 voices, and was last updated by
7 years ago October 10, 2017 at 2:47 pm I have boat with two Iveco AiIfo Turbo Diesel engines 8061SRM30.10 and ZF IRM220A transmissions. Starboard engine and transmission run smooth, coupling between engine and transmission is Vulkan Torfles KT3. Poert size features Vulkan coupling that is actually just rubber disc between two mating parts. This engine and transmission chatters at idle. I asked every one, ZF, Iveco, marine places and no one knew why chatter occurs. I increased idle, c…

Twin Disk 5050SC temp and pressure senders
This topic has 1 reply, has 2 voices, and was last updated by
7 years ago October 6, 2017 at 8:39 am My boat has a Twin Disk transmission 5050SC connected to a Cummins 6BTA 5.9 370HP engine. The instruments harness has wires for a transmission pressure and temperature senders but the senders were never installed. Does anyone know what temperature and pressure sensors should be installed and where they are connected to the transmission? The information will be connected to a NEMA2000 analog to digital converter for display on a multifunction dis…

As to Twin Disc support–What you have found out is why I try and stay away.. Very poor support overall… I wish I had a better answer.. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Just took a chance with GOOGLE..

Transmission removal and replacement.
This topic has 5 replies, has 3 voices, and was last updated by
7 years ago August 24, 2017 at 5:24 am Hi all, The transmission went on the port engine of my 31′ Bertram, roughly 6 weeks ago and I have been unable to find anybody even interested in replacing it. The engine is a Cummins 4BTA (serial number 46043905), and the best I can tell the transmission is a Twin-Disc 5011A / 1.44:1. I am getting the transmission information from the starboard engine because the data plate on the port engine is missing. (see attached pictures). Also I am…

Now for the odd but good news: I went into the local Marine store here in Cape May to buy some penetrating oil, and ran into an old timer who asked me what I was using it for. I explained what had happened, and he said, “take off the mushroom cap and then try it”. Further he said it sounds like the …Last Post by:

Vulcan coupling life

7 years ago August 26, 2017 at 10:30 pm Hi All, I just left a vessel that has developed a gear oil leak on the main input shaft as it is dripping out the drain on the flywheel housing. It is MG 5114a with 100 hours from rebuild, the gear box has other issues . I don’t trust it and it think it needs to come out fp. All that being said they are still working the vessel 12 hours a day and have a 750nm steam back in 2 weeks. With all the oil on the silicone vulcan coupling how lon…

ZF63A gear fluid change, stay with ATF or switch to 15-40 oil ?
This topic has 4 replies, has 5 voices, and was last updated by
7 years ago August 15, 2017 at 7:09 am Hello All, I’m about to do a fluid/filter change on the ZF63A gear coupled to the 6BTA 370 in my lobster boat. There’s been lots of discussion on other forums on whether to run ATF in the 63A gear as listed by ZF……..or…..switch to 15-40 oil that is also approved by ZF in the 63A gear. The change from ATF to 15w-40w oil supposedly “quiets” the gear rattle and shift banging. Anyone have any thoughts or opi…

ZF 220A inspection
This topic has 7 replies, has 3 voices, and was last updated by
7 years ago July 23, 2017 at 7:51 am I have a ZF gear on my 6bta 370 with about 3500 hours. I am not having any problems other than gear whine that has been there since I got the boat (1,000 hrs). I cannot afford mid season breakdowns and I am curious if it would be good to remove the transmission and have it inspected during my off season.

ZF 220A Hard To Shift Out Of Forward
This topic has 1 reply, has 2 voices, and was last updated by
7 years ago June 29, 2017 at 5:57 pm At idle speed, I can shift easily between forward, reverse and neutral. After taking the boat out and running, my port transmission requires a fair amount of force to move from forward to neutral. After the initial popping feel when enough force is applied, the shifter moves easily into neutral. Once in neutral at idle speed, the transmission once again moves easily in and out of all positions. The oil level is good and the oil looks clear …
1 ReplyJune 30, 2017 at 5:17 am Have you disconnected the cable at the tranny and verified it is not a lever/cable issue? Once confirmed it is not a lever/cable issue investigate the shift valve for marine age. Post some pictures of your engines/gear and specific pics of your gear shift lever.

7 years ago May 30, 2017 at 10:45 am In the below picture, is the port which I would use for oil pressure monitoring during trolling valve operation circled in red correct? I assume I am looking to monitor the oil pressure to the clutch plates? And if this is the correct port is it a 1/8 NPT or some other thread? What would be the operating max pressure I would see and what rating hose should I use?

Gear oil for Hurth HSW 800 V1 (ZF)
This topic has 2 replies, has 2 voices, and was last updated by
7 years ago May 30, 2017 at 11:14 pm Hi all, Simple question. I have two Hurth HSW 800 V1 (pre ZF), 1.6 ratio. Which oil is preferred ? Oil is a jungle and manual I have is for the later ZF versions stating just Dexron II or III. I can get the “Castrol Transmax Dex III multivehicle” for a good price. Is this a preferred oil for this gearbox ?

1 ReplyMay 26, 2017 at 7:58 am If you prop ( impeller) your engine to make the governor break point of about 2890 RPM, then the ZF220 will give you good long term service and to its HP & torque capabilities even in heavy duty high annual hour service..
