Is the Triumph cylinder liner removal the best tool to get the liners out?
I have an issue where coolant is getting into the oil. I pulled the head off and I can’t see anything wrong with the head gasket. Wondering if it’s a leaking liner where it seals to the block or maybe one is cracked? I thought it might be the water pump seal, but a replacement pump didn’t stop the leak.

The believe only advantage to using factory puller is it's easier to pull the liners while still in the bike. I've never seen one but someone said it expands, but I can't say that's correct. I had a 5/8 piece of metal turned .250 bigger than the bore, drill a 1/2 hole through center and pull liner out. It usually doesn't take much force to remove the liners. If you have a problem just put a pipe a little bigger than the liner on block surface and another plate and pull them out.
 
Rarely get to see the cylinder bores with the liners removed. Not too many fellows have pulled them. Would appreciate any pics. Are they wet sleeves?
 
You can indeed make your own tool to do it. Like most Triumph tools. I posted the dims of the Triumph tool years ago, could dig it up so people could make their own.
Someone said they used to run some gaffer tape around the inside of the sleeve and then manually turn crank so piston catches the tape and pushes the sleeve up.
I've only ever used the tool, as the first time I operated on one of these engines i didn't have time for any delays and had to be prepared with military precision.

Edit: found the old pics, please excuse the dark background

The coolant is pumped up from the water pump through that chromed pipe into the front top RHS corner of the upper crankcase, and it comes in around the cylinder sleeves/liners through those 3 holes at the (as we view it here below) bottom of the liner bores in the upper crankcase.
So if one were to use too much RTV silicone when fitting the liners, it can be pushed out and restrict the flow of coolant in around the associated sleeve.
Coolant then moves up through the head then and out through the thermostat/bypass on the LHS of the head, through the pipe to the top/lower RHS of the rad.

Not wet sleeved, that's why they're easier to pull, and they tell you to seal bottom surface around the liner with titebond sealer. They are a heathy made liner with a wide top sealing surface.

Thank you, R-III-R, pictures are worth a thousand words, thanks for showing them. Good explanation of coolant flow.
 
Just adding to what pros already said works. As stated above Tape works, pull piston upside down through top if piston is off crank, if not like R-111-R said use crank and piston to push it up, using tape on liner walls, prep work matters, tapes gotta stick.
