1985 GL1200 LE Maintenance

Postby Rednaxs60 » Sun Dec 13, 2015 3:29 pm



Starting to do the maintenance on my GW. Thought I'd first take off the body panels and take a look for various items.

When I took off the top compartment, I had to disconnect the electronic travel computer, but it stays with the top compartment.

Found the regulator/rectifier tucked up under the forward left side of the top compartment. Nice spot, up and out of the way. Also located the three "yellow" wires in junction boxes just in front of the regulator/rectifier. In good shape and no signs of overheating. Will be leaving these alone. See Pic.



Looking for the rad cap and cannot locate it. Expect that there is more to remove on this model. Any help appreciated. The following pic shows what is under the top comartment.



Also looked where the side fairings were and cannot locate the rad cap that way.

Did get a good look at the underneath. The shifter seal appears to be weeping, but not leaking profusely. The head gaskets appear to be weeping as well. Intend to monitor oil levels and if not using, not touching at this time. Pics attached.







Overall I'm pleased with the condition of the bike. Always knew there would be maintenance.

Help locating the rad cap would be appreciated.

Cheers

Ernest

in your 2nd photo where your handlebars are, using a flashlight, look straight down between the right handlebar and the fairing. you might have to move a few wires and the rubber piece that's covering the top false tank shelter bolt out of the way to see and get to it. i had to do that with mine. its a b****h to remove the cap, but after a few choice words, and being careful not to bust open a knuckle or 2, you can get it off. the hard part is putting it back on again. its a "two finger" job, thumb and first finger to get it off and on again. make sure you press it down and turn it, (clockwise) to get the cap fully turned onto the radiator neck so it locks in place.

Thanks Roadwanderer2 - located rad cap as soon as I went and had another look. Moved the four connectors out of the way and found there is quite a bit of room. Now know that the lower fairings do not have to come off. Have the GW GL1200 Electrical Troubleshooting Manual and in process of trying to identify what each plug is. The White plug is C81 (YEL) - oil pressure sensor. Still trying to identify the C46 (GRN)/C47 (WHT)/C48 (BLU) connectors - not a requirement but want to know.

Pictures below show location of rad cap under the connectors.


The following 2 pictures show rad cap exposed.

Timing belts - Gates T070 (qty 2) - were delivered today from Amazon.ca. Ordered 10 Dec - shipped on 11 Dec, pretty good service.

Stuart - only so much room and lots of things to stuff in. Have a lot of wiring to address, bit at a time. Looking at the timing belt covers and looks like the rad has to come out at the same time so I'll do the flush at the same time, maybe take the rad in for a cleaning. The upper rad hose is in good shape. Noticed that the rad has writing on the side of it much like you'd expect to see from an auto wrecker. Makes me think that it has been replaced some time back. Lots to do between now and February. Always nice to know what is there.

I found that if you go to Harbor freight they have a nice set of large needle nose pliers one is a right angle and the other is strait. I use the strait pair to help put the rad cap back on and tighten down ( I have large hands) get a set of these as you will need them for other jobs on your goldwing.--------------------------Hal

that's true Ernest, one step at a time and yes, it will be much easier to get to the timing belts with the radiator out of the way and you can also get to the water pump to inspect it if need be.......Hal, i have a pair of those long needle nose pliers too. they do come in handy.

Right now I'm into cleaning up the electrical as I'm still waiting for parts. Lots of splices and wires going nowhere. Identifying and trying to clean up the wiring in behind the CB unit. Will do a schematic of what is there and post it. Lived on a 40 foot boat for 5 years and wiring was always an issue. Love a challenge.

Put the bike back together, and only the CB doesn't turn on. I think this is a connector. There is a connector coming from the forward end of the compartment that I do not know what it is there for (see pic). If anyone knows what it is for be glad to know.

You can see the connector in this photo that I am interested in.


Here is a picture of the back of the CB unit. The top and middle components are not connected to anything. The lower connector with the black and grey leads is connected to the radio interface and other areas (haven't identified all connections). Anyone else have a similar setup?


In this picture you can see the four components stuffed into this compartment. The Panasonic amp, the CB unit, antenna coupler and multifunction box.


The front wheel bearings have arrived, as has the bleed kit from KapscoMoto in Mississauga, ON. Waiting for the front rotors and still have to source belt tensioner pulleys.

Cheers

turn the squelch knob all the way down to minimum and the volume down on your CB, it should come on via your radio speakers, there should be a button you can press on your radio for "cb" on and "cb" off. follow your antenna cable from the back up thru the frame and see if the antenna cable plugs into that one that your looking at in your photo. i have the same cables on mine. if im correct, that is your antenna connector,

also, take a look at this thread, you can find the tensioner pulleys and how to replace them onto the mounting plate here......... viewtopic.php?f=11&t=10919&p=159510&hilit=timing+belt+pulleys#p159510 use the same part numbers that shows in the photo. you can get them at either Napa, or o'rielleys auto parts. if you get them from o'rielly's, they cost roughly $22.00 US each, and the rest of the hardware you'll need you can also get from them.

cut the old pulleys off the mounting plate with a die,(angle) grinder, take the plate with you to the parts store to make sure you get the proper fit bolt nut flat washer and lock washer. the bolt should "just fit" thru the mounting plate and the flat washer should fit perfectly inside the recessed part of the bearing and the lock washer should snugly inside the bearing. when you put the bearings onto the mounting plate, go ahead and tighten them down nice and tight. the bearing should still turn without any resistance. if it doesn't, back off the nut just a hair. this is the exact same thread i followed when i replaced the rollers on my 83 1100 and they came out perfect.

keep us informed on how its going.

The plug looks just like my helmet plugs, where helmet audio is plugged in.

not trying to hijack this thread.....but is that black cable with the blue tag around it, is that YOUR antenna cable? what is the one with the black rubber cap on it for? i don't have those on mine. it seems that someone along the way replaced, and or removed some connectors under this bike's false tank shelter. i don't have any information to go by.

im sorry, but had to ask.

Stuart - good question. Will go back in and provide further information. The cable in question is the one that has no marking on it (the black one). I have perused the manuals I have and have yet to find additional information. Cheers.

Mentioned that I'd keep digging and identify the 4 couplers above the rad cap. I have found what each coupler is. First the photo.



The blue coupler is the Tw sensor (coolant temperature).
The yellow coupler is the oil pressure sensor.
Green couplers is the PBR (pressure) sensor
White coupler is the PBL (pressure) sensor

Got the information from the manuals that I have. They are: Haynes - Honda GW 1200 '84 thru '87; Honda GW GL1200 Electrical Troubleshooting Manual; Supplement to the GW GL1200 Electrical Troubleshooting Manual. Lots of good information, but takes time to digest.

I know a LE has many more wires than my 1200 Aspy ...
but...
as long as you are cleaning up wires and such ...
and just considering all the odds for ANY GL1200... even if they look " Clean/unburnt "...

I would highly recommend :
A ) Unplug the three yellows near the battery
B.) Do the three part test on the stator, and the 3 part test on the reg/rect .
C ) Cut/clean, and lineman splice with hard solder , and triple shrink wrap the three yellows at the battery, and all the yellows, red's and green at the Reg/rect ( Or buy a GL1200 harness from electrical connections ... same soldering involved )

Better tested and all that , rather than sorry when stator or reg/rect blows up 500 miles from home.

SilverDave - thanks for the suggestion. Will revisit the wiring again. Did not see yellow wires close to the battery - check again. Seems this is a common thought regarding the wiring on the 1200.

Checked out the harness at Electrical Connections - Hon GL12 Stator Coil Harness. Will contact company and discuss. Appears the wiring size has been increased (always a good thing in electrics), and the coils are hooked up differently.

Thanks for the input. Cheers

Rotors came in today. Also did more research on the stator/regulator wiring. Found a good picture of the relay to hook the coils up to the battery. It appears to be a Rayex Electrical LD1A-12F. Will be looking for a source in town. Cheers.

I did a search on it and found this: http://www.jameco.com/webapp/wcs/stores ... _171460_-1

That's just a standard 40 amp SPST automotive relay. Any quality 40 amp automotive relay will work for this application.
