I am trying to remove the timing cover and have got to the rear part where (apparently) tool D782 is used to unlock the thing from the cam gear.

Does anyone know where I can purchase, rent, or fabricate this tool? I can't seem to find any information on it in FAQs or google.

TIA
eric

Hi Eric,

It is good to see that you are starting the job right - carefully and slowly. I don't want to stop you progressing in the right direction of asking before applying an appropriate amount of effort, but I have never used this particular tool because it has never been necessary. The timing cover hangs up on the bike because of two things; sealing goop and friction. The friction is because it is located on the ends of two shafts and two little locating stubs that pass oil into the cover down the bottom.

I CAREFULLY use a piece of clean cut wood and the smallest little hammer I have to find the places where the cover overhangs a little and TAP it gently until the stiction of the goop breaks. I then use finger nails to pull it off. Never 'pry' at it by going between the gasket surfaces unless you like oil leaks and broken covers.

Remember:

1/ All screws out?
2/ ONLY tap it gently with wrist movement!
3/ Pull it off parallel for a good inch to clear the shaft ends.

HTH,

Blapper redwine

Lean the bike toward the drive side unless you want the cam drive idler gear to fall out and roll away.

To remove the AA unit I thread a bolt [5/16 ?] into the centre of the AAU with a short length of chain attached and gently use this as a slide hammer to release the taper in the end of the exh cam.

Eric -
Tiger is right. I have the tool, but never use it. A 5/16-24 UNF or 5/16-26 bolt, 3/4 long screwed into the end of the AAU will do the trick. Simply tap very lightly on the bolt from the N,S, E & W directions, alternating as you go, with a VERY small hammer and the AAU will magically fall out.

If you beat on it, you'll warp the taper on the AAU and it will never run true again, ergo the special tool. But if you go slow and use a multi-directional tapping or a puller as Tiger suggests you'll have it.

And as Tiger reminds.... do this work on the side stand to keep the gears in place or you may be sorry.

Thanks fellas. I was thinking of filming the process, taking a large sledge and tapping it very gently on the thing, just for a giggle, but efficiency got the better of me and I just removed the thing with some gentle raps and a pair of pliers.

I am taking pause now and have read ahead a few pages. It appears that in order to continue, I need some pullers and special tools.

Namely:
Extractor 61-6019
Special tools Z79, D2213, 61-6064, and 61-6046.

These look pretty specialised and I am willing to purchase them to do the job right, but cannot seem to find a source to sell them to me. Advice?

The majority of the tools are available from dealers or eBay. The rarest one was the drive side roller outer race extractor but this has appeared on the Tri-Cor site.

MAP, British Only, Mitch Klempf, E and V Engineering, Tri-Cor, Coventry Spares, Northern Eagle, Fair Spares,many others ... Google "Triumph Motorcycle Tool". The mind boggles at the excellent vendors out there currently. Any or all would be happy to have your business, and we've got your back if things seem shady, or you need advice.

When these bikes were current production there were precious few good sources for parts, tools and advice regarding these bikes. We truly live in the golden age for vintage British motorcycle ownership. Long live the Internet, and the Pacific Rim manufacturing dynasty! And the enthusiasts who live (and make a living from) these machines.

You really don't need to thread a bolt into the AA unit. Just loosen the center bolt which fixes it to the camshaft...not the pinion....pull it out about halfway, and tap the bolt head laterally. TAP is not SMACK. Asymmetrical force will break loose most tapers. If not, then asymmetrical heating AND asymmetrical force. And asymmetrical yelling and cursing. Worked on a Husky 250 back in the sixties.


What, me worry?

Eric -
I thought you were just removing the timing cover ??? No other tools are needed to continue that job.

But if you were really out to do an engine rebuild please consider that if removal of the AAU "stumped" you, then maybe you should consider not going any further. You have the very real possibility of destroying more parts than you repair.

Try to keep up RF. Eric has a seized 650 and now that he knows what happened he wants to try and disassemble and rebuild his engine for himself.

Special tools will be required to get there without resorting to a hacksaw to part the primary chain which already occurred if you were not present for the discussion so far.

What tools for disassembly do you recommend for Eric.... you have so much more experience than most here... and for successful reassembly as well??? Can you remember the time before this forum??? And before Beno???

Yes, I can. Richard wrote technical articles in the original TIOC Newsletter back in the early 80's. That was even before Fred Largerquist. I was just reading one of his early technicl articles just the other day.

I personally don't like to tap on the bolt or the AAU. My suggestion would be to go to Harbor Freight buy a cheap slide hammer, attach a 5/16 bolt to the end of it, screw this into the AAU and just pop it off. If you want to do it cheaper just make you own slide hammer out of a 5/16 bolt and a piece of steel, aluminum or brass with a hole drilled in the center. Unless you don't ride the bike or put on an electronic ignition you will be taking this off again.

Yeah, maybe in fifty or sixty thousand miles....IF you lube it correctly once in a great while, and assuming you are starting with a good one. You'll be pulling it to change the seal, no other reason.
