I have a 1990 745 non-turbo (185K) and I want to order the correct engine service manual. I looked at the Volvo website to order but I notice two manuals: TP30871/1 and TP31003/1. Both of them are described as B200/B230 Fault Tracing, Repair and Maintenance. Obviously they are different - how are they different? Which one is the main engine manual?

I just did a timing belt (all belts) and tensioner job, on my 1988 244. The manual #TP 300871/1 was invaluable. Good Pics, and correct torque on crank pulley. (Bentley shows 1/6 turn as 90 degrees). I also have the special tool #5284. Since I wound up doing removal,replacement, removal,replacement several times, and I have 3 daily driver 240's, the tool is worth the cost. The rope trick is - for me - second best.

Call 1-800-25-VOLVO and see if that's Ken Cook, the manual publisher. If you can get a human answer, you can ask about manuals.

The other important manual to get is the wiring diagrams book. The pictorials of ALL the sub-systems are not repeated in Haynes or Bentley, and I have found them invaluable.

Good Luck,

Bob

Depends on what you want to do: the manuals cover a multitude of procedures. What is it you had in mind?

Oops! Meant to put that in the first post. I'm getting ready to replace the timing belt, cam and crank seals and tensioner.

It covers it pretty well and there's even pictures on the web if you search for them.

I've fabricated seal installers with PVC pipe or joint fittings to tap in the crank and cam and intermediate seals. I prefer to install them with a little bit of red loctite around the outside of the seal and lubriplate grease on the inside/back of seal around the little spring.

If your engine has more than 120K miles on it with the OEM timing belt tensioner, it's probably a good idea to replace the tensioner (amazing how quiet a new one is!) although I've never seen Volvo recommend that. General rule of thumb is to replace the tensioner every second belt change.
