This is embarrassing
Yep, I did it. or at least i think it did. I'd like to think the previous owner loosened it up for me.
How have others remedied this in the past? Anyone try JB Weld to make new threads? I'm a little worried about gluing the entire outlet shut.
Heli-Coils?
New pump?

Many have used helicoils to repair the threads and that is the best way I know of.
Jim Hobbs made some screws that were a bit longer with more thread engagement to help avoid stripping.
It may be that Simon H is setting up to repair stripped threads but he needs to tell that on his own.... I may have misinterpreted what I read.

Stripped threads in the case or oil pump?

In the oil pump, not case. After looking up heli-coils, I found this:

I'm thinking of giving it a try. I have a spare oil pump just in case, but its from an H1 (or so it says on the cam). Is there a difference between these pumps?

Yes, different pumps have different output.

Modern oil means you can use one with less output than original and be ok.

Timeserts are preferred to helicoils by many.

Timesert have been highly recommended on other boards I frequent. I'm thinking about using them on a transmission that some gorilla got to when last servicing the filter in it.

Timeserts are easier to install than heli coils. ( a special tool is not needed ) Plus most people don't realize there are two styles of helicoils, free and locking. The locking have a small flat spot and stay in place better.

wow....never heard of timesert...I would give it a shot. I have a stripped pump I got with an ebay deal long ago. Looks like fastenall carries them and they deliver to my work. What sizes would be needed/best for the three oil lines and the tank line on an H1 pump.? http://www.timesert.com/html/mtrcsert.html

I just looked at a spare oil pump I have ( H1 )

The standard kit timesert repair inserts will be perfect for three out out the four M6-1.0 threaded holes. The one that will give problems is the one directly over the plunger rod.

I "guess" you could disassemble the pump, drill and tap the holes and then shorten the one over the rod.
**** They do not recommend shortening the timeserts since the locking portion of the inserts is on the bottom.

16. Can TIME-SERT inserts be shortened for length?
No! you cannot cut off the bottom or top of the inserts for these reasons. The top has a flange which give the insert a place to sit for positive placement. The bottom of the insert is the locking portion.


M6x1.0 thread
kit #1610

comes with 9.4mm length inserts


Now if this was my own personal pump on my own motorcycle, I would shorten the timesert and use a thread locking agent on the shortened insert. YOU decide if this would be what YOU want to do.

My old pump had helicoils and it worked fine but I came across another pump some years bad and am using it now with care... I switched to statoseals too and they just give me a warm and fuzzy all over!
