    Kawasaki FR691V cam lobes with ball bearing

    slomo: I'm not quite sure what you are saying in your post, but I did ensure that the crank and cam punch marks aligned. If is curious to me that, despite multiple posts regarding the hole punched in the valve push rod pocket, and many kind attempts to help with my problem engine, no one has...

    Kawasaki FR691V cam lobes with ball bearing

    cpuvis: There is no oil in the muffler, except what is coming from the cylinder. slomo: Yes, this is the 180 psi compression engine, a Kawasaki FR691V. The ACR does not adjust the timing rather, it temporarily opens one of the valves on each cylinder to reduce the compression...not sure whether...

    Kawasaki FR691V cam lobes with ball bearing

    I previously asked about the possibility of the valve push rod pocket with a hole in the bottom (next to the tappet),that had the bottom knocked out by the loose push rod, allowing enough oil to get into the valve cover to enable it to leak through the valve shaft seals and into the cylinder...

    Kawasaki FR691V cam lobes with ball bearing

    When I removed the crank case cover, the cam + governor assembply just lifted out of the case. The fingered governor plate stayed attached to the governor control lever, which is part of the cover. I completed reassembly of the motor today, fired it up, and the behavior has not changed...still...

    Kawasaki FR691V cam lobes with ball bearing

    I see that the cup and six ball bearings, that I previously asked about, are the governor mechanism. I note that neither the crank case cover and/or cam installation proceedures mention any special process to engage the two "fingers" on the governor shaft into the cam shaft. Is it correct...

    Kawasaki FR691V cam lobes with ball bearing

    Anybody know what the cam lobes measure out of the box? The service manual, as usual, only gives the minimum value.

    Kawasaki FR691V cam lobes with ball bearing

    The Crank Case Cover has no Gasket and relies on a soft sealant. What sealant is recommended?

    Kawasaki FR691V cam lobes with ball bearing

    I measured the Cam Lobes, and they measured: 1.150", 1.150", 1.154", 1.150". The Service Manual shows a limit of 1.156". This is slightly below the service limit, is this close enough?

    Kawasaki FR691V cam lobes with ball bearing

    I wish I was comforted by the high compression but I know from experience nothing comes for free. The service manual clearly states a compression ratio of 8.2:1...and that doesn't add up to 180 psi. I checked the crankcase breather (valve?) and it is completely open both sucking and blowing on...

    Kawasaki FR691V cam lobes with ball bearing

    Lawn Addict: Righto, I had a brain-fart regarding the flywheel key. Upon disassembly I had already noticed that the flywheel key was in the key-way. Also, you correctly quote the line from the service manual regarding compression, however it specifies the minimum compression. My previous...

    Kawasaki FR691V cam lobes with ball bearing

    Slomo: Thanks for you last post. At least we can have some fun. Per your last post, I've been through the rings, and they appear fine. I might just let the 10 acres of grass grow...how bad could that be? I do sincerely appreciate your effort.

    Kawasaki FR691V cam lobes with ball bearing

    I have not checked the flywheel key for proper alignment, nor do I know how to do that. I'm not sure how a flywheel key could have become unaligned. Tonight I checked the HF compression gauge by pressurizing it with my compressor, and it agreed to the psi with the gauge on the compressor. YES...

    Kawasaki FR691V cam lobes with ball bearing

    Slomo: I know the valve push rod doesn't push directly on the valve, however it is the push rod associated with the valve. I assume you're messing with me. Head gaskets = brand new Heads torqued to spec (oh god, its a HF torque wrench) Checking the breather hose/port tonight, will advise...

    Kawasaki FR691V cam lobes with ball bearing

    Slomo: The only timing check that I am aware of on this engine is ensuring the alignment of the punch mark on the cam gear and the crankshaft gear. I did check that and they are aligned. All gear teeth look like new. I don't see how the ACR would affect the compression test anyway, since I...

    Kawasaki FR691V cam lobes with ball bearing

    Engine was not filthy, just a little dirty. The fins all looked brand new and have never been clogged. It has been established that the valve guide softened and relocated, so at some lever it overheated. I think we are done with the valve issues. Per the previous posts: after replacement of...

    Kawasaki FR691V cam lobes with ball bearing

    Regarding the 180 psi compression: Is it possible that I am measuring the compression improperly? I'm removing one spark plug and screwing in my trusty Harbor Freight gauge. I've been measuring it with the carb removed. (not removed for the test, it just happened to be off). The service...

    Kawasaki FR691V cam lobes with ball bearing

    To clarify: the valve guide on the valve that bent the valve push rod sits 0.040 in. above the height of the other valve guide in the same head, measured with the valve oil seals removed. Anytime I said "rod", I meant "valve push rod". Anytime I said "guide" I meant "valve guide". When I said...

    Kawasaki FR691V cam lobes with ball bearing

    Slomo: Sorry for any confusion regarding terminology. I was referring to the valve guides as the component that moved out of position due to excessive heat...which I recently acknowledged did, in fact, happen. I lapped and dye-chemed the new valves when I installed them, and the valve seats...

    Kawasaki FR691V cam lobes with ball bearing

    I stand corrected regarding the valve guide migration due to over heating. The better description given here of the problem got me thinking: After making the distinction between the valve guide and the valve oil seal, I retrieved the failed head and accurately measured it with a plunge...

    Kawasaki FR691V cam lobes with ball bearing

    Some good points raised. I had already come across the issue with the valve guide/seal being pushed out of position, and the relationship to running the motor hot with dirty fins and related. I carefully had previously inspected the valve seals with that in mind, and saw no indication of that...

    Kawasaki FR691V cam lobes with ball bearing

    Thanks all for the information. Yes the battery does have a tough time turning it over. For reference: When I said I was inexperienced; I should have said that I have no experience in small engine repair. I do not work in the industry. I will focus on the ACR mechanism. Does the smoke and...

    Kawasaki FR691V cam lobes with ball bearing

    Ahhh, I understand. The cam you have pictured appears to be what I am dealing with, and I have noticed the additional six ball bearings that you mentioned. Thank you for that input. One thing I noticed is that the intake and exhaust valves cycle normally on one cycle, and then return to the...

    Kawasaki FR691V cam lobes with ball bearing

    Greetings to all, new member here. I am working on a Kawasaki FR691V 23 hp 2 cylinder engine, and after dismantling it and removing the cam shaft, have found that the two lobes nearest the PTO each have a single ball-bearing on the bearing surface of the lobe. I repaired a bent pushrod...
