After replacing my oil pump I thought it would be wise to check the cam chain tension. Looked everywhere but the right place.
Would someone please direct me to where I can read the tension setting procedure?

Specifically, is the cam chain tension checked and set by rotating the camshaft counter clockwise. Thank you

All good on 3/16" play. I have the iwis chain. Rubber padded tensioner on the short list

Thank you!
 
Good to see you are using the plate tool for stabilizing the intermediate pinion. Risk of not using this is wallowing out the pinion bearing hole in the casing and you'll not get the chain tension correct without it help steady.

You guys taught me....................xoxoxoxo
 
I don't have any problems with adjustments been running an auto timing chain adjuster for over 35 years now and it pushes down on the chain not up like the stock set up.

I use the auto adjuster that Comstock invented and it worked for me (80 k miles) but as ludwig stated with the iwis chain and the rubber cam chain tensioner, that is all that is needed.
The problem was the Renolds chain (made in England... not!) that was manufactured and farmed out to the lowest common denominator called Chyna. buy Iwis chain.

Well 35+ years ago not sure the Iwis chains where around for the Norton or Andy the chainman for that matter, the old original Renold chains were good back then made in England, but next time I take my timing cover off for any reason I be replacing the Renolds chain with a Iwis chain for sure, but I still be using the auto chain adjuster been over 14 yrs now since I had the timing case off, I might put an order in for a timing chain and a duplex chain for the primary from Jason the chainman, I brought my last rear chain off Andy before he retired.

Yes Ash,
Renolds chain was good in its day. 1960-1970. and then it went to a company name to how can we produce the product as cheaply as possible and still using that name to make money for the CEO's of a failing company.

Well I have only been around bikes since leaving high school in 1974 and buying my first Honda dirt bike at 15 and my new 74 850 Commando in June 76 old new stock, but I have a love for all British bikes of the times as well my newer models of the Thruxtons and a lot of old parts companies taken over buy cheaper for profits companies using the old company names same as the new Triumphs not the same as the old Triumphs just look at the way the bottom line goes to the Triumph H I like the older style embelin better and the old tank badges.
Everything changes and not always to the better, I am old school in everything I do, I am not changing for no one.

Christ just look at Harley right now.... Go woke go broke.
 
Has any body ever had an intermediate pinion shaft come out . Mine is not walowed out. Cant feel much of any wiggle when pushing side to side. was wondering if the shaft could be built up with like a flame spray or gun blue or oh I got it, just dip the end in battery acid for a little bit. Only need like a thousands or jb weld. however it makes disasembly and reassembly easy.

On the loose one I found the shaft was undersize and a new shaft restored the tight fit.
 
The rubber backed tensioner brings its own issues, from what I have read in threads on this forum.
The chain side links will eat into the rubber until the rollers makes contact. At which point (or prior to) you need to re-adjust the chain.
So not exactly no-maintenance, IMHO.
I would not include this on the list of must do upgrades.

Hmmm interesting. Same thing happened when I opened up the engine cases and found the main bearings with no interfiernce off by .001 but I got the new bearings and they were .003 thou bigger booommmm
