water pump

I just bought a 1982 GL500 to restore. It's 98% original/complete. Only 5k miles Before I want to even think about starting it I am doing fluid changes, spark plugs, filters, etc... Today I changed the oil and found this white goo resting at the bottom facing side of the filter cap. From...

Hi forum! I'm made it back after a year and 42,000 km on my CX500 around North and Central america. Had to rebuild the engine a couple times, so I'm getting better at taking care of my CX. In the last rebuilt I used half of another engine to fix the problems i had, but the camshaft's rear...

I am leaking fluid around my water pump cover and was told that I need to replace my mechanical seal. I got on eBay to buy this mechanical seal but didn't realize till after I bought it that I bought it for an '83 and I have an '80. Does anyone know if Honda changed the mechanical seal at all...

Hey guys, I'm a newbie to mechanics, but last winter took apart the master cylinder, breaks and carbs. I rode my '80 CX500c for 2 days and then it died. I pump it in a local shop and they are saying the stator went on the bike. It wont turn over at all. They quoted me $1300 ($400) of which is...

Howdy. Try as I might, I can't find access to the Shep Method of mechanical seal installation. All of the links seem to lead to an external site that is no longer hosting those files. Can anyone point me in the right direction? Also, I've seen on our CX500 Forum that Yamaha makes a mechanical...

Hi all, I'm reassembling the water pump, currently trying to build a tool to fit the 28mm mechanical pump seal in the hole meant for a 27.5mm but I also can't find the crush washer that is meant to go on just before the dome nut. Does anyone know where to get one or what to look for at the DIY...

Hey again forum. Nearly done with a rebuild on a 1980 cx500 custom (picture and video for kicks below!); but just trying to sort out one last mechanical issue. Bike overheats after 5-10 miles of constant riding (assuming wind/temperature are doing basic cooling during the starts). Have...

Here's a little background info before we get into it, recently bought an original 1978 Honda cx500 from a family member. It sat for a about 4 years after he replaced the alternator, statter and did a carb rebuild. Going into it I knew it had an oil leak (bad seal on the back casing) and it...

Newbie here with an overheating question. Bike is a 1980 CX500D (working on figuring out how to add that to my signature) I just finished cleaning the carbs using Larry's book, and now the bike is overheating (or at least saying it's overheating) extremely quickly. Like into the red in ~5 min at...

Hi again everyone! It's been a while, but I've been busy with life and working up the civil-service ladder, and winter... Anyway it's warmer here now and I just took my GL500 out of storage and got it running. Aside from a stone-dead battery that refused to fully charge and was replaced it...

In the process of doing a triple bypass on my '80 CX500C, I found that the water pump mechanical seal hole was a few thousandths of an inch too small for the currently available seal, so (per forum advice) I took the rear casing in to a machine shop and showed them exactly what I needed- the...

ISSUE: Seal sent was too big. EMAIL SENT:: I recently purchased a few items from you guys for my 1981 Honda CX500 Deluxe, but specifically the Mechanical Seal (1921711000) isn't the same size as my original seal. It is bigger by 30,000th of an inch (.03). REPLY:: Hello Paul. Thank you for...
