I should be getting a rebuilt head preety soon to install on my 617.952 and have a few question.
1. My prechambers look good besides being a little carboned up. What the best way to clean them or should I put in new ones. Are new seal rings always used and if so there seems to be two sizes, 2.0 mm and 2.3. Mine measure out at 2.0mm but maybe thats what the 2.3 rings flaten out to?
2. What is the torque value for the PC collers
3. I have a 24 volt system and the the glow plugs are stamped 18V. Bosch part # 0 250 200 064 18V. Can't seem to find any

Thanks Ray

Anybody?

1. You need to look at the shafts that hold the distribution ball. They become loose in the outside shell with age and there is a danger that the shaft will fall out of the housing and the ball and shaft will fall to the bottom of the prechamber. The cost of a new set is $300. If you plan to keep the vehicle for another 100K miles, I do believe it's worth the expense.

2. The threaded ring that holds the PC has a torque of between 110 and 130 ft.-lb. Surprisingly high, but, it's in the 617.95 manual.

3. This is news to me. I wasn't aware of any 24 volt systems on these vehicles.

Thanks, the engine is in a Hagglunds BV206

You could alway use 12 volt GPs and tap the timer supply between the two batteries (12v).

ah... Thats an interesting setup you have there... Is it a stationary engine or something like that?

Cool vehicle!
