Wanted XJ550 Inner Cam bearing caps.

In this thread. Please be kind. I have made yet ANOTHER colossal and stupid mistake while trying to take the engine cover off. I was thinking righty loosey lefty tighty and ultimately broke these clamp type things (See photo). What do I do. How do I get new ones! Please help.

 

Someone on here can probably find them, or has them.
I would message xjforever, the engine icon top right, Len a.k.a. Chacal may have them or can probably point you in the right direction.

 

Mind if I move this into the wanted ads?

 

I think I have a couple of them in a box somewhere

 

The good news is you broke the ones that are not cam caps, so all you need is two new replacement ones. We all make mistakes, no shame in that.

 

please do

 

Seriously. How much?

 

Oh no, I broke all four of them. I'm just showing you one side. All four of them are toast.

 

When you get new ones the torque specifications assuming you have enough clearance to get the torque wrench in below the frame are 10Nm for the cam cover bolts and 10Nm for the camshaft cap nuts so l believe the sheared bosses for fixing the cam cover next to the cam tunnel are the same.

 

Two of them are actual cam caps. For the most part they an interchange, but you should get some plastiguage to make sure the clearances are still within specification. The cams run in plain bearings that are line-bored with the caps in place on the bare head. The only issue will be if the replacements are worn beyond being useable. You will also want to measure the cam endplay, since the inner cam caps also keep the cams from moving to far to the left or right.

If someone on here does not have a set to sell you can get tnem on Ebay, but might need to buy a used head to do so.

 

ebay heads no cams choose one that still has the valve buckets and shims for best deal gonna cost about 60$ to 80$

Standard or yics head? I think the only ones I have are for 650/700/750 engines. Don’t know if they are interchangeable. Caps in pic look like yics caps but head looks like standard head ? Maybe caps have been replaced before. And they look like they are the wrong way around.

 

Awesome! Thank you for sharing. My uncle said he could fix mine. He's a welder but I'm thinking it would be best to just replace them entirely.

 

No disrespect to your uncle but better to replace them with second hand parts I think.

 

If the FZ600 fits, I assume they will, you can have them, postage is all it will cost.
You do the research. If they’ll work I’ll dig them out.

 

he is some new ones from ebay says 550 450 and 750 have same caps

I appreciate every one's response but I think I just pretty much killed my engine. I proceeded to do the valve job (6 of which were out of spec) I used the zip tie method to hold down the lifter so as to fish out the shim. Yup, you guessed it. The end of the zip tie snapped and is now lodged inside. The crankshaft can only turn so far and then it gets completely stuck. If I owned a gun....
I humbly ask all of you what are my options at this point.

 

Try using air through spark plug hole and see if it will shoot out through the intake or exhaust.

 

Yes Toomanybikes worth a try. If he has a borescope he can possibly see it if it is on the piston crown. A piece of rubber hose attached to a vaccum cleaner could be used to get it out if it is on top of the piston. If he had a cork that would go into a vaccum cleaner hose with a hole in the cork to take a small rubber pipe which could go through the spark plug hole. Might work, just brainstorming.

 

Bingo @Franz
Or if intake and exhaust is off stick the vacuum right on the motor.

 

I lost one of the caps that straddle the cams just to the right of the sprockets on my YICS xj650 maxim they are not
bearing caps but only holdowns for the YICS valve cover. If you have one to spare I would buy it.

 

We do have these non-bearing caps as reproduction items:

HCP22924 Aftermarket camshaft journal NON-BEARING CAM CAP. On many engines, on the right side of the cam tunnel opening there is a non-bearing camshaft cap. Unlike all of the other cam caps, which actually hold the camshaft down to the head and actually have smooth bearing surfaces…… the only purpose for this cap is to supply a threaded hole to accept the valvecover hold-down bolt. This same cap is used on both the intake and exhaust cams, and is on the right side of the cam tunnel opening. NOTE: on the left side of the cam tunnel opening, there is a very similar-looking cap (also with a valvecover bolt acceptance hole), but that cap is an actual bearing cap. This replacement non-bearing cap, although similar, cannot be used in place of that actual bearing cap. This non-bearing cap is easily cracked and broken if its valvecover bolt is over-tightened. And unlike the original cast aluminum cap, this cap is machined from a billet of high-strength T6061 aluminum and features a much stronger profile than the original cap. Fits all of the following engines on both the intake and exhaust camshafts: XJ550, 1984-85 FJ600, 1986-88 FZ600, 1986-90 YX600 Radian, 1984-91 XJ600 Euro, all 1982-83 XJ650 Maxim (YICS) engines, all XJ700 air-cooled, all XJ750 air-cooled, and all XJ900RK, RL, N/FN, and F engines. NOTE: XJ900 engines actually use 4 of these non-bearing caps, located on both sides of the cam chain tunnel. Each:

 

Hi Joe
Going to have a look this morning and let you know. Intake or exhaust or does it matter?

 

On the non-bearing caps, it does not matter, they are both the same.

 

Found one. $30 including shipping and handling
Need address and PayPal email

 

I swapped an xj750 seca master cylinder with Hogfiddles for a pair of those

 

I have 550 head spare parts.
