coolant hoses

[nert]

Hi!
I am at 74,000 miles and performing another 20,000 mile service. I think after the first 20,000 service, Triumph says additional valve adjustment not needed. But, im here, doing the fuel and air filter, spark plugs, WHY not check the valve clearances.? I am glad I did, the valves have grown loose. THATS another story, I thought they would grow tight, as the valves pound them selves into their seats, and in effect reduce the valve clearance.  But, maybe, camshaft wear, bucket wear, and cam bridge cover wear increase the clearance as mileage builds?
Would like to hear thoughts or experience with other higher mileage valve clearance checks.

I have 52 years of professionally turning wrenches on everything form class 8 trucks, hydraulic machinery, to old farm equipment, and vintage motorcycles. Service on this Triumph cycle is involved!!  Since im there/here, I want to replace the 2 coolant hoses. They are 10 years old and stiffer then a wedding promise. Has any one replaced these hoses? The opposite end of the radiator hose ends are buried in the back side of the engine. Do I have to remove the alternator, and the brake electro/hydraulic thing? IS there a trick to be shared? I appreciate any information you can share.
Thank you.

I bought both coolant hoses and all the other hoses with the intent of replacing them at the 40K service on my '13 in late March before the Arkansas get together since they were 10 years old.  After careful scrutiny the only solution I could see was removing the fuel rail, the throttle bodies, and maybe something else to even access where they connected to the engine.  Needless to say, I didn't do that partly due to the time limitation and partly due to the manual procedure for replacing the coolant requiring "a helper to tilt the bike from side to side, check the coolant, repeat if necessary, check the coolant, repeat if necessary, blah, blah, blah,.  Not having a capable helper available convinced me to let well enough alone.  Just as well since the '13 had the catastrophic engine failure the first riding day in Arkansas and came home in a UHaul to rest forever more.  Just gotta love engineers!

No, the alternator does not need to be removed from its housing. But if you have to remove the injection assembly to remove and replace the end of the tube that goes to the thermostat.

To bleed the cooling circuit it is not necessary to tilt the motorcycle, so a single person can extract the air from the circuit perfectly. Of course, the screw (cap) of the engine block must be opened, first so that all the coolant comes out through that screw hole and once the work is finished and filled with new coolant, open the screw of the engine block so that it some coolant comes out, close it again and then continue according to the workshop manual to proceed to thumb the circuit, I simply open the cap (screw) of the radiator in the lower left part and there is no air left in the cooling circuit.

In the following photo you can see the screw (plug) of the engine block that I am referring to

In these other photos, you will be able to give a slight idea of how to proceed to replace the cooling tubes.

SNIP .....

Who did the last valve adjustment ?

I'm sure Coconut will jump in here but I thought there was an error in the maintenance schedule and the valve clearances should be checked every 20k miles (32k kms). Happy to be corrected on this.

....... JUMP !

"Check and adjust Valve Clearances" has always has been every 20,000 miles / 32,000 kms.

The Camshaft Timing Check and Adjust HAS been changed
from "only first 20,000 mile (32,000km) service"
to : EVERY 20,000 mile (32,000km) service. 

This is a timely reminder for anyone carrying out their own maintenance, that there are
a number of errors in the official Triumph Service Manual that could catch you out ! 

For those that still don't know, I compiled and maintain a LIST of all the known errors
across all of the Triumph publications for "our" Model of Trophy,
including the Service Manual, Owners Handbook ( both versions ), Audio Handbook, and Service Booklet.

The Lists or errors ( not the manuals ) can be downloaded from a Topic in the Forum here :

Owners, Audio, and Service Handbooks + Service Manual errata

I strongly urge anyone using the Service Manual in particular, to download the List
and use it to correct the original incorrect entries in the Triumph publication.

Cheers
