Spanner?
« on: October 18, 2018, 05:03:37 PM »

Hello.
I have a 2011 FLHTCU cvo
I am in the UK so maybe what you recommend is not available here but I will try anyway. I intend to remove the rocker cover and rocker box with the engine in the frame. This so I can change the lifters. Last time I had these off it to an age to undo the setpins holding the covers on because I could only turn the ones tight on the frame by 1/4 turn at a time. Would a ratchet ring spanner help, if so does it have to be cranked and/or very slim and what size does it need to be.
Any help appreciated.

Borrow a pair of bolt cutters and cut the stock PushRods in half to remove them, buy quickie PushRods and lifters and tappet gaskets.

Remove tappet block change lifter put gasket in, replace lifter block, and install / adjust PushRods i

John,

I just did the job on my 2010. imo it´s necessary to change the cam bearings and the Tensioner pads directly too. Use the Jim´s tool for the bearings. If you need any help in job or tools/parts over here in Europe let me know

Thanks' all for taking the trouble to reply.
I am not using the adjustable pushrods, I presume, could be wrong I know, that they are heavier than the standard pushrods, which to my way of thinking puts extra load into what appears to be an already fragile valve train system.
Regarding the upgrade to the valve chest, I have already done this following failure of lifters about 10k miles ago. This is preventative maintenance to avoid lifter failure again.

You can do it with the engine in the frame, the rear bolt on the rear cylinder is the problem, but it is possible.  When you get that one loose you may not have enough space to pull the bolt out until you move the cover some. 

The ratcheting wrench that you mentioned does work, just make sure to stop using it before it gets too close to the frame and can't be removed.

Cut a good Allen wrench and be done

Hi John,

If your only going to change out the Lifters then the easy option as suggested by an earlier member is to buy adjustable pushrods, cut the old ones off with bolt croppers (if you don't have croppers use a cutting disc, carefully making sure nothing goes down the lifter bores), if you have not decided on the lifters, go for the S&S  lifters (without HL2T kit), do not buy new Harley ones.

If you decide to go the removing the rocker box route, get a good quality allen wrench (the rocker box bolts have a allen wrench fitting and also a standard imperial hex bolt head) and using a Dremel and fine cutting disc cut it down so it protrudes just enough from the bolt to enable you to get a small ring spanner on it, you can also get a little extra room if you undo the front motor mount bracket from the front of the engine, but make sure you support the engine.

As suggested earlier while your in that deep you may want to change out the inner cam bearings (a major source of problems with these engines, if they break they often cause major damage) it means removing your exhaust, cam cover and the removal of the camplate with cams, if you have a workshop manual its not as difficult as it sounds, you will need a cam bearing removal tool and installer.

Its a time consuming fiddly job, you just need a little patience, Good luck.

Trick is to loosen the engine stabiliser at the front, then have someone push the engine over at the top to give room to pull the bolt out past the frame.

Sounds interesting, never tried that and I have gotten in there at least a couple of dozen times on various bikes.
