What tools will you need to tear down your TRW 500? So here ya go. You will need two extractors/pullers to disassemble your TRW 500. This is a little confusing so bear with me. If you are smart you have found the workshop manual for your TRW online. If you have not, then email me. The official manual lists 3 pullers; the cam shaft, the crank shaft, and the clutch hub puller. The part numbers listed in the manual are D178/183, ST/1940, and D.50, respectively. These numbers mean nothing to Triumph parts houses scattered around the glode. My guess is that these part numbers where based on military specs, as the bike was never sold by Triumph on the civilian market.
But never fear, I have found the civilian equivalents to two of these pullers, and a work around for the third! First, for the the camwheel you will want to use the equivalent puller for the crank pinion of the unit 'C' model twins ONLY, meaning 500cc, which have a threaded pinion. Sorry, I don't have an official part number. If I find one, I will be sure to post it.
For the hub you will want the standard clutch hub puller 46-1982 which is the puller for the 500 650 and 750.
I was unable to find the puller for the crank shaft wheel, but after a stroke of genius I discovered (I was not the first) you can thread the clutch hub onto the cam gear, then use a set of 3 jaw pullers to remove this gear. Here a few pics...

I finished up the tear down of the motor last week. The next post will include notes on that process.
I'd love to know more about this rebuild! I'm the proud, new owner of a trw. Do you have the manuals? Any more tool and rebuild tips? Where did you order most of your parts? Thanks!!!

ReplyDeleteI'M NOW FULFILL FINANCIALLY BECAUSE OF THE LOAN I GOT FROM LFDS .I would like to bring this to the notice of the public about how i came in contact with LFDS after i lost my job and being denied loan by my bank and other financial institution due to my credit score. I could not pay my children's fees. I was behind on bills, about to be thrown out of the house due to my inability to pay my rent, It was during this period my kids were taken from me by foster care. Then i set out to seek for funds online where i lost $3,670 that i borrowed from friends which i was rip off by two online loan companies. Until i read about:Le_Meridian Funding Service (lfdsloans@outlook.com / lfdsloans@lemeridianfds.com) somewhere on the internet, Still wasn't convince because of what i have been through until a relative of mine who is a clergy also told me about the ongoing loan scheme of LFDS at a very low interest rate of 1.9%% and lovely repayment terms without penalty for default of payment. I have no choice than to also contact them which i did through text +1-989-394-3740 and Mr Benjamin responded back to me That day was the I'M best and greatest day of my life which can never be forgotten when i receive a credit alert of $400,000.00 Usd loan amount i applied for. I utilized the loan effectively to pay up my debts and to start up a business and today i and my kids are so happy and fulfill. You can as well contact them through email: (lfdsloans@outlook.com / lfdsloans@lemeridianfds.com) WhatsApptext helpline: +1-989-394-3740 Why am i doing this? I am doing this to save as many that are in need of a loan not to be victim of scams on the internet. Thanks and God bless you all, I'm Oleksander Artem from Horizon Park BC , Ukrain.
