Need help replacing water pump and timing belt on '92 HDJ81

[ScottJacob]

Hey y'all, my water pump recently started leaking after I did a coolant flush. I ordered the parts to replace the water pump, timing belt, alternator belts and turbo water hose. Anything else that people would recommend that I replace while doing this job? Also, can anyone point me to a nice step-by-step instruction on how to go about this job? I've never done this before so preferably something that is easy to understand. Thanks!

Water pump studs timing belt tensioner it's fairly straight forward when you get TDC on number 1 make sure the marks line up before pulling and replacing belt.
Take your time double check everything and use a inch/lb torque wrench if your not savory with aluminum or plastic casings.

Check out the FSMs in the FAQ section, they will give you all the info you need to do the job

While you are in there replace the cam shaft seal if you like.

And you're going to need a small amount of FIPG (formed in place gasket) to seal the cover back up.

The top timing cover has to come off. Key notes,
1)the camshaft has an area in between #1 and #2 for a wrench to hold the camshaft solid while taking the cam gear off. Sorry, cant remember size but use a large adjustable to hold.
2) the plate has FIPG (black, not Orange) on it, you will need to get a tube from Toyota
3) 90311-32020 is the cam timing seal- you will need one of those.

pretty simple job except the spring on timing tensioner. getting them back on is a PITA. 90507-27003 is the spring number if you want an extra.
When was your belt changed?

Georg at Valley Hybrids made up a tool which works very well for putting the tensioner spring back on. Cut a small, standard brake tool in half and weld a T bar on each end. Not having a welder anymore, I took my brake tool and just bent it 90 degrees. Also grind down the spoon end slightly to give more room for the spring to slip over. See the FSM how to use it, but basically it the same procedure as putting the spring back on a drum brake.
