I have a Delco Remy(part#1109064) starter that came with a motor I purchased. I had it tested and works fine. However I want to make sure it'll work with my flexplate. Can someone tell me what number toothed plate this one will fit? I have done a search here as well as gone to delcoremy.com and ran the part number, says its invalid. I was hoping someone here had a reference book or another idea Thanks in advance Cory
There are two basic types ... 1 ) a 153 tooth flywheel which uses a straight across pattern starter 2 ) a 168 tooth flywheel ... which uses a staggered pattern starter, Count the teeth on your flywheel and then check the pattern on your starter
Count the teeth on the flywheel ( you need 168 teeth ) and Like 36-3window says ... use the correct bolts. I buy mine at the Chevrolet dealer ... but most speed shops have them ARP makes a NICE set ... which the speed shop can get. Summit Racing has them also. .
When I was having trouble with a SBC starter engaging properly, I went to Advance Auto(Discount) and pulled all of the GM starters out on the floor. I think there are about 12-13 different configurations. I Knew how I wanted it to mesh, and picked out the right one, NO more trouble.
Another way to see what's what....... On starters made B4 about 1981....10MT series... Housing bolt SHANK is .375" (3/8") with 3/8 NF threads Aluminum nose housing 2 long bolts = use with a 168 tooth flywheel/flexplate 1 long & 1 short bolt = use with a 153 tooth flywheel/flexplate Cast iron housing 1 intermediate and one longer bolt = 168 tooth (U wont find many of these around) 1981 or so and later ar METRIC starters...that is they used metric screws (sometimes)....... Housing bolt shank is 10MM (.395") with 3/8" NF threads The bolts DO NOT INTERCHANGE. Measure the holes in the nose housing. Use the correct bolts. At the end of the day give the 10MT the flotation test and then use a PMG (permanent magnet) style late model GM starter.
The starter housing is drilled to use the 10 mm bolts . 10mm is slightly larger than 3/8 ". You cannot put 10 mm bolts into a 3/8" housing BUT you can put 3/8" bolts into a 10mm housing, causing the starter to move around and eating up your flexplate ! #3510 OR 3510M... be careful ! Also, just a heads up..The permanent magnet GM starters all seem use 10mm bolts.... Just a heads up from an old , retired parts man.. Dave
Plus that knurling on the end towards the threads help keep the starter nose from moving, since knurling increase's the size of the bolt slightly.
Wow, I asked because I just put a 3/8 co**** thread bolt in one of the holes and it seemed to work fine. MY problem was the aforementioned issue of the two different starters. I thought they would all be the same after say 1963 or so. Boy was I wrong.
Deyo, the std 3/8 co**** bolt will work , BUT.... you need the knurl down at the base to locate the starter precisly where it belongs. The knurl extends up into the block about 3/8" (there is a machined recess) and fits the starter housing very tight.. This is why I mentioned the difference between the metric and std bolt diameter. Using a metric housing with the 3/8" will allow the starter to walk around.. As will using a std 3/8" housing with NON knurled bolts.. Dave
