HSW-800-A2 2.5 filter cover not seated flush
This topic has 7 replies, has 4 voices, and was last updated by
1 year ago August 3, 2021 at 6:09 pm My oil filter covers on the transmission do not sit flush with the transmission. One of the covers is leaking oil. (no leak at idle, then after shutdown the fluid seeps out). I also noticed in reservoir that there is a gasket at the base of the fitting over which the filter fits. Is this gasket something that was placed and should be removed? in the replacement filter assembly i only see the gasket that seals the cap and the o-ring that…

June 10, 2022 at 9:53 am Thanks in advance for any help given. I have a 2004 Sea Ray 500 with QSM 11’s. I’ve always maintained the fluids myself and had no issues. I was short on time so I had a marina fully service the boat in the fall of 2020. I took off, drove approximately 6 hours then put her up for the winter. In the spring of 2021, I checked all fluids. Both mains were on the low level mark of the dipstick. The port transmission showed a small dab on …
3 RepliesJune 11, 2022 at 6:57 am Thanks a bunch for the input. I too, was curious on the reverso and if oil was contained in the system. I will be talking to the yard in the next few days regarding topping off. I will be changing oil this week-end and again next week. Again, thanks for your response. DaveLast Post by:

ZF220A knocking noise
This topic has 3 replies, has 2 voices, and was last updated by
1 year ago March 9, 2022 at 2:36 pm Hello! After rebuilding a 6bta5.9 330 I noticed that the ZF220A gear is making a knocking noise when in forward or reverse at idle speed but it dissipates when the engine a little over idle speed (about 900/1000 rpm). No noise in neutral at any RPM. The noise seems to come from the forward side of the gear, almost from the bellhousing.

ZF286A Filter Screen Access
This topic has 2 replies, has 2 voices, and was last updated by
2 years ago March 6, 2022 at 2:07 pm I need to pull the filter screens on a pair of ZF286A marine gears. Does anyone know the size of the socket and Allen key for these plugs? The port engine is a hex nut and the starboard is an Allen key. Not sure why there’s a difference. Thanks.
2 RepliesMarch 7, 2022 at 7:40 am I read Robās article but didnāt want to assume the 220 and 286A were the same as I have to go and buy this socket. Also, curious as to the size of the Allen key vs. socket on the other gear. Appreciate the help.ĀLast Post by:

ZF286A Oil Leak
This topic has 1 reply, has 2 voices, and was last updated by
2 years ago March 6, 2022 at 2:02 pm I have an oil leak on the aft end of a ZF286A gear somewhere on the hydraulic pump. I think it’s coming from the lower left Allen key plug (see attached picture). I know the website mentions leaks from the hose mounting nut but that’s dry. Question is, can / should I pull each of these Allen plugs and use sealant to stop any leaks? I’d always followed the guidance not to seal straight thread fittings only tapered. If okay to us…
1 ReplyMarch 6, 2022 at 6:39 pm Nothing I see is is of much of a concern…………………..But, try this. Remove the allen cap screw ( that one or ??) , ONE at a time.. Use RectorSeal 5 on the threads andĀ entire cap screw and reinstall– UseĀ Common sense as to torque.. Two of the screws are longer as they hole the pump to the gear. The 2 shorter screws hold the pump together.Last Post by:

2 years ago July 10, 2021 at 9:22 am My 2010 QSB 5.9 gear oil cooler did not have sacrificial zincs.

January 26, 2022 at 11:06 am Hi. I’m in the process of restoring my ZF 220A gears and need some advice.Ā When I removed the gears, one case had traces of old white paint with a yellowish primer undercoating (perhaps etching zinc chromate) and the other gear was bare aluminum. I noticed some crystalized salt and white oxide dust under some of the paint on the painted gear which had pitted that particular gear in several areas. I have since removed …
2 RepliesJanuary 31, 2022 at 9:32 am Thank you Tony. Seems there are both ideas out there as I see most gears painted white, matching the engine. I would like to see the actual aluminum and address any issues sooner than later. Ill keep them bare, clean and protected.Last Post by:

2 years ago December 15, 2021 at 8:48 am I was 80 miles offshore fishing for swordfish yesterday. Mid-day we had a fish on and I tried to bump the port engine forward.
