Looking for circulating pump for G56

[zzman]

I've been searching for a pump in the price range under $75

It needs to operate up to 300 degrees, about 1 gal per minute, 12v and the pressure can be minimal.



I found some from 90 to 300 bucks but that is just to steep for my experimental project.

Anyone have any other sources or ideas, just a pump maybe, I could maybe get a motor for it.



Thanks

I'll be watching for your experiment, its funny, I just started a search for a pump, for running my G56 oil through a heat exchanger. But I'm concentrating on getting my clutch and DMF replaced at the moment. I thought about a low pressure oil filter setup then flowing through a heat exchanger, but I don't want it to be critical if it failed.

Here is a link with the prices and engineering data, and its way under your budget.

My guess is he wants a pump rated for continuous use.

 

[GCroyle]

Never seen the innards, but the 99- Ford 7. 3L manual trans ran cooler lines to the radiator, visible on the RH side.

 

[zzman]

Yes I found this G56 runs hotter than the NV5600 I had in the 04. 5
Bearings are singing pretty good now, before I rebuild this one, I want a cooling system installed.
The tran-cool from Geno's I don't think will help enough, they worked OK on the NV.
The pump I need will probably need to operate with the high temp of the oil, my guess would be up to 300 degree max.
RVTRKN seems to have the same idea, I've already changed clutch and flywheel. I found a finned cooling system and I would operate the pump manually with a switch while monitoring a temp gauge.
I feel this IS a must for my conditions.

This is the pumps I found but with a steep price.
There should be some small slow flowing low pressure HOT fluid pump somewhere that could be used.
I'll check the local flea market on the first Monday in Canton Tx. I find all kinds of stuff there.

What oil are you running in the G56?

 

[RustyJC]

You might check Remco to see what pump they use in their kits to circulate ATF in vehicles being towed. I'm not sure how expensive this pump would be if you could buy it from the original supplier (I'm sure Remco wants an arm and leg for it) or what the temperature limit might be, but these pumps run continuously while the automatic transmission vehicle is under tow.



I believe their website is http://www.remcotowing.com.

This (problems with the G56), is why I went with the 68RFE. knew about the DM Flywheel but not the hotter temps. . Wonder if a Eaton 6 speed Manual can fit. .

 

[zzman]

I use 1-1/2 qts over-fill with Pennzoil Synchromesh

Allways have and will I guess.

 

[RVTRKN]

I checked into the Eaton trans but adapter cost more than its worth. zzman, have you tried using a girdle on the trans your heat might be the gears meshing wrong. I don't monitor mine at the moment, but that's a major reason for failure and will have a girdle and temperature sensor in May.

 

[zzman]

Na I don't know anything about that. I've herd folks talk about that. So I guess the G56 case probably warps and twist with heat or something.
My plan is to have Standard Transmission in Ft Worth to rebuild but if too expensive or a total loss then see if I can convert to a NV5600.
I need to keep this truck for atleast 4 more years, about 75k mi a year.
I just had the head gasket replaced, so I'm not feeling too good about the 6. 7 w/G56 combo.

This trans does whine in all gears except direct (5th) and it gets real hot in 6th, so I'm not too pleased with this truck. The 04. 5 seem to be much more of a tougher truck.

Well the girdle thing seems to be a crutch and I wouldn't feel too confident with it.
Heck I may be better off trying to find a 12 valve and just start over.

 

[RVTRKN]

Well I have only 44K miles on my C&C, so with the clutch or DMF failure, (won't know until trans is removed) I'm having Richard in the Tucson branch of Standard Transmission go through the G56 as exploratory and cleaning before I change the oil to "Mobiltrans SHC DC". So if I know the trans is in good shape with the SMF and SBC DD 3250 Clutch, along with the Mercedes approved oil for the G56, it makes since for me as far as the dollar cost goes. The Girdle will be installed when the trany goes back in, so if you look at the cost divided over the life time of the Truck, it works out to be cheaper. I did research the possibility of installing a Eaton 6spd trans, and I believe its possible, but the cost of adapting to the CTD and miscellaneous items was around $10K. I believe the trans will be strong enough for my 23K GCVW, and probably more if needed. TDR wrote a good article on the problems of the G56 and seem to be confident with a SMF and Girdle it can withstand Hotshot duty, or at least have a good chance of it anyway. On another note the G56 is capable of Dodges GCVWR, if the DMF holds up.



EricBu12, in 06 there was little known about the ability of the G56 behind a 5. 9, 6. 7, CTD, and I hate auto's, so I had a hard decision to make. With the 48RE as an example to compare the unknown 68rfe with and the unproven Aison in late 06, before I ordered my C&C in Jan 07, I took my chances on the proven G56 in the medium duty trucks Mercedes Built. I wished I had the luxury of 2 more years to make a decision, I probably would have chosen the Aison, but would have always wondered, what if, if I would have stuck with the G56. If someone delete's a 6. 7 with the 68rfe and up's the HP/TQ they will have to upgrade the trans and spend more dollars than what I'm spending to increase the ability of the G56.

 

[EricBu12]

RVTRKN,

Yeah I get what you"re saying. . I heard in 09 that the DM Flywheel was not good. . wears out and slips very soon. . and with my other problems with the NV5600 on my old 01, and that components parts availability, I went with the 68RFE. I got it off the lot and there was a discount as it had 500 miles on it when I bought it. Other than the DPF, it has been trouble free. . well I have a couple leaks underneath but they will be fixed soon. .

 

[RVTRKN]

Thats the price we pay for the increased HP/TQ, from the Horse Power wars. The G56 was in a lower HP/TQ application and then ran at lower Gear ratios for both the rear end and the trans itself. Thats the only explanation as to why they thought it would replaced the NV5600, plus they make the profit instead of installing Eaton transmissions. Now that would be a good looking badge of honor next to the CTD.

 

[kkelley]

I swear that it's the damn manufacturers driving the death of the manual transmission.
'Nobody's buying manuals anymore' they say... . Well sell a vehicle with options and a manual trans available. Make sure the manual is of decent build and they'll have no issues selling them.
I don't care for autos, never have, and never will. But reading of the G56 not holding up all that well worries me. I'm not going to go and spend a couple thousand dollars to possibly make my trans hold together longer. I'll wait and upgrade as things fail. If/when the flywheel kicks the bucket, I'll probably just get another one like it. I had changed the DMF for a slightly lighter standard flywheel in my old GTI, and it did nothing but jack up the idle, and introduce vibration to the gears. It had a horrible rattle when in neutral, unless I stepped on the clutch. I can only imagine that with a transmission with this much mass, and an engine that already vibrates, I could end up with some bad wear or even breaking parts.

 

[EricBu12]

Rvtrkn I agree a nice 6 or 9 speed Eaton transmission would be sweet. I heard of the DMF not being good and went with the 68 RFE. So far knock on wood and 40k miles later with several mountain trips, the transmission is holding up well and i pull a 36' 15k 5th. . I am a FedEx truck driver and our new Volvo tractors are getting 12 speed autos in them.

If buyers will pony up the freight for the Aisin auto, they may also be willing to pay for a true MD truck transmission.

I don't think the problem is willingness to pay for it. I believe it is the drivability. The engineers are not going to put a transmission in that requires double clutching, nor one with a trans-brake. They keep making things more 'car like', which means easy shifts and no noise. I don't think a transmission exists that shifts like a car, but can handle some amazing torque, while towing.
I like the old days of the rattling engine and shaking shifter!
