'99 1500 Maintenance

Post by lgjhn » Thu Apr 11, 2019 8:22 am



First post here and I want to give a BIG shout-out and thank-you to this site, and the folks on it, for all the great info that's available here.
FWIW, I'm a small one-man shop in SW Louisiana that primarily caters to the general maintenance of the GL1800s.
About 3 weeks ago, a guy brought me a '99 1500 with only 34K miles on the clock, asked me to go completely thru it and fix/replace anything that was wrong.
Before starting, I asked how much he wanted to spend because this could get really expensive really quick and would likely make a good down payment on a new bike.
I also told him I was NOT a carburator guy and had no intention of even attempting to touch it.
He trailered it here, got it off the trailer, it started right up with 20-year old belts...and rode it into my shop.
He loves that 1500, money was not an issue and has no intention of getting rid of it.....ok, so up on the table lift she goes.
Well, I come to find out that he had ridden the bike to Alaska twice (2013 & 2014) from SW Louisiana on the same set of tires! Then, parked it if that tells ya anything....LOL
Fortunately, the bike was stored out of the weather in a somewhat air-conditioned environment, and he ran it enough to keep the fuel fairly fresh.
Just about everything on this poor bike was in need of attention/repair...I mean everything. I started at the front wheel and worked my way to the rear wheel.
Both tires replaced (over 5 years old and worn to the cords), front wheel bearings were shot and were replaced (rears were ok), shock maintenance, oil/filter change, rear gear oil change, three brake calipers completely rebuilt with new pads (2 of 6 pistons badly corroded beyond repair and had to be replaced, all 4 pad pins seized and had to be replaced), both clutch & front brake master cylinders completely rebuilt (both leaking like sieves), clutch slave cylinder leaking and completely rebuilt, rear brakes seem to be working ok (good thing as I can't even see the rear master, let alone get to it to work on it), petcock rebuilt (slightly leaking), all 3 air filters changed (sub filters crumbled in my hands, probably originals), got the pneumatics back working on the shocks (someone along the way left the plug undone under the right side shelter), and just an overall good cleaning. All the hoses appear to be ok...at least so far.
What I have left to do is replace the 20-year old original timing belts. New plugs and a coolant change will happen with the belts change. Hopefully, I'll get most of that work done today.
Also, I need to take a stab at changing the shifter shaft seal (slightly seeping).
IF it weren't for this site, I'd have never taken on this job. This site has been a Godsend.
Another positive is that this job helped me become more familiar with the 1500s....lol...boy, did it! :)

See thread linked below....

If you are going in as far as to change the shifter shaft seal, you might ask the owner if he's interested in installing a shifter brace, the shifter seal is notorious for leaking on the 1500, and the brace helps preserve the seal, and greatly improves shifting, too.

The brace is sold by Cyclemax and is about $130

Wheel bearings at only 34K??\
That's weird.
My 1500 has 90k on the original bearings.

"...Wheel bearings at only 34K??..."
Yep. That's what I thought too when I got the front wheel off and checked em. I was like...WTH?? I had a 167,000 mile GL1800 in here last summer for a tire change that still had the original wheel bearings according to the owner who's owned it since new, and they were still good. I did notice that someone had slathered a pile of never-seize, instead of grease, on that front axle (pretty messy) at the last tire change. I could see where some of it had migrated to the bearings. Not sure if that had anything to do with it or just the roads he's been on. When I talked to the owner about it, he told me that on both trips to Alaska, he went across some of the most terrible roads he's ever seen; really bad and rough roads...some of em were nothing but packed, pot holed gravel for many, many miles. I showed the bearings to him and without hesitation he told me to get em outta there. Left side bearing was totally shot. The right side was so-so. Got the All-balls from CycleMax. BTW, CycleMax has been absolutely great at helping in getting parts etc. for this beast.
FWIW, I got the timing belts changed today...the job was not nearly as bad as I expected. Even though the old belts looked good, I knew better...lol. They felt pretty "brittle" compared to the new Gates ones. I'm pretty sure that they were originals too. I could see the Honda part# on one of em. I think he's petty darn fortunate that one em didn't break on him. The tensioners both checked out ok so I reused em. It's all back together with new plugs and fresh coolant.
I've got to get a hold of him tomorrow and ask him if he's interested in the shifter brace since I'll be in there pretty soon.

Just out of curiosity, about how many hours so far on the service?
You never said but how does it run.

Just some background, I'm "old & slow" at 68.....LOL. I'm retired out of the oil/gas industry a few years ago. I assembled a fairly well-stocked shop (40'X80'), but I don't do bike maintenance as a full-time thing, nor do I any advertising at all. I've been working mostly on GL1800s for about 3 years now. I've established a good-sized customer base in those years. It's a sideline for me but for the first time in 3 years, I've actually had to turn away work. Lately, I've been swamped.
Back to your question: I've been poking away at it in between pre-season servicing of a couple of GL1800s (oil/filter changes tires, etc.) plus the other things in my life...2 funerals, dentist/doctor appointments, a wedding, getting taxes done, a couple of trips to Baton Rouge, etc.
If I had to add up the equivalent hours, I'd guess probably a couple of weeks worth...maybe a tad more. FWIW, I don't normally work on the older bikes so I was, and am, taking my time not to break anything on this 20-year old bike, especially in getting the Tupperware off and, of course, to do things right. Some things like oil/filter change, gear oil change, tire changes, clutch slave rebuild, master cylinder rebuilds, caliper rebuilds are practically identical to work I've done on the 1800s many times so that work went fairly quick. Petcock rebuild and timing belts? Well, those aren't things I do everyday so it went slower, but neither one was really all that difficult once I got to where I could actually work on em. Getting to em was harder than the actual work...LOL
The owner is not in a rush to get it back and we agreed on a "pay as I progressed based on what I found", with an upfront payment for parts, materials, etc. He's been good about it and been paying me.
I just got the new plugs & fresh coolant back in it yesterday evening after the belt change. The belt change took me most of the day yesterday as I wanted to make absolutely sure everything was correct, especially on the timing. I noticed nothing leaking earlier this morning so that's a good sign...LOL. I haven't run it yet, but I need to so I can top off the coolant, check for leaks, etc. which, in turn, will allow the tupperware to go back together. I have a GL1800 coming in here for a tire change, both front in back, later this morning, and another one coming this afternoon for a "brain change" so I'm probably gonna hold off firing it up for a little bit until I get those turned around and on outta here. Once I fire it up and everything checks out ok, I plan to test ride it a few miles to ensure everything is ok before releasing it back to him.

Thank you for the welcome. This is a great site for sure. It is a treasure chest of good folks and valuable information.
I finally got a hold of the owner and he didn't want to put the shifter brace on. I practically begged him to do it, but he wants to wait.
So this morning, I went on ahead and changed out the shifter seal. Once I had that outside shield cover off, it took me about 45 min. or so to do it.
In WingAdmin's 2013 writeup on this issue, he mentions the particularly poor design, probably done by a committee. There's truth to that!!
Whadda a poor design it is. That little bearing in there is way too small for the loads it sees.
Probably the worst part of the job was getting that inner pivot bolt out and back in. The "shop towel trick in the socket" once again came to my rescue for getting it back in there. A swivel socket adapter and long extension made short work of that. Then, like many others, I found that there wasn't enough space to get the arm off the shaft as it was just ever so slightly binding against the frame. I was already planning on loosening some mounting bolts, but I musta been holding my mouth just right because after about 5 minutes of fiddling with it, it literally fell off! About 30-40 seconds on a 60 grit bench disc sander made sure that was never gonna be an issue again. :). The old seal had migrated out quite a bit and practically fell out when I pulled on it with a pick. A small amount of oil started dripping but soon stopped. I cleaned everything up and went back with the new seal. It went in easy...almost too easy for my liking. IF I should ever have to do it again, I'll probably run a light coat of HondaBond HT on the outer surface before seating it on there. Monkey finger pliers made short work of seating it as my fingers were too short to push it all the way.
The old seal looks like it was leaking more around the outside edges due to the migration rather than to any wallowing on the inner shaft protrusion area. All in all, not to bad of a job. It looked way worse than it really was. I no more than finished it up and the power went off due to heavy storms and tornados passing thru our area. We just got the power back a little bit ago. Hopefully, Monday the weather will be better, and I'll try to get a test run on it.

he should have let you install the shifter brace pivot.... that IMO is the weakest point on the 1500s.

had a 94 and 98, both of them had sloppy shifting do that OEM inner bearing not being strong enough.

with what you have done, IF, he will ride it every 2 months year 'round, it will last him as long as he can sit on it.

I fully agree. Like I said, I begged him to let me do it.
Anyway, this morning was the big day since the timing belt change....had it on the trickle charger overnight to ensure a fresh battery. I fired it up this morning. it started right up on the 2nd try. Let it warm up to operating temp and go thru 2 fan cycles. While it was warming up, I topped off the coolant and checked for leaks. No leaks. :) The Tupperware is still off and there was plenty of general engine noise, but I noticed that once it warmed up, most of it disappeared or was greatly diminished.
I still noticed the raw gas smell after shutdown and I need to trace it and see where it's coming from. I just rebuilt the petcock so I know it's not that. Could be the vent off the gas cap. Anyway, I'll find it.
Other than that, she idles perfect, once warmed up, there's good throttle response, at least in neutral, etc. but I didn't ride it. About the time I shut it off, a riding buddy stopped by and asked if I'd like to head on down to Avery Island to the Tabasco factory....about a 200 mile round trip for us. It was beautiful day here in the high 70s, I just couldn't resist...LOL. I grabbed my gear, jumped on my '15 F6B and we spent the rest of the day out on the road.

That will be a GREAT bike when you finish it.
I have a '99 myself, and I just love mine.
Mine has 90,000 miles on it, still like brand new.
